Step 10 Installing the drain hose and
drain pipe
1 Push the supplied drain hose as far as possible over
the drain socket.
2 Tighten the metal clamp as shown in the picture.
3 Wrap the supplied large sealing pad over the metal
clamp and drain hose to insulate and fix it with
clamps.
4 Insulate the complete drain piping inside the building
(field supply).
If the drain hose cannot be sufficiently set on a slope,
fit the hose with drain raising piping (field supply).

the drain hose to drain socket.

Install air ventilation to drain condensation smoothly.
Air ventilation
If it is necessary to increase the height of the drain
pipe, install the drain pipe straight within 300 mm
from the drain hose port. If it is raised higher than
550 mm, there may be water leaks.

Do not give the hose an upward gradient beyond
the connection port. This will cause water to flow
backwards when the unit is stopped, resulting in
water leaks.
Under gradient
Do not apply force to the piping on the unit side
when connecting the drain hose. The hose should not
be allowed to hang loose from its connection to the
unit. Fasten the hose to a wall, frame or other support
as close to the unit as possible.
