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 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 at least the minimum clearances re-
quired 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. 3.
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, relief valves, or other sources of
contaminated air.
Although unit 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 require-
ments. Refer to Step 9 — Install External Condensate Trap
and Line for required trap dimensions.
ROOF MOUNT
Check building codes for weight distribution require-
ments. Unit operating weight is shown in Table 2.
Table 2 — Operating Weights
NOTE: Unit not designed to have overhead obstruction. Contact Application Engineering for guidance on any application planning overhead
obstruction or for vertical clearances.
