Employers and Employees Responsibility

The installation and maintenance of gas ducted

heating units, particularly at height, has the

potential to create Occupational Health and Safety

issues for those involved. Installers are advised to

ensure they are familiar with relevant State and

Federal legislation, such as Acts, Regulations,

approved Codes of Practice and Australian

Standards, which offer practical guidance on these

health and safety issues. Compliance with these

regulations will require appropriate work practices,

equipment, training and qualification of workers.

Seeley International provides the following

information as a guide to contractors and

employees to assist in minimising risk.

Risk Assessment

A risk assessment of all hazardous tasks is required

under legislation. A risk assessment is an essential

element that should be conducted before the

commencement of work, to identify and eliminate

the risk of falls and other risks, or to minimise these

risks by implementing control measures. This does

not need to be a complicated process - it is a matter

of assessing the job to be done and considering

what actions are necessary so the person doing the

job does not injure themselves.

This should be considered in terms of:

What are the chances of an incident occurring?

What could the possible consequences be?

What can be done to reduce, or better still,

eliminate the risk?

HANDLING THE HEATER

The heater has lifting lugs for crane hook-up. Hooks, jacks, or chains must not be applied around casing or

control box.

POSITIONING THE HEATER

Heater should be installed so that it is level. Allow 1200mm clearance at the front and control side of the

heater and 500mm on the bottom, top, and other side. Air intake to the unit should not be restricted in

any manner.

Wiring Electrical connections must be in accordance with all relevant Australian standards.

Avoid quiet areas:

Directly above, below or outside bedrooms, living room, lounge room, dining room etc. Some points to

consider

Preferred installation locations:

Above, below or outside laundry, bathroom, kitchen, garage etc’

PIPING

Gas piping should be sized adequately, in accordance with the Australian Gas Association’s installation code

AG501.

Safety Information


SOME POINTS TO CONSIDER

Some points to consider when working on or in a roof

What is the best and safest access to the roof and working areas?

What condition is the roof in? Should the roof structure and surface be checked?

Does the worker have appropriate footwear?

Are all power cables/extension leads safe and appropriately rated?

Are all ladders, tools and equipment suitable and in good condition?

Where ladders are to be used, is there a firm, stable base for them to stand on? Can they be tied or

secured in some way at the top?

Is there a roof anchor to attach a harness and lanyard to? If so, instruction should be issued for the

use of an approved harness or only suitably trained people used.

Are all tools and materials being used, prevented from slipping and falling onto a person at ground

level? Is the area below the work area suitably protected to prevent people entering this area?

Does the work schedule take into account weather conditions, allowing for work to be suspended in

high winds, thunder storms/lightning or other types of weather giving wet, slippery surfaces?

Is there an on-going safety check system of harnesses, ropes, ladders and access/lifting equipment,

and any anchor points on roofs before the commencement of work?

Is there a system which prevents employees from working on or in roofs if they are unwell or under

the influence of drugs or alcohol?

Are there any special conditions to consider i.e. excessive roof pitch, limited ground area, fragile roof,

electrical power line

GENERAL INFORMATION


AIRA HCV/R series heater/cooler units are an indirect fired gas warm air heater with an evaporative cooler

section attached. This unit can be used in closed in areas such as offices, shops, restaurants, schools,

Take-away food stores, glasshouses etc. HCV/R units can be wired up to suit site condition requirements

and options. These options include: Single or two speed motors, duct louvers, electronic modulating gas

trains, return air, etc.

The heating section usually consists of a stainless steel indirect fired heat exchanger, RAM - 5EM7-01 flame

controller, electronic ignition, high limit switches and pre and post heat switches. A room thermostat is

connected to read heat requirement in the application. As the temperature in the room and the thermostat

set position get closer the gas valve modulates. There are many different options available to ensure

suitability of the equipment to suit a particular site.

Evaporative cooling is via Celpad water saturated pads. This type of pad has more stability, longer life and

airflow as compared to older aspen style pads and less maintenance is required. A Variety of covers can

be provided including marine grade louvre protection, fire screens, insect screens and filters.

Ventilation is achieved by simply turning the fan on without the water pump running. This mode of

operation is used when ambient temperature can be utilised to cool down or heat up the work area. I.e. if

the work area is has machinery that is generating heat above 22°c and the ambient temperature is 18°C

with high humidity the ventilation mode can be selected.

