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.
1.8.6 Frypot
Leakage
Frypot leaks are almost always due to improperly sealed high-limit, thermostats/temperature probe
and drain fittings. When installed or replaced, each of these components must be sealed with Loctite
PST567 sealant or equivalent to prevent leakage. In very rare cases, a leak may develop along one
of the welded edges of the frypot, or where the tube is welded to the frypot. When this occurs, the
frypot must be replaced.
If the sides or ends of the frypot are coated with oil, the most likely cause is spillage over the top of
the frypot rather than leakage.
