(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) In the case of the standard series: Cut and opening of
860 ~
890.
In cutting an operating on the ceiling, use the unit’s cardboard container for shipment as a reference of the size of opening.
• The center of the opening on the ceiling must accord with the center of the unit.
2) Determine the positions of suspension bolts (675
×
780).
3) Use four suspension bolts, each fastened in such a manner that it can withstand pull force of 50 kgf.
4) Make suspension bolts to the length that leaves approximately 70 mm of them above the ceiling.
5) After hoisting in the unit, attach level gauges supplied as accessories and determine the unit position (height).
6) Use a transparent tube with water filled inside to check the level of the unit. (A tolerable height difference at an end of
the unit is within 3 mm)
(ii) When embedded into ceiling
1) Determine the positions of suspension bolts (675
×
780).
• 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) In cutting an opening on the ceiling, use the unit’s cardboad container for shipment as a reference of the size of opening.
4) Fix the unit as per (i)-5) and 6) above.
• The unit’s cardboard container for shipment can be used to cover the indoor unit.
Note (1) When a hanging 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.
3) Care must be taken so as not to allow an adhesive to run into the drain hose.
When it is hardened, it can cause a breakage of a fl exible part, if the fl exible
part receives stress.
4) Use VP-25 general-purpose hard PVC pipes for drain piping.
5) Insert the drain hose supplied as an accessory (soft PVC end) to the stepped
part of the unit’s drain socket and then fasten it with the clamp also supplied
as an accessory.
6) Adhesive must not be used.
a) Glue a VP-25 joint (to be procured locally) to joint it with the drain hose
(hard PVC end) and then glue a VP-25 (to be procured locally) to the
joint.
