Performing Leak Test & Heat Insulation
Leak test
In order to detect gas leak from the indoor unit, use nitrogen to check the
connection areas of the refrigerant pipes.
Leak test
• Please refer to the leak test in the installation manual for the
outdoor unit.
NOTE
❋ The design and shape are subject to change
according to the model.
Insulation
1. Insulate the refrigerant pipe.
f Make sure to insulate the refrigerant pipe, connector and connection
area.
- If the pipes are insulated, condensation will not come out from the
piping and the capacity of Fresh duct will be increased.
f Check for cracks in the insulation cover pipe out at the bended area.
