Installation Manual Installation Manual
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.
4. Close the vacuum pump and maintain this status for 1-2min to
check if the pressure of piezometer remains 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 valve and refrigerant charging vent.
7. Reinstall the handle.
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.

7.5 Check after installation
Check according to the following requirement after finishing installation.
Items to be checked Possible malfunction
Has the unit been installed firmly The unit may drop, shake or emit noise
Have you done the refrigerant leakage test?
It may cause in sufficient cooling(heating)
capacity.
Is heat insulation of pipeline sufficient It may cause condensation and water dripping.
Is water drained well? It may cause condensation and water dripping.
Is the voltage of power supply according to the voltage marked on the
nameplate?
It may cause malfunction or damaging the parts.
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 in sufficient 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 in sufficient cooling(heating)
capacity.
7.6 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 HEATto check whether the operation is normal or not.
● If the ambient temperature is lower than 16
℃
, the air conditioner can’t start cooling.
