1.8.4 Filtration Problems
The majority of filtration problems arise from operator error. One of the most common errors is
placing the filter paper on the bottom of the filter pan rather than over the filter screen.
Whenever the complaint is "the pump is running, but no oil is being filtered", check the installation
and size of the filter paper. Verify that the O-ring on the slip-connection is in good condition. A
missing or worn O-ring allows the pump to suck air, decreasing its efficiency.
If the pump motor overheats, its 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 located on the rear of the motor.
Also, reset the filter circuit breaker located under the fryer control panel. If the pump then starts,
something caused the motor to overheat. Maybe several frypots were filtered one after the other and
the pump got hot. Letting the motor cool down for at least a half-hour is all that is required in this
case. More often, the pump overheated for one of the following reasons:
• If solid shortening is used: Shortening solidified in the pan or filter lines.
• The operator attempted to filter unheated oil. Cold oil is thicker and causes the pump motor to
work harder and overheat.
If the motor runs but the pump does not, there is a blockage in the pump. Incorrectly sized or
installed paper allows food particles and sediment to pass through the filter pan and into the pump.
When sediment enters the pump, the gears bind up causing the motor to overheat, tripping the
thermal overload. Solidified shortening in the pump will produce the same result.
A pump seized by debris or hard shortening must be disassembled, cleaned and reassembled.
1. Disconnect power to the filter system.
2. Remove the front cover of the pump to access the gears inside (see illustration- 8-GPM pump
shown), if the pump is accessible while still inside the cabinet. If the front cover is not
accessible, the pump must be removed from the pump motor (remove input/output plumbing
from the pump prior to removing pump). Remove three setscrews to disengage the pump from
the motor.
Remove bolts to remove
pump cover.
Remove debris or hardened
shortening to free gears.
