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

x 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 ma
y result in poor drainage or drain motor failure.
x Do not use drain hose bent at 90° angle. (The maximum permissible bend is 45°.)
