CAUTION FOR GRADIENT OF
UNIT AND DRAIN PIPING
Lay the drain hose with a downward
inclination so water will drain out.
Front of view
• Always lay the drain with downward
inclination (1/50 to 1/100).
Prevent any upward flow or reverse flow in
any part.
• 5mm or thicker formed thermal insulator
shall always be provided for the drain pipe.
• Install the P-Trap (or U-Trap) to prevent
a water leakage caused by the blocking
of intake air filter.
Applied U-Trap Dimension
1. Install declination of the indoor unit is very important for the drain of the duct type air
conditioner.
2. Minimum thickness of the insulation for the connecting pipe shall be 5mm.
• The unit must be horizontal or declined to the drain hose connected when finished
installation.
