INSTALLATION

Step 1 — Check Equipment and Jobsite

UNPACK UNIT — Move to final location. Slide

from carton taking special care not to damage serv

ice valves or grilles.

INSPECT EQUIPMENT — File claim with ship

ping company if damaged or incomplete.

COMPLETE OR CONSIDER SYSTEM RE

QUIREMENTS before installation:

Consult local building codes and National Elec

trical Code (NEC) for special installation

requirements.

When installing, allow sufficient space for airflow

clearance, wiring, refrigerant piping and service.

Maintain a minimum of 4 ft clearance from obstruc

tions above and 18 in. on sides of unit. Maintain a

distance of 24 in. between condensing units. Posi

tion so water from roof or eaves does not flow

directly on unit.

Install on a solid, level mounting pad. It is not

necessary to attach unit to pad but if desired or

required by local code, position tiedown bolts in

pad. Fasten unit to pad using 2 holes provided in unit

base. See Fig. 1.
