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
between the curb and the end base rails should be
(13 mm). For retrofit
CRRFCURB003A01 and 4A01, the unit should be positioned
as shown in Fig. 7. Maintain the 15
8 5 / -in. (220 mm) clearances and allow the 22
8
(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
wards the end of the unit. (See Fig. 8.)
Although unit is weatherproof, guard against water from
higher level runoff and overhangs.
PLACE ALL SEAL STRIP IN PLACE BEFORE PLACING

IMPORTANT: If the unit has the factory-installed Thru-
the-Base option, make sure to complete installation of the
option before placing the unit on the roof curb. See the fol-
lowing section:
• Factory-Option Thru-Base Connections on page 20
NOTE: If electrical connections are not going to occur at this
time, tape or otherwise cover the fittings so that moisture does
not get into the building or conduit in the interim.
Remove all shipping materials and top skid. Remove extra
center post from the condenser end of the unit so that the con-
denser end of the unit matches Fig. 20-22. Recycle or dispose
of all shipping materials.
