The designs and shape are subject to change according
to the model.
Step 12 Draining the water naturally
When using the air conditioner in the heating mode, ice
may accumulate . During de-icing (defrost operation), the
defrosting water must be drained off safely.
•
Do not install a drain hose, a drain plug and a cap.
(Let the water drain naturally).
•
Ice may form on the ground. Take appropriate
measures to prevent ice formation.

Step 13 Insulating the refrigerant pipes
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.
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 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. If
installing in an unfavourable conditions, use thicker
one.
•
Insulator's heat-resistance temperature should be
more than 120°C.
