(2) The length of suspension bolts must be appropriate for a
distance between the bottom of the bolt and the bottom
of the unit of more than 18 mm as shown in Fig. 3-88.
(3) Thread the 3 hexagonal nuts and 2 washers (field
supply) onto each of the 4 suspension bolts as shown in
Fig. 3-89. Use 1 nut and 1 washer for the upper side, and
2 nuts and 1 washer for the lower side, so that the unit
will not fall off the suspension lugs.
(4) Adjust so that the distance between the unit and the
ceiling bottom is 12 to 17 mm. Tighten the nuts on the
upper side and lower side of the suspension lug.
(5) Remove the protective polyethylene used to protect the
fan parts during transport.
(6) Check with a tape measure or carpenter's level.

3-36. Installing the Drain Pipe
3-36-1. Before Performing the Installation Drain Piping
(1) Limitations of Raising the Drain Pipe Connection
CAUTION
●
The drain pipe can be raised to a maximum height of
850 mm from the bottom surface of the ceiling.
Do not attempt to raise it higher than 850 mm.
Doing so will result in water leakage. (Fig. 3-90)
(2) Limitations of Drain Pipe Connection
CAUTION
●
Do not install the drain pipe with an upward gradient from
the drain port connection. This will cause the drain water
to flow backward and leak when the unit is not operating.
(Fig. 3-91)
●
Do not install an air bleeder as this may cause water to
spray from the drain pipe outlet. (Fig. 3-91)
●
Do not provide U-trap or bell-shaped trap in the middle of
the drain pipe. Doing so will cause abnormal sound.
(Fig. 3-91)
●
Make sure the drain pipe has a downward gradient (1/100
or more; downward from drain port connection).
(Fig. 3-92)
(3) Limitations of Drain Hose Connection
CAUTION
●
Do not bend the supplied drain hose 90° or more.
Bend it less than 45°. (Fig. 3-93)
●
Do not make a trap in the middle of the supplied drain
hose. Doing so will cause abnormal sound. (Fig. 3-94)
