The outdoor unit is loaded with sufficient R22 refrigerant for 5 metres of piping. The air in the indoor unit and in the pipe must be purged.

If air remains in the refrigeration pipes, it will affect the compressor, reduce to cooling capacity and could lead to a malfunction.

Refrigerant for air purging is not charged in the outdoor unit. Use Vacuum Pump as shown at the figure.

1Connect each assembly pipe to the appropriate valve on the outdoor unit and tighten the flare nut.

2Referring to the illustration opposite, tighten the flare nut first manually and

then with a torque wrench, applying the following torque.

3Connect the charging hose of low pressure side of manifold gauge to the packed valve having a service port as shown at the figure.

4Open the valve of the low pressure side of manifold gauge counterclockwise.

5Purge the air from the system using vacuum pump for about 10 minutes.

-Close the valve of the low pressure side of manifold gauge clockwise.

-Make sure that pressure gauge show -0.1MPa(-76cmHg) after about

-10minutes.

-This procedure is very important in order to avoid gas leak.

-Turn off the vacuum pump

-Remove the hose of the low pressure side of manifold gauge.

6Set valve cork of both liquid side and gas side of packed valve to the open position.

7Mount the valve stem nuts and the service port cap to the valve, and tighten them at the torque of 183kgf•cm with a torque wrench.

8Check for gas leakage.

-At this time, especially check for gas leakage from the 3-way valve’s stem nuts, and from the service port cap.

Adding Refrigerant

Refrigerant must be added if the piping measures more than 5 metres in length. This operation can only be performed by a qualified refrigeration specialist.
