Important Installation Points

The unit must be installed to comply with national regulations and/or codes of practice. A qualified electrician must carry this out. Do not locate the cabinet where the ambient temperature around the unit could exceed 40 ºF( 35º C); or fall below 95º F( 5º C) e.g., an unventilated roof mounted enclosure – see minimum space / ventilation requirements pages 4 & 5. Make sure condensate line(s) have adequate slope (min 8% or 1in per foot) for condensate drainage and use. Provide adequate support to prevent sags developing in flexible steam lines, which can fill with water and create a "trap". Do not locate drain open air gap directly within the ventilated void area.

Important Electrical Connection Items Before commissioning the unit, check that all electrical (power and control) connections - including those at the terminals and contactor are tight. Check that the transformer primary winding connection is made and at the supply voltage on Vapac terminals A1 & A2. The Vapac transformer must not be used to power other equipment. To reduce the EMC aspects see recommendations on page 8. It is important to note that the control signal input to terminal 5 is connected to ground at the Vapac control PCB.

NB: Care should be taken if the controller output is also referenced to earth, as incorrect connection will lead to damage to the controller and or the Vapac control PCB.

Important Maintenance Items Only a competent person should carry out maintenance. The boiler contains hot water, and must be drained before any maintenance is carried out on the steam section. This should be done prior to isolating the power, and removing the access panel. ESD SENSITIVE DEVICES USED ON PCB. ENSURE ANTI-STATIC PRECAUTIONS ARE TAKEN WHEN REMOVING OR REPLACING PCB’S.

1. Content of the Vapavoid box 1.1. Vapavoid cabinet with 2 duct connectors (supply/return), 4 feet of silicone hose, 1 Tee for proper

drain lines installation and 1 flexible hose for water supply. 1.2. Modulating wall humidity controller 61-HC-107 or on/off controller 61-HC-108 depending on

Vapavoid chosen. 1.3. LED Status indication panel with 20ft of wiring, 61-KIT-0015.

2. Do’s and Don’ts of the installation process DO’S Do install the top of the cabinet level in both directions as the unit contains a drain tray which must

have the correct slope inside. Do install the cabinet with a clear access to the lower panels of the unit whenever required and

without requiring the removal of equipment, furniture or other. If possible install cabinet clear of ceiling tile tee bar or support grid.

Do ensure adequate service access below the unit (min 39”). Do use the marking on the side of the carton as a template to mark the mounting hole positions. Do use three 5/16” stud drop rods or bolts each side of unit (six fixing points) to support the unit level

and flat.

Don’ts

Don’t mount the unit close to sources of strong electro-magnetic emissions e.g. variable speed lift motor drives, kVa transformers etc.

Don’t mount the unit in an unventilated enclosure. Don’t mount in a position where access to the unit will not be possible when all pipe work, vent ducts,

and electrical services are installed. Don’t mount the unit over light fixtures, fire sensors or other equipment connected onto the ceiling

grid or ceiling tiles which would prevent access to the cabinet underside. Don’t mount the unit in an area which will be hosed down. Don’t install the unit where the ambient temperature can exceed 95°F; or fall below 40°F. Don’t mount the unit inside a cold-room or other place where temperature and humidity conditions

can cause condensation on electrical components. Don’t mount the unit where the clicking of components, boiling action and water flow in a pipe would

be unacceptable or anywhere where the specified unit noise rating is not to be exceeded. Don’t mount the unit above a desk, person or anything that could be damaged if water would fall from

the unit during maintenance.

6. Plumbing Considerations 6.1. General

Do’s Do install a stop-valve/shut-off valve and a strainer close

to the unit. Do provide a water supply with sufficient pressure and

pipe size to ensure an adequate flow rate to all units connected to the system.

Do use the flexible hose connection with nylon nut provided.

Do ensure metal supply water pipework is grounded electrically close to the unit (a ground/earth stud is positioned on the underside of the cabinet).

Don'ts Don’t use a wrench or other tool to tighten the water

supply connection - the nylon nut and rubber washer provided, should only require tightening by hand. If water leak occurs, undo the nut to wipe the washer clean and re-seat it.

