Positioning on Curb —

For full perimeter curbs CRRFCURB072A00 and 073A00, 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. 6. 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. 6 - 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.

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. 16 - 18. Recycle or dispose of all shipping materials.

Step 7 — Convert to Horizontal and Connect Ductwork (when required)

Unit is shipped in the vertical duct configuration. Unit without factory-installed economizer or return air smoke detector option may be field-converted to horizontal

ducted configuration using accessory CRDUCTCV001A00. To convert to horizontal configuration, remove screws from side duct opening covers and remove covers.

Discard the supply duct cover. Install accessory CRDUCTCV001A00 to cover the vertical supply duct opening. Use the return duct cover removed from the end panel to cover the vertical return duct opening.

Field-supplied flanges should be attached to horizontal duct openings and all ductwork should be secured to the flanges. Insulate and weatherproof all external ductwork, joints, and roof or building openings with counter flashing and mastic in accordance with applicable codes.

Do not cover or obscure visibility to the unit’s informative data plate when insulating horizontal ductwork.

Step 8 — Install Outside Air Hood

Economizer Hood Removal and Setup -

Factory Option —

1.The hood is shipped in knock-down form and located in the return air compartment. It is attached to the economizer using two plastic tie-wraps.

2.To gain access to the hood, remove the filter access panel. (See Fig. 8.)

3.Locate and cut the (2) plastic tie-wraps, being careful to not damage any wiring. (See Fig. 9.)

4.Carefully lift the hood assembly through the filter access opening and assemble per the steps outlined in Economizer Hood and Two–Position Hood on page 10.
