1. Hang the mounting slots of the indoor unit on the upper portion of the mounting plate. Ensure that the hooks are properly seated on the plate.
2.  Push the unit towards to the wall, and hook the unit onto the lower fixing hook.

Ensure that there is no leakage from the drainpipe connection and that the drainpipe has a continuous fall to the outside. Ensure that all wall penetrations are sufficiently weatherproofed.

OUTDOOR UNIT

Electrical Connections

Must be installed, maintained and removed by authorised persons in accordance with AS/NZS 3000 and to all other relevant local regulations and municipal building codes including OH&S requirements. Ensure electric wiring is installed properly. Improper installation may cause malfunction, fire, or electric shock. The unit must be earthed following local electrical codes.

1.  Remove the wiring cover.
2.  Secure the electrical cable(s) and power cable onto the control board with the cable clip.
3.  Connect the cables as shown on the drawing below.

•  Re-install the wiring cover.

DRED Connection (optional)
This appliance is supplied with a DRED interface, the interface provides two connection methods of either a four-wire terminal connection or an RJ45 socket.

Must be installed, maintained, and removed by authorized persons in accordance with AS/NZS 3000 and to all other relevant local regulations and municipal building codes including OH&S requirements.
Ensure electric wiring is installed properly. Improper installation may cause malfunction, fire, or electric shock.

• Remove the wiring cover.
•  Connect the power feed to the terminal block as shown on the drawing below.
•  Connect the communication cable to the DRED interface using either the four-wire terminal connections or RJ45 socket provided.

REFRIGERANT PIPES

Flaring

•   The main cause for refrigerant leakage is due to defects with the flaring work.

•  The installer must ensure that all piping used complies with both:
  AS/NZS 1571:1995 – Copper – Seamless tubes for air conditioning and refrigeration.
  AS/NZS 4041:2006 – Pressure piping.

•  All pipework and fittings should be thoroughly examined for cleanliness and suitability for the system and refrigerant prior to assembling.

•  All unsealed tubing must be thoroughly inspected and, if necessary, cleaned before assembly to remove any copper residue and/or scale particles such as dirt or metal.

•  Metal filings must not be left in pipework after cutting as they can cause damage compressor (i.e. shaft seals, bearings, etc.).

•  Prior to assembly, refrigeration pipes must be clean and burr free. They must not be crushed or kinked.

•  For flare connections, a suitable lubricant must be used between the back of the flare and the nut to avoid tearing the flare when tightening the nut.

Connecting Vapour / Liquid Pipes To Indoor & Outdoor Units

• Align the centre of the pipes.
• Sufficiently tighten the flare nut with fingers, then tighten with a spanner and torque wrench.

To prevent heat loss and wet floors due to dripping of condensation, both pipes must be properly insulated.

• Ensure the joint nut is tightened firmly to avoid leakage.
• Ensure that both the connections and the refrigerant pipes are wrapped with insulation material.

Air Purging & Leakage Test

• DO NOT mix any substance other than the specified refrigerant (R32) into refrigerant system.

• When refrigerant gas leaks occur, ventilate the room immediately.

• R32, as well as other refrigerants, should always be recovered and never be released directly into the environment.

• Use a vacuum pump for R32 exclusively. Using the same vacuum pump for different refrigerants may damage the vacuum pump or the unit.\

• It is necessary to purge air and check for gas leakage after piping work is completed.

• If using additional refrigerant, perform air purging from the refrigerant pipes and indoor unit using a vacuum pump, then charge additional refrigerant.

• Use a hex socket (3/16″) to operate the service valves.

• All refrigerant pipe joints to be tightened with a torque wrench at the specified torque.

Evacuation Vacuum Method / Leak Test

•  Remove the caps from the vapor valve, vapor valve service port and the liquid valve.
•  Connect the charge hose from the low-pressure gauge (manifold gauge set) to the vapour valve service port.
•  Open the low-pressure gauge valve (manifold gauge set), turn on the vacuum pump and run for a minimum of 15 minutes.
•  Close low-pressure gauge valve (manifold gauge set) and turn off the vacuum pump.
•  Wait 2 minutes to allow pressure to stabilize, then check that the low-pressure gauge is maintaining a pressure of -100 kPa (-76 cmHg).
•  Disconnect the charge hose from the vapour valve service port and replace the vapor valve service port cap.
•  Open both the vapor and the liquid valves to charge the refrigerant system for test running.
•  Test run the system through both heating and cooling cycles and test  for leaks.
•  Replace the vapour and liquid valve caps.

Both the vapour and liquid valve caps MUST BE on tight.

The system is now ready to run.
Adding Refrigerant for Longer Line Length
Additional refrigerant for longer piping runs can be added either at the time of evacuation of the new installation or whilst the unit is operating, see “Pipe Length & Elevation Limits” on page 8.

• It is very easy to overcharge, take caution in charging refrigerant liquid and keep your eye on the scales to avoid overcharging the unit.
• Take care not to discharge refrigerant into the atmosphere during installation, re-installation, repair or service.

The checklist is ONLY to be completed by an Authorised Person.
