1.9.5 Filtration Problems (cont.)
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 installed in the pan during filtering.
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.
Compressed 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
missing 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
oil-return 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.
The suction tube heater and flexible hose heater are wired directly into the 24VAC source. They
remain energized as long as the unit is plugged in (see diagram below).
