addition to applying the general heat insulation materials. Enough heat insulation materials should
also be applied to the refrigerant joint and the pipe joint.
Note: the heat insulation of drain pipe refer to the installation of indoor unit.
Please use heat-resistant materials as heat insulation material of the air-side pipe. (e.g., EPT)
Cover heat insulation materials separately at the liquid side and the air side. Moreover, perform
heat insulation thoroughly for the air-side pipes of the indoor unit, and prevent water from
dripping outside the unit.
After applying the auxiliary heat insulation materials, use vinyl resin tape to seal refrigerant pipe
and drainage pipe to prevent water leak.
