Step 4 —Rig and Place Unit
Inspect unit for transportation damage, and file any claim with transportation agency. Keep unit upright and do not drop. Spreader bars are not required if top crating is left on unit, and rollers may be used to move unit across a roof. Level by using unit frame as a reference. See Table 1, 2 and Fig. 6 for additional information. Operating weight is shown in Table 1, 2 and Fig. 6.
Lifting holes are provided in base rails as shown in Fig. 7. Refer to rigging instructions on unit.

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

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.
