Refrigerant pipe connection
The main cause of refrigerant leakage is due to defects in the
flaring work. Carry out flaring work using the following procedure:
Note: When using refrigerant R32, a reusable flared connection is
the only allowed pipework on the outside of any building.
Hence the supplied "once only" flare fitting must be used unless all
welded connections are used. If welded connections are used, no
low temperature solder is permitted.
a. Cut the pipes and the cable
Use the piping kit accessory (if applicable) or pipes purchased
locally. Measure the distance between the indoor and the
outdoor unit. Cut the pipes a little longer than the measured
distance. Cut the cable 1.5m longer than the pipe length.

1. A dedicated power supply circuit and breaker should be
provided for the products which are not supplied with a
service cord and plug in accordance with local electrical safety
regulations.
2. The circuit breaker must have the functions of magnetic tripping
and heat tripping to prevent short circuit and overload.
3. The appliance shall be installed in accordance with national
wiring regulations.
4. A circuit breaker with proper capacity must be installed
according to AS3000 and applicable local electrical safety
regulations.
5. In case of problems in power supply, the air conditioner must not
be installed before the customer fixes the problem.
6. Be sure the power supply matches the air conditioner.
7. Ensure the live wire, neutral wire and earth wire in the power
socket are properly connected.
8. Inadequate or incorrect electrical connections may cause electric
shock, fire or some electrical parts to malfunction.

Earthing requirements
1. Air conditioners are type 1 electric appliances. The unit must be
reliably earthed and connected by a qualified electrician.
2. The yellow-green wire in the air conditioner is the earthing wire
which cannot be used for any other purposes. Improper earthing
may cause electric shock.
3. The earth resistance must comply to national wiring regulations.
4. The user’s power must have reliable earthing terminal. Do not
connect the earthing wire with the following:
• Water pipe
• Gas pipe
• Contamination pipe
