Drainpipe and drain hose installation
Care must be taken when installing the drainpipe and drain hose for the indoor unit so that condensate water is drained
correctly outside.
1. Fix the flexible hose to the drainpipe.
f The connection port of the flexible hose and PVC drainpipe must be
f
fixed with PVC adhesives.
f Check out that the connected part doesn't leak.
f
f Drain pipe type : VP20(MH✴✴✴FSBA), VP25(MH✴✴✴FMBA)
f
2. Connect the flexible hose to the flexible hose port.
f Make sure that a rubber ring is installed on the drain hose port.
f
3. Install the drainpipe as shortly as possible.
f Give a slightly slant to the drainpipe for proper drainage of condensate
f
water.
f There must be no gap on the connected part so that the drainpipe is
f
not separated from the flexible hose.
4. Insulate the drainpipe, and then fix it as indicated.
Check that the indoor unit is level with the ceiling by using the leveler.
CAUTION
• Install air ventilation to drain condensate water smoothly.
• 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.

• If it is necessary to increase the height of the drainpipe,
install the drainpipe straightly within 300mm(11.81")
from the drain hose port. If it is raised higher than
550mm(21.65"), there can be 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.
