* With some Brivis Heater models a transition fitting will be required to increase the pop size from the heater to match the inlet pop size of the Add-On Cooling indoor coil. If an installation kit thermistor collar assembly has been used then its diameter should also be increased to match the indoor coil inlet pop diameter. DO NOT REDUCE POP SIZE ON INDOOR COIL The system must be fitted with a correctly sized return air grille that includes a filter, to ensure the indoor evaporator coil does not become blocked with airborne dust and lint. The filter should be easily accessible for regular cleaning. (Refer to the Brivis Heating Installer Manual for minimum recommended return air grille size). If the system uses high-level outlets (e.g. ceiling diffusers), then the Return Air inlet must be at a low level. The Brivis Performance Guarantee may not be valid in ceiling systems with a high level Return Air. Ensure adequate ductwork and fittings sizing, particularly on zoned systems. Where bends are required in ductwork, these must be smooth large radius bends, NOT tight!! Always use minimum R1 insulated ductwork with in-ceiling systems, with all fittings insulated. Care should be taken to ensure minimized external static pressure (resistance) against airflow. Ductwork must be sized to handle the Heater’s total cooling airflow output through the system on either whole home or zoned basis. RECOMMENDED INDOOR/OUTDOOR MATCHING CHART

GENERAL Read all instructions before proceeding with the installation and start up. Note: This instruction applies to R22 charged units ONLY. This equipment must be installed in accordance with all relevant authority requirements. SAFETY CONSIDERATIONS The unit is designed to provide safe and reliable service when operating within design specifications. To avoid injury to personnel and damage to equipment or property when operating the equipment, the following safe practices should be observed as a minimum. • Check the unit weight (see Outdoor Unit Specifications on page 10) to be sure the lifting equipment is adequate. • Disconnect power to the unit before working on it. • Do not remove access panels or doors until fans have completely stopped. • Do not enter a fan cabinet while the fan is running. Isolate the power first. • Protect materials when welding or flame cutting. Use suitable cloth to contain sparks. Have a fire extinguisher at hand and

ready for immediate use.


PRE-INSTALLATION Remove packaging from unit and any protective foam packing from coils and pipes. Check items received against packing list. Examine unit for damage, which may have occurred in transit. Indoor Units are shipped with a holding charge of dry nitrogen. Check to confirm the holding charge. The Outdoor Units come pre-charged with R22. Notify the manufacturer’s sales representative of any damage. INSTALLATION REQUIREMENTS (OUTDOOR UNIT) Location: The Outdoor Unit must be installed in an area that is well ventilated. Ensure that the minimum clearances outlined on the Outdoor Unit Dimensional drawings (page 10) are maintained, so as to provide adequate service access and proper cooling airflow. Avoid positioning the Outdoor Unit near any reverberating structures such as doors and windows and ensure that there is sufficient distance between it and any adjacent neighbouring property so that “operation noise” emitted from the unit does not exceed the noise (dBA) guidelines as set down by local or state legislation or regulatory bodies. Mounting at ground level: The Outdoor Unit must be mounted on a solid, level foundation. Level and bolt the unit to the foundation, ensuring there is an insulating membrane such as rubber “waffle pad” between the unit feet and the foundation. Mounting on the roof: Ensure that the weight of the Outdoor Unit is not excessive for the design of the roof structure. The unit must be mounted onto either a suitably designed steel frame, ensuring that there is an insulating membrane such as rubber “waffle pad” between the roof structure and the frame for vibration elimination, or mounted onto red gum timber blocks again ensuring that “waffle pad” or similar is fitted between the roof structure and the timber to eliminate vibration. It is not permitted to install timber bearers in the tray section of a steel deck roof as support for the Outdoor Unit as the flow of water in the tray is impeded. The timber should be installed on the ridges of the steel roof sheets to ensure proper roof drainage. Both the metal frame or timber supports must be of sufficient size and length to prevent the Outdoor Unit tipping over in high winds. Electrical Power Supply A qualified Electrician must carry out the electrical installation. The Outdoor Unit must be wired directly from the main switchboard in accordance with Electrical Regulations and the unit’s wiring diagram. An external isolating switch must be installed adjacent to the Outdoor Unit also in accordance with Electrical Regulations. Check SAA Wiring Rules for “Protection” sizing and cable sizes. Short circuit protection for the unit must be supplied at the main switchboard using either a d-curve* circuit breaker (or equivalent), or HRC fuse. Rewireable type fuses must not be used. See Outdoor Unit Specification Sheet (page 9) for electrical information. * d-curve circuit breaker – a circuit breaker designed to provide protection for circuits with high in-rush currents, eg. motor start. INSTALLATION REQUIREMENTS (INDOOR UNIT) Location: Choose a location that is suitable for refrigeration piping and condensate drainage and so that adequate provision is made for service access. The Indoor unit is not weatherproof and should be installed so that there is no chance of direct sunlight or water/moisture coming into contact with the outer casing. Where the unit is installed in the roof or ceiling space it must be mounted on a working platform ensuring that the building structure is capable of supporting the unit’s weight. The Indoor Unit must be installed downstream of the Heater’s main Supply Air Outlet and located as far away from the heater as possible, but always before the first branch-take-off (B.T.O.) fitting. If the Heater has a remote thermistor installed in the supply air ductwork, the evaporator coil should be positioned downstream of the thermistor. If the evaporator coil is positioned before the thermistor, it will adversely affect the heater’s performance. Never put the Indoor Unit in the Return Air part of the duct system, this would result in condensation forming in the Heater, causing corrosion and damage to vital components. Ensure that a minimum of 1 metre or 2½ times the duct diameter (whichever is greater) of straight ductwork is installed immediately downstream of the Indoor Unit before any divergence or branch-take-offs occur. Failure to do this will void the warranty.

