INSTALLATION

DANGER

Appliances must not be installed where they may be exposed
to a potentially explosive or flammable atmosphere.

CAUTION

1. Be sure no obstructions block air intake or discharge of
the appliance.

2. Do not install appliance in outdoor, wet, or moist

locations.

In locating units, consider general space-heating requirements
of the area. Unit heaters should be located so they discharge
air nearly parallel to exposed walls. Arrange units so they do
not blow directly at occupants. Interference of air streams by
columns, beams, partitions, or other obstructions should be
avoided as much as possible.

In multiple unit installations, arrange units so that each supports
the air stream of the next unit, thus creating circulatory air
movement in the area. See Figure 3.1. A large portion of the
heated air should be directed toward the side of the building
exposed to prevailing winds.

Height at which unit heaters are installed is critical. Maximum
mounting heights for all units are listed in Table 7.1. The
maximum mounting height for any unit is that height above
which the unit will not deliver heated air to the floor. The
maximum mounting heights must not be exceeded in order
to assure maximum comfort. It is critical that the unit has
adequate clearance from combustible materials as listed in
Table 3.1.

UNIT MOUNTING

For best performance do not install the unit heater above the
maximum suggested mounting height shown in Table 7.1. Do
not install the unit below 6ft in the USA, or 8ft in Canada shown
in Table 7.1. The bottom of the unit must be unobstructed, and
may not be used on a shelf or platform. The unit is provided
with a mounting rail, hanging bracket, and hardware to install in
a ceiling-mounted application, shown in Figure 3.2. Be sure the
means of suspension is adequate to support the weight of the
unit (see table 7.1 for unit weights). For proper operation, the unit
must be installed in a level horizontal position.

Standard ceiling mounting (Figure 3.2):

Secure the mounting rail to the ceiling joists or truss, using
¼” lag screws with minimum ½”OD washers furnished by the
installer. Insure clearance for unit installation and removal.
The mounting rail is slotted to accommodate joists on 16” or 24”
centerlines, and can be installed across joists or on the same joist
depending on desired unit position and access.

One tapped hole (1/2”-13) is provided in the top of the casing for
unit heater suspension. A hanging bracket is supplied with the
unit, and should be installed with the provided 1/2" -13 x 1-1/4"
cap screw and washer. This bolt should be secured to the unit
to a minimum of 24 ft-lbs of torque . This bracket can be installed
at an angle if required for insertion to the mounting rail. Once
installed, slide the hanging bracket into the mounting rail, and
secure from the front with the provided #10-16 screw to prevent
movement of the heater in the rail, see Figure 3.2.

OPERATION

WARNING

The heater must be properly installed before use.

IMPOR T ANT

Start-up and adjustment procedures must be performed by a
qualified service agency.

Prior to Operation

Although this unit has been inspected and tested at the factory,
the following procedures should be performed to assure proper
on-site operation:

1. Check all electrical connections to be sure they are secure,
and in accordance with the wiring diagram.

2. Check firmness of unit suspension. Tighten all fasteners, if

necessary.

Safety Devices

The overheat controls, mounted on the bottom of the control
section (See Figure 6.1), will interrupt power to the unit
contactor in the event of overheating. The limit nearest the fan
scroll is a single-pole, single-throw switch, with an automatic
reset. The limit nearest the control panel opening is a single­pole, single-throw switch, with a manual reset. If either of
these limits is tripped, the red overheat alarm indicator on the
front of the unit will illuminate (See Figure 6.2). During this
state, power to the elements will be disrupted, but the controls
will permit the motor to continue operation and cool the
heater. The overheat controls should operate only when

something is wrong with the unit or space temperature.
When this control operates, correct the difficulty
immediately or serious and permanent damage may
result. If the Overheat Alarm indicator light is illuminated, it is

recommended that the unit be disconnected from power at the
breaker until the unit can be inspected and the issue resolved.
Do not continue to use heater if it repeatedly overheats to cycle
the safety thermal limit.

The motor for the blower wheel has internal thermal overload
protection. If for any reason the motor overheats, the thermal
protector will shut it off. The motor will restart automatically
when it has cooled. In the event of a complete motor failure,
the manual limit will trip and prevent the elements from heating/
cycling. Following motor servicing/replacement, the manual
reset button must be pressed to reset the switch prior to the
elements functioning again.

Initial Start-Up

1. Set thermostat above room temperature.

2. Turn on power to the unit.

3. Run the unit through several cycles by raising and lowering
the thermostat setting to assure proper sequence of
operation.

Operating Sequence

The operation of this electric unit heater is governed by
a microprocessor control board which is controlled by a
thermostat. The board completes the electric circuit to the
heating elements when the thermostat “calls” for heat. The
green ‘Heating Mode’ indictor light on the front of the unit will
illuminate when this occurs. The fan motor is also activated
shortly after the thermostat “calls” for heat. When the thermostat
is satisfied, the control board opens the circuit to the heating
elements. There is a cooldown period where the fan will
continue to operate after the elements are de-energized to
dissipate the remaining heat from the elements before fully
shutting off.