With a Return air function installed, gas consumption is reduced. Supply air is heated and then returned

through the heat exchanger to be reheated. If the heater is fitted with a modulating gas train, the burner

will modulate down to low fire and then turn off when the room thermostat reaches the pre selected

temperature. When the unit is operating in return air mode, fresh air is still fed into the heated area at a

lower rate to ensure air remains fresh.

As the AIRA/HCV/R is indirectly fired the flue gasses must be flued to the atmosphere. The flues must be

clear of any air intakes, eaves etc. as per Australian gas regulations. The efficiency of a heat exchanger

unit is approximately 80%.

Commissioning is to be done by an experienced 'A' Type approved service person and does not normally

require an inspection by the Office of Gas Safety (OGS).

Control of the Unit can be via a number of methods. The standard controller is a 5 gang wall mount switch

allowing the unit to operate in high cool/low cool/ventilation/heat modes. Some people find a rotary dial

easier to operate. The unit can also be controlled via push button control or via Building management

system (BMS) or Variable speed drive (VSD). Controls are not designed to switch quickly between heating

cooling and ventilating but graduate temperature toward desired outcome. Please contact Factory for

clarification re control wiring.

WALL CONTROL OPTIONS

The HCV can be controlled a variety of ways.

Standard supplied control is a 5 switch wall mount gang switch.

1.1 Remote selector switch panel functions.

The switch panel consists of five individually marker rocker switches and a warning lamp. The

switch panel is specially designed for use with HCV units, and gives a selection range of ‘OFF, LOW

VENT, HIGH VENT, LOW COOL, HIGH COOL and HEAT.’ The switch marked ‘PRESS’ is used to reset

the appliance when the red warning light is alight. Switch settings for unit control are as follows:-

OFF FAN SWITCH OFF, OTHER SWITCHES ANY POSITION.

LOW VENT FAN SWITCH ON, COOL SWITCH OFF, HEAT SWITCH OFF, HIGH-LOW

SWITCH IN LOW POSITION

HIGH VENT FAN SWITCH ON, COOL SWITCH OFF, HEAT SWITCHOFF, HIGH-LOW SWITCH

IN HIGH POSITION.

HIGH COOL FAN SWITCH ON, COOL SWITCH ON, HEAT SWITCH OFF, HIGH-LOW SWITCH

IN HIGH POSITION.

HEAT FAN SWITCHON, COOL SWITCH OFF, HEAT SWITCH ON, HIGH-LOW SWITCH

IN LOW POSITION. Note that heating will not operate with high-low switch in

high position.

1.2 Optional Rotary remote selector switch functions.

Hi-Cool Evaporative cooling, dampers open, maximum air delivery

Lo-Cool Evaporative cooling, dampers closed to preset position, corresponding

decrease in air volume.

Hi-Vent Fresh air ventilation, dampers open, maximum air delivery.

Lo-Vent Fresh air ventilation, air quantity reduced as for ‘Lo-Cool’.

Heat Fresh air ventilation together with heating to maintain comfort heating to an

area whilst providing required air changes of fresh air per hour.

These switches are specially designed and manufactured for Aira HCV units for special applications.

They give an operating range of Hi-Vent, Lo-Vent, Hi-Cool and Heat.

Note: Other Controls can be designed and or supplied on request for specialist applications. VSD

drive can be supplied loose (Programing by others) or shielded cable installed. Usually a VSD drive

is fitted to a single speed motor.



GENERAL OPERATION

1. Ensure that all fuses on switchboard are in position.

2. Ensure isolating switch for unit situated inside the heater section is in “ON” position.

3. Set room thermostat to 21°C. This may be varied later if desired.

4. The limit air thermostat will have been set during commissioning to give the desired comfort air off

temperature.

5. Heat – unit operates and discharge dampers close to predetermined position to give design

temperature rises across unit or design L/sec air flow. Provided entering air temperature is below

duct thermostat setting, a gas control valve will vary the gas flame to maintain a controlled air off

temperature.

6. Should the burner fail to operate and the red lockout light comes on, wait five minutes after

observing red light to ensure unit is venting and then press and release reset button. Unit should

relight and operate.

7. When selector is turned “OFF” the fan may continue to run for up to five minutes to allow for cooling

down of the heat exchanger.

8. Vent / Set selector switch to “High”. Fan motor only will operate. Heating section is de-energised.

9. Set selector switch to “Low”. Dampers will close to same position as for heating and fan will operate

at reduced air volume. Heating section is de-energised.

