Built-in Filtration System Service Procedures

 

Filtration System Problem Resolution

 

One of the most common causes of filtration problems is placing the filter paper on the bottom of the filter pan rather than over the filter screen.

 


Whenever the complaint is the pump is running, but no oil is being filtered,” check the installation of the filter paper, and ensure that the correct size is being used.  While you are checking the filter paper, verify that the O-rings on the pick-up tube of the filter pan are in good condition.  Missing or worn O-rings allow the pump to take in air and decrease its efficiency.

 

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 at the front of the fryer

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 (cold  oil  is  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 Shortening Disposal Unit

or other appropriate metal container.

 

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)

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 on the following page


10. Reconnect the unit to the electrical power supply, and verify that the pump is functioning correctly (i.e., when a filter handle is placed in the ON position, the motor should start and there should be strong suction at the intake fitting and outflow at the rear flush port.)

 

11. When proper operation has been verified, reinstall the back panels and the filter pan and lid.

 

12. Reposition the fryer under the exhaust hood and reconnect it to the electrical power supply to return the fryer to service.

 

 

 

Replacing the Filter Transformer or Filter Relay

 

Disconnect the fryer from the electrical power supply.  Remove the left controller from the fryer to expose the interior of the left component box.  The filter transformer and relay are located as shown in the illustration below.  NOTE:  The right component box is identical to the left except that the filter transformer and relay are not present.  The components are held on by threaded pin studs so that only removal of the nut is required to replace the component.


Basket Lift Service Procedures

 

 

RE Series electric fryers may be equipped with automatic basket lifts.  Basket lifts always come in pairs, although each operates independently.

A  modular  basket  lift  (illustrated  on  the  following  page)  is  a  self-contained  sub-assembly

consisting of a pair of toothed rods which support removable basket lift arms, a pair of reversible- drive gear motors, and four microswitches.  The gear motors engage the teeth of the rods, moving them up or down depending upon the motors’ direction of rotation.  The microswitches at the upper and lower limits of movement stop the motors when the basket is in the full up or full down position.


Timing  circuitry  in  the  controller  initiates  and  stops  basket  lift  operation  depending  upon  the variables programmed by the operator. When the product button is pressed, the timing circuitry activates a coil in the basket lift relay to supply power to the lower microswitch. The microswitches stop the motor at the lifts upper and lower travel limits and reverse the direction of current flow thus reversing the motor direction.

 

When the product button is pushed on the computer/controller, current flows through a coil in the basket lift relay, causing the lower circuit to be activated.   The basket lift lowers, closing the normally open upper-micro-switch.   When the downward-moving rod opens the lower normally closed microswitch, the power to the motor ceases to flow.  When the computer/controller times out, the current to the relay coil is cut, allowing the upper circuit to be activated.  The basket lift then raises and re-closes the lower microswitch.  When the basket lift rod clears the upper microswitch, the microswitch reopens, power to the circuit is cut, and the motor stops.  Pushing the product button restarts the cycle.

 

Problems with the basket lift can be grouped into three categories:

●    Binding/jamming problems

●    Motor and gear problems

●    Electronic problems

 

MOTOR AND GEAR PROBLEMS

 

With the modular basket lift, the most likely problem to be encountered in this category is erratic motion of the lift due to a worn drive gear.   Failure to keep the lift rod and bushings properly lubricated will cause unnecessary wear of the gear.  The problem is corrected by replacing the worn gear.

 

If the lift cycles correctly but fails to remain in the up position (i.e., goes up, but then slowly settles back down into the frypot), the problem is a failed motor brake. A failed motor brake cannot be repaired and requires replacement of the motor itself.

 

If power is reaching the motor but the motor fails to run, the motor is burned out and must be replaced.

 

ELECTRONIC PROBLEMS

 

Within this category are problems associated with the relays, microswitches, capacitors, resistors, interface board, wiring, and controls.   The most common problem in this category is a lift that continuously travels up and down.  This is usually caused by a microswitch that is out of adjustment. Troubleshooting the electronics of a modular basket lift is simply a process of verifying current flow through the individual components up to and including the motor.  Using a multimeter set to the 250

VAC range, check the connections on both sides of the component for the presence of the applied line  voltage.    The  schematic  below  and  the  wiring  diagram  on  page  1-16  can  identify  the components and wiring connection points.
