PRINCIPLES OF OPERATION
When the thermostat calls for heat, the elements
are immediately energized, a fan delay brings on
the fan after the elements are heated allowing
warm air to circulate. When the thermostat is
satised, the elements are de-energized and the
fan purges the heater of residual heat.
The heater wattage may be eld adjusted only on
model 961-U5000V-T. Select the desired wattage
from Fig.1 and move color coded jumpers as
indicated.

MOUNTING THE HEATER
Select the mounting location. Be sure to observe
the minimum mounting clearances as shown in
Figure 2.
The heater can be mounted either from the
ceiling or wall depending on the application.
The mounting bracket is supplied with 3/8” holes,
10 inches on center for threaded rod mounting or
direct mounting to the structure.
The heater cabinet also has 3/8” weld nuts 10” on
center to allow threaded rod mounting without the
bracket.
1. Install the mounting bracket in the desired
location with threaded rod or hardware
that is appropriate for the mounting surface.
If using threaded rod, two nuts, one on the top
and one on the bottom of the bracket along
with a split washer is suggested.
2. Secure the heater to mounting bracket, using
the 1/4-20 x 3/4” machine screws and
lockwashers provided.
3. Position the heater, aligning the bracket holes
with the cabinet holes and secure bracket to
the cabinet with the 1/4-20 x 1/2” machine
screws and nuts that are provided. With the
mounting bracket in the vertical position the
1/4” nuts are not necessary, weld nuts are
supplied in the cabinet.