10. Cool – Unit operates on “High” or “Low” air output (damper opening as in high and low vent). Water

pump and fan operate. Heating section is de-energised.

11. To shut down gas burners completely, close main stop cock at unit and turnoff isolating switch in the

heater section of the unit.

HCVR RETURN AIR MODELS

The HCVR Return Air Models are designed to allow full fresh air on cooling as per standard HCV, but then

allow economical return air heating during the heating mode. This is achieved by motorized dampers

automatically closing off the cooling fresh air section and opening a motorised return air heat damper at

the heating section of unit. Dampers can also be set proportionally to allow some fresh air during heating.

Standard control on Return Air Models is on/off gas control operated to a standard on/off room thermostat.

Optional electric Modulation is available to modulate burner operation in conjunction with a compatible 0-

10 volt Modulating room thermostat. Leaving air tempering is not required on Return Air models due to the

recirculated room air temperature.

IMPORTANT: If heater will not operate after carrying out instructions as detained above,

contact the installer or Aira for further advice.

During normal operation in cooling mode it is important that the water bleed-off is operating and is not

shut off or blocked. This bleed-off will prevent an accumulation of salts and solids in the unit. Bleed off also

ensures a constant supply of fresh water into the cooler. A Dump valve is also recommended to ensure no

water remains within cooler when unit not in use. Aira coolers have a very small water sump ensuring little

water is wasted in a dumping cycle.

INSTALLATION INSTRUCTIONS



INSTALLATION GUIDELINES

LPG Appliances subject to gas supply authority inspection.

The building structure should be able to carry the operating weight of unit, all relevant stands and

ductwork, as well as service and installation personnel.

Keep unit clear of any heating flues, kitchen exhaust, toilet exhaust, sewerage vent pipes etc. Keep ample

clearance on all air inlet sides of unit. A basic rule is not less than 1 meter. Do not site the unit over or

near a skylight. Installation or service personnel could fall through causing damage and injury. Roof stand

kits are available for all models. Ensure that stand is fitted such that the unit remains level.

When slinging any unit for a crane lift, ensure that an adequate sized rope sling is used. The sling should

be wrapped round the bottom of the unit. DO NOT tie slings around and under the roof (top) panel or

through the fan housing. It is advisable when slinging unit to use a bar or wooden spreader laid across the

top of the unit protruding past edges sufficient to stop damage to paint or roof panel.

NOTE: Base panel lifting frames with hooks or eye holes are standard on all sizes of HCV unit.

Consult local building codes for any special requirements. For example: water supply, gas supply, electrical

supply and building structural computations.

Electricity Supply: All electrical connections and wiring must conform to AS3000 and be in

accordance with local requirements.

Flue: Material and installation shall comply with A.G.A Code 5601 (Installation code for Gas

Burning Appliances and Equipment).

Gas Supply: A gas supply line of adequate size shall be connected to the heater. Refer AS 5601

pipe sizing chart.

Water Supply: All water connections and piping must conform to standard codes and local

requirements.

Do not locate unit in an enclosed plant room unless sufficient openings are available to ensure air pressure

in the plant room cannot become negative with all items in the plant room operating. For installations

similar to this, consult fuel supply authority prior to installing. Temperature rise on ”HEAT” must be within

the range of 11°C to 33°C on full flame. Overheating due to incorrect damper setting or restrictive

ductwork may cause problems with heating operation, causing high limit safety control to activate. Gas

burner pressure must be set as per data plate. Firing rate cannot be increase beyond data plate rating. As

part of installation procedure, units must be set up and tested by authorised installer.

INSTALLATION

The following recommendations are not intended to supplant or take precedence over relevant official

regulations.

On receipt of equipment

a) Inspect the unit for any damage caused in transit. Any such damage must be immediately reported

to the shipper of the goods.

b) The unit has been factory tested to check for correct operation of all components. If any part is

obviously missing or damaged, notify the supplier immediately.

c) Check the appliance to ensure that the H.C.V has been supplied for the correct supply, ie Natural,

Towns or LPG gas.

