Leak test and insulation
2. Insulate the refrigerant pipe.
f
If the pipe is not insulated correctly, condensed water may form on the surface of the pipe or product capacity may
decrease.
f
Check that the curved part of the pipe is firmly covered by the insulator.

f
The gas pipe and liquid pipe can be attached together but make sure
that they are not excessively pressed each other.
f
When the gas pipe and liquid pipe are attached together, use 1 grade
thicker insulator.

When installing the gas pipe and the liquid pipe, allow 10 mm of space
between the pipes.

t
The insulator of the pipe should not be disconnected or
cracked. Apply adhesives on the connection part of the
insulator to prevent it from getting damp.
t
Cover the insulator of the refrigerant pipe with a sealing
tape if the insulator can be exposed to sunlight. (Make
sure that the thickness of the insulator is not decreased
by the sealing tape.)
t
When insulating the pipe, make sure that the thickness
of insulator on the curved part or on the part contacted
with the pipe hanger is not decreased.
t
When the thickness of the insulator is decreased,
increase the thickness of the insulator by using
additional insulator.
