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.

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

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 vapour valve, vapour valve service port and the liquid valve.
2. Connect charge hose from the low pressure gauge (manifold gauge set) to the vapour 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 low pressure gauge valve (manifold gauge set) and turn off vacuum pump.
5. Wait 2 minutes to allow pressure to stabilise, then check that the low pressure gauge is maintaining a pressure of -100 kPa (-76 cmHg).
6. Disconnect charge hose from the vapour valve service port and replace the vapour valve service port cap.
7. Open both the vapour and the liquid valves to charge the refrigerant
