Thermal insulating process
• After checking the draining, wrap the supplied thermal insulation material for the drain connecting part around the
flexible hose leaving no clearance from the root of the drain pipe connecting port of the indoor unit.
• Wrap the thermal insulation material (procured locally) around the drain pipe so that it piles up on the supplied
the thermal insulation material for the drain connecting part, leaving no clearance.
CAUTION
Ensure water is poured slowly.
If water is poured vigorously, it is scattered inside of
the indoor unit resulting in a cause of unit trouble.