Unit Location

a) The H.C.V is designed essentially as a roof top or external ground mount unit, however, under

certain conditions it can be located in a plant room if positive pressure is maintained by mechanical

ventilation or the heater section is isolated from the cooler section within the plantroom. This

equipment is not designed for long and complex air distribution ductwork and as such the H.C.V

should be located as close as practicable to the points of air distribution. Depending on large



volumes of 100% fresh air, care must be taken to locate the H.C.V clear of kitchen exhausts, etc.

that may allow odour or fume laden air to be drawn into the unit. The prime requisite for the

correct location of an H.C.V is an unrestricted supply of clean fresh air. Recommended clearance

around unit is 1000mm for access to panels and components. Also important to provide clearance

below for drains and dump valve.

b) Provide clearance at each side and ends for air flow and servicing, discharge end top and bottom

panels are removable for servicing. 500mm clearance must be provided between front of unit and

dropper duct.

c) Unit may be mounted directly on a flat roof provided supporting timbers are used lengthwise under

the unit or a prefabricated roof stand is available for pitched roofs. Refer data on room stand

assembly later in manual.

d) If the unit is installed in a plant room, ensure that sufficient clearance is maintained between the

heating section flue and any combustible material. Refer AGA Installation Code AS 5601.

Flue

a) Flue design must conform to AGA requirements. Refer AGA installation Code AS 5601.

e) Where units are installed in plant rooms, straight vertical flues through the roof with no more than

one bend at the appliance are preferred.

f) Horizontal runs if unavoidable should rise not less than 25mm per meter run with a vertical section

of the flue/s extended through the roof. Refer AGA Installation Code AS 5601 for horizontal to

vertical flue length ratios.

g) End of flue pipe/s outdoors must be terminated with an AGA approved cowl.

h) Flue up draft must be confirmed after appliance if fired.

i) New units are supplied with a short 600mm stub , collar and AGA approved cowl.

Gas Supply

a) Provided a gas supply pipe of adequate size to the heater. The screwed inlet to the unit stop cock

must not be used as the size required for the gas line. Gas line size will be dependent upon flow

rate required and line length. Refer AGA Installation Code AS 5601 – Note: HCV50 requires gas

hook up to two points.

j) Maximum inlet gas pressure 3.5 kPa

k) Install a dirt trap (tee, nipple and cap) at connection to each heater.

l) Check all gas connections for leaks using soap solution.

m) Do not overtighten gas valve connection cracked body on inlet side of gas valve will not be covered

by warranty.

Gas Pressures Required (All Units)

NG LPG Manufact. / PNG TLP

Maximum kPa 3.5 3.5 3.5 3.5

Minimum kPa 1.12 2.74 0.67 0.67

Electrical Supply

All electrical connections and wiring must conform to local requirements and AS 3000 Wiring Rules. All

electrical work shall be performed by a registered electrical contractor including:

a) Mains supply

n) Thermostat wiring

o) Selector switch wiring

p) Lockout light wiring

q) Remote reset button wiring



Water Supply

It is essential that an adequate supply of water is available to the unit during the summer when water

consumption will be at a maximum. In area where water is not reticulated, it will be necessary to

install a holding tank above the unit or alternatively to pump water to the unit. A stopcock should be

fitted in the water supply adjacent to the unit for shutting off water supply during service to unit

cooling section.

Water Setup

Water Supply

Ensure that available water supply pressure is not less than 220 kPa (30psi)

The supply pipe should be 12mm copper pipe or similar approved. A ¼ turn ball isolating valve must be

installed on the supply pipe near the unit for ease of maintenance. Do not use duo or non-return valves of

any kind including stop taps with jumper washer.

NOTE: Non return type valves can have an effect on the operation of the water solenoid valves.

Lock up and damage can be caused.

Fit water supply tap close to the unit to assist in routine servicing.

Before connecting the supply pipe flush it of any swarf or debris that may cause the float valve to

leak.

NOTE: In areas where water pipes freeze, provisions will be needed to drain the water piping to

prevent damage

External water

connection 1/2”



Dump Valve (Optional)

Dump valves, if required, may be supplied as an optional extra and field fitted. Installation should be

carried out in accordance with the instructions supplied with the valve. The dump valve should be

controlled so that water pump cannot operate when water tray (sump) is empty.

• To fit a dump valve a 40mm hole will be

required in the lowest section of the tank using

the optional sump dump well.

Note:- the overflow assembly is still required.

• Where a Dump Valve is to be fitted, the

solenoid MUST be installed in series on the unit

side of the water-isolating tap.

• Fit the black pressure tube between the dump

valve and the solenoid valve.

