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.

Figure 3.1 – Typical Unit Locations

Table 3.1 – Clearance to Combustibles

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.

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 single-pole, 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.
