(c) Suspension
• Please arrange four sets of a suspension bolt (M10 or M8), a nut matching the bolt, a fl at washers and a spring washer on the
installation site.
(i)
When suspension from the ceiling
1) This unit is designed for installation on a 2 × 2 grid ceiling.
If necessary, please detach the T bar temporarily before you install it.
When it is installed on a ceiling other than 2 × 2 grid ceiling, please do not fail to provide an inspection port on
the control box side.
2) Determine the positions of suspension bolts (530 × 530).
3) Use four suspension bolts, each fastened in such a manner that it can withstand pull force of 50kgf.
4) Make suspension bolts to the length that leaves approximately 45mm of them above the ceiling. In hoisting the unit
main body in, temporarily fasten the four lower nuts of the suspension bolts approx. 93 mm from the ceiling and the
four upper nuts at positions sufficiently far from the lower nuts so that they may not hamper installation work when the
unit is hoisted in or the height is adjusted.
7) Please make sure that the unit main body is installed levelly. Level must be checked with a level or
a clear hose filled with water. (A tolerable height difference at an end of the unit is eithin 3 mm)
8) After you have adjusted the height and level of the unit, fasten the four upper nuts to fi x the unit.
Note (1) Do not adjust the height with the upper nuts. It may cause deformation due to excessive force working on the unit main body, which can result
in such problems that you cannot attach the panel or noises are generated from the interfering fan.
(ii)
When embedded into ceiling
1) Determine the positions of hanging bolts (530 × 530).
• The pitch center of a suspension bolt must accord with the center of the unit.
2) Use four suspension bolts, each fastened in such a manner that it can withstand pull force of 50 kgf.
3) Fix the unit as per (i) 6) and 8) above.
Note (1): When a suspension bolt exceeds 1.3 m in length, use an M10 bolt and give it reinforcements such as braces.
1) Glue the drain hose supplied as an accessory and a VP-25 joint before lifting
the unit.
2) The drain hose is to provide a buffer to absorb a slight dislocation of the unit
or the drain piping during installation work. If it is subject to abuse such as
being bent or pulled deliberately, it may break, which will result in a water
leak.

Piping
5)
Put in the unit on an angle.
6)
After hoisting in the unit, attach level gauges supplied as acces-
sories and determine the unit position (height). To adjust height,
use the four lower nuts with the four upper nuts left loose. Please
make sure that the unit’s four hanging fixtures touch the four
lower nuts and washers evenly without any play.
