Leaking; Modular Basket Lift Malfunctions - Frymaster 47 Series Service & Parts Manual

1.9.6 Leaking

Frypot leaking will almost always be due to improperly sealed high-limit thermostats, operating
thermostats, temperature probes, and drain fittings. When installed or replaced, each of these
components must be sealed with Loctite™ PST567 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, which hold the drain tube sections together, may loosen over time as the tubes expand
and contract with heating and cooling during use. If the section of drain tube connected to the drain
valve is removed for whatever reason, make sure that its grommet is in good condition and properly
fitted around the nipple of the drain when it is reinstalled. Also, ensure the drain tube runs
downward from the drain along its whole length and has no low points where oil or shortening may
accumulate.

1.9.7 Modular Basket Lift Malfunctions

47 Series fryers may optionally be equipped with automatic basket lifts to ensure uniform cooking
times. The lifts may be configured for manual control or for control via a Basket Lift Timer or
Computer Magic III computer. Basket lifts come in pairs, although each operates independently.
A lift consists of a notched rod to which the
basket lift arm is attached, a reversible-drive gear
motor, and a pair
microswitches. The gear motor engages the
notches 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. In
units configured for manual (push-button)
controls, a mechanical timer controls voltage to
the system. A rotary knob is turned to set the
cook time, and pressing the button in the middle
of the knob activates the motor by applying
power through the lower microswitch.
motor drives the basket lift down. As the rod
moves downward,
microswitch, preparing the motor to run in the
opposite direction when the cooking time has
expired. When the rod contacts the lower
microswitch, power to the motor is interrupted
and the motor stops.
