3.4. Drainage piping work (Fig. 3-4)
• 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.

1. Connect the drain socket (supplied with the unit) to the drain port. (Fig. 3-5)
(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
(inch)
band. (Both insulating material and band are supplied with the unit.)

1. Loosen the two screws securing the electric component cover, and then slide and
remove the cover.
2. Route each cable through the wiring intake into the electric component box. (Procure
power supply cable and control cable locally.)
3. Securely connect the power supply cable and control cable to the terminal
blocks.
4. Secure the wires with the cable straps inside the electric component box. Secure
the wires with cable straps as cushioning components so that no stress is applied
to the connecting sections of the terminal block when tension is generated.
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 (1/16 inch))
• 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.
