CONDENSATE DRAIN INSTALLATION
A condensate drainage point is provided in the base of the outdoor unit. For the purposes of drainage a barbed elbow is also supplied. Insert the barbed elbow into the drainage point of the outdoor unit as shown. A drainage hose (installer to supply) will need to be fitted.

Drainage of the condensate must conform with all local regulations and municipal building codes including local OH&S requirements.

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

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

CAUTION 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

1.  Remove the caps from the vapor valve, vapor valve service port, and liquid valve.
2.  Connect the charge hose from the low-pressure gauge (manifold gauge set) to the vapor valve service port.
3.  Open the low-pressure gauge valve (manifold gauge set), turn on the vacuum pump and run for a minimum of 15 minutes.
4. Close the low-pressure gauge valve (manifold gauge set) and turn off the vacuum pump.
5. Wait 2 minutes to allow pressure to stabilize, then check that the low pressure gauge is maintaining a pressure of -100 kPa (-76 cmHg).
6. . Disconnect charge hose from the vapor valve service port and replace the vapour valve service port cap.
7.  Open both the vapour and the liquid valves to charge the refrigerant system for test running.
8.  Test run the system through both heating and cooling cycles and test for leaks.
9.  Replace the vapour and liquid valve caps. Both the vapour and liquid valve caps MUST BE on tight.
10.  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.

FINAL CHECKLIST

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

If you have answered no to any of the above, you must check and correct before appliance hand-over to customer.
