Installation Procedure
Step 12 Insulating the refrigerant
pipes
1 Once you have checked that there are no leaks in the
system, you can insulate the piping and hose.
No gap
NBR
NOTE
• When insulate the pipe, be sure to overlap the
insulation.
• The insulation has to be produced in full compliance
of European 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.
CAUTION
• When insulating the pipe, use non-slit insulator.
2 Select the insulation of the refrigerant pipe.
• Insulate the gas side and liquid side pipe referring
to the thickness according to the pipe size.
• Less than Indoor temperature of 86℉(30℃) 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 unfavourable conditions,
use thicker one.
• Insulator’s heat-resistance temperature should be
more than 248℉(120℃).

• When installing insulation in places and
conditions below, use the same insulation that is
used for high humidity 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.)
<Geological 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.
Step 13 Checking the earthing
If the power distribution circuit does not have a earthing
or the earthing does not comply with specifications, an
earthing electrode must be installed. The corresponding
accessories are not supplied with the air conditioner.
1 Select an earthing electrode that complies with the
specifications given in the illustration.
