5. Run refrigerant piping as directly as possible and avoid

any unnecessary turns or bends.

6. Condensate piping can be directed through the inside

wall to an approved drain or straight outside.

NOTE: The piping hole for condensate line must slope at a

minimum pitch of

in. per foot to ensure proper drainage. If

proper pitch cannot be achieved, install accessory condensate

pump at this time.

Step 3 — Mount Unit —

Refer to Fig. 4 for clearances

and dimensions. Use mounting template included inside box to

locate mounting bolt holes, piping holes, electrical connec-

tions, and accessory outdoor-air intake, if used.

Select proper type of hardware from the guidelines below.

See Fig. 5.

WOODEN

STRUCTURE

—

Install hanging bolts on a

square wooden piece placed over beams.
NEWLY BUILT CONCRETE SLAB — Install hanging bolts

with inserts, embedded bolts, etc.
METAL STRUCTURE — Install hanging bolts utilizing an

existing angle or by installing a new support angle.
PREVIOUSLY BUILT CONCRETE SLAB — Install hang-

ing bolts with expansion anchor.
TO MOUNT UNIT:

1. Remove mounting bracket and reinstall the 2 hex-head

bolts (factory-supplied) into each side of indoor unit as

shown in Fig. 6. Allow approximately

-in. space

between bolt head and unit.

2. Determine installation position, paying particular

attention to piping lengths, wiring connections, clear-

ances, etc. See Fig. 3 for connection locations, Fig. 4

for clearances, and Fig. 7 and 8 for bolt locations.

3. Open knockout if right-side piping connections are

required (Fig. 9), by removing the pre-slit portion in

the rear of the right side panel with a saw or cutter

knife.

4. Mount hanging brackets on ceiling (Fig. 10) for either

concealed or exposed bolt hanging position.

5. Lift the unit into place, and fit the hex-head bolts on

sides of indoor unit into mounting slots of mounting

brackets (Fig. 11). Ensure unit is mounted with a slight

tilt to the right rear side for properly drainage.

6. Tighten indoor unit hex-head bolts securely.

Solid structure in ceiling must be used due to the weight of

the unit.
