INSTALLATION

Jobsite Survey
Complete the following checks before installation.
1. Consult local building codes and the NEC (National Elec-
trical Code) (ANSI/NFPA 70) 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 minimum clearances required for safe-
ty (including clearance to combustible surfaces), unit perfor-
mance and service access below and around unit as specified in
Fig. 3.

Recommended service clearance
Minimum clearance
Surface behind servicer is grounded (e.g., metal, masonry wall)
Surface behind servicer is electrically non-conductive (e.g., wood, fiberglass)
Check sources of flue products within 10 ft of unit fresh air intake hood
Side condensate drain is used
Minimum clearance
Surface behind servicer is grounded (e.g., metal, masonry wall, another unit)
Surface behind servicer is electrically non-conductive (e.g., wood, fiberglass)
NOTE: Consider also the effect of adjacent units.
Unit may be installed directly on wood flooring or on Class 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 unit is weatherproof, avoid locations that permit wa-
ter 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.
Refer to "Step 9 — Install External Condensate Trap and Line"
on page 12 for required trap dimensions.
