Installation Instructions
WARNING: Wiring procedures and connections should
be in accordance with the National Electric code (NEC) and
local codes.

PERMANENT OR SUPPLEMENTARY ELECTRIC FORCED
AIR HEATING FROM THE SAME VERSATILE UNIT
These heavy-duty heaters provide spot heating for hard to
heat areas, or they can be used as the primary source of
heat for areas not reached by an existing heating system.
The fan and motor are carefully matched to insure quiet,
trouble-free operation and fan blades are precision balanced
before installation.
Heaters in all capacities (3, 5, 7-1/2, 10 or 12kw) have the
same dimensions, and use the same mounting brackets. All
components and controls, including thermostat, transformers,
relays, and switches are enclosed inside the case. Wiring
is simple and all heaters can operate from a single power
source.
HEATER LOCATION
Unit heaters should be located along outside walls to provide
perimeter air circulation. The discharge air should wipe the
walls without blowing directly on them. (Figure 1)
Small rooms• - can be heated by one or two units.
Locate the unit heater(s) to provide circular air movement
within the space.
Large rooms • - requiring multiple unit installations. Units
should be located so that the discharge air from one unit
supports the discharge from another unit and provides a
circular air movement.
Remote thermostats • - should be located on interior
walls or posts away from heat sources, cold drafts, and
away from heater discharge streams.
MOUNTING UNIT HEATER(S)
Heater should be mounted a minimum of ten (10) inches
from walls and six (6) feet above oor (8 feet for vertical air
ow) with the discharge parallel to or away from wall.
MOUNTING BRACKET • - The heater is shipped with
a mounting bracket packed separately in the carton.
Secure the bracket to threaded attachment points on
the sides of the heater with two bolts (provided). Select
desired angle of tilt (Horizontal, 15, 30, 45, 60, 75, or
Vertical), remove corresponding knockouts on sides
of the heater, then screw the remaining two bolts into
the threaded holes in the bracket so that the bolts pass
through the knockout holes. The unit is now ready for
hanging.
CEILING MOUNTING• - Fasten the heater securely to
the ceiling using the center hole in the bracket or the two
holes on either side of the center hole. The Unit mounting
bracket may be attached directly to the ceiling.
WALL MOUNTING• - The heater may also be mounted
to a wall with accessory wall bracket, Part # EUHWB.
The wall bracket attaches to the center hole of the unit
mounting bracket.

All wiring to be in accordance with local and national 2.
electric codes.
Remove two screws securing the access door (See 3.
Figure 2) and swing the door down to expose the wiring
and control compartment.

Operation
CONTROLS (Factory installed)
Fan delay• - The heater is equipped with a fan delay
control. The fan will remain on for a few moments after
the elements are de-energized.
Automatic High Limit• - Each heater is equipped with
automatic reset thermal cutouts located above the
elements. Should these safety switches operate, they
will automatically reset once the element reaches a safe
operating temperature, however the cause of the high
limit condition should be determined and corrected to
insure satisfactory operation.
Thermostat• - All heaters are equipped with a hydraulic
type thermostat which has a nominal operating range of
40F (low) to 100F (high).
OPTIONAL CONTROLS (Field installed)
Remote line voltage thermostat• - An optional remote
line voltage thermostat may be used to control the
unit. Field connections may simply be connected to the
control terminal block located in the wiring compartment
in accordance with with the wiring diagram attached to
the access door.
CAUTION: Disconnect the built-in thermostat
Remote Low voltage thermostat with relay• - An
optional low voltage thermostat/relay kit may be used
to control the unit (Catalogue #EUAR11, 120V primary;
EUAR21, 208V primary; EUAR31, 240V primary;
EUAR41, 277V primary). The relay is installed through
the hole provided in the back left corner of the blower
deck. Power connections are made to the control
terminal block located in the wiring compartment in
accordance with the wiring diagram attached to the
access door. A knockout is provided on the left side of
the heater for the 24 volt thermostat control wiring. It is
important that the plastic insulation bushing be installed
into the knockout hole before running low voltage
control wiring. The thermostat is installed and wired in
accordance with the instructions packaged with the kit.
CAUTION: Disconnect the built-in thermostat
Fan only Switch• - An optional “Fan only” switch kit
(Catalogue EUAF2) is available for eld installation in
the unit. The fan switch is mounted in the space provided
adjacent to the built-in thermostat located at the front
of the unit. Field connections are made at the control
terminal block in accordance with the unit wiring diagram.
START-UP:
Before the unit is energized, the discharge louvers 1.
should be be adjusted for desired air deection. Louvers
may be adjusted for either horizontal or vertical air
deection by rotating the louvre frame. (See gure 3)
Check to see that all controls and optional accessories 2.
are operating properly.

casing to cool before attempting to work on the heater.
Under normal conditions, the heater should be cleaned 1.
once a year. DISCONNECT ALL POWER before
cleaning or servicing the heater.
All motors are lubricated for extended life operation, and 2.
will not have to be oiled.
