Installation Procedure
Insulating pipes
• The insulation of the gas and liquid pipes can be in contact with each
other but they should not press excessively against each other.
• When the gas side and liquid side pipes are contacting each other,
increase the thickness of the insulation by one grade.

• When installing the gas side and liquid side pipes, leave at least
10mm of space.
• When the gas side and liquid side pipes are contacting each other,
increase the thickness of the insulation by one grade.

CAUTION
• Install the insulation without any gaps or cracks and use
adhesive on the connection part of it to prevent moisture from
entering.
• Bind the refrigerant pipe with insulation tape if it is exposed to
outside sunlight. (When binding the pipe with finishing tape,
be careful not to reduce the thickness of the insulation.)
• Install the refrigerant pipe respecting that the insulation does
not get thinner on the bent part or hanger of pipe.
• When the thickness of insulation is reduced, reinforce the
reduced thickness with additional insulation.

Insulate the distribution header
• Fix the distribution header with a cable tie and cover the
connected part.
• Insulate the distribution header and the welded part and wrap
the connected part with an adhesive insulation tape to prevent
dew formation.

• Fix the distribution header with a hanger after insulating it.
Insulating the branch joint
• Tightly attach the insulator, provided with the branch joint,
to the separately purchased insulator. Wrap the connected
part with an insulator (separately purchased item) that has
thickness of at least 10mm.
• Use an insulator that resist heat up to 120°C. Wrap the branch
joint with an insulation that has thickness of at least 10mm.
Fix securely without any gap.
