Use P25 (O.D. ø32 (1-1 4”) P C TUBE) for drain piping and provide 1 1 or
more downward slope.
Be sure to connect the piping oints using a polyvinyl type adhesive.
Observe the gure 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. 3-2)
(Fix the tube using P C adhesive then secure it with a band.)
2. Install a locally purchased drain pipe (P C pipe, O.D. ø32).
(Fix the pipe using P C adhesive then secure it with a band.)
3. Insulate the tube and pipe. (P C pipe, O.D. ø32 and socket)
4. Check that drain ows 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.)

Unit suspension procedures (Fig
2-
)
Suspend the main unit as shown in the diagram.
Figures given in parentheses represent the dimensions in case of installing optional
multi function casement.
1. In advance, set the parts onto the suspension bolts in the order of the washers
(with insulation), washers (without insulation) and nuts (double).
Fit the washer with cushion so that the insulation faces downward.
In case of using upper washers to suspend the main unit, the lower washers (with
insulation) and nuts (double) are to be set later.
2. Lift the unit to the proper height of the suspension bolts to insert the mounting
plate between washers and then fasten it securely.
3. When the main unit can not be aligned against the mounting hole on the ceiling,
it is ad ustable owing to a slot provided on the mounting plate.
Make sure that A is performed within 17-22 mm. Damage could result by failing to
adhere to this range. (Fig. 2-6)

Using the gauge attached to the grille, ensure that the bottom of the main unit is
properly aligned with the opening of the ceiling. Be sure to con rm this, otherwise
condensation may form and drip due to air leakage, etc.
Con rm that the main unit is horizontally levelled, using a level or a vinyl tube lled
with water.
After checking the position of the main unit, tighten the nuts of the suspension bolts
securely to fasten the main unit.
The installation template (top of the package) can be used as a protective sheet
to prevent dust from entering the main unit when the grilles are left unattached for
a while or when the ceiling materials are to be lined after installation of the unit is
nished.
* As for the details of tting, refer to the instructions given on the Installation template.
