ENGLISH
1.
To avoid condensation problems, place
T13.0 or thicker
Acrylonitrile Butadien Rubber
separately around each
refrigerant pipe.
Always make the seam of pipes face upwards.
Note
No gap
NBR(T13.0 or thicker)
2.
Wind insulating tape around the pipes and drain hose avoiding
to compress the insulation too much.
Insulation cover pipe
Indoor unit
Be sure to overlap
the insulation
Insulation pipe
Must fit tightly against
body without any gap.
3.
Finish wrapping insulating tape around the rest of the
pipes leading to the outdoor unit.
4.
The pipes and electrical cables connecting the indoor unit
with the outdoor unit must be fixed to the wall with
suitable ducts.
Once you have checked that there are no leaks in the system,
you can insulate the piping and hose.
Insulation
Drain pipe and Drain Hose Installation
1.
Install the drain pipe as shortly as possible.
Give a slightly slant to the drainpipe for proper drainage of
condensate water.
There must be no gap on the connected part so that the
drainpipe is not separated from the flexible hose.
2.
Insulate the drainpipe, and then fix it as indicated.
Whole drainpipe should be insulated by 5t(or more)
insulation to prevent water condensation.

Indoor
Unit
All refrigerant connection must be accessible, in order
to permit either unit maintenance or removing it
completely.
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.

5.
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 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.
Insulator’s heat-resistance temperature should be more
than 120 °C.
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.)
<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.
