INSTALLATION
Jobsite Survey
Complete the following checks before installation.
1. Consult local building codes and the NEC (National
Electrical Code) (ANSI/NFPA 70) for special installa-
tion requirements.
2. Determine unit location (from project plans) or select
unit loca tion.
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 provide s for mini mum clearances required
for safety (including clearance to combustible surfaces),
unit performance and service access below and around
unit as specified in Fig. 3.
NOTE: Consider also the effect of adjacent units.
Unit may be installed directly on woo d floor ing or on Clas s
A, B, or C 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 .
Although uni t is weatherproof, avoid locations that permit
water from higher level runoff and overhangs to fall onto
the unit.
Select a unit mounting system that provides adequate height
to allow installation of condensate trap per requirements.
RefertoStep9—InstallExternalCondensate Trap and
Line for required trap dimensions.
