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

Check that the indoor unit is level with the ceiling by using the leveler.
Do not give the hose and upward gradient after the
connection port. This will cause water to flow backwards
when the unit is stopped, resulting in water leaks.
Air ventilation
Ceiling
Install air ventilation to drain condensate water smoothly.
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.

If it is necessary to increase the height of the drainpipe,
install the drainpipe straightly within 300 mm from the
drain hose port. If it is raised higher than 550 mm, there
can be water leaks.
