6-36. 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. 1-122)
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 45/64” (18 mm) as shown in Fig. 1-122.
(3) Thread the 3 hexagonal nuts and 2 washers (field supply)
onto each of the 4 suspension bolts as shown in Fig. 1-123.
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 15/32” (12 mm) ~ 43/64” (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.

6-38. Installing the Drain Pipe
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
2.79 ft. (850 mm) from the bottom surface of the ceiling.
Do not attempt to raise it higher than 2.79 ft. (850 mm).
Doing so will result in water leakage. (Fig. 1-124)
(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. 1-125)
Do not install an air bleeder as this may cause water to spray
from the drain pipe outlet. (Fig. 1-125)
Do not provide U-trap or bell-shaped trap in the middle of the
drain pipe. Doing so will cause abnormal sound.
(Fig. 1-125)
Make sure the drain pipe has a downward gradient (1/100 or
more; downward from drain port connection).
(Fig. 1-126)
(3) Limitations of Drain Hose Connection
CAUTION
Do not bend the supplied drain hose 90° or more.
Bend it less than 45°. (Fig. 1-127)
Do not make a trap in the middle of the supplied drain hose.
Doing so will cause abnormal sound. (Fig. 1-128)
