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.

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.
