SECTION 1. INTRODUCTION

Model 500/600

1-1. INTRODUCTION

The Henny Penny pressure fryer uses a combination of pressure,
heat, and time to produce a quality product. The advantage of this
type fryer is the pressure allows the product to be cooked with less
heat and less time than the conventional open-type fryers.

The Chick-fil-A controls for the Henny Penny Models 500 (elec­tric) and 600 (gas) have many features to allow the Operator to
produce consistent, quality products. The controls monitor not
only cooking times and temperatures, but also peanut oil condition,
product weights, product temperatures, and many other operational
variables. The controls may vary the actual peanut oil temperature
and cook times, based on changes of the operational variables.

The controls also have very extensive self-diagnostic functions
which alert the Operator to both component and procedure
problems.

Some unique features of the fryer are listed below:

• Diagnostic function-provides summary of fryer and

Operator performance. See Diagnostic Mode and Special
Functions Section.

• Alarms and error messages-provide immediate feedback for

Operator error or fryer malfunction. See W arnings and Error
Messages Section.

• Status Mode-allows the Operator to view basic fryer informa-

tion and status. See Diagnostic Mode and Special Functions
Section.

• Information Mode-gathers and stores historic information on

the fryer and Operator performance, and can be viewed by the
Operator. See Diagnostic Mode and Special Functions Section.

• Oil Filter enforcement-prevents the Operator from exceeding

approved number of Cook Cycles before filtering the peanut oil.
See Diagnostic Mode and Special Functions Section.

• Manual Program Mode-Operator can set time and tempera-

ture for nonstandard products. See Diagnostic Mode and Special
Functions Section.

• Easy toggle between English and Spanish operation. See

Diagnostic Mode and Special Functions Section.

• Clean-Out Mode-a preprogrammed function for cleaning the

frypot. See Cleaning the Frypot Section.

14. Prepare deadweight valve assembly for operation.

A metal shipping support is installed inside the dead­weight valveassembly and must be removed prior to
installation and startup,or unit will NOT build pressure.

15. Unscrew the deadweight cap.

16. Remove the deadweight.

17. Remove and discard the shipping support.

18. Clean the deadweight orifice with a dry cloth.

19. Replace the deadweight and secure the deadweight cap.

20. Remove the protective paper from the fryer exterior and clean

with the surfaces with a cloth, soap and water.

2-3. SELECTING THE
FRYER LOCATION

The proper location of the fryer is very important for operation,
speed, and convenience. Choose a location which provides easy
loading and unloading without interfering with the final assembly of
food orders. Operators have found that frying from raw to finish, and
holding the product in warmers, provides fast continuous service.
Landing or dumping tables should be provided next to, at least, one
side of the fryer. Keep in mind the best ef ficiency will be obtained by
a straight line operation, i.e., raw in one side and finished out the other
side. Order assembly can be moved away with only a slight loss of
efficiency . T o properly service the fryer , 24 inches (60.96 cm) of
clearance is needed on all sides of the fryer. Access for servicing can
be attained by removing a side panel. Also, at least 6 inches (15.24
cm) around the base of the gas units is needed for proper air supply
to the combustion chamber.

To avoid a fir e, install the fryer with minimum clearance
from all combustible and noncombustible materials, 6 inches
(15.24 cm) from side and 6 inches (15.24 cm) from back. If
installed properly, the gas fryer is designed for operation on
combustible floors and adjacent to combustible walls.

To avoid fir e and ruined supplies, the area under the fryer
should not be used to store supplies.

710 2-3

2-3. SELECTING THE
FRYER LOCATION
(Continued)

Model 500/600

T o prevent sever e burns from splashing hot shortening,
position and install fryer to prevent tipping or movement.
Restraining ties may be used for stabilization.

2-4. LEVELING THE FRYER

2-5. VENTILATION OF
FRYER

For proper operation, the fryer should be level from side to side
and front to back. Place a level on the flat areas around the frypot
collar, then adjust the leveling bolts or casters until the unit is level.

FAILURE TO FOLLOW THESE LEVELING INSTRUC­TIONS CAN RESUL T IN SHOR TENING OVERFLOW ­ING THE FR YPOT WHICH COULD CAUSE SERIOUS
BURNS, PERSONAL INJUR Y , FIRE, AND/OR PROP­ERTY DAMAGE.

The fryer must be located with provision for venting into adequate
exhaust hood or ventilation system. This is essential to permit efficient
removal of the flue gases and frying odors. T ake special precautions
in designing an exhaust canopy to avoid interference with the opera­tion of the fryer. W e recommend you consult a local ventilation or
heating company to help in designing an adequate system.

V entilation must conform to local, state, and national codes.
Consult your local fire department or building authorities.

When installing the gas fryer do not attach an extension to
the gas flue exhaust stack. This may impair proper opera­tion of the burner, causing malfunctions and possible nega­tive backdraft.

2-6. GAS SUPPL Y

The gas fryer is factory available for either natural or propane gas.
Check the data plate behind the front door of the fryer to determine
the proper gas supply requirements.

Do not attempt to use any gas other than that specified
on the data plate. Conversion kits can be installed by
your distributor if required. Incorrect gas supply could
cause an explosion or fire resulting in severe injuries
and/or property damage.

Please refer below for the recommended hookup of the fryer to main
gas line supply .

T o avoid possible serious personal injury:

• Installation must conform with American National S tandard
Z223.1 - (the latest edition) National Fuel Gas Code and
the local municipal building codes. In Canada, installation
must be in accordance with Standard CSA Bl49-& 2,
Installation Codes Gas Burning Appliances, and local
codes.

• The fryer and its individual shut-off valve must be discon­nected from the gas supply piping system during any
pressure testing of that system at test pressures in excess
of 1/2 PSIG (3.45 KP A)(34.47 mbar).

• The fryer must be isolated from the gas supply piping
system by closing its individual manual shut-off valve
during any pressure testing of the gas supply piping system
at test pressures equal to or less than 1/2 PSIG (3.45 KPA)
(34.47 mbar).

• A standard 3/4 inch, black steel pipe and malleable fittings
should be used for gas service connections.

• Do not use cast iron fittings.

• Although 3/4 inch size pipe is recommended, piping should
be of adequate size and installed to provide a supply of gas
sufficient to meet the maximum demand without undue loss
of pressure between the meter and the fryer. The pressure
loss in the piping system should not exceed 0.3 inch water
column (0.747 mbar).

2-6 803

Model 500/600

2-6. GAS SUPPL Y (Continued)

Provisions should be made for moving the fryer for cleaning and
servicing. This may be accomplished by:

1. Installing a manual gas shut off valve and disconnect union, or

2. Installing a heavy duty design A.G.A. certified connector which
complies with the Standard for Connectors for Moveable Gas
Appliances, ANSI Z21.6, or CAN/CSA 6.16, with a quick­disconnect coupling (Henny Penny Part No. 19921), which
complies with ANSI standard Z21.41, or CAN 1-6.9. Also
adequate means must be provided to limit the movement of the
fryer without depending on the connector and quickdisconnect
device or its associated piping to limit the fryer movement.

3. See the illustration on the following page for the proper connec­tions of the flexible gas line and cable restraint.

The cable restraint limits the distance the fryer can be pulled from
the wall. For cleaning and servicing the fryer, unsnap the cable
from the unit, and disconnect the flexible gas line. This allows
better access to all sides of the fryer. The gas line and cable
restraint must be reconnected once the cleaning or servicing is
complete.

2-7. GAS LEAK TEST

Prior to turning the gas supply on, be sure the gas valve knob
on the gas control valve is in the OFF position.

After the piping