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.

Outdoor condensation drainage (Heat pump type only)

When the unit is heating, the condensing water and defrosting
water can be out reliably through the drain house.

Installation

:

Install the outdoor drain elbow in 

ɸ

25 hole on the base

plate, and joint the drain hose to the elbow, so that the
waste water formed in the outdoor unit can be drained
out to a proper plate.

CHECK AFTER INSTALLATION AND TEST 
OPERATION

Check after installation

Electrical Safety Check

1. If the supply voltage is as required.
2. If there is any faulty or miss connection in each of the power, signal and grounding wires.
3. If the grounding wire of the air conditioner is securely grounded.

Installation Safety Check

1. If the installation is secure.
2. If the water drain is smooth.
3. If the wiring and piping are correctly installed.
4. Check that no foreign matter or tools are left inside the unit.
5. Check the refrigerant pipeline is protected well.

Leak test of the refrigerant

Depending on the installation method, the following methods may be used to check for suspect leak, on areas 
such as the four connections of the outdoor unit and the cores of the cut-off valves and t-valves:
1.  Bubble method: Apply of spray a uniform layer of soap water over the suspected leak spot and observe carefully 

for bubble.

2.  lnstrument method: Checking for leak by pointing the probe of the leak detector according to the instruction to 

the suspect points of leak.

Note

: Make sure that the ventilation is good before checking.
