INSTALLATION

Jobsite Survey
Complete the following checks before installation.
1. Consult local building codes or the U.S.A. National
Electrical Code (Ref: ANSI/NFPA 70, [American
National Standards Institute/National Fire Protection
Association], latest revision) for special installation
requirements.
2. Determine unit location (from project plans) or select
unit location.
3. Check for possible overhead obstructions which may
interfere with unit lifting or rigging.
Step 1 — Plan for Unit Location
Select a location for the unit and its support system (curb
or other) that provides for the minimum clearances
required for safety. This includes the clearance to
combustible surfaces, unit performance and service access
below, around and above unit as specified in unit
drawings. See Fig. 3.
NOTE: Consider also the effect of adjacent units.
Unit may be installed directly on wood flooring or on
approved roof- - covering material when roof curb is used.
Do not install unit in an indoor location. Do not locate air
inlets near exhaust vents or other sources of contaminated
air.
