Connecting Up and Removing Air In the Circuit
The outdoor unit is loaded with sufficient R-22 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/heating
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.
<None>Adding Refrigerant
Refrigerant must be added if the piping measures more than 5 metres
in length (maximum of “A” metres). This operation can only be performed by a qualified refrigeration specialist.
