SHIPPING, RECEIVING AND INSPECTION
All cardboard cartons are shipped attached to heater, with power cord installed. Inspect controls for
damage, noting any found on freight bill.
INSTALLATION
WARNING! Before installing the control, disconnect and lock out all power to heater!
Handle the control carefully. Take care not to damage the sensing element, located at bottom of control
mount.
Note: Before choosing where to mount the control to the bin, be sure the electric cord of the control will
reach the heater control panel. The preinstall cord is approximately 11’-6” in length.
Mount the control, preinstalled on mounting plate, on the bin sidewall between the perforated floor and
the concrete foundation, three feet to the side of the transition. Only the sensing bulb needs to be located
between the two. Drill one 3/8” hole on the highest point of corrugation in this area. Clean the newly
drilled hole, removing any sharp edge from drilling that may cut wires connecting the sensing bulb from
the thermostat. Using self-drilling screws, mount high-low thermostat mounting plate vertically. (See Fig.
