1.10 Built-in Filter System Service Procedures (cont.)
If the pump motor overheats, a circuit breaker will trip and the motor will not start until the breaker
is reset. If the pump motor does not start, press the white reset button located under the component
box, inside the cabinet.
If the pump starts after resetting the breaker, then something is causing the motor to overheat. A
major cause of overheating is when several frypots are filtered sequentially, thus overheating the
pump and motor. Allow the pump motor to cool at least 30 minutes before resuming operation, and
allow time for the motor to cool between sequential frypot filtering.
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 load up and overheat. Always
filter with the oil or shortening at operating temperature [~350°F (177°C)].
If the motor runs but the pump does not, there is a blockage in the pump. Incorrectly sized or
installed paper/pads will allow food particles and sediment to pass through the filter pan and into the
pump. When sediment enters the pump, the gears bind, causing the motor to overload, again
tripping the thermal overload. Shortening that has solidified in the pump will also cause it to seize,
with the same result.
A pump seized by debris or hard shortening must be disassembled, cleaned, and then reassembled
before continuing use. Use the following procedure:
1. Disconnect power to the filter system.
2. Remove the front cover of the pump to access the gears inside (see illustration below- 8-GPM
pump shown), if the pump is accessible while still inside the cabinet.
