2.0 – INSTALLATION
2.1 – 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.
2.2 – 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 Fig - 1. For the centre of gravity coordinates, the position of the unit mounting holes,
and the weight distribution points, refer to the Unit Dimensional Drawing.

2. Do not install unit in an indoor location.
2.3 – Inspect Unit
Inspect unit for transportation damage. File any claim with transportation agency. Confirm before installation of unit
that voltage, amperage and circuit protection requirements listed on unit data place agree with power supply
