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).
5
Push the drain hose up to insulation when connecting
the drain hose to drain socket.

• 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.

when the unit is stopped, resulting in water leaks.

• 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.
