Connection of drain pipe
• Connect the hard socket (local supply) to the
hard socket side of the attached flexible hose
which has been installed.
• Connect the drain pipes (local supply)
successively to the connected the hard socket.
REQUIREMENT
• Using adhesive agent for vinyl chloride,
connect the hard vinyl chloride pipes certainly
so that water does not leak.
• It requires several times to dry and harden the
adhesive agent.
(Refer to Guide Manual of the adhesive agent.)
In this time, be sure not to apply force to the
connecting section with the drain pipes.
Drain up
When a downward grading cannot be secured on
the drain pipe, a drain-up work is possible.
• Set the height of the drain pipe within 850mm
from the bottom surface of the indoor unit.
• Draw out the drain pipe within 300mm from the
end of the drain pipe connecting port of the
indoor unit, and then raise it vertically.
• After the drain pipe has been raised, set a
grading so that it is immediately bent
downward.

Check the draining
After drain piping work, check that water drain is
properly performed and water does not leak from
the connecting part of the pipes. In this time,
check also there is no abnormal sound of the
motor of the drain pump. Be sure to check draining
when installed in the heating period.
When the electric work has finished:
• Pour water as shown in the following figure,
check water is drained from the drain pipe
connecting port in COOL mode, and then check
there is no water leak from the drain pipes.
CAUTION
Pour water slowly.
If it is poured urgently, water is spread inside of
the indoor unit resulted in a trouble.
Insert the edge of hose
into the drain pan and
bend it downward.
Pump
Vessel
• If the electric work has not yet finished, pull out
the float switch connector (CN34 : Red) from the
electric parts box, and check draining by
plugging the single phase 220–240V power to
the terminal blocks ➀ and ➁.
If doing so, the drain pump motor operates.
• Test water drain while checking the operation
sound of the drain pump motor.
(If the operation sound changes from
continuous sound to intermittent sound, water is
normally drained.)
