4. Heat Insulation of Refrigerant Pipe
In order to prevent faults caused by condensate of the refrigerant pipe and drain pipe, perform
condensate prevention and heat insulation properly. If it is forecast that high humidity and
temperature environment (Condensate temperature is over 23°C) 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/m
2
) 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.
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.
5. Electric Connection
5.1 Caution
Use special power supply for the air conditioner. Design power supplies specific to the indoor
unit and outdoor unit. The supply voltage must comply with the nominal voltage.
The external supply circuit of the air conditioner must have a ground wire, and the power supply
ground wire of the indoor unit must be connected with the external ground wire firmly.
The wiring must be performed by professional technicians according to the circuit diagram
labels.
Distribute the wires according to the relevant electric technical standards promulgated by the
State, and set the Residual Current-operated Circuit Breaker (RCCB) properly.
