7. Complete Control Panel Henny Penny

This high temperature control is a manual reset control which
sensesthe temperature of the shortening. If the shortening
temperature exceeds 420°F (215OC),this control switch will
open and shut off the heat to the cookpot. When the
temperature of the shortening drops to a safe operation limit,
the control must be manually reset. The reset button is located
above the filter knob in the front of the cooker. This will allow
heat to be supplied to the cookpot.
Before replacing a high temperature limit control, check to
see that its circuit is closed.
The shortening temperature must be below 380°F
(193°C) to accurately perform this check.
1. Remove electrical power supplied to the fryer.
Remove electrical power supplied to the fryer by
unplugging the unit, or by turning off the wall circuit

Primary
Heat
The electric fryer requires two switching contactors: aprimary
contactor and a heat contactor. The primary contactor
energizes (contacts close) any time the Power/Pump Switch
is in the “Power” position and the temperature of the pot is
below 420°F (215OC). The hi limit will cut the power at the
primary contactor if temperatures in the cookpot exceed420°F
(215O6). The primary contactor supplies power to one side of
the heat contactors.
The heat contactor is controlled by the computer controller.
en the controller calls for heat, the heat contactor applies
power to one side of the heating elements. When the heat
contactor and the primary contactor are energized (contacts
closed), the electric heating elements heat the shortening.

Each electric fryer uses two heating elements.
Heating elements are available for 208 or 220/240,380
and 415 voltage. Check the data plate on the right side
panel of unit to determine the correct voltage.
If the shortening’s temperature recovery is very slow, or at
a slower rate than required, this may indicate defective heating
element(s). A multimeter will quickly indicate if the elements
are shorted or open.

All fryers are equipped with a drain valve micro-switch that
prevents heat from coming on when the drain valve is open.
With the drain valve open, the switch prevents power from
being applied to the coil of the primary and heat contactors,
and the solenoid coil.
Remove electrical power supplied to the fryer by
unplugging the unit, or turning off the wall circuit
breaker or electrical shock could result.

5-13. PRESSURE REGULATION The Henny Penny Fryer uses pressure as one of the
components of the cooking process. Once the lid is
sealed to the cookpot, and the solenoid valve closes, a
deadweight valve maintains the correct pressure in the
cookpot.
The lid has minimal and limited maintenance and
repair procedures, which are addressed in the
following sections.

5-14. PREVENTIVE
MAINTENANCE
The following is a routine maintenance schedule for the Lid:
Every 90 days
•Clean and reverse lid gasket
Yearly Cleaning and Inspection
•Remove and clean Safety Relief Valve
•Check Lid Gasket for splitting and tears - replace if necessary
•Check Pressure Pads for wear - rotate if necessary
•Check Cam Slide Guides - replace if worn or broken
•Check Lid Rollers - replace if cracked or damaged.
5-15. REVERSING LID The gray rubber gasket surrounding the inside of the lid is designed
GASKET to be reversed. HENNY PENNY RECOMMENDS THIS BE
DONE EVERY 90 DAYS.
Because heat expansion and the pressure used for the cooking
process, the gasket is constantly under extreme stress. Reversing
the lid gasket every 90 days helps to assure the fryer won’t lose
pressure through leakage.
1. Open the lid completely, tilt lid back, and lock lid in place with
the “kickstand”.
2. Using a thin blade screwdriver pry out the gasket at the corners.
Remove the gasket.

Check the gasket for any tears or nicks. If the gasket
is damaged it needs to be replaced.
Be careful that the lid doesn’t fall down while it is in
the upright position, or serious injury could result.
3. Clean the gasket and gasket seat with hot water.
4. Rotate the gasket with the opposite side facing out.
Begin the installation by installing the four corners of
the lid gasket, and smoothing the gasket into placefrom
the corners. ,
The Lid Counterweight in the back of the fryer balances the
weight of the lid system to allow easier opening and closing
of the lid. The weight has two cablesattached to it, and weighs
about 150 lbs. (67.5 ). One cable is centered on the weight
and is the cable being used. The other cable is a safety cable
and is off center. In case the main cable becomes loose or
broken, the safety cablecatchesthe weight and puts the weight
into a bind, not allowing the lid to be opened or closed.
1. Using a 3/8” socket, remove the back shroud of the fryer.
2. With one person holding the weight level, another person
locks the lid down.
3. Unthread the broken cable from the weight and the
bracket attached to the fryer, and remove broken cable.
4. Thread a 506” nut on each end of the new cable.
5. Screw the new cableinto the weight, using a wrench, until
it is tight.