Condensate Drain: The Indoor Unit incorporates an evaporator drip tray and is supplied with a 20mm Female Pressure Pipe drain spigot, which is to be connected to the supplied "V" trap. Always install the “V” trap as close to the unit as possible. Fill the "V" trap with water during installation before starting unit, to prevent air movement through the drainpipe. It is imperative that the drain trap contains water at all times. Adjust the level of the fan coil unit to ensure that the condensate drains from the evaporator drip tray (approx 10 - 15mm incline from back to front).

A non-flexible drainpipe should then be installed for condensate run-off. This drainpipe is to have a continuous downward grade away from the unit, not less than 1:50. When the Indoor Unit is installed in a roof or ceiling space, an additional Safety Drain Tray (not supplied) must also be installed under the Indoor Unit. This Safety Tray must also be separately drained and the drain arranged to terminate in a position where the end user could see if water was dripping from the outlet. Please instruct the end user to call Brivis Service should they notice water dripping from the Safety Tray drain outlet. (see diagram on next page) Minimum Service Clearances: For servicing, a minimum clearance of 600mm must be provided in front of the access panel side of the unit for its entire length. Where installed on a platform in the roof space, the platform should also extend 600mm out in front of the access panel side of the unit for its entire length. A 600mm wide platform is required to connect between the indoor unit and the access opening or the ducted heating unit for the purpose of access and adequate lighting needs to be installed. Duct work should not be installed across the platform preventing safe access.


TYPICAL INDOOR UNIT INSTALLATION

The manufacturer reserves the right to discontinue or change specifications or designs at any time without notice and without incurring obligations. Page. 5


REFRIGERANT PIPING Piping Design Pipework must be installed in a manner which prevents drainage of liquid into the compressor and ensures adequate oil return. Pipes should be run as directly as possible between indoor and outdoor units. Horizontal Pipes Any buried pipes should be insulated and located in a plastic duct, complete with a vapour seal. The buried distance must not exceed 5 metres and a liquid line solenoid valve must be located adjacent to the indoor unit. The solenoid valve must be interlocked with the compressor. Vertical Pipes The height difference between indoor and outdoor units must not exceed 10 metres. If the outdoor unit is located more than 6 metres above the indoor unit, a liquid line solenoid valve must be located adjacent to the indoor unit to protect against refrigerant migration. The solenoid valve must be interlocked with the compressor. PIPING & CHARGING Warning: Both indoor and outdoor units come delivered under positive pressure. The outdoor unit is charged with sufficient refrigerant R22 to satisfy a connecting pipe run of 15m actual length. The indoor unit is pressurised with approx. 700kPaG (100 psi.) dry nitrogen. Connecting pipe blanking plates must not be removed until the installer is sure the plates are not under positive pressure. Read all piping notes below before starting installation. General The following good piping practices should be adhered to during installation: • A 3” one-way filter drier must always be installed, to contain particles and absorb any moisture. (Depending on the

unit’s date of manufacture, this filter/drier has been supplied by Brivis, either as a separate component or as an integral part of the Outdoor Condensing Unit. Where the filter/drier has been supplied as a separate component it is the installers responsibility to ensure that it is correctly installed on the liquid line before commissioning the system).