• The 24V solenoid will be supplied with an in-line

transformer for 240V connection.

• Connect the 240V solenoid transformer leads in

parallel with the pump terminations.

Or

Connect to a timed / delay independent circuit

supplied by the installer.

• The tank in the unit will only fill once power has

been applied to the solenoid valve transformer

via the pump or an alternate dump timing

circuit. The water pressure through the black

tube then closes the dump valve.

Drain

The combination drain/overflow pipe outlet must be

connected to a drainpipe with sufficient capacity to

take the discharge of water from the reservoir.

The pipe must connect to a suitable drain or gutter.

Drain must be lower than base of pad assembly.

Note: Refer to local regulations to ensure

discharge of drain / overflow water is

in accordance with statutory

requirements.



ROOF STANDS

INSTALLATION and ASSEMBLY INSTRUCTIONS FOR HCV ROOF STANDS

These roof stands have been designed to be assembled on site and come complete with all necessary items

to achieve a level mounting surface for the unit. When mounted either parallel to or across the roof pitch,

the stands will compensate for the following maximum roof pitches.

HCV 26 18° 25°

HCV 35 15° 22°

HCV 40 15° 22°

HCV 45 & 50 Special Roof Stands Required

It is recommended that waterproof timbers or similar be fitted to the roof under the stand legs to distribute

the unit weight evenly. Assemble roof stand frame as per diagram, attach corner legs and feet to suit

approximate roof pitch. Cross members incorporating twelve punched holes must be fitted to both ends of

the roof stand. The heater section end or discharge end can be identified by the cross member which is

387mm from an end cross member.

Place in correct position on roof and adjust level. Fix leg braces into position (ensure legs are at right

angles to frame) and tighten all bolts. Flat washers to be fitted under all bolt heads and nuts. Hole

spacing’s in the long and short leg combine to provide adjustment of height increments of 12mm. Finer

adjustment if necessary can be made by placing 1.6mm metal packing pieces under the feet of the stand.

Provision has been made for the leg braces to be fitted to side members in two positions. This makes

allowance for standard pitch and shallow pitch roofs.

If the full length of the legs is not required, the excess may be cut off at the top leaving 38mm above the

roof stand surface for locating purposes.

NOTE: On the HCV 12 roof stand it is necessary to cross the leg braces on the end. This is achieved by

fixing one brace to the inside surface of the leg and end cross member and the other as shown in the

diagram in accordance with statutory requirements.

COOLING SECTION

1. Check that unit is level.

2. Install float valve. Ball valve assembly is supplied to attached to a bracket which is fitted into the

corner of the base tray so that ball valve connection fits through hole in corner post. Water supply is

then connected via an isolating valve. Ensure that available water supply pressure is not less than 220

kPa (30psi). Set ball valve to maintain water level approximately 10-15 mm below overflow once

overflow has been correctly installed to height. Check water supply line for leaks.

3. Check and tighten mounting frame bolts (if used).

4. Once water overflow pipe is fitted and cut to correct height install bleed off tap. Set bleed off rate to

the following table by adjusting the tap located in the bleed off tube:

Bleed Off Rates

Model HCV 12 16 22 26 35 40 45 50 Water Quality

Time in Seconds 240 200 120 120 100 80 80 80 Melbourne 40-100mg/L

60 50 30 30 25 20 20 20 Hard 400 + mg/L

NOTE: Formation of salt deposits in pads indicate insufficient bleed off.

DUMP VALVES:

An additional optional dump valve system can be installed to activate to drain water tray deactivation of

water pump on shutdown or during heating cycle.

Installation of Dump Valve is not an alternative to bleed off.

Bleed of rates must be maintained at all times during cooling cycle.

5. Check and set water distribution by adjusting water restrictor screw. The correct setting is important

as follows:

Average flow rate per distributor outlet seconds per litre:

80 on HCV 12, HCV 16.

60 on HCV 22, HCV 26, HCV 35, HCV 40, HCV 45, HCV 50, HCV 60.

Discharge rate will vary with fluctuations in power supply, cleanliness of pump strainer and condition of

water distributing system. When adjusting water flow, avoid overflowing of pad or starving pads of

water. Excessive water may cause failure of fan and/or pump motors. Check water discharge is

vertical.

