8.5 Air purging of the piping and indoor unit

Required tools:

Hexagonal wrench; adjustable wrench; torque wrenches, wrench to hold the joints and gas leak detector.

Note:

The air in the indoor unit and in the piping must be purged. If air remains in the refrigeration piping, it will

affect the compressor, reduce the cooling capacity, and could lead to a malfunction of unit.

Be sure, using a torque wrench to tighten the service port cap (after using the service port), so that it

prevents the gas leakage from the refrigeration cycle.

Procedure1. Recheck the piping connections.

2. Open the valve stem of the 2-way valve

counterclockwise approximately 90, wait 10

seconds, and then set it to closed position.

Be sure to use a hexagonal wrench to

operate the valve stem

3. Check for gas leakage.

Check the flare connection for gas leakage

4. Purge the air from the system.

Set the 2-way valve to the open position

and remove the cap from the 3-way valves

service port.

Using the hexagonal wrench to press the

valve core pin, discharge for three

seconds and then wait for one minute.

5. Use torque wrench to tighten the service port

cap to a torque of 1.8 kg.m. (18n.m)

6. Set the 3-way valve to the opened position.

7. Mount the valve stem nuts to the 2-way

1. Confirm that both the 2-way and 3-way valves are set to the open position.

2. Connect the charge set to the 3-way valves service port.

Leave the valve on the charge set closed.

Connect the charge hose with the push pin to the service port.

3. Open the valves (Low side) on the charge set and discharge the refrigerant until the gauge indicates

0.05 to 0.1 Mpa.

If there is no air in the refrigeration cycle [the pressure when the air conditioner is not running

is higher than 0.1Mpa, discharge the refrigerant until the gauge indicates 0.05 to 0.1 Mpa. If

this is the case, it will not be necessary to apply a evacuation.

Discharge the refrigeration gradually; if it is discharged too suddenly, the refrigeration oil will

be discharged.
