Installation

4-4-10. Drain Hose Installation

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.
1. Remove the rubber cap located on the side of
the base pan depending on the situation.
2. 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.
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.