6. Tighten bearings.

7. Check blower wheel for direction (ie installed correctly).

8. Check motor and pulley alignment and check pulley mounting screws tight.

9. Check Vee belt tension

10. Check overload setting for blower motor.

11. Check motor speed and pump operation via selector switch. To eliminate possibility of water being

drawn into the blower, do not operate blower motor and pump with louvre pads removed.

COMMISSIONING


HEATING SECTION

1. Ensure gas pipe is free of condensates and deposits before connecting to heater.

2. Purge all air from the pipeline and check for leaks by using a soap solution or leak detector.

3. Ensure that motor and fan will turn freely by hand and are not fouled by foreign objects.

4. Check gas pressure before gas valve (Must be less than 3.5 kPa)

5. If a time clock is incorporated in the system set hours and day requirements to customer specification.

6. Set thermostat to temperature as requirements to customer specifications.

7. Turn on main line gas stock cock and leak test gas connections to unit.

8. Check pilot burner electrode gas is 3mm from the pilot’s gas hood and that the flame rod has not

become bent and short circuited to a burner or the unit frame.

9. Turn on gas cock in unit. Turn off test firing switch (if fitted), or set cock to pilot position.

10. Set remote switch to “Heat” and turn on main isolating switch in the H.C.V. The fan will start, leaving

air damper will run to closed position. On HCVR models return air damper will open cooling air dampers

will close. At the same time pilot burner/s will ignite and gas valve will be heard to click open. Should

pilot/s fail to ignite, turn off main or selector switch and wait five minutes. When pilot ignites, check

that flame is licking over the edge of the main burner adjacent. If not pilot flame may be adjusted by

the pilot regulator or by the small adjusting screw located under the round headed screw on the top of

gas valve with fibre washer has marking pilot adj,

11. Turn off unit, set room thermostat to a setting above the room temperature. Turn on test firing switch

or gas cock to main valve position. Switch unit to “Heat”. Main burner will ignite on high fire

automatically. Check operating inlet and manifold pressures against the specification plate.

Note: If correct pressure at the burner cannot be obtained by adjusting the main gas regulator in the

unit, check pressure at inlet of unit stop cock. If inlet pressure is less than minimum specified on the

label, either gas supply line to the unit is undersized and/or restricted or the meter outlet pressure is

too low.

Contact the local gas authority – DO NOT attempt to adjust main gas regulator where gas enters

premises or at meter unless authorised to do so.

WARNING: If pressure is lower than specified, unit could burn back and soot up burners.

Combustion Dampers: LPG & Towns Gas ensure that for manufactured gas (towns gas) the combustion

dampers located beneath the burner trays are fully closed.

For natural gas dampers are not fitted ex-factory.

For LPG generally leave dampers wide open, but they may be partially closed to stabilise flame if

required.

COMMISSIONING


TEMPERATURE CONTROL

Refer ADDENDUM for modulation operation. Based on standard Unit

HIGH LIMIT

If the high limit does trip the cause should be sought and rectified as this is not a normal operating

function. The high limit control also contains another switch which functions to allow the fan to run on or

restart when unit is turned “OFF” at the selector switch. This occurs to remove residual heat and to prevent

the high limits from locking out.

The fan switch should be set to start the fan at 60°C and cut it out at 32°C. Discharge dampers located at

the outlet of the heating section are controlled by a two position damper motor which is fitted and wired as

an integral part of the unit. The dampers closed position may be varied by adjusting the linkages. This is

done to provide the air quantity or temperature rise required for heating.

NOTE:

Temperature rise must be between 11°C and 33°C.

On “High Cool” and “High Vent” dampers must be in the fully open position. On “Heat” setting dampers

travel to provide design temperature rise against air change rate required. The dampers will travel to this

position for “Low Cool” and “Low Vent”

If temperature rise or air change rate is not specified, set dampers to provided 22°C temperature rise.

IMPORTANT: If heater will not operate after carrying out instructions as detailed above contact Aira Pty L

BLOWER AND DRIVE COMPONENTS

1. Blower motor: The ball bearings in all motors are pre-packed with grease and they require no further

attention for several years of normal operation. After this time the motor may be stripped down and

bearings washed out and repacked with standard bearing grease. (Shell Alvania N°2 or equivalent).

2. Blower bearings (Fan Wheel bearings): These bearings leave the factory lubricated with a special long

life grease and under normal conditions should not require attention for several years.

