Step 1 — 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 (in-
cluding 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 or other sources of contaminated air.
Although unit is weatherproof, avoid locations that permit water
from higher level runoff and overhangs to fall onto unit.
Select a unit mounting system that provides adequate height to al-
low installation of condensate trap per requirements. Refer to Step
10 — Install External Condensate Trap and Line on page 12 for
required trap dimensions.
