Verifying Solenoid Operation

Proper operation of the 24 VAC manifold and pump solenoids can be verified by removing the pump motor lead from terminal 4 of the pump motor relay in the filter wiring box and then activating the oil return lever. Proper solenoid operation will be evidenced by an audible “click” or vibration of both the pump solenoid and the manifold solenoid.

1.7.6 Leakage

Leakage of the frypot will usually be due to improperly sealed high-limit thermostats, temperature probes, and drain fittings. When installed or replaced, each of these components must be sealed with Loctite® PST56765 sealant or equivalent to prevent leakage. In very rare cases, a leak may develop along one of the welded edges of the frypot. When this occurs, the frypot must be replaced.

If the sides and/or ends of the frypot are coated with oil/shortening, the most likely cause is spillage over the top of the frypot rather than leakage.

The clamps on the rubber boots that hold the drain tube sections together may loosen over time as the tubes expand and contract with heating and cooling during use. In addition, the boot may be damaged. If the section of drain tube connected to the drain valve is removed for any reason, ensure that its rubber and clamps are in good condition and properly fitted around the drain tube when it is reinstalled. Also, check to insure that the drain tube runs downward from the drain along its whole length and has no low points where oil or shortening may accumulate.

1.7.7 Basket Lift Malfunctions

Pro H50/55 Series fryers may be optionally equipped with automatic basket lifts to ensure uniform cooking times. Basket lifts will always come in pairs, although each operates independently of the other. A modular basket lift 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. A gear on the motor shaft engages teeth in the rod. Depending upon the direction of motor rotation, the gear drives the rod up or down.

Timing circuitry in the controller initiates and stops operation of the basket lift depending upon the variables programmed by the operator. When a product button is pressed, the timing circuitry activates a coil to supply power to the motor, which lowers the basket into the frypot.

When the rod contacts and closes the lower microswitch, power to the motor is cut and the direction of current flow is reversed; this reverses the direction of motor rotation. When the programmed cooking time has elapsed, power is again supplied to the motor. The motor raises the basket from
