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. 4

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.
