II. STEP 2 — SELECT LOCATION

Consult local building codes and NEC for special installation
requirements. See Fig. 3 and 4 for unit dimensions and
required clearances.

There are several ways the unit may be installed to different
types of ceiling construction. These instructions do not cover
all installation methods. As a typical installation, these
instructions focus primarily on mounting the unit to metal in

new construction. Plan the installation carefully before you
begin. Listed below are some guidelines that should be fol-
lowed when determining location for the unit.

1. Place unit adjacent to an outside wall if fresh air is

required, ensuring that location allows for complete
air distribution.

2. Locate the thermostat in an area that is not subjected

to drafts or direct sunlight through windows. Locate
the thermostat on an internal wall whenever possible.

3. Allow sufficient clearance for airflow, wiring, refriger-

ant piping, and servicing unit (Fig. 3 and 4).

4. Make sure the unit is easily accessible to electrical

power.
