Installing the indoor unit
• The recommended installation method is back piping.
•
When performing bottom piping or left side piping, refer to “3-2. Left-side, left-back, or left-bottom piping”.
• Right side piping cannot be performed.
• In the case of bending or curing refrigerant pipes, keep the following precautions in mind.
Abnormal sound may be generated if improper work is conducted.
• Do not strongly press the refrigerant pipes onto the bottom frame.
• Do not strongly press the refrigerant pipes on the front grille, either.
3-1. Right-back or right-bottom piping
1) Attach the drain hose to the underside of the
refrigerant pipes with adhesive vinyl tape.
2) Wrap the refrigerant pipes and drain hose
together with
insulation tape.
3) Pass the drain hose and refrigerant pipes
through the wall hole, then position the indoor
unit on the
mounting plate hooks, using the
markings at the top of the indoor unit as a
guide.
3-2. Left-side, left-back, or left-bottom piping
1) Switch around the drain plug and drain hose.
2) Attach the drain hose to the underside of the refrigerant
pipes with adhesive vinyl tape.
3) Shape the refrigerant pipes along the pipe path marking
on the
mounting plate.
How to remove the pipe port cover
1) Cut off the pipe port cover (on the bottom of the
front grille) with a copping saw.
Apply the blade of the copping saw to the notch,
and cut off the pipe port cover along the uneven
inner surface.
2) After cutting off the pipe port cover, perform filing.
Remove the burrs along the cut section using a half
round needle file.
NOTE
• Be careful not to let chips enter the driving section of the arm.
• Be careful not to put pressure on the lower front panel.

How to switch around the drain plug and drain hose
2) Pull out
drain plug.
Push the drain plug all the
way in using a hexagonal
wrench (3/16 inch (4mm)).

Do not apply lubricating oil
(refrigerant oil) to the drain
plug when inserting it.
The application of lubrication
oil to the drain plug will
deteriorate the plug to cause
drain leakage from the plug.
Insert a hexagonal
wrench (3/16 inch (4mm)).
Insert drain hose securely
and fix in place with fixing
screw.
