be bolted to standard Carrier 39E Central Station
Air-Handling Unit section without modification.
They may also be installed in field-fabricated duct
systems. Sections are identified as:

If shipment is incomplete, contact Carrier. File
damage claims with transportation agency.
Step 2 — Rig Roll Filter Section — Section is
designed for overhead rigging only. Do not removS
shipping skids until RFS is ready to be moved to
final location. Whenever RFS is moved, use slings
and spreader bars to prevent damage to enclosure
(Fig. 1). Brackets on entering air end of section are
for suspension and are not to be used for rigging.
Refer to base unit installation instructions as
required.
Step 3 — Suspend Roll Filter Section — Sec­
tions are supplied with suspension brackets on air
inlet end of channel leg supports (Fig. 1). Unit sizes
08 thru 57 may be suspended by these brackets and
by downstream component bolted to outlet flange.
Size 90 may not be suspended.
Step 4 — Make Airway Connection — Holes in
RFS flanges match holes in 39E base unit sections.
Assemble sections using fasteners shipped in cloth
bag in RFS. For outdoor installation, apply black
caulking gasket on inlet and outlet flanges. Gasket
is shipped in RFS.
Step 5 — Review RFS Components — Fa­
miliarize installer with RFS interior before proceed­
ing with installation of power wiring and filter media
roll. This simplifies installation and prevents
damage to equipment. Refer to Fig. 2 thru 5.
Step 6 — Install Power and Control Wires —
Junction box is located on right-hand side of RFS
as shown in Fig. 2 and 3. Install a separate field-
supplied power disconnect. On 39ER roof-curbed
units, route wires internally. Install all outdoor
wiring in accordance with local codes. Connect to
pigtails LI and L2 provided. Also connect green
ground wire found in junction box.
