3480/RCH SERIES INSTALLATION
INSTRUCTIONS
GENERAL INFORMATION
MOUNT HORIZONTAL POSITION ONLY.
DO NOT INSTALL ANY CLOSER THAN 12” TO NEAREST WALL
MAXIMUM MOUNTING HEIGHT 12 FEET.
CHECK TO SEE THAT SERVICE VOLTAGE IS THE SAME AS HEATER VOLTAGE.
ALL WIRING MUST CONFORM TO THE NATIONAL ELECTRIC CODE AND EXISTING LOCAL CODE REQUIREMENTS.
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 using either threaded rod, or wire in an approved
method that is su󰀩cient 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 nished
ceilings, the can should be installed so the anges (of
the can) are even with the interior nish or ceiling line.
3. For plaster or other similar nish 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 align with the manual
reset limit control located on the bottom of the venturi
of the heater assembly, also make alignments 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.
WARNING: To avoid the risk of re, shock or personal injury; make sure that the power source is disconnected before
attempting to install, service, clean or disassemble 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.
IMPORTANT: OWNER SHOULD RETAIN THESE INSTRUCTIONS FOR FUTURE REFERENCE
NOTE: If plaster frame is required for installation

THERMAL CUTOUT IDENTIFICATION
All 480V Models employ a automatic limit control. 208,
240 and 277V models have a 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.
THERMAL CUTOUT OPERATION
(WITH CAPILLARY MANUAL RESET)
To reset thermal cutout, rst 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 (480 volt models)
If for any reason temperatures increase beyond normal
limits, safety thermal limit will open de-energizing
heating 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.
OPERATION
1.Turn on the power supply to heater.
2.Rotate thermostat knob fully clockwise.
3.Allow the room to reach desired temperature, then rotate thermostat knob counter clockwise until the heater de-energizes.
MAINTENANCE AND CLEANING
DISCONNECT POWER BEFORE ATTEMPTING ANY SERVICE
The heater should be cleaned at least annually to prevent excess build-up of dirt and lint accumulated under normal
operating conditions. In an unusually dirty environment the cleaning should be done more often. Using a vacuum cleaner
with soft brush attachment, clean the the intake and discharge openings of any accumulated dirt or lint. The fan blade and
elements may be cleaned after removing the front cover. The face plate can be cleaned with damp cloth and mild detergent.
The factory installed louvered di󰀨user can be adjusted to
direct air ow as desired. If necessary the louvered di󰀨user
can be rotated 90 degrees by removing the four mounting
screws and turning the louvered di󰀨user to the desired
position and attaching to the grille. Care must be taken to
align the notched corners of the di󰀨user frame with the reset
holes in the grille. The louvered di󰀨user cannot be used in
conjunction with the standard circular outlet.
