best sense the discharged air temperature around
the door opening. Connect proper voltage to the
product per local and NEC codes. (FIG. 2)
Thermal overload protection is built into the heater
coil assembly/assemblies. In the event of an
overload condition, electrical power will be
disconnected from the heater coil. Upon diagnosing
the problem, electrical power can be re-instated to
the heater coil(s) by manually resetting the thermal
overload lever(s) or buttons(s) located in the unit or
panel.
To operate multiple units mounted side by side,
utilizing a single door switch and single
thermostat, a master/slave configuration is
required. (FIG. 2)
