at liquid side and gas side.
For the thermal insulation to the pipes at gas side,
be sure to use the material with heat-resisting
temperature 120°C or higher.
Using the attached thermal insulation material,
apply the thermal insulation to the pipe connecting
section of the indoor unit securely without gap.

• Apply the thermal insulation to the pipe
connecting section of the indoor unit securely
up to the root without exposure of the pipe.
(The pipe exposed to the outside causes water
leak.)
