Step six: neaten the pipes
1. The pipes should be placed along the wall,
bent reasonably and hidden possibly. Min.
semidiameter of bending the pipe is 10cm.
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.

in -0.1MPa. If the pressure decreases, there may be leakage.
5. Remove the piezometer, open the valve core of liquid valve and gas valve
completely with inner hexagon spanner.
6. Tighten the screw caps of valves and refrigerant charging vent.
7. Reinstall the handle.
Leakage detection
1. With leakage detector:
Check if there is leakage with leakage detector.
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.
● 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
● 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.
