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.
Notes: The heat insulation of drain pipe refers 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.

Electric Connection
6.1 Caution
Power supply of indoor unit and outdoor unit must be within normal voltage range.
Power wiring, control wiring, disconnect switches and over-current protection must be supplied by the
installer. Wire size should be sized per requirement.
The power cord type designation is H07RN-F.
Before connecting wire, please switch off the power supply. Otherwise, it may cause electric shock.
External wiring of the indoor unit must be grounded that means power wire of outdoor unit shall be
connected with external grounding wire reliably.
Electrical wiring must be done by professionals, and wiring according to the wiring label.
Run power wiring from the disconnect switch to the unit.
Route wires from disconnect through power wiring opening provided and into the unit control box.
Install the proper size time-delay fuses or circuit breaker, and make the power supply connections.
