1-3. INTRODUCTION

Installation of the KFC Computerized Control Panel on existing
Henny Penny gas pressure fryers.

Disconnect the fryer from the electrical supply source
before beginning panel conversion.

Failure to disconnect the fryer from the supply source
could result in electrical shock.

The fryer internal wiring is numbered to correspond to the
numbers on the wiring diagram, Figure 1.

1-5. NINE-PIN CONNECTOR

WIRING

A. Remove the above wires from their existing position. These

wires will be connected to the nine-pin connector provided.

B. Locate wires number 12, 8, and 11 at the fan motor. Remove

the connector securing these wires. Wire number 11 can be
discarded at this time. Wire number 12 will be connected to the
nine-pin connector as noted on the wiring diagram. Wire
number 8 from the fan motor will be joined with wire number 15
before it is connected to the nine-pin connector. Join these two
wires using the twist-on wire connector provided.

C. Note the position of the wires on the nine-pin connector.

Reference wiring diagram Figure 2. The wires on the connector
will have corresponding numbers to those within the control
panel.

D. Using the twist-on wire connectors provided, splice the

corresponding wires together.

E. Wiring of the nine-pin connector is completed.

“Do not install the control panel at this time.”

1-6. TEMPERATURE PROBE

INSTALLATION

A. Drain the shortening from the cook pot to a level below

the position of the thermostat pot fitting.

B. Remove the thermostat capillary tube from the cook pot

as per section 5-11 of standard Henny Penny Service Manual.

C. Install the reducer fitting, Henny Penny part number

FP01-024 into the pot wall fitting. Use pipe sealant to seal
the pipe threads.

D. Install the compression fitting, part number 30094, Figure

3 into the reducer. Use pipe sealant to seal the pipe threads.

E. Install the new probe by inserting the probe into the compression

fitting until the probe extends one-half (1/2) inch into the cook pot.
Tighten the nut on the compression fitting a half a turn past the
point where the fitting first becomes tight onto the probe.

Excess force will damage the probe.

F. Installation of the temperature probe is complete.

1-7. SLOT COVER

When installing the computerized panel retrofit kit, it is necessary
to cover the existing slot in the heat shroud. This slot allows the
capillary tube of the old control panel to extend through the heat
shroud when mounting the old control.

A. Open door and push slot cover through shroud from bottom

of the shroud.

B. Bend the 4 tabs of slot cover over the top of the heat shroud.

1-8. CONTROL PANEL

INSTALLATION

A. The new computerized panel is positioned and installed exactly

like the existing electromechanical control panel.

B. Place the computerized control panel on top of fryer frame

and door.

C. Mate the nine-pin connectors together. Refer to KFC gas

wiring diagram.

D. Connect the temperature probe to the control panel board.

E. Install the control panel and two screws. When installed

properly there will be approximately a 7/16 inch of a gap
between the bottom of the control panel and fryer rail.

F. This completes the electrical and mechanical installation of

the computerized control panel.
