6. Drainage piping work
1. Connect the drain socket (supplied with the unit) to the drain port. (Fig. 6-2)
(Affix the tube using PVC adhesive then secure it with a band.)
2. Install a locally purchased drain pipe (PVC pipe, O.D. ø32).
(Affix the pipe using PVC adhesive then secure it with a band.)
3. Insulate the tube and pipe. (PVC pipe, O.D. ø32 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.)

7.2. Indoor unit (Fig. 7-2) (Fig. 7-3)
Work procedure
1.Remove 2 screws to detach the electric component cover.
2.Route each cable through the wiring intake into the electric component box. (Pro-
cure power supply cable and indoor/outdoor connecting cable locally.)
3.Securely connect the power supply cable and the indoor/outdoor connecting 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.
• Fix power supply cable and indoor/outdoor connecting cable to electric component
box by using buffer bushing for tensile force. (PG connection or the like.)
Warning:
• Attach the electric component cover securely. If it is attached incorrectly, it
could result in a fire, electric shock due to dust, water, etc.
• Use the specified indoor/outdoor unit connecting cable to connect the in-
door and outdoor units and fix the cable to the terminal block securely so
that no stress is applied to the connecting section of the terminal block. In-
complete connection or fixing of the cable could result in a fire.

• The compressor will not operate unless the power supply phase connection is cor-
rect.
• Grounding protection with a no-fuse breaker (earth leakage breaker [ELB]) is usu-
ally installed for
.
• The connection wiring between the outdoor and indoor units can be extended up to
a maximum of 50 meters.
A switch with at least 3 mm contact separation in each pole shall be provided by the
air conditioner installation.
*Label each breaker according to purpose (heater, unit etc.).
