• The operator attempted to filter oil or shortening that was not heated. Cold oil and shortening
are thicker and cause the pump motor to work harder and overheat.
If the motor tries to run but the pump does not, there is a blockage in the pump. Incorrectly sized or
installed paper will allow food particles and sediment to pass through the filter pan and into the
pump. When sediment enters the pump, the gears can bind up causing the motor to overload, again
tripping the thermal overload. Solidified shortening in the pump will also cause it to seize, with the
same result.
A pump seized by debris or hard shortening can
usually be freed by manually moving the gears
with a screwdriver or other instrument.
1. Disconnect power to the filter system.
2. Remove the input plumbing from the pump.
3. Use a screwdriver to manually turn the gears.
• Turning the pump gears backwards will
release a hard particle and allow its re-
moval.
• Turning the pump gears forward will
push softer objects and solid shortening
through the pump and allow free move-
ment of the gears.

Incorrectly sized or installed paper will also 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. The heater strip
on the suction tube is designed to prevent solidification of residual shortening left in the tube. It 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. Com-
pressed air or other pressurized gases should not be used to force out the blockage.
Possible problems with the Power Shower include clogged openings, shortening solidified in the
tubes, missing clean-out plugs, and missing or worn O-rings. Cleaning the unit and replacing miss-
ing plugs and missing or worn O-rings will correct these problems.
The electronics of the Filter Magic II are simple and straightforward. Microswitches, attached to the
drain valve handles of each vat and wired in parallel, provide the 24 VAC needed to activate the
pump relay coil when the handles are moved to the ON position. The activated coil pulls in the
pump motor switch, supplying power to the motor.
