1-5. BASIC OPERATIONS These are just basic procedures. Refer to the fryer Operator’s
AND PROCEDURES
Manual for more detailed instructions.
1. Be sure the drain valve is in the closed position.
2. Remove fry basket from frypot and leave lid up.
3. Fill the frypot with shortening.
When using new shortening, it is recommended to
melt the shortening on an outside source before
placing shortening in the frypot. Unless elements are
completely covered in shortening, fire or damage to
the frypot could result.
4. Move power switch to the COOK position. Unit
automatically goes into the Melt Cycle. When the
temperature reaches 230°F (110°C) the control goes
into the Heat Cycle, and heats the shortening until the
temperature setting is reached.
Bypass the Melt Cycle, if desired, by pressing a product
button and holding it for five seconds. The display
shows “EXIT MELT? 1=YES 2=NO”. Press
to exit melt.
If the melt cycle is bypassed on fryers with the Frypot
Protection System (FPS), the unit continues to heat as
controlled by the FPS. No change in heat-up time will
be observed.
Do not bypass the Melt Cycle unless enough
shortening has melted to completely cover all of the
heating elements, or the curved surface of the gas
frypot. If Melt Cycle is bypassed before these surfaces
are covered, excessive smoking of the shortening or a
fire will result.
5. Once out of the Melt Cycle, flashes until
5°F (3°C) before setpoint temperature is reached.
Then illuminates and the selected product shows
in the display.

throughout the frypot.
7. Once the shortening temperature has stabilized at the
setpoint temperature, place the baskets into the
shortening. Then place product into the basket.
Do not overload, or place product with extreme
moisture content into the basket. 18 lbs. (8.2 kgs)
for the 561 and 12 lbs. (5.4 kgs) for the 500 and
600, is the maximum amount of product per frypot.
Failure to follow these directions can result in
shortening overflowing the frypot. Serious burns or
damage to the frypot could result.
8. Lift the basket slightly out of the shortening and shake
basket to separate pieces.
9. Remove basket handle and close lid quickly, latching
the lid.
10. Tighten the lid spindle clockwise, sealing the lid. Align
red knob on the spindle with red knob on the latch.
LATCH THE LID PROPERLY AND ALIGN THE
RED BALLS OR SEVERE BURNS WILL
RESULT.
11. Press to start a Cook Cycle.
The display counts down the cooking time.
A different product can be selected during the first
minute of cooking, in case the wrong product button
was pressed. To check the shortening temperature
press or to stop a Cook Cycle, press .

DO NOT ATTEMPT TO OPEN LID UNTIL THE
PRESSURE DROPS TO ZERO. LID IS LOCKED
WHEN FRYER IS UNDER PRESSURE. DO NOT
ATTEMPT TO FORCE THE LID LATCH OR OPEN
THE LID WHILE UNDER PRESSURE. OPENING
THE LID WHEN THE FRYPOT IS PRESSURIZED
ALLOWS HOT SHORTENING AND STEAM TO
ESCAPE FROM THE FRYPOT, RESULTING IN
SEVERE BURNS.
14. After pressure drops to zero, turn the spindle counter-
clockwise.
Do not flip or spin the spindle cross arm when
opening the lid because it could damage the acme nut
inside the cross bar.
15. Unlatch and raise the lid quickly to allow most of the
condensation on the lid to drain through the drain
channel and not into the shortening.
Do not let the lid slam up against the backstop
because damage to the hinge could result.
16. Using the detachable handle, lift the basket and inspect
product for doneness. Dump product into holding pan.
17. If a Quality time (hold time) was programmed, the
controller automatically starts the hold timer. The
display alternately shows the product selected and the
quality time remaining in minutes. If a different
product is selected during the Hold Cycle, the display
only shows the product selected.

In the Cook Mode, when “FILTER SUGGESTED”,
shows in the display, the operator has the option to
filter at this time, or to continue cooking. But, if the
operator continues cooking, a Filter Lockout occurs
within the next Cook Cycle, or two.
The shortening continues to heat when filter lockout occurs.
If the shortening temperature is below the preset temperature
in the Special Program Mode (SP-8C or SP-8D), a tone
sounds and “FILTER LOCKOUT”, and then “WAIT” shows
on the display. Once the shortening temperature reaches the
preset temperature, "FILTER LOCKOUT" , and then "YOU
*MUST* FILTER NOW........” shows in the display and the
shortening can now be filtered. During filter lockout,
is the only button that functions, until the unit is filtered.
Follow the steps in the 500/561/600 Operator’s Manual on
filtering.
1-6. CLEAN-OUT MODE
The Computron 8000 has a Clean-Out Mode to clean the
frypot upon initial start-up and every change of shortening.
Follow the steps in the 500/561/600 Operator’s Manual on
Cleaning the Frypot.
When heating the cleaning solution and vinegar solutions,
turn the COOK/PUMP switch to COOK. When the fryer
starts the Melt Cycle, press and hold then
“CLEAN-OUT ?”, “1=YES 2=NO” shows in display. Press
to start Clean-Out Mode. The fryer displays
“*CLEAN-OUT MODE*” and heats up to a preprogrammed
temperature, up to 195˚F (91˚C), then automatically begins a
preset timed countdown. Use the buttons, if
necessary, to adjust the temperature and keep the cleaning
solution from boiling over. See Special Program Modes
SP-10 and SP-11 to preset the temperature and time.
