Connecting Drain Pipe - Toshiba RAV-RM301SDT-E Installationsanleitung

 Connecting drain pipe
• Connect the hard socket (Locally procured) to the hard
socket side of the attached flexible hose which has been
installed.
• Connect the drain pipes (Locally procured) 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.

• If the electric work has not yet finished, pull out the float
switch connector (CN34 : Red) from the electrical control
box, and check draining by plugging the single phase 220
– 240 V 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.)

• After the check, the drain pump motor runs, connecting the
float switch connector.
(In case of check by pulling out the float switch connector,
be sure to return the connector to the original position.)

 Heat insulating
• After drain check, using the attached heat insulator for
drain connecting section, wrap the flexible hose without
clearance from the end of the drain pipe connecting port of
the indoor unit.
• Covering the attached heat insulator for drain connecting
section, wrap the drain pipe with heat insulator (Locally
procured) without clearance.
