CHAPTER 1: SERVICE PROCEDURES
1.8.5 Improper Filtration Function
(cont.)
Incorrectly sized or installed paper will allow food particles and sediment to pass through and
clog the suction tube on the bottom of the filter carriage. Particles large enough to block the
suction tube may indicate that the crumb tray is not being used.
Pan blockage can also occur if shortening is left in the pan and allowed to solidify. Heater
strips (if equipped) on the oil return plumbing are designed to prevent solidification of
shortening left in the plumbing. Heater strips will not melt or prevent solidification of
shortening in the pan.
Remove blockage by forcing it out with an auger or drain snake. DO NOT use compressed air
or other pressurized gases to force out the blockage.
The SUFF/UFF filtration systems use microswitches attached to handles for each vat. They are
wired in parallel and 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 the pump motor
switch in, supplying power to the pump motor.
Filter systems equipped with oil-return heater tape are wired into the 120 VAC source and
remain energized as long as the unit is plugged in and power remains constant. Heater tape
should receive constant power all day and all night; it should not be connected to a power
supply that is turned off at night.
