Installation Of Duct; Wiring Instructions - Field Controls CAS-34U Manual

INSTALLATION OF INTAKE AIR HOOD
After determining the location of the intake air hood, cut a 4
intake air hood and secure with appropriate fasteners. Take precautions to avoid interference with wiring or
other plumbing when cutting the wall opening.

INSTALLATION OF DUCT

Connect the duct pipe from the top of the CAS-34U unit to the Intake Air Hood in the wall. If using 4" diameter
pipe attach the provided 4" x 6" Pipe lncreaser Fitting to the top of the CAS-34U unit. The duct should be
supported with appropriate mounting straps from fl oor joists, walls, or other solid structures. The straps should
be placed so as to keep the ductwork out of passageways. (See Figure 2) A minimum of 12' of pipe should be
run to help temper outside air being drawn in.

WIRING INSTRUCTIONS

Wire the CAS-34U unit in accordance with the National Electrical Code and applicable local codes. THE UNIT
MUST BE GROUNDED. Check the ground circuit to make certain that the unit has been properly grounded. The
wiring should be protected by an over-current circuit device rated at 15 amperes.
CAUTION must be taken to ensure that the wiring does not come in contact with any heat source. All line
voltage and control circuits between the CAS-34U unit and the appliance MUST be wired in accordance
with the National Electrical Code for Class I wiring or equivalent.
Remove the wiring access cover to access the wiring terminals. Use the enclosed conduit connector(s) to route
the appropriate wires through the CAS-34U housing. The incoming ground wire must be attached to the green
colored ground screw near the wire terminals. The following sections describe the most common applications.
The references to various series of control kits implies that any kit in that series may be used.If further information
or additional wiring diagrams are needed please consult Field Controls' technical support.
