6. Drainage piping work
6.1. Drainage piping work (Fig. 6-1)
• Use VP25 (O. D. ø32 PVC TUBE) for drain piping and provide 1/100 or more down-
ward 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.

7. Electrical work
7.1. Indoor unit (Fig. 7-1)
1. Remove the two electrical wiring service panels.
2. Wire the power cable and control cable separately through the respective wiring
entries given in the diagram.
• Do not allow slackening of the terminal screws
• Leave excess cable so that the electrical box can be suspended below the unit
during servicing. (Approx. 50 to 100 mm)

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.)

*1. A breaker with at least 3 mm contact separation in each pole shall be provided. Use non-fuse breaker (NF) or earth leakage breaker (NV).
*2. A 10 m wire is attached in the remote controller accessory.
*3. The figures are NOT always against the ground.
S3 terminal has DC 24 V against S2 terminal. However between S3 and S1, these terminals are not electrically insulataed by the transformer or other device.
Notes: 1. Wiring size must comply with the applicable local and national code.
2. Power supply cords and Indoor unit/Outdoor unit connecting cords shall not be lighter than polychloroprene sheathed flexible cord. (Design 245 IEC 57)
3. Install an earth longer and thicker than other cables.
