PIPING AND DRAIN HOSE INSTALLATION
How to remove the drains cap
Clip the drain cap by needle-nose pliers and pull out.
How to fix the drains cap
1) Insert hexagonal wrench (dia. 4mm) in a
center head.
4mm
2) Firmly insert drains cap.
No gap
Do not apply lubricating oil
(refrigerant machine oil)
when inserting the drain cap.
Application causes deterioration
and drain leakage from the plug.
Insert a hexagon wrench (4mm)
CAUTION
Firmly insert the drain hose and drain cap;
otherwise, water may leak.
How to remove the drain hose
1) Remove the front panel.
2) Remove the screws of drain hose.
3) Pull out the drain hose.
How to fix the drain hose
1) Put the drain hose.
2) Screw the drain hose to the indoor unit.
3) Install the front panel.
u In case of right or left piping
• After scribing slits of the front panel with a knife
or a marking-off pin, cut them with a pair of
nippers oran equivalent tool.

u In case of bottom right or bottom left
piping
• After scribing slits of the front panel with a knife
or a marking-off pin, cut them with a pair of
nippers oran equivalent tool.
Slit
u Left-hand connection with piping
Bend the connecting pipe so that it is laid within 43mm above the wall surface. If the connecting pipe is laid
exceeding 43mm above the wall surface, the indoor unit may unstably be set on the wall.
When bending the connecting pipe, make sure to use a spring bender so as not to crush the pipe.
Bend the connection pipe within a radius of 30 mm.

(Use polish polyethylene core or the like for bending pipe.)
Use the handle of screwdriver, etc.
NOTE
If the pipe is bent incorrectly, the indoor unit may unstably be set on the wall.
After passing the connecting pipe through the pipe hole, connect the connecting pipe to the auxiliary pipes and
wrap the facing tape around them.
• Bind the auxiliary pipes (two) and power supply wiring and control wiring with facing tape tightly.
In case of leftward piping and rearleftward piping, bind the auxiliary pipes (two) only with facing tape.
Auxiliary pipes
Installation plate
• Carefully arrange pipes so that any pipe does not stick out of the rear plate of the indoor unit.
• Carefully connect the auxiliary pipes and connecting pipes to one another and cut off the insulating tape wound
on the connecting pipe to avoid double-taping at the joint, moreover, seal the joint with the vinyl tape, etc.
• Since dewing results in a machine trouble, make sure to insulate both the connecting pipes.
(Use polyethylene foam as insulating material.)
• When bending a pipe, carefully do it, not to crush it.
