Refrigerant pipe installation
Selecting the insulation of refrigerant pipe
 Insulate the gas pipe and liquid pipe by referring to the thickness of insulator for each pipe size.
 The standard condition is 30°C(86°F), with humidity less than 85%. In the conditions of high humidity, use one grade
thicker.

Insulating refrigerant pipe
 You must insulate refrigerant pipe, Y-joint, header joint, and pipe connection area.
 If you insulate the pipes, the condensed water does not fall from the pipes.
 Check if there are any insulation cracks on the bent pipe.
Insulation
Install the insulation to be
overlapped
Fix securely without any gap.

• The insulation of the gas and liquid pipes can be in
contact with each other but they should not press
excessively against each other.
• When contacting the gas side and liquid side pipe, use
thicker insulation.
• When installing the gas side and liquid side pipes, leave
10mm (3/8inch) of space.
• When contacting the gas side and liquid side pipe, use
thicker insulation.
