8. Insert hexagonal wrench into the packed valve
(high pressure valve) and open the valve by
turning the wrench 1/4 counterclockwise. Listen
for gas to exit the system, then close the valve

after 5 seconds.
9. Watch the Pressure Gauge for one minute to
make sure that there is no change in pressure. It

should read slightly higher than the atmospheric
pressure.
10. Remove the charge hose from the service port.
11. Using hexagonal wrench, fully open both the high
pressure and low pressure valves.
OPEN VALVE STEMS GENTLY
When opening valve stems, turn the hexagonal wrench until it hits against the stopper. DO NOT
try to force the valve to open further.
12. Tighten valve caps by hand, then tighten it using the proper tool.
13. If the outdoor unit uses all vacuum valves, and the vacuum position is at the main valve, the system is
not connected with the indoor unit. The valve must be tightened with a screw nut. Check for gas leaks
before operation to prevent leakage.
• After confirmation of the above conditions, follow these guidelines when performing wiring:
• Refrigerant charging must be performed after wiring, vacuuming, and the leak testing.
• DO NOT exceed the maximum allowable quantity of refrigerant or overcharge the system.
Doing so can damage the unit or impact it's functioning.
• Charging with unsuitable substances may cause explosions or accidents. Ensure that the
appropriate refrigerant is used.
• Refrigerant containers must be opened slowly. Always use protective gear when charging
the system.
• DO NOT mix refrigerants types.
• For the R32 refrigerant model, make sure the conditions within the area have been made
safe by control of flammable material when the refrigerant added into air conditioner.
Depending on the length of connective piping or the pressure of the evacuated system, you made need to
add refrigerant. Refer to table below for refrigerant amounts to be added:
