.INSTALLATION
Jobsite Survey
Complete the following checks before installation.
1. Consult local building codes and the NEC (Nati onal
Electrical Code) ANSI/NFPA 70 for special installa-
tion requirements.
2. Determine unit location (from project plans) or select
unit locati on.
3. Check for possible overhead obstructions whic h may
interfere with unit lifting or rigging.
Step 1 — Plan for Unit Location
Selec t a location for the unit and its support system (pad,
rails or other) that provides for the m inimum c leara nces
required for safety. This includes the c learance to
combustible surfaces, unit performance and service access
below, around and above unit as specified in unit
drawings. See Fig. 4.
Selec t a unit mounting system that provides adequate
height to allow for removal and disposal of frost and ice
that will form during the hea ting-defrost m ode.
NOTE: Consider also the effect of adjacent units on
airflow performance and control box safety clearance.
