Attention:
1 Don't reverse the refrigerant storage bottle while it is inflating.
2 To keep the high pressure for refrigerant storage bottle, when the ambient
temperature is too low, it can be heated by warm water (around 40 ). Don't
heat it with fire or heat steam.
Connect connecting pipe
1.Wipe the airproof oil on the closing valve and the trump extended pipe;
2.Screw down the nut of connecting pipe with the wrench.(the torque as the indoor unit)

Discharge the air of the units:
(lt can use vacuum pump, too.)
Take off screw cap for closing valve and gas charging hole;
Open the closing valve with Allen wrench(turn 90 clockwise), then
push the gas charging hole about 10 seconds, (When the gas like
the fog appears, indicating the air of unit is discharge at all.)
Screw down the screw cap of gas charging hole.
Proceed leak test with leak detector or soap water.
SUPPLEMENTATION OF REFRIGERANT
Steps of supplementation of refrigerant
1 Connect the operating valve of the refrigerant storage bottle to the maintenance mouth of the stop valve
with the inflated hose.
2 Loosen the inflated hose joint a bit at the end of the maintenance mouth connected to the gas stop valve.
Open the operating valve of the refrigerant storage bottle to vent the air with refrigerant. Emergence of
mist gas shows that the air is completely vented out.
3. Observe the spring balance, fill refrigerant with the required amount.