Don’t use hot water to feed the Vapavoid humidifier.

6.2. Cold water supply quality The Vapanet range of electrode steam humidifiers are capable of operating with a range of potable water quality. The water supply should be within the following limits:

Hardness 50 – 500 ppm Conductivity 80 – 1000 µS* PH 7.3 – 8.0 Silica 0 Water Pressure 22-116 psig (1.5 - 8 bar) Chlorine <170 ppm

The water supplied to the Vapavoid should not be heated.

6.2.1. Water Fill rate The max supply rate of water going in the system is : Water Supply rates 0.07 USGPM (0.25 l/min)

All Vapavoid

6.3. Drain connections

Do's Do ensure metal drain and supply water pipework is grounded electrically close to the unit (a ground/earth stud is positioned on the underside of the cabinet).

Do’s Do use copper or plastic pipe rated for 212 Deg F. (110

oC). Do arrange to discharge drain water from the unit into a

trapped and vented drain at a position where flash steam rising from the drain line vent will not pose a problem for the Vapac or other equipment.

Do provide adequate fall for the drain pipe work to allow free flow of water drained from each unit. Do ensure drain line pipe size will accommodate water

being drained at the same time from all the Vapac units which are connected to it.

Do ensure drain line has a min fall of 5° (1 in vertical for every 12 in horizontal or 8% slope) and sized adequately to take all units connected into it at full pump flow rate. Each LFE unit has two pumps, one from drain pan and the other from cylinder. These both have the same flow rate as indicated in section 6.3.1 below.

Do run both condensate outlets from unit independently until both pipes have dropped 4” before tee together as shown below.

6.3.1. Drain rate

Drain capacity and drain tray pump = max 3.22 gpm (12.2 l/min)

6.3.2. Cylinder and drain pan outlet The unit has 2 drain outlets serving the 1. cylinder and 2.the internal drain pan. Both outlets need to be piped separately to a T using silicone hose provided. The outlets can be joined together using the supplied plastic T only when the two drain lines are min 4in from the starting point to ensure water from one drain pump is not fed into the other. See schematic below for two options available for piping the drain. The drain line must be slopped down a min of 5 Deg.

8

6.3.3. Drain Tray overflow

The unit is fitted with a drain tray overflow pipe which is not pumped mechanically, this is a pipe located at the top of the drain tray. It is recommended to pipe this outlet to drain as this is the last resort if the drain pumps and fail safe shut off fails. If none of these devices function properly, the water will overflow to drain via this outlet. This is to prevent damage to drop ceiling area or any equipment or furniture located below.

7. Electrical Connections

7.1. Wiring The unit is designed for use with various supply voltages between 115 & 347 Volts single phase. The voltage that should be applied to the unit should be the one on your spec label. The wiring to the Vapac unit should be done by a qualified electrician. The external over current protection and wiring should comply with the appropriate Regulations and Codes of Practice.

A fused disconnect / isolator or MCB should be used to disconnect the supply from all electrodes simultaneously.

This must be sized to suit the total maximum phase/line current of the unit and should be located adjacent to the Vapac cabinet or within easy reach and readily accessible.

NB terminals are situated in the electrical section adjacent to the On/Off/Drain switch.

7.2. Important E.M.C. Considerations Use a dedicated, earthed metal conduit for both the control signal cable and the security circuit cables along their entire length - they may share the same conduit where practicable. The earth must be made by "metal-to-metal" contact and should be a good RF (Radio Frequency) earth. Control Cable / Security Circuit Screening Arrangement

The control and security circuit connections should be run in screened cable with the screen grounded within the Vapavoid (onto the electrical section back panel). The screen should be maintained as close as possible to the cable ends and any tail between the screen and the earth point must be kept short (50 mm maximum).

7.3. Power Supply Connection The unit requires the following connections:

Single Phase Units: - Live +Neutral:

Supply L1(by others) to Terminal A1 and Neutral to A2

- Supply L1(by others) to Terminal A1 Supply L2(by others) to Terminal A2.

In addition all units require a protective Earth (PE) to be connected to the main earth terminal.

