Info

If the pump motor overheats, the thermal overload will trip and the motor will not start until it is reset. If the pump motor does not start, press the red reset switch (button) located on the rear of the motor. If the pump starts after resetting the thermal overload switch, then something is causing the motor to overheat. A major cause of overheating is when several frypots are filtered sequentially, overheating the pump and motor. Allow the pump motor to cool at least 30 minutes before resuming operation. Pump overheating can be caused by: • Solidified shortening in the pan or filter lines, or • Attempting to filter unheated oil or shortening (cold oil and shortening are more viscous, overloading the pump motor and causing it to overheat). If the motor runs but the pump does not return oil, there is a blockage in the pump. Incorrectly sized or installed paper/pads will allow food particles and sediment to pass through the filter pan and into the pump. When sediment enters the pump, the gears bind, causing the motor to overload, again tripping the thermal overload. Shortening that has solidified 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. Disconnect power to the filter system, remove the input plumbing from the pump, and use a screwdriver to manually turn the gears. ● Turning the pump gears in reverse will release a hard particle. ● Turning the pump gears forward will push softer objects and solid shortening through the pump and allow free movement of the gears. Incorrectly sized or installed paper/pads will also allow food particles and sediment to pass through and clog the suction tube on the bottom of the filter pan. 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. 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. 1.9.2 Replacing the Filter Motor, Filter Pump, and Related Components 1. Remove the filter pan and lid from the unit. Drain the frypots into a McDonald’s Shortening Disposal Unit (MSDU) or other appropriate metal container. 1-10 Sediment Particle Sediment Particle Oil Flow Up for reverse Down for forward
DANGER DO NOT drain more than one full frypot or two split frypots into the MSDU at one time. 2. Disconnect the fryer from the electrical power supply and reposition it to gain access to both the front and rear. 3. Disconnect the two flexlines running to the oil-return manifold at the rear of the fryer as well as the pump suction flexline at the end of the filter pan connection (see photo below). Disconnect flexlines indicated by the arrows. 4. Loosen the nut and bolt that secures the bridge to the oil-return manifold. 5. Remove the cover plate from the front of the motor and disconnect the motor wires. 6. Unplug the pump motor assembly 6-pin connector C-2 and, using a pin pusher, disconnect the vent vacuum-breaker solenoid (pins 2 and 5) that is attached to the oil return manifold. 7. Remove the two nuts and bolts that secure the front of the bridge to the cross brace and carefully slide the bridge rearward off the cross brace until its front end can be lowered to the floor. Undo the single nut holding it in place in back. Be careful not to let the rear of the bridge slip off the manifold at this point. 8. Get a good grip on the bridge, carefully pull it forward off the oil-return manifold, and lower the entire assembly to the floor. Once on the floor, pull the assembly out the front of the fryer. 9. When required service has been completed, reverse steps 6-12 to reinstall the bridge. NOTE: The black motor wires go on the top terminal, the white on the bottom. The pump solenoid valve wires go in positions 1 and 4 of the 6-pin connector C-2; the vent vacuum-breaker solenoid valve wires go in positions 2 and 5; the red/black heater tape wires go into position 3 and the violet/white wires go into position 6 (see illustration below). 1-11
