• 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 right figure. Each unit must be purged in turn.

1.Check the piping connections.

2.Connect the charging hose of low pressure side of manifold gauge to the packed valve having a service port (3/8" service valve) as shown at the figure.

3.Open the valve of the low pressure side of manifold gauge counter- clockwise.

4.Purge 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 10 minutes.

•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.

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

6.Mount 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.

7.Check 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.
