Performing Leak Test & Insulation (Continued)

Select the insulation of the refrigerant pipe.
Insulate the gas side and liquid side pipe referring to the thickness
according to the pipe size.
Indoor temperature of 30°C(86°F) and humidity of 85% is the standard
condition. If installing in a high humidity condition, use one grade thicker
insulator by referring to the table below.
If installing in an unfavorable conditions, use thicker one.
Insulator’s heat-resistance temperature should be more than 120°C(248°F).

When installing insulation in places and conditions below, use the same insulation
that is used for high humidity conditions.
- High humidity places such as shoreline, hot spring, near lake or river, and
ridge (when the part of the building is covered by earth and sand.)
- Restaurant ceiling, sauna, swimming pool etc.
- The ceiling frequently exposed to moisture and cooling is not covered.
e.g. The pipe installed at a corridor of a dormitory and studio or near an
exit that opens and closes frequently.
- The place where the pipe is installed is highly humid due to the lack of
ventilation system.
Refrigerant pipe before EEV kit and MCU or without EEV kit and MCU
You can contact the gas side and liquid side pipes but the pipes
should not be pressed.
When contacting the gas side and gas side pipe, use 1 grade thicker
insulator.
Refrigerant pipe after EEV kit and MCU
Install the gas side and liquid side pipes, leave 10mm(3/8") of space.
When contacting the gas side and liquid side pipe, use 1 grade
thicker insulator.

Install the insulation not to get wider and use the adhesives
on the connection part of it to prevent moisture from entering.
Wind the refrigerant pipe with insulation tape if it is exposed to
outside sunlight.
Install the refrigerant pipe respecting that the insulation does not
get thinner on the bent part or hanger of pipe.
Add the additional insulation if the insulation plate gets thinner.
