1.11 Basket Lift Service Procedures
H14/H17/H22 Series fryers may optionally be equipped with automatic basket lifts to ensure
uniform cooking times. Basket lifts will always come in pairs, although each operates
independently.
All electric fryers are equipped with “modular” basket lifts.
A modular basket lift (illustrated below) consists of a toothed rod to which the basket lift arm is
attached, a reversible-drive gear motor, and a pair of roller-activated microswitches. The gear motor
engages the teeth in the rod, moving it up or down, depending upon the direction of rotation of the
motor. Microswitches at the upper and lower limits of movement stop the motor 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.
