DRAIN PIPING WORK
Rig the drain piping as shown in figure and take measures
against condensation. Improperly rigged piping could lead to
leaks and eventually wet furniture and belongings.

Hanging bar
1. Install the drain pipes.
•
Keep piping as short as possible and slope it downwards
so that air may not remain trapped inside the pipe.
•
Keep pipe size equal to or greater than that of the
connecting pipe (Vinyl pipe of 25mm nominal diameter and
32mm outer diameter).
•
Insert the supplied drain hose into the drain socket, up to
the white tape.
•
Tighten the clamp until the screw head is less then 4mm
from the hose.

•
Insulate the drain hose inside the building.
•
If the drain hose cannot be sufficiently set on a slope, fit
the hose with drain raising piping (field supply).
HOW TO PERFORM PIPING (see figure 8)

Clamp metal (supplied with the unit)
1 Connect the drain hose to the drain raising pipes, and insulate
them.
2 Connect the drain hose to the drain outlet on the indoor unit,
and tighten it with the clamp.
PRECAUTIONS
•
Instal the drain raising pipes at a height of less than 310mm.
•
Install the drain raising pipes at a right angle to the indoor unit
and no more than 300mm from the unit.
NOTE
•
The incline of attached drain hose should be 75mm or less
so that the drain socket does not have to stand additional
force.
•
To ensure a downward slope of 1:100, install hanging bars
every 1 to 1.5m.
•
If unifying multiple drain pipes, install the pipes as shown
in figure 9. Select converging drain pipes whose gauge is
suitable for the operating capacity of the unit.

2. After piping work is finished, check if drainage flows
smoothly.
•
Open the water inlet lid, add approximately 2.5l of water
gradually and check the drainage flow.
Method of adding water. See figure 10.

If adding water from the charge inlet at the fan casing, be
sure to put the lid back in its original position.
WHEN ELECTRIC WIRING WORK IS FINISHED
Check drainage flow during COOL running, explained in chapter
"TEST OPERATION".
WHEN ELECTRIC WIRING WORK IS NOT FINISHED
•
Remove the switch box lid and connect the power supply and
remote controller to the terminals.
See figure 11.

Next, press the inspection/test operation button
TEST
on the
remote controller. The unit will engage the test operation
mode. Press the operation mode selector button
until
selecting fan operation
. Then, press the on/off button
.
The indoor unit fan and drain pump will start up. Check that
the water has drained from the unit. Press
TEST
to go back to
the first mode.
•
You can check whether drainage is satisfactory or not by
removing the access opening lid and checking the water level
of the drain pan through the access opening.
Be careful
when doing so because the fan is turning at the same
time.
See figure 12.
