Filtration Problem Resolution
One of the most common errors is placing the filter paper on the bottom of the filter pan rather than
over the filter screen.
CAUTION
ENSURE THAT FILTER SCREEN IS IN PLACE PRIOR TO FILTER PAPER
PLACEMENT AND FILTER PUMP OPERATION. IMPROPER SCREEN PLACEMENT IS
THE MAJOR CAUSE OF FILTER SYSTEM MALFUNCTION
Whenever the complaint is “the pump is running, but no oil is being filtered,” check the installation
of the filter paper, and ensure that the correct size is being used. While you are checking the filter
paper, verify that the O-ring on the bottom of the filter pan is present and in good condition. A
missing or worn o-ring allows the pump to take in air and decreases its efficiency.
If the pump motor overheats, the thermal
overload will trip and the motor will not start
until it is reset. If the pump motor does not start,
press the red reset switch (button) located on the
rear of the motor.
If the pump starts after resetting the thermal
overload switch, then something is causing the
motor to overheat. A major cause of overheating
is when several frypots are filtered sequentially at
one time, thus overheating the pump and motor.
Allow the pump motor to cool at least 30 minutes
before resuming operation.
Pump overheating can be caused by:
•
Solidified shortening in the pan or filter
lines,
Or
•
Attempting to filter unheated oil or
shortening.
Cold oil and shortening are more viscous,
causing the pump motor to loadup and overheat.
