Fig. 6 — Rigging Details
Step 6 — Rig and Place Unit
Keep unit upright and do not drop. Spreader bars are not re
-
quired.
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 information.
Lifting holes are provided in base rails as shown in Fig. 6. Re
-
fer 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
setting 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
allow 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 12-1/2 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 cen
-
ter post from the condenser end of the unit so that the condens
-
er end of the unit matches Fig. 16 and 17. Recycle or dispose of
all shipping 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.
