2.If the outdoor unit is higher than the wall
hole, you must set a U-shaped curve in the
pipe before pipe goes into the room, in
order to prevent rain from getting into the
room.
Vacuum pumping
Use vacuum pump
1.Remove the valve caps on the liquid valve
and gas valve and the nut of refrigerant
charging vent.
2.Connect the charging hose of piezometer
to the refrigerant charging vent of gas valve
and then connect the other charging hose
to the vacuum pump.
3.Open the piezometer completely and
operate for 10-15min to check if the
pressure of piezometer remains in -0.1MPa.

Check after installation
Leakage detection
1.With leakage detector:
Check if there is leakage with leakage
detector.
● Check according to the following
requirement after finishing installation.
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.

Test operation
1.Preparation of test operation
● The client approves the air conditioner
installation.
● 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):
● When the length of connection pipe is above 5m, add refrigerant according to the prolonged
length of liquid pipe. The additional refrigerant charging amount per meter is different according
to the diameter of liquid pipe. See the following sheet.
● Additional refrigerant charging amount = prolonged length of liquid pipe × additional
refrigerant charging amount per meter

Pipe expanding method
Note:
Improper pipe expanding is the main cause
of refrigerant leakage.Please expand the pipe
according to the following steps:
E:Expand the port
● Expand the port with expander.
A:Cut the pip
● Confirm the pipe length according to the
distance of indoor unit and outdoor unit.
● Cut the required pipe with pipe cutter.
