3.1. Drainage piping work (Fig. 3-1)
• The indoor parts of the drain pipe should be wrapped with polyethylene foam
insulation materials (specific gravity of 0.03, thickness of 9 mm or more).
• Use VP25 (O.D. ø32 PVC TUBE) for drain piping and provide 1/100 or more
downward slope.
• Be sure to connect the piping joints using a PVC type adhesive.
• Observe the figure for piping work.
• Use the included drain hose to change the extraction direction.
• When performing the drainage piping work, be sure to use the support metal hold-
ers.
If a load is applied to the drain socket that damages the hose or causes the hose
to become detached, water leakage may result.

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