• Use new, clean and sealed refrigeration grade pipe. • Keep pipe ends sealed, both before and during installation, to avoid entry of moisture. • Purge pipes with dry nitrogen during brazing operations, to limit scale build up. • Suspend pipes with hangers or straps and seal openings around pipe penetrations with flexible material. Consider pipe

expansion and leave space between pipes and adjacent structures. • Use a brazing shield where required. • When brazing in the vicinity of valves likely to be affected by heat, they should be lagged with a wet cloth. • It is generally necessary to insulate the suction pipe only. However, it will be necessary to insulate the liquid line pipe as

well, where it is exposed to direct sunlight or if located in hot surroundings such as ceiling void, or buried underground. • Insulation should be nitrile rubber, 13mm thick for pipes up to and including 20mm diameter and 19mm thick for pipes

above 20mm in diameter. Indoor Unit • Check the unit pressure is still at 700kPa approx. with a suitable pressure gauge, connected to the indoor coil Schrader. If

pressure has been lost, proceed to check for a leak. • Remove the nitrogen holding charge by connecting a charging line with Schrader valve depressor. • Sweat off the liquid & suction pipe blanking plates & proceed to pipe up in line with general recommendations above. Outdoor Unit • Locate the suction & liquid pipe service valves in the compressor compartment by removing the service access panel. • Check that the service valves are tightly wound all the way in (fully front seated). • Wrap each valve in turn with a wet cloth prior to sweating off its associated blanking plate. • Braze in the interconnecting liquid and suction pipes from the indoor unit. • Pressurise the indoor unit & pipework again with dry nitrogen and check for any brazed joint leaks. Repair as necessary but

ensure the system under repair is not under pressure prior to brazing. • With the indoor unit pressure again released, evacuate to a vacuum pressure of 100 microns minimum. • Disconnect the vacuum pump whilst retaining the system vacuum. • Wind open the liquid line valve fully and then the suction line valve (fully back seated). • With all electricals correctly installed, the unit is now ready to be commissioned. Start the system in cool mode and allow it

to stabilise before checking liquid line subcooling (approx 6-10K) and compressor suction superheat (approx 5-8K). Refer to Start up and Commissioning procedures attached.

Refrigerant Charging As stated previously, the system is precharged for an installed pipe length of 10m actual length. For pipe lengths greater than 10m it will be necessary to add charge to the system. This is done by starting the unit and using it to draw refrigerant (gas only) through the compressor suction pipe Schrader valve, also located in the compressor compartment. Refer to the Piping data & Recommendations table over page for an estimate of the amount of refrigerant to be added, but be sure to check the system superheat and subcooling as explained in the section on Start up & commissioning. Check superheat and subcooling during cooling operation.

THERMOSTAT CONTROL WIRING • 24 Volt control wiring is required to be installed between the Outdoor Unit and the Heater / thermostat in accordance with

the wiring instructions supplied with the Brivis Network 506 Module (for Brivis MPS & Auto EMS model heaters) or the wiring instructions on page 21 of this manual (for current Brivis Classic model heaters). For older existing Brivis Heater models contact Brivis for advice. For any other make of heater (Non- Brivis) contact the Heater’s manufacturer.

• The thermostat should be located as per the installation instructions supplied with the Heater. • Minimum control circuit wire size is 1.00mm with a maximum of 1.50mm Note: There is no time delay built into the Outdoor Condensing Unit to prevent compressor short cycling on rapid calls from the thermostat for cooling. • Network controls on Brivis MPS/Auto EMS Heaters are designed to prevent short cycling of the compressor and the Brivis

Programmable thermostat, which must be used on Brivis Classic Heaters for cooling is also designed to provide this protection.

