Vacuuming (Gas R32)

Exclusive R32 refrigerant pump must be used in making R32 refrigerant vacuum.

Before working on the air conditioner, remove the cover of 
the stop valve(gas and liquid valves)and be sure to retighten it 
afterward.(to prevent the potential air leakage).
1.  To prevent air leakage and spilling tighten all connecting 

nut of all flare tubes.

2.  Connect the stop valve, charge hose, manifold valve, and 

vacuum pump.

3.  Fully open the handle Lo of the manifold valve and 

apply vacuum for at least 15 minutes and check that the 
compound vacuum gauge reads -0.1MPa (-76cmHg).

4.  After applying vacuum, fully open the stop valve with a hex 

wrench.

5.  Check that both indoor and outdoor connections are free 

of air leakage.

Expelling the air (Gas R410a)

Outdoor unit refrigerant discharging method.

After the pipe side connection is complete, proceed as follows.

Vacuum Pumping Method (R410A refrigerant evacuation must use the vacuum pumping method)

.

Before working on the air conditioner, remove the cover 
of the stop valve (gas and liquid valves) and be sure to 
retighten it afterward (to prevent the potential air leakage).

1.  To prevent air leakage and spilling tighten all 

connecting nut of all flare tubes.

5.  Check that both indoor and outdoor connections are 

free of air leakage.

Fully open 

the spindles 

of the liquid 

end and of

the other two 

ends.

Check that all

connections 

are free of air 

leakage.

The installing torque 

is the same as that 

of the gas end of the 

indoor unit.
