1.8.4 Filtration
Problems
(cont.)
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.
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.
Blockage removal can be accomplished by forcing the item out with an auger or drain snake.
Compressed air or other pressurized gases should not be used to force out the blockage.
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.
1.8.5 Leaking
Leakage of the frypot usually will be due to improperly sealed high-limits, thermostats, or 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. When this occurs, the frypot must be replaced.
If the sides and/or ends of the frypot are coated with oil, the most likely cause is spillage over the top
of the frypot rather than leakage.