7.4. Transformer electrical Transformer supply 115/208/230/277 or 347 volts 60Hz 24 V a.c. Control Circuit:

3.15 A 20 mm (T – Time Lag) fuse (Pt. No. 60-108-0096) mounted on VAPANET PCB (Pt. No 60-115-0656-1).

Transformer Primary Circuit There is one control fuse which protects the transformer primary circuit F1 2.0A (slow blow) (Pt. No. 60-108-0095) mounted in fuse-terminal holder on the main terminal rail; this fuse protects transformer primary supply the transformer secondary feeds the Fan and the 24 volts control to the PCB board. The transformer has the following auto winding tapings for the fan supply 170 and 208 Volts.

7.5. Unit Voltage Selection Selection of the voltage and control signals is factory set using resistors fitted to UCP3 NB Verify your spec label for the voltage selected on your unit.

8.4.2. Proportional Control The VAPANET Electrode Boiler (LFE) models can all be operated by either a potentiometric signal or by one of the following standard proprietary DC analogue signals: 0 - 5 Vdc, 0-10 Vdc and 4-20 mA. Response of the unit is from 20 -100%. NB. - The control signal is connected to ground at the PCB – if

the controller output is referenced to ground, then the “leg” which is ground must be the one linked to terminal 5.

- If 4-20 mA (suffix -20) is ordered, check that Jumper J1 is fitted on the main board and should be across J1.

- Use of the 24V supply of the VAPANET unit to power other items of equipment will invalidate the Vapac warranty.

- In contrast to other Vapac units, the Vapavoid does not require a jumper on 5-7.

9. Drain operation As standard the unit is set for “Economy mode”, which has a reduced automatic drain rate, which will reduce the amount of hot water (and therefore energy) which is expelled to drain. If the supply water is very conductive, or if the unit experiences operational difficulties it may be necessary to introduce additional drain cycles – this can be achieved by adding a jumper from DI 3 to DI (Com.) as shown on the following.

11. Start-Up / Operation

11.1. Start-up check list

a) Water supply and Drain Connections: These should be connected as indicated under Plumbing and in accordance with the relevant local regulations. An isolation valve should be adjacent to the unit. The connecting metal plumbing must be grounded close to the unit.

b) Power supply: Wiring to the Vapanet unit should be by a qualified electrician and comply with the relevant regulations using appropriately sized cable and cable glands, with disconnect and fuses to suit the maximum fuse rating of the unit at the supply Voltage. The disconnect / fuses should be adjacent to the unit or within easy reach and readily accessible.

c) Control Connections: Ensure the control signal and security circuit are correctly connected according to the relevant instructions/diagrams.

d) VAPANET 24v Control Circuit Transformer: The standard 24V transformer used in the units has primary winding for 115; 208; 230; 277 & 347V 60Hz connection derived from the local electrical supply.

e) The maximum output & kW rating of the unit is determined by a Current Set Plug. It is therefore possible to down rate units to any output, down to approximately 50% of the full rated output. (Contact Vapac for further details)

f) Unit Configuration Plug (U.C.P.) sets the maximum current level for the unit. It is fitted directly onto the control P.C.B.

11.2. Start-Up Instructions

First check: a) That the transformer connection matches supply

Voltage. b) That the security circuit is closed for unit

operation.

Close the electrical access panel.

Turn on the water supply to the unit. Close disconnect/circuit breaker feeding supply to the unit. Turn off the On/Off switch.

11.3. Commissioning/Start-Up Once the Set-Up procedure has been completed, the unit is available to operate according to the requirements of the control signal. When starting with an empty cylinder, the VAPANET program switches in the relay and feeds water in until the water reaches the electrodes, and current starts to flow. Thereafter the VAPANET system will continuously monitor and control the conductivity by adjusting the amount of water drained and fed into the cylinder. With no demand the LFE unit’s user LED’s will be off. When the demand increases and the unit is switched on the user LED’s will flash green/amber at a rate depending on the demand input and the actual current drawn. The actual run current is monitored and until the actual current has two feeds above 95 % the LED will flash green/amber when the current is above 95% for two consecutive feeds the LED will flash red.

