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 be-
comes identical.

2.3. Ceiling openings and suspension bolt installation

locations (Fig. 2-3)

• Make an opening in the ceiling 17 in 

×

 37-7/8 in (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.

• 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.
