Replacing The Filter Transformer Or Filter Relay; Basket Lift Service Procedures - Frymaster FootPrint PRO OCF30 Series Service & Parts Manual

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, if
necessary to return the fryer to service.
1.9.3 Replacing the 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 transformer and relay on the left are located as
shown in the illustration below. NOTE: The right component box is identical to the left except that
the transformer and relay on the left side are not present. Once replaced, reconnect the power.
When replacing a filter relay in the left component box, ensure the 24VAC relay (8070670) is used on
208-240V units and 8070012 is used on 120V units. This relay is the same relay used in the RE
fryers.

1.10 Basket Lift Service Procedures

™
OCF30 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 lift's 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 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 controller times out, the current to the relay coil is
