11.1.4 Connecting the Drain Piping

Lay the drain piping so as to ensure drainage.

Use a locally purchased VP20 general rigid PVC pipe (outer diameter ø1 1/32" (ø26)) for the drain piping and
firmly connect the indoor unit and the drain piping using supplied hose band to ensure that no leakage
occurs.

Drain piping located indoor should always be insulated by wrapping with locally purchased insulation (foamed
polyethylene with a thickness of 13/32" (10 mm) or more).

The drain piping should have a downward gradient (1/100 or more) and should be secured by using pipe hanging
equipment to avoid creating hills or traps partway.

Should there be any obstacle preventing the drain piping from being extended smoothly, the drain piping can be
raised outside of the main unit as shown in the illustration below.

 Strictly do not install and extend the drain piping from the main unit drain water outlet horizontally or upward or raised it 19 11/16" (500 mm)
or more.
Doing so may result in poor drainage or drain motor failure.
 Do not use drain hose bent at 90° angle. (The maximum permissible bend is 45°.)
