4. Fill Timer Operation
The timer has ten dip switches, all switches placed in
the “on” position are added together to make up the
total time delay. This freezer leaves the factory with 64,
128 and 256 in the “on” position, this is a total of 448
seconds. The preset time should be enough to fill the
hopper up to the top level probe. Fill time may be depen-
dent on what style pump is employed. The purpose of
the timer is to disable the compressor if the mix supply
runs out. When the timer expires, the mix low light will
illuminate. If the mix low light is illuminated, the com-
pressor is locked out of the electrical circuit and will not
run. It may be necessary to change the timer settings
to more closely match the pumping capacity of your
pump.