3. Belts: When installing and adjusting the belt or belts, loosen the motor platform adjusting bolts and

adjust until the belt can be easily deflected 12 – 20 mm. Correct belt tension and alignment is very

important as it cuts power consumption and prolongs the life of the belt and motor. When belts require

replacement the same grade of belt must be used ig: so not substitute ‘A’ section for “SPA” section.

COOLING SECTION

THIS SECTION DETERMINES THE LIFE SPAN OF THE COOLING SECTION OF YOUR H.C.V.

1. Turn off electric power supply.

2. Remove pad assemblies.

3. Check condition of Pads – use a hose to clean dirt off pads. Do not use excess water as this may make

holes in the pads. If pads are to be replaced obtain replacement pads from the manufacture.

Replacement pads are made to order.

4. If water supply has been disconnected or turned off, reconnect and turn on to fill water tray having

brushed out any dry material. If unit has been left full of water, this should be drained out and the

water try cleaned before refiling. DO NOT add any bio-cides to the water tray after filing. Check float

valve for correct water level and operation.

5. Check condition and tension of fan belt/s. Adjust and/or replace as necessary.

6. Check pump operation and that bleed-off is operating correctly and not blocked.

7. Refit pad frames and start up unit in accordance with operating instructions.

8. Cleaning: The filter pad frames in the HCV cooling section should be periodically, cleaned. At this time

the cooler cabinet should be inspected and cleaned. Filter pads should be periodically changed, the

frequency being determined by the rapidity with which dirt, alkali and other foreign matter

accumulates in the pads to the extent that cooling efficiency is impaired. The need for changing pads

caries with the locality. If in very good condition, pads may be washed to clean away dust etc, but if

pads appear aged or badly fouled, then replace. In localities where there is an excess of lime and

alkali, the reservoir pan should be cleaned out ever 60 days. If the water is all recirculated this clean

out must be done more frequently. This will also remove dirt which has been washed out of the filter

pads.

9. LEGIONNAIRES DISEASE: Evaporative air conditioners have not been implicated in any outbreak of

Legionnaires disease, although Legionella bacteria have been found in such systems. The water

temperature in the evaporative air cooler section is normally at about 18°C at which temperature the

Legionella bacteria (if present) will remain dormant and cannot multiply.

The following maintenance schedule is required to be followed in order to comply with the New South

Wales Public Health Act 1991 section 46:-

a. Sumps are to be drained and cleaned at three monthly intervals or more frequently if necessary.

b. Wetted pads are to be drained and cleaned at three monthly intervals or more frequently if

necessary.

c. Water strainers are to be cleaned at three monthly intervals or more frequently if necessary.

d. If any air filter is fitted, it is to be cleaned or replaced when necessary.

UNIT SERVICE


HEATING SECTION

The frequency with which maintenance must be carried out will depend upon installation conditions and

heater usage. It is recommended that an annual inspection of flue tubes and burners be carried out by a

qualified serviceman. As soot or dirt will prevent proper combustion, the serviceman should look for such

things as evidence of blocked burner ports, heavy ash or soot deposits or irregular flame shape. Any of

these signs can be a warning of improper combustion, lowered efficiency and decreased reliability:-

Clean and Service

Should a full “clean out service” be necessary, the procedure is as follows:

1. Shut down appliance as per procedure on data plate and switch off power supply at isolator.

2. Remove front lower access panel to give clear access to burner chamber.

3. Remove radiation shield/s from under burner bed/s (when fitted).

4. Remove the pilot/s and burner bars.

5. Remove flue pipe from unit.

6. Remove draft diverter as follows:

a) Remove front upper access panel.

b) Remove sheet metal screws at rear of draft diverter and lift about 50mm, slide slightly towards the

rear to remove from offset at front.

7. Lift internal baffle assemblies from flue tubes.

8. Clean baffle and inner surface of flue tubes thoroughly. A 38 or 44mm diameter wire brush with a long

handle is recommended.

9. Remove dirt from bottom tray.

Remove Pilot Assembly and Burner Bars

1. Uncouple pilot gas pipe from the pilot burner/s.

2. Pilot assembly can be removed by two 4mm screws

3. Remove the burner tube to which the pilot is attached by sliding the burner bar sufficiently towards the

front of the heater to allow the round end of the burner to disengage – age from the manifold plate.

Lower the end of the burner and remove from rear location plate.

Remove Main Burner Bars

Remove all burners as describe above. Lightly brush away any deposits from burners and inspect for

damaged or blocked ports.
