2.2. Service space (Fig. 2-2)

• The dimensions of ceiling opening can be regulated within the range shown in

following diagram; so center the main unit against the opening of ceiling, ensuring
that the respective opposite sides on all sides of the clearance between them be­comes identical.

A Air intake
B Air outlet
C Ceiling panel
D Min. 200 mm
E Suspension bolts W3/8 or M10
F Grille

2.3. Ceiling openings and suspension bolt installation

locations (Fig. 2-3)

• Make an opening in the ceiling 430 mm × 960 mm in size. This functions as a check

window and will be needed later during servicing.

• If the dimensions are not accurate, when the grille is installed there may be gaps

between it and the indoor unit. This may result in dripping water or other problems.

• When deciding on placement, consider carefully the space around the ceiling and

make your measurements generous.

• Ceiling types and building construction differ. Therefore you should consult with the

builder and decorator.

A The centers of the ceiling opening and the indoor unit should be aligned.

1 Outer side of grille
2 Ceiling opening
3 Bolt pitch
4 Electric box

• Using the installation template (top of the package) and the gauge (supplied as an

accessory with the grille), make an opening in the ceiling so that the main unit can
be installed as shown in the diagram. (The method for using the template and the
gauge are shown.)

• Use M10 (3/8") suspension bolts.

* Suspension bolts are to be procured at the field.

• After suspending the indoor unit, you will have to connect the pipes and wiring

above the ceiling. Once the location has been fixed and the direction of the pipes
has been determined, place the refrigerant and drainage pipes, the wiring for the
remote controller, and the wiring that connects the indoor and outdoor units in their
desired locations before suspending the indoor unit. This is especially important in
cases where the ceiling is already in existence.

1 Wooden structures (Fig. 2-4)

• Use tie beams (single storied houses) or second floor beams (two story houses) as

reinforcing members.

• Wooden beams for suspending air conditioners must be sturdy and their sides

must be at least 6 cm long if the beams are separated by not more than 90 cm and
their sides must be at least 9 cm long if the beams are separated by as much as
180 cm. The size of the suspension bolts should be ø10 mm (3/8"). (The bolts do
not come with the unit.)

• Use channel, duct and other parts procured locally to suspend the indoor unit.

2 Ferro-concrete structures (Fig. 2-5)
Secure the suspension bolts using the method shown, or use steel or wooden hang­ers, etc. to install the suspension bolts.

D Ceiling panel
E Rafter
F Beam
G Roof beam
H Use inserts rated at 100-150 kg each (pro-

cure locally)

I Suspension bolts M10 (3/8") (procure lo-

cally)

J Steel reinforcing rod
K C channel
L Channel suspension bracket
M M10 suspension bolt

2.4. Unit suspension procedures (Fig. 2-6)

Procure 3/8" bolts or M10 bolts locally.

• Adjust the length of the bolt’s protrusion from the ceiling surface beforehand.

*1. When using an extra upper nut in suspending the unit, in some cases you may

have to add it later.
