INSTALLATION Locating Unit Heaters In locating heaters, consider general space-heating requirements of the area. Unit heaters should be located so that exposed walls are blanketed with warm air. In multiple unit installations, arrange units so that the air discharge pattern of one unit overlaps the next unit thus encompassing the area (See Fig. 3.1 & 3.2). Interference of air streams by columns, beams, partitions or other obstructions should be avoided as much as possible.

INSTALLATION Figure 4.1 - Vertical Model VE with Cone Jet Accessory Installed Model VE Unit Suspension There are four tapped holes (1/2''-13) in the top of the unit for unit suspension. Unit suspension can be made with threaded rods, pipes, or ceiling hanger brackets furnished by others. See Figure 4.3. Figure 4.3 - Unit Suspension Method of Vertical Delivery Units ANGLE BRACKET FASTENING Figure 4.

Figure 5.1 - Rear view of Model PTE For easier installation of PTE model electric unit heaters, where ceiling suspension is not feasible, a wall-mounting bracket kit is available. The bracket saves installation time, has a built-in wall clearance, and provides an inexpensive and convenient wall-mounting method. The one-point suspension, shown above, permits swiveling the unit 180 degrees horizontally for most effective air direction.

OPERATION Figure 9.1 - Cutaway of Electric Unit Heater 3 2 1 7 8 Operating Sequence The operation of Modine electric unit heaters is governed by an electrical contactor which is controlled by a thermostat. The contactor completes the electric circuit to the heating elements when the thermostat “calls” for heat. The fan motor is also activated when the thermostat “calls” for heat. When the thermostat is satisfied, the fan motor stops and the contactor opens the circuit to the heating elements.
