General Mounting - Ceiling Suspended and Convertible Surface

APPLICATION GUIDELINES

1. Prepare four (4) hanging bolts (each bolt length should be the

same length).

2. Select and mark the areas where the hanging bolts and the piping

access holes should be placed on the ceiling.

3. Drill the holes. Add the washers and regular nuts to the hanging

bolts. Insert the anchor nuts into the ceiling, then firmly mount the

suspension bolts to the anchor nuts.

4. Tighten the washers and regular nuts to lock the hanging bolts to

the ceiling.

5. Secure the hangers on the indoor units to the hanging bolts using

nuts, washers, and spring washers.

6. Measure for level. Adjust the angle as necessary by tightening

and / or loosening the hanging bolts.

7. Adjust the slope by tightening and / or loosening the hanging

bolts. The indoor unit should have a slight incline so it will drain

easily. The incline should be less than or equal to 1°, or between

3/8 - 3/4 inch in drain direction.

• Anchor Nut

The threaded rod hangers (bolts) and hardware must be securely tight-

ened to prevent the unit from falling from its installation location. There is

a risk of personal injury from falling equipment.
