ment of the proximity switch. The kit contains a sensor
mounting bracket (A), activator (B), sensors (C), and a
cable for connecting to the Therm-O-Flow 20 control
panel. See F . 28.

With the optional light tower a yellow light indicates a
pail low condition. A flashing yellow light indicates a pail
empty condition. In a tandem system a red light indi-
cates both pails are empty. See Light Tower Kit
(253547), page 61.
When ordering this kit individually to connect to an exist-
ing Therm-O-Flow 20 unloader assembly, use the bolts,
screws and washers provided to mount to the closest
ram post to the control panel. Mount the limit switches to
the bracket as shown.
Increasing the distance between the low and empty sen-
sors (C) increases the heat up time for the tandem sec-
ondary system. Lowering the pail empty sensor forces
the heated platen lower into the pail. If this is set too low
the pump could cavitate causing a system alarm.
