Insulation
Once you have checked that there are no leaks in the system, you can insulate the piping and hose .
1 . To avoid condensation problems, place an insulator around each refrigerant
pipe .
• When insulate the pipe, be sure to overlap the insulation .
• The insulation has to be produced in full compliance of European
NOTE
regulation reg . EEC / EU 2037/ 2000 that requires the use of
sheaths insulation form without using CFC and HCFC gases for
health and the environment .
• When insulating the pipe, use non-slit insulator .
CAUTION
2 . Select the insulation of the refrigerant pipe .
f Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size .
f
f Less than Indoor temperature of 86 °C and humidity of 85 % is the standard condition . If installing in a high humidity
f
condition, use one grade thicker insulator by referring to the table below . If installing in an unfavorable conditions, use
thicker one .
f Insulator's heat-resistance temperature should be more than 248 °F .

f When installing insulation in places and conditions below, use the same insulation that is used for high humidity
f
conditions .
<Geological condition>
- 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 . )
<Operation purpose condition>
- Restaurant ceiling, sauna, swimming pool etc .
<Building construction condition>
- 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 .
