Energy Label
Annual energy efficiency perfomance ratio is
calculated by overall capacity and average
operaing time (apr 500 hours) multiplication in
full-load coling mode operation.
Cooling capacity
is device cooling capaciy (demanded in kWh) in
full-load cooling mode operation. ERR energy
label index is ratio of cooling capacity to its
electric energy input attainment. Energy label
depends on ERR index rate.

Vacuum pumping
Use vacuum pump
1. Remove the valve caps on
the liquid valve and gas
valve and the nut of refri gerant charging vent.
2. Connect the charging hose
of piezometer to the refri gerant charging vent of gas
valve and then connect the
other charging hose to the
vacuum pump.
3. Open the piezometer com pletely and operate for
10-15min to check if the
pressure of piezometer re mains in -0.1MPa.
4. Close the vacuum pump
and maintain this status for
1-2min to check if the pres sure 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 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
startcooling.

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.
