Heater Safety
An integrated thermostat is mounted to the backside of the aluminum reflector. The thermostat
is wired to the pinned connector with corresponding wiring residing in the removable electrical
cable. When wired into an appropriately designed power source, the normally closed
thermostat will open upon reaching an overheat condition preventing electrical power from
reaching the heater. The thermostat will close once the heater cools down to a safe operating
temperature.
Optional Quartz Window
A quartz window can be ordered along with each size of the Model 5209. When installed in the
heater, the quartz window protects the aluminum reflector and lamps from contaminants
released in the heating process resulting in maximum efficiency of the heater.
Optional Electrical Junction Box
An optional electrical junction box can be ordered with the Model 5209. The junction box
accommodates all of the wiring present within the removable electrical cable and is designed
to accept either a 240- or 480-volt supply source.
Optional Power Control System
The Model 5209 can be ordered with the ‘PC’ option. This configuration consists of the heater,
removable electrical cable wired to a junction box and a Research Inc. Model 915 (single-
phase) or Model 935 (three-phase) SCR-based power control system, also wired to the
junction box. This power control system is designed to match the electrical supply needs of the
heater. Please see the Model 915 or Model 935 ControlIR
