all the way into the pipe connections inside the unit.
Exposed piping may cause condensation, or may
cause burns when touched.
Make sure that no oil remains on plastic parts of the
decoration panel (optional equipment).
Oil may cause degradation and damage to plastic
parts.

4.2 Install the drain pipes.
Keep piping as short as possible, and slope it downwards at
a gradient of at least 1/100 so that air may not remain
trapped inside the pipe.
Keep pipe size equal to or greater than that of the connecting
pipe (PVC pipe, nominal diameter 20mm/0.8in in, outside
diameter 25mm/1in).
- Push the drain hose as far as possible over the drain socket,
and tighten the metal clamp securely.

Insulation (field supply)
- Insulate the drain hose inside the building.
- If the drain hose cannot be sufficiently set on a slope, fit the
hose with d ain raising piping (field supply).
「
- Make sure that heat insulation work is executed on the
following 2 spots to prevent any possible water leakage due
to dew condensation.
1 Indoor drain pipe.
2 Drain socket.
