VACUUMING
• 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
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 Ф25 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
• 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. Instrument 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.
TEST OPERATION
• Test Operation preparation:
1. Verify that all piping and connection cables are well connected.
2. Confirm that the values at the gas side the liquid-side are fully open.
3. Connect the power cable to an independent power socket.
4. Install batteries in remote control.
Note: Make sure that the ventilation is good before testing.
• Test Operation method:
1. Turn on the power and push the ON/OFF switch button of the remote controller to start the air conditioner.
2. Select COOL, HEAT (not available on cool-only models), SWING and other operation modes with the remote
controller and see if the operation is ok.
