installing your air conditioner
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
2.
Wind insulating tape around the pipes and drain hose
avoiding to compress the insulation too much.
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
All refrigerant connection must be accessible, in order
to permit either unit maintenance or removing it
completely.
CAUTION
No gap
NBR(T13.0 or thicker)
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.
The thickness according to the pipe size is a standard of
the indoor temperature of 27°C and humidity of 80%.
If installing in an unfavorable conditions, use thicker one.
Insulator’s heat-resistance temperature should be more
than 120°C.

If you install the pipe
underground, at the seaside,
a spa or on the lake, use 1 grade
thicker one according to the
pipe size.

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.
CAUTION
Additional insulation

CAUTION
Must fit tightly against body
without any gap.

Indoor unit
Be sure to overlap
the insulation
Drain hose installation
When installing the drain hose for the indoor unit,
check if condensation draining is adequate.
When passing the drain hose through the 65mm hole drilled
in the wall, check the following:
The hose must
NOT slant upwards.
The end of the drain hose must
NOT be placed under water.
Do NOT bend the hose in
different directions.
Keep a clearance of at least
5cm between the end of the
hose and the ground.
5cm
less
Do NOT place the end of the
drain hose in a hollow.
