1. When welding the pipe with hard solder, charge nitrogen into the pipe against oxidation. The
pressure gauge should be set at 0.02MPa.Perform the procedure with nitrogen circulation.

E. Additional refrigerant charging
Charge the additional refrigerant as liquid state with the gauge.
If the additional refrigerant can not be charged totally when the outdoor stops, charge it at the
trial mode.
If the unit runs for a long period in the state of lack of refrigerant, compressor will occur failure.

Trial operation and the performance
Heating capacity
‡ The heating mode adopts the heat pump type that absorbs outdoor heat energy and releases
into indoor. So if outdoor temperature goes down, the heating capacity will decrease.
