Installation Procedure
• Do not give the hose an upward gradient beyond
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.