11.4. Features of the Vapanet control system The VAPANET system of control is designed to adjust the function to keep the unit operating in the face of changing water quality in the cylinder and changing electrode condition even if, in an adverse operational circumstance, this results in some reduction in output while the situation exists.

Foaming protection In particular, the VAPANET is designed to prevent the onset of foaming and to introduce corrective drainage to keep the unit working.

Automatic switch-off The VAPANET PCB will stop operating in response to extreme fault conditions identified as: -Drain Fault STOP (no drain function). -Feed Fault STOP (water not reaching cylinder). In each case, the display will show the STOP condition and a Help Message, the User LED’s on the fascia will indicate the condition see table on page 20. The STOP condition of a VAPANET PCB will be cleared by switching the unit off and on. THIS ACTION SHOULD ONLY BE TAKEN ONCE THE CAUSE OF THE PROBLEM HAS BEEN ASCERTAINED AND RECTIFIED.

12. Servicing - Maintenance

The water hardness and the humidity demand at site will determine the effective life of a steam cylinder. Units located in areas with naturally soft waters will experience the longer cylinder life, possibly upwards of 12 months in calendar terms. With hard waters, a more frequent cylinder exchange must be expected and cylinder exchange 2 or 3 times a year can be experienced. The normal scaling up of the Vapac steam cylinder is outside the Vapac warranty.

62-LIT-0010 2011/07/26

12.1. Procedure for Cylinder Exchange.

A) Draining the unit 1. With the power connected to the unit, manually drain the

cylinder, by depressing (and holding) the Run/Off/Drain Switch to the momentary drain position.

2. Remove the steam section access panel. 3. Drain water from the drain pan area via side plug catching

any water contained in the drain tray into a container as plug is removed or manually activate the drain pan float switch by toggling the float with your hand on the inside of the pan so as to activate the drain pan drain pump.

4. Disconnect the Vapac from the incoming electrical supply by means of the external isolator (disconnect switch). This should be “locked off” to prevent accidental operation. B) Disconnecting all wiring

5. Remove the plug connection for the float switches and drain tray condensate pump.

6. Remove the electrode connections. 7. Disconnect the drain pump.

C) Removing steam distributor and trap 8. Remove the steam distribution assembly and trap by lifting

it clear of the cylinder steam outlet. 9. Note it may be necessary to rotate it as it is raised to get it

high enough to clear the boss.

D) Removing the drain pan 10. Standing so as to face the drain cylinder, slide the drain

pan assembly to the right, until the tray is clear of the mounting support.

11. Lower the left end of the tray (cylinder side) below the lip of the access panel, and then slide to the left to clear the right hand mounting support. When it is clear lower the drain tray clear of the unit. E) Remove the cylinder as follows:-

12. Slide the drain pump and feed adaptor away from the cylinder, until they are clear of the cylinder feed/drain boss, and the pump body is clear of the pump mounting plate. Take care to note the orientation of the pump on the mounting plate, as it will fit on more than one face of the pump body.

13. Remove the cylinder mounting screws and remove the cylinder. Note: There will be residual water in the cylinder and care should be taken not to spill this as it could be hot or discolored and could burn or stain.

12.2. Maintenance Interval As the operation of the Vapac is entirely automatic, it normally requires no attention on a day-to-day basis. General cleaning and maintenance of the component parts of the Vapac are recommended at intervals of about one year, but this is largely dependent upon the frequency of its use and the quality of the water supply. Where the Vapac is part of an air-conditioning system being serviced regularly, the Vapac should be inspected at the same time.

12.3. Feed Valve with Strainer The nylon bodied solenoid valve incorporates a small nylon strainer which is a push fit in the 3/4" inlet of the valve. With a new plumbing installation, residual loose solid material in the pipework could partially block the strainer after start-up. If for this or any other reason a restriction of the water flow is suspected (outside of supply pressure considerations), it would be possible to clean the strainer as follows: - Turn off the water supply to the Unit. - Undo the nylon nut connecting the flexible connection to the valve inlet. - The strainer can be removed using ‘long-nosed’ pliers to grip the centre flange provided on the strainer for this purpose. - Remove the strainer. - Wash and replace it. - Reconnect and turn on water supply. - Reconnect electrical supply to allow unit to operate. Note: Always replace the strainer after cleaning as it is required to prevent material lodging in the valve seat or blocking the small flow control restrictor which is fitted in the valve.

