Step 9 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 Acrylonitrile
Butadien Rubber separately around each refrigerant
pipe.
No gap
CAUTION
• The insulation has to be produced in full compliance
with European regulation EEC / EU 2037 / 2000
requring the use of sheaths insulation without using
CFC and HCFC gases for heating and the environment.
NOTE
• Always make the seam of pipes face upwards.
2 Wind insulating tape around the pipes and drain hose
avoiding compressing the insulation too much.
Indoor unit
CAUTION
• Be sure to wrap insulation tightly without any gaps.
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.

Be sure to overlap the insulation.
CAUTION
• Must fit tightly against body without any gap.
• Make sure that all refrigerant connection must be
accessible for easy maintenance and detachment.
• 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, noting the
insulation thickness that must differ according to the
pipe size.
• Standard: Less than an indoor temperature of 86 °F
(30 °C), with humidity at 85%. If installing in a high
humidity environment, use one grade thicker insulator
by referring to the table below. If installing in an
unfavourable environment, use thicker one.
• The heat-resistance temperature of the insulator must
be more than 248 °F (120 °C).
