2. Flaring Work and Connection of Piping
Main cause for refrigerant leakage is due to defect in
the flaring work. Carry out correct flaring work using the
following procedure.
1. Cut the pipes and the cable.
• Use the piping kit accessory 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. Air purging
Required tools : hexagonal wrench, adjustable
wrench, torque wrenches, wrench to
hold the joints, and gas leak
detector.
The air in the indoor unit and in the piping must be
purged. If air remains in the refrigeration pipes, it will
affect the compressor, reduce to cooling capacity, and
could lead to a malfunction.
The additional gas for air purging has been charged
in the outdoor unit.
However, if the flare connections have not be done
correctly and there gas leaks, a gas cylinder and the
charge set will be needed.

• Procedure
\
(1) Connect the charge hose to the charging
cylinder.
– Connect the charge hose which you disconnected from the vacuum pump to the valve
at the bottom of the cylinder.
– If you are using a gas cylinder, also use a scale
and revers the cylinder so that the system can
be charged with liquid.
(2) Purge the air from the charge hose.
– Open the valve at the bottom of the cylinder
and press the check valve on the charge set to
purge the air. (Be careful of the liquid
refrigerant). The procedure is the same if
using a gas cylinder.
(3) Open the valve (Lo side on the charge set and
charge the system with liquid refrigerant.
– If the system can not be charged with the
specified amount of refrigerant, it can be
charged with a little at a time (approximately
150g each time) while operating the air
conditioner in the cooling cycle; however, one
time is not sufficient, wait approximately 1
minute and then repeat the procedure
(pumping down-pin).
This is different from previous procedures.
Because you are charging with liquid refrigerant
from the gas side, absolutely do not attempt to
charge with larger amounts of liquid refrigerant
while operating the air conditioner.
(4) Immediately disconnect the charge hose from
the 3-way valve’s service port.
– Stopping partway will allow the gas to be
discharged.
– If the system has been charged with liquid
refrigerant while operating the air conditioner
turn off the air conditioner before disconnecting
the hose.
(5) Mount the valve stem nuts and the service
port nut.
– Use torque wrench to tighten the service port
nut to a torque of 1.8 kg.m.
– Be sure to check for gas leakage.
