connection port. This will cause water to ow backwards
when the unit is stopped, resulting in water leaks.
Under 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
