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. Never
attempt to use compressed air or other pressurized gases 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 and FootPrint III 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.
