3-3. Placing the Unit Inside the Ceiling
This unit is equipped with the drain pump. Check a tape
measure or carpenter’s level.
Before installing the ceiling panel, complete the work of
drain pipe and refrigerant pipe installation.
(1) When placing the unit inside the ceiling, determine the
pitch of the suspension bolts using the supplied full-scale
installation diagram. (Fig. 3-4)
Tubing and wiring must be laid inside the ceiling when
suspending the unit. If the ceiling is already constructed,
lay the tubing and wiring into position for connection to
the unit before placing the unit inside the ceiling.
(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. 3-4.
(3) Thread the 3 hexagonal nuts and 2 washers (field
supply) onto each of the 4 suspension bolts as shown in
Fig. 3-5. 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.
