PRECAUTIONS FOR UPWARD DRAIN RAISING
PIPING
• Install the drain raising pipes at a height of less than
500 mm.
• Install the drain raising pipes at a right angle to the
indoor unit. (Refer to Fig. 30)
CAUTION
If the upward running drain hose leans at a slant, the float switch will malfunction and water will leak
2. After piping work is finished, check if drainage flows smoothly.
• Open the water inlet lid, add approximately 1 liter of water slowly and check drainage flow.
(Refer to Fig. 31)

Drain piping connections
• Do not connect the drain piping directly to sewage pipes that smell of ammonia. The ammonia in the
sewage might enter the indoor unit through the drain pipes and corrode the heat exchanger.
