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 and Fig. 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.
