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.

unit level:
Wrap the piping and connecting cable from bottom to top.
Form a trap to prevent water from entering the room.
Secure the wrapped piping along the exterior wall using
saddle or equivalent.
seal small openings
around piping with a
gum type sealer

Note: all refrigerant piping must be protected against
mechanical damage
Electrical safety rules before starting the installation:
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.
9. Before performing any electrical work, turn off the main power to
the system.
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

WARNING
warning
All wires between indoor and outdoor units must be connected
by a qualified electric contractor.
If the length of the power cord is not enough, please contact your
installer for new a power cord. Lengthening the power cord by
yourself is dangerous and illegal.
NOTE: Powered accessories cannot be connected to these
wiring points
After tightening the screws, pull the wire slightly to confirm whether
it’s firm or not.
Do not connect two power cables together to supply power to the
air conditioner.
Do not extend the power cable conductor by cutting or splicing.

WARNING
caution
After confirming the above conditions, prepare the wiring as
follows:
• The screws which fasten the wiring to the terminal block may
come loose from vibrations during transportation.
• Check and make sure all screws are well fixed. Otherwise, it
could cause burn-out of the wires.
• Be sure the circuit capacity is sufficient.
• Ensure the starting voltage is maintained at over 90% of the
rated voltage marked on the nameplate.
• Confirm that the cable thickness is as specified in the power
source specification.
• Always install a Residual Current Device (RCD).
• The following may be caused by voltage drop: vibration of a
contactor, which will damage the contact point, fuse blowing,
disturbance of the normal function of the overload.
• The means for disconnection from a power supply shall be
incorporated in the fixed wiring and have an air gap contact
separation of at least 3mm in each active (phase) conductor.
NOTE: Powered accessories cannot be connected to these
wiring points.
