4. Heat Insulation of the Pipe

4.1 Heat Insulation of the Pipe
In order to prevent faults caused by condensate of the refrigerant pipe and drain pipe, perform condensate
prevention and heat insulation properly.
CAUTION:
If it is forecast that high humidity/temperature environment (condensate temperature is over 23℃) may exist in the ceiling, e.g.,
inside the ceiling with slab, ceiling which is in the same environment as the outdoor air), it is necessary to apply 10mm or thicker
adiabatic wool (16~20kg/m2 ) to the refrigerant pipe and the drain pipe in addition to applying the general heat insulation
materials. Enough heat insulation materials should also be applied to the refrigerant joint and the pipe joint.
4.2 Heat Insulation of the Drain Pipe
 Be sure to entwine heat insulation materials round the drain pipe which runs through the room.
 Carry through heat insulation for the drain pipes thoroughly.
4.3 Heat Insulation of the Refrigerant Pipe
 Please use heat-resistant materials as heat insulation materials 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 it lest water leak.
