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 1/4 in. per foot to ensure proper drainage. If proper pitch cannot be achieved, install accessory conden- sate pump at this time.

III. 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 connections, and accessory outdoor- air intake, if used.

Select proper type of hardware from the guidelines below. See Fig. 5.

CAUTION: Solid structure in ceiling must be used due to the weight of the unit.

A. Wooden Structure

Install hanging bolts on a square wooden piece placed over beams.

B. Newly Built Concrete Slab

Install hanging bolts with inserts, embedded bolts, etc.

C. Metal Structure

Install hanging bolts utilizing an existing angle or by install- ing a new support angle.

D. Previously Built Concrete Slab

Install hanging bolts with expansion anchor.

E. 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 3/8-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 proper drainage.

6.Tighten indoor unit hex-head bolts securely.