When adding this ICE Series Add-On Cooling equipment to a system where another brand of heater is installed, it is the installer’s responsibility to ensure that some form of timer delay or other protection is installed to prevent the compressor short cycling. Failure to do so will void the warranty. START UP & COMMISSIONING Ensure that a Return Air Filter is fitted prior to fan start up (filters are not supplied with the unit as standard). Fill out the system details as noted under PRELIMINARY SYSTEM INFORMATION and check all items as noted under PRE START-UP on the Commissioning Sheet provided (page 23). • Switch the unit on in cooling mode with the thermostat set to minimum temperature set point. • Check suction and liquid pressures. • Add/remove refrigerant as required to achieve the correct design charge. Care must be taken to charge the system

correctly. Undercharge will result in lack of capacity and unit will lock out on LP switch. Overcharge will result in high head pressures whilst unit is operating.

• Measure the compressor suction pressure and convert to a compressor saturated suction temperature (CSST) using R22 refrigerant pressure/temperature table.

• Measure the suction line temperature (SLT) approximately 100 mm before the compressor. • Calculate the superheat (SH) = SLT – CSST. • Measure the compressor discharge pressure and convert to a condensing temperature (CT) using R22 refrigerant pressure

/ temperature table. • Measure the liquid line temperature (LLT) between the outdoor coil and indoor unit throttling device in cooling mode. • Calculate the subcooling (SC) = CT – LLT. • Measure the outdoor ambient air temperature. • Measure the indoor return and supply air dry bulb and wet bulb temperatures, both before and after the indoor coil. • Measure the indoor air quantity ensuring it falls within the Indoor Coil’s limits (see Indoor Unit Specification on page 11). • Adjust the heaters fan speed to suit the static pressure and air quantity requirements. • Allow system pressure to stabilise for a minimum of 20 minutes. • Measure and record all operating pressures, motor currents and temperatures as noted under OPERATION

CHARACTERISTICS on the Commissioning Sheet provided (page 23). • Please detach pages 23 (Commissioning Sheet) and 27 (Privacy Notification Statement) from this manual and leave them

with the customer. Please ask the customer to fill in the CUSTOMER DETAILS section and to return the completed Commissioning Sheet* to Brivis in the pre-paid envelope provided.

• WARRANTY WILL ONLY BE VALID UPON RECEIPT OF THE COMPLETED FORM TO BRIVIS.


SEQUENCE OF OPERATION Check correct sequence of operation, then proceed to instruct customer on correct thermostat operation for refrigerative cooling. Refer to the thermostat operating instructions in the Owner’s Manual supplied with the Heater. Ventilation Set the thermostat to the fan only mode. The heater’s fan will start and operate continuously. Cooling On a call for cooling the compressor and outdoor fan/s will start and cycle in response to the thermostat to maintain the desired room temperature. The heater’s fan will operate continuously or will cycle with compressor depending on the selected fan mode. Fault Lockout When the high or low pressure limit switch trips the compressor and outdoor fan/s are disabled. The compressor and outdoor fan will remain off until the system is reset via thermostat or on/off switch.

MAINTENANCE AND SERVICE MAINTENANCE To ensure continuing high performance and to minimise the possibility of premature equipment failure, periodic maintenance must be performed on the air conditioning equipment. The units should be inspected at least once each year by a qualified service person. The minimum maintenance requirements for this equipment are as follows: Monthly • Inspect Return Air Filters. Replace throwaway type filters when they become clogged with dust and lint or clean

cleanable type filters monthly. Yearly • Inspect indoor coil, drain pan and condensate drain. Clean when necessary. • Inspect the heater’s fan motor and wheel for cleanliness and alignment. Clean and align the motor assembly

where applicable. • Inspect outdoor coil. Clean when necessary. • Inspect outdoor fans and motors. Ensure that fan blades are clean and adequately balanced. • Inspect the unit cabinet and insulation for damage and corrosion. Repair where necessary. Check for vibration

and excessive noise. Correct where necessary. • Inspect refrigerant tubing for oil accumulations. If oil is detected, leak test refrigerant tubing using an electronic

leak detector or liquid soap solution. • Check refrigerant charge by measurement of superheat and subcooling. Where necessary, adjust charge to

achieve optimum performance. • Check the tightness of electrical connections.
