Positioning

Maintain clearance around and above unit to provide minimum distance from combustible materials, proper airflow, and service access. (See Fig. 7, 8 and 9.)

Position unit on roof curb so that the following clearances are maintained: 1/4-in. clearance between the roof curb and the base rail inside the front and rear, 0.0 in. clearance between the roof curb and the base rail inside on the duct end of the unit. This will result in the distance between the roof curb and the base rail inside on the condenser end of the unit being approximately equal to Fig. 2, section C-C.

Do not install unit in an indoor location. Do not locate unit air inlets near exhaust vents or other sources of contaminated air.

NOTE: Trap should be deep enough to offset maximum unit static difference. A 4-in. trap is recommended.

Fig. 5 ---Condensate Drain Piping Details

Although unit is weatherproof, guard against water from higher level runoff and overhangs.

After unit is in position, remove polyethylene shipping wrapper and top crating.
