2. With soap water:
If leakage detector is not available, please use soap water for leakage detection.
Apply soap water at the suspected position and keep the soap water for more
than 3min. If there are air bubbles coming out of this position, there's a leakage.
33
Check after installation
● Check according to the following requirement after finishing installation.
Items to be checked

Is electric wiring and pipeline installed
correctly?
It may cause malfunction or damaging
the parts.
Is the unit grounded securely?
It may cause electric leakage.
Does the power cord follow the specification?
It may cause malfunction or damaging
the parts.
Is there any obstruction in the air inlet
and outlet?
It may cause insufficient cooling
(heating) capacity.
The dust and sundries caused during
installation are removed?
It may cause malfunction or damaging
the parts.
The gas valve and liquid valve of
connection pipe are open completely?
It may cause insufficient cooling
(heating) capacity.
Test operation
1. Preparation of test operation
● The client approves the air conditioner.
● Specify the important notes for air conditioner to the client.
2. Method of test operation
● Put through the power, press ON/OFF button on the remote controller to start
operation.
● Press MODE button to select AUTO, COOL, DRY, FAN and HEAT to check
whether the operation is normal or not.
● If the ambient temperature is lower than 16℃ , the air conditioner can’t
start cooling.

4. The additional refrigerant oil and refrigerant charging required after prolonging
connection pipe
● After the length of connection pipe is prolonged for 10m at the basis of
standard length, you should add 5ml of refrigerant oil for each additional 5m
of connection pipe.
● The calculation method of additional refrigerant charging amount (on the basis
of liquid pipe):
Additional refrigerant charging amount = prolonged length of liquid pipe ×
additional refrigerant charging amount per meter
● Basing on the length of standard pipe, add refrigerant according to the
requirement as shown in the table. The additional refrigerant charging amount
per meter is different according to the diameter of liquid pipe. See the
following sheet.
