Drain Hose Installation
Duct Type
Care must be taken when installing the drain hose for the indoor unit to ensure that any condensate water is
correctly drained outside. The drain hose can be installed to the right or left side of the base pan.
Œ
Remove the rubber cap located on the side of the base pan depending on
the situation.
´
Install the drain hose so that its length can be as short as possible.
Internal diameter of the drain hose should be the same or slightly bigger
than the external diameter.
- Give a slightly slant to the drain hose for proper drainage of
Note
condensate.
- Secure the drain hose with the cable-tie not to be separated from
the unit.
ˇ
Wrap the drain hose with the insulation drain pipe, the insulation drain A as
shown in figure and secure them. And wrap the other drain tube outlet with
the insulation drain B provided.
CAUTION
When not installing the drain pump
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.
Upward 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.
