<PRECAUTIONS FOR DRAIN RAISING PIPING>
•
Install the drain raising pipes at a height of less than 250 mm.
•
Install the drain raising pipes at a right angle to the indoor unit and no more than 300 mm from the unit.
NOTE
•
To ensure no excessive pressure is applied to the included drain hose (3), do not bend or twist when
installing. (This may cause leakage.)

If converging multiple drain pipes, install according to the procedure shown below.
Select converging drain pipes whose gauge is suitable for the operating capacity of the unit.
2. After piping work is finished, check if drainage flows smoothly.
•
Open the water inlet lid, add approximately 1000 cc of water gradually and check drainage flow.