12.4. Drain Pump The pump should be inspected and cleaned regularly. It is recommended that this is done at each cylinder exchange especially in hard water areas. Failure to keep the pump clear and operational will result in reduced cylinder life. To remove the pump for maintenance purposes proceed as follows:

Depress and hold the manual drain switch to empty the cylinder. The pump sound changes distinctly when the cylinder is empty. When this occurs release the switch.

Disconnect unit electrical supply and follow the steam section removal instructions. Once the steam section has been removed, the pump can be removed.

Ease the pump body away from the cylinder, sliding it fully off its base plate and release the connecting tube.. As the pump inlet is withdrawn from its ‘O’ ring connection, some hot water may be released, so care should be taken.

To dismantle and re-assemble pump refer to the diagram below.

In operation the stainless steel shaft remains stationary while the rotor and impeller rotate on it. Remove all scale build-up on the shaft so that the impeller can rotate freely.

Ensure that the ‘O’ ring seal is correctly positioned when fitting the inlet housing to the main pump body. When re-assembling, make sure the brass spinner is replaced on the shaft in front of the impeller. A smear of multipurpose grease should be applied to the ‘O’ ring so that the impeller housing can be rotated into position without distorting the ‘O’ ring underneath it and so maintain the water seal.

The steam section should be refitted by following the removal instructions in reverse order, reversing all instructions.

12.5. Steam and Condensate Hoses The hoses used with and in the Vapac unit should be inspected at the normal service visits as part of normal maintenance. At the first signs of deterioration, a hose should be removed and replaced.

12.6. Steam cylinder models Different cylinder models are available for the humidifier to adapt to extreme water conditions. The standard cylinder included with each Vapavoid is the Low conductivity cylinder and will work in 80% of application. Do replace by another type of cylinder when recommended by technical support personnel.

Cylinder Models: Low Conductivity

Medium Conductivity

12.7. Other notes on maintenance: Maintenance should only be carried out by a qualified

technician. The steam cylinder should be drained prior to carrying out

any maintenance in the steam section – This must be done prior to isolating the electrical supply, i.e. before removing the front access panel.

The unit should be isolated from the electrical supply before any cover or access panel is removed.

14.2.1. Introduction The humidistat is used to control the humidification cycle by monitoring the humidity in the room and comparing it to a set-point selected on the display. The humidity controller sends a 0-10vdc signal to the humidifier via the terminal strip.

14.2.2. Connecting the controller Refer to section 8.4.2 for detail on the wiring.

14.3. Vapac on/off controller with display: 61-HC-108

14.3.1. Introduction

The humidistat is used to control the humidification cycle by monitoring the humidity in the room and comparing it to a set-point selected on the display. The humidity controller controls the unit via open or close signal.

14.3.2. Connecting the controller Refer to section 8.4.1 for detail on the wiring.


14.4. Digital Remote display box: 61-HH-03

14.4.1. Introduction The 61-HH-03 consists of a Vapac Alpha-Numeric Display PCB (EW Part No. 60-115-0631-LFE-M1 fitted into a plastic enclosure with a keypad label and pre-wired flying lead for connection to a Vapac “Vapavoid” unit. It is used to enable a Service Engineer to interrogate the unit; to set certain operating parameters and to perform some functional tests. The display runs a special “build” of Vapac electrode boiler display software (which is in “English” only, this is because there is insufficient memory space to hold the translation code) which will interface with any Vapac electrode steam humidifier controller software (including the Vapavoid ranges)

14.4.2. Connecting the display The flying lead can either be plugged into the external, panel mounted, 4-way connector adjacent to the factory fitted cable glands (for Power & Control cable connections) or plugged into the bottom connection of the pluggable terminals 94-97 (please note that the top connection [shielded by a plastic cover] should not be used, as the connections will be reversed - connecting the displays power supply [24 Vac] directly across the “network” components).
