• Use VP25 (O. D. ø32 mm, 1-1/4 inch PVC TUBE) for drain piping and provide
1/100 or more downward slope.
• Be sure to connect the piping joints using a polyvinyl type adhesive.
• Observe the figure for piping work.
• Use the included drain hose to change the extraction direction.

6. Electrical work
6.1. Indoor unit (Fig. 6-1)
1. Remove 2 screws to detach the electric component cover.
2. Route each cable through the wiring intake into the electric component box.
(Procure power supply cable and control cable locally.)
3. For radio frequency interface
•
Connect the electric cord of radio frequency interface securely to CN105 (RED)
on indoor controller board.
For wired remote controller
• Securely connect the power supply cable and control cable to the terminal
blocks.
4. Secure the cables with clamps outside the electric component box.
5. Attach the electric component cover as it was.
•
Do not allow slackening of the terminal screws.
•
Always install earth.
(Earth cable dia: Thicker than 1.6 mm, 5/8 inch (AWG14))
• Fix power supply cable and control cable to electric component box by using
buffer bushing for tensile force. (PG connection or the like.)
• Tape is affixed over the conduit hole used for connecting the electric wiring.
Please remove this tape if making a connection through the hole.

1. Connect the drain socket (supplied with the unit) to the drain port. (Fig. 5-6)
(Affix the tube using PVC adhesive then secure it with a band.)
2. Install a locally purchased drain pipe (PVC pipe, O.D. ø32 mm, 1-1/4 inch).
(Affix the pipe using PVC adhesive then secure it with a band.)
3. Insulate the tube and pipe. (PVC pipe, O.D. ø32 mm, 1-1/4 inch and socket)
4. Check that drain flows smoothly.
5. Insulate the drain port with insulating material, then secure the material with a
band. (Both insulating material and band are supplied with the unit.)
