Fig. 6 — Rigging Details
Step 6 — Rig and Place Unit
Keep unit upright and do not drop. Spreader bars are not required.
Rollers may be used to move unit across a roof. Level by using
unit frame as a reference. See Table 2 and Fig. 6 for additional in
-
formation.
Lifting holes are provided in base rails as shown in Fig. 6. Refer to
rigging instructions on unit.
Rigging materials under unit (cardboard or wood to prevent base
pan damage) must be removed PRIOR to placing the unit on the
roof curb.
When using the standard side drain connection, ensure the red
plug in the alternate bottom connection is tight. Do this before set
-
ting the unit in place. The red drain pan can be tightened with a
1/2 in. square socket drive extension. For further details see Install
External Condensate Trap and Line on page 11.
Before setting the unit onto the curb, recheck gasketing on curb.
POSITIONING ON CURB
For full perimeter curbs CRRFCURB074A00 and 075A00, the
clearance between the roof curb and the front and rear base
rails should be 1/4 in. (6.4 mm). The clearance between the
curb and the end base rails should be 1/2 in. (13 mm). For ret
-
rofit applications with curbs CRRFCURB003A01 and 4A01,
the unit should be positioned as shown in Fig. 7. Maintain the
15 1/2 in. (394 mm) and 8 5/8 in. (220 mm) clearances and al
-
low the 22 5/16 in. (567 mm) dimension to float if necessary.
Fig. 7 — Retrofit Installation Dimensions
If the alternative condensate drain location through the bottom of
the unit is used in conjunction with a retrofit curb, the hole in the
curb must be moved 12.5 in. (320 mm) towards the duct end of the
unit. See Fig. 8.
Although unit is weatherproof, guard against water from higher
level runoff and overhangs.
Remove all shipping materials and top skid. Remove extra center
post from the condenser end of the unit so that the condenser end
of the unit matches Fig. 17 and 18. Recycle or dispose of all ship
-
ping materials.

NOTES:
1. Dimensions in () are in millimeters.
2. Hook rigging shackles through holes in base rail, as shown in detail “A.” Holes in base rails are centered around the unit center of gravity. Use
wooden top to prevent rigging straps from damaging unit.
CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage.
All panels must be in place when rigging. Unit is not designed
for handling by fork truck when packaging is removed.
If using top crate as spreader bar, once unit is set, carefully
lower wooden crate off building roof top to ground. Ensure
that no people or obstructions are below prior to lowering the
crate.
