INSULATING THE REFRIGERANT PIPE
Insulating the branch joint
Outdoor joint & gas side of the outdoor unit
•
Use an insulation that should be able to handle the interior temperature over 120°C.
•
Wrap the branch joint with an insulation of a thickness of at least 10mm as shown in the
picture.
•
Wrap the connected part between the Outdoor joint and the gas side of the outdoor unit
to prevent it from defrosting.
Insulating the interior of the outdoor unit pipe
•
Insulate the whole service valve of the outdoor unit with a pipe insulation.
•
Seal the gap between the outdoor unit pipe and the insulation.
Rainwater and dewdrops may soak through the gap between the pipe and the insulation
of the outdoor unit installed on the outside.
•
Separate the cover of the pipe and close it after insulation work.
Remove a knock-out hole cover that installed the pipe and use it.
If the extra knock-out hole is open, small animals such as squirrels and rats may get into
the unit through the hole and the unit may be damaged.
