before attempting to install
or operate the heater.
3480/RCH SERIES
GENERALINFORMATION
MOUNT HORIZONTAL POSITION ONLY.
DO NOT INSTALLANY CLOSER THAN 12” TO NEAREST WALL
CHECK TO SEE THAT SERVICE VOLTAGE IS THE SAME AS HEATER VOLTAGE.
ALL WIRING MUST CONFORM TO THE NATIONAL ELECTRIC CODEAND EXISTING LOCAL CODE
REQUIREMENTS.
FORM: 9480
ECO 1-5917
NOTE: If plaster frame is required for installation
order it as an option.
WARNING: To avoid the risk of fire, shock or personal
injury; make sure that the power source is disconnected
before attempting to install, service, clean or disas-
semble the heater or any of its components. If the power
disconnect is out of the line of sight, lock in in the open
position and tag it to prevent the application of power.
INSTALLATION INSTRUCTIONS:
1. Detach heater unit from the ceiling mounting plate
in the recessed can by disengaging the stabilizing
arms on ceiling plate from the heater unit.
4 - #8 drive screws.
2. For a dropped or suspended ceiling, anchor the
recessed can useing either threaded rod, or wire in
an approved method that is sufficient to support
the heater assembly such that the bottom edge of
the recessed can just rest on the T-bar frame. For
plaster or similar finished ceilings, the can should
be installed so the flanges (of the can) are even
with the interior finish or ceiling line.
3. For plaster or other similar finish ceilings attach
the PT3480 accessory plaster frame to the
recessed can using 8 - #8 x 3/4 drive screws.
(detail “AA”)
4. Hang heater unit from two stabilizing arms on the
ceiling mounting plate in the can. Be sure to
engage the two arms with the hooked ends on the
ceiling plate with the slots in the heater plate.
5. Connect the heater leads with their corresponding
supply leads in the outlet box (75OC wire must be
used). The outlet box is permanently attached to
the top of the can. After this is complete, install the
ceiling plate access hole cover with
2 - #8 drive screws which have been provided.
6. Swing the heater unit up to the ceiling mounting
plate and secure with 4 - #8 drive screws that have
been provided. Do this by placing one screw in
each of the four stabilizing arms on the ceiling
plate.
7. Install heater exterior grille by attaching it directly to
the heater unit. Rotate the exterior grille so that the
two 1/4” dia. holes in the exterior grille aligne with
the manual reset limit control located on the bottom
of the venturi of the heater assembly, also make
alignements so that the venturi of the heater
assembly is on the outside the venturi of the
exterior grille. Secure to the four bracket arms on
the heater case with 4 - 10/32 x 3/4 button head
machine screws provided.

THERMAL CUTOUT (480 volt models)
If for any reason temperatures increase beyond normal
limits, safety thermal limit will open de-energizing heat-
ing element and fan motor. Check entire installation to
determine cause of overheating and take corrective
measures. The limit control is the automatic reset type
and after cooling will reset, allowing heater to resume
operation.
CAUTION: To avoid the risk of fire, shock or personal
injury; do not insert or allow any foreign objects or
hands to enter any ventilation or exhaust openings.
THERMAL CUTOUT OPERATION
(WITH ZERO-VOLT RESET)
To reset thermal cutout disconnect all power for 5
minutes then energize unit. If fault continues discon-
nect power and check for causes.
THERMAL CUTOUT OPERATION
(WITH CAPILLARY MANUALRESET)
To reset thermal cutout, first disconnect power from
the unit allowing time to cool, locate the two 1/4” dia.
openings in the front grille.Using a small screwdriver
or pencil press the reset button (with minimal amount
of force) through the 1/4” opening, then restore power
to the unit. If fault continues disconnect power and
check for causes.
THERMAL CUTOUT IDENTIFICATION
All 480V Models employ a automatic limit control.
208, 240 and 277V models may employ zero-volt or
capillary manual reset limit control.
Models with capillary type manual reset limit control.
This device is located on the heater venturi (bottom of
unit as installed) with the capillary routed around the
outside of the element assembly.

OPTIONALLOUVEREDDIFFUSER
The factory installed louvered diffuser can be
adjusted to direct air flow as desired. If necessary the
louvered diffuser can be rotated 90 degrees by
removing the four mounting scews and turning the
louvered diffuser to the desired position and attaching
to the grille. Care must be taken to align the notched
corners of the diffuser frame with the reset holes in the
grille. The louvered diffuser cannot be used in
conjunction with the standard circular outlet.
