Fig. 6 -- Rigging Details
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
retrofit applications with curbs CRRFCURB003A01 and
4A01, the unit should be position as shown in Fig. 7.
Maintain the 15.5 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 12.5 in (320
mm) towards the 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 Figs. 27 and 28.
Recycle or dispose of all shipping materials.
