Thermal insulation process

Apply thermal insulation for the pipes separately 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 248 °F (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.

REQUIREMENT

• 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.)

• Wrap heat insulator with its slits facing up (ceiling

side).
