CHAPTER 1: SERVICE PROCEDURES
1-24
A pump seized by debris or hard shortening must be disassembled, cleaned and reassembled as
follows:
1. Disconnect power to the filter system.
2. Remove the front cover of the pump to access the gears inside, 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
setscrews to disengage the pump from the motor.
Remove these bolts (6) to
remove pump cover.
Remove debris or hardened
shortening to free gears.
3. Prior to reassembly, the inside housing must be clean and free of any sediment or debris. Failure
to completely clean the inside housing and ring gear will cause gear binding after reassembly.
4. During reassembly, partially install the housing bolts in a star pattern, leaving a ⅛-inch (3.18
mm) gap between the cover and housing flanges. Ensure there is no shortening or oil in the filter
pan, and that the filter pan is disconnected. With the motor running slowly draw the cover in,
evenly tightening the housing bolts. When the cover is snug on the housing tighten all bolts to
15 inch-lbs (1.7 Nm) ensuring that the pump is working correctly. Turn the motor off.
An incorrectly assembled or damaged filter leaf will allow food particles and sediment to pass
through and clog the pump. Particles large enough to clog the pump may indicate that the crumb
tray is not being used, and that the filter leaf is not properly assembled.
The electronics of the SUFF/UFF filtration systems are simple and straightforward. Microswitches,
attached to handles for each vat and wired in parallel, provide the 24 VAC required to activate the
pump relay coil when the handles are moved to the ON position. The activated pump relay coil pulls
in the pump motor switch, supplying power to the pump motor.
Filter systems equipped with oil-return heaters are wired into the 120 VAC source, which remain
energized as long as the unit is plugged in.
