INSTALLATION
Installing the Base
Locate a visible 4” x 5” space outside the food container to mount the
ThermoAlert base unit. Make sure that the area does not limit access
to the maintenance panels. Mount the base unit with 1/8” bolts with
plain and spring washers using the diagram below as a guide.
Installing Sensors
Drill a ½” hole through the container wall next to the based unit. Push
sensors carefully through the hole one at a time. Fasten one of the
sensors near the top and the other one near the bottom of the
container. Sensors are identical and are both calibrated for the same
temperature range. Fill the hole with a water resistance silicon paste.
Wiring the Unit
Locate the main power switch of refrigeration unit. Locate positive
and negative poles of the switch. Make sure that you have power in
these poles even if the safety switch turns off the main power. You
may need to replace the main switch with a DPDT (Double-Pole,
Double-Throw) switch. Connect the red wire of ThermoAlarm’s power
cable to the positive and the black wire to the negative pole of the
