SECTION 1. INSTALLATION

1-1. INTRODUCTION

This section provides instructions for the removal of the

existing controls, and the installation of the new Henny
Penny Electronic Control Retrofit.

Installation of the kit should be preformed only by a

qualified service technician.

Do not puncture the unit with any objects such as
drills or screws as component damage or electrical
shock could result.

CONTROLS

shock

To avoid electrical shock or property damage, move

the power switch to “OFF” and disconnect main
circuit breaker, or unplug cord at wall receptacle.

1. Drain shortening from frypot.

2. Remove the Phillip’s head screws from the control

Figure 1-1 panel. Figure 1-1.

3. Cut wire ties and mark the wires to the pump(connected
to the power switch) and unplug them. Figure 1-2.
Hint: A 500/600/561 Manual may help in referring to the
original wiring diagram.

the elements and pull from frypot. Figure 1-4.

6. Disconnect and remove the remaining control wires and
connectors.
a. Disconnect remaining power switch wires.

Figure 1-4 b. Disconnect indicator light, drain switch and high

limit wires.
c. Disconnect 15 amp fuse holder wires from Primary
Contactor.

7. Pull “old” control from unit.

9. Remove the 3 wires from the heating elements.
Figure 1-6.

If element terminals look heavily corroded, remove the

wires at the contactor instead of the elements. Remove
the wires from the mercury contactor, from the kit, and
pull the amp rings from the wires. Slide the appropriate

Figure 1-6 colored ring over the line wire and attach to mercury

contactor. See below. Black=L1 Red=L2 Orange=L3 Using a wire tie, fasten each ring up on the line wire, so it doesn’t slide down against the contactor terminal.

3. Install 2 sheets of insulation against frypot wall, thin
sheet first. Figure 1-10.

4. Locate the wire harness with the 6-pin red connector.
a. Connect the yellow wires to high limit wires using
wire nuts.
b. Connect the white wires to the drain switch wires
using wire nuts. Figure 1-11.

5. Install contactor assembly from kit. Figure 1-12.

6. Connect the solenoid wires to the red wires in positions
1 & 2 of the 12-pin connector.

connect the wires to the pump wires.

Be sure to connect these to the pump wires and NOT

the pressure solenoid wires, or the 24V pressure
solenoid coil will be damaged when the pump is
turned on.

8. Install the two threaded standoffs in the lower holes,
where the front panel mounting screws were removed.
Tighten the nuts on the threads on the back side of the
sheet metal to prevent the standoffs from turning.
Figure 1-13.

Figure 1-13 9. Wire tie the wires to keep them from interfering with

the components, except for the probe and amp
monitoring connector. Pull the wires to the left side of
the controls, but don’t bundle the power switch wires
with the others for ease of panel removal.

10. Plug all connectors, including the probe and new
transformer harness into the back of the control.

The connector from the transformer can plug into two

connectors on the control. This is to select the voltage
tap on the transformer for 208V or 240V. Determine
the proper voltage and insert the plug into that
connector.

11. Secure the panel into place with screws previously

removed.

12. Supply power to the fryer and program the low amp
setting in Special Program Mode. (Power switch off)

The Computron 8000 controls monitors the amperage

to the elements. The nominal amp setting must be
programmed after installation and before operation, or
a constant warning shows on the display when the

controls are turned on.

a. Press and hold for 5 seconds until

"L-2" and "LEVEL 2", followed by, “SP PROG"
and “ENTER CODE shows in the display.
b. Enter code 1, 2, 3, and "SP- 1 ", "TEMP, UNITS"
shows in the display.
c. Press until “SP-12”, “AMPS RDG,

NOMINAL” shows in display.
d. Check the amp reading on the right side of display
(ex: “37 A”) with the amp reading on the data
plate. If readings are different, use to
change display to match data plate.

e. Press and hold to exit Special Program Mode

and unit is now ready for operation.

Upon initial start-up “CLOCK SET” shows in display. Set
the clock to your time, following prompts on the display, or
see section 2-2 in Operating Instructions for help.

Then display asks if the peanut oil is NEW or OLD. The
controls automatically adjust the peanut oil temperature to
the age of the peanut oil. If the oil is old, use to set
the number of days of old peanut oil.

Set Nominal Voltage

The controller continually monitors the line voltage supplied
to the fryer (when the fryer is on). If the line voltage drops
below [90%] of its nominal value, the controller signals a
“LOW VOLTAGE” alarm. Also, once the voltage is set, the
controls automatically set the nominal amperage value. This
nominal voltage value must be programmed after retrofit
installation to avoid nuisance alarms.

1. Press and hold for 5 seconds until “L 2 LEVEL 2”
shows in the display. Then release 5 times until
“TECH” shows in the display.

2. Enter code 1, 1, 2, 2, 1, 1, 2, 2.

3. Press and release 10 times until “T-11” shows in
the display.

4. Use to match the displayed value with the

voltage showing on the data plate, on the door of the
fryer.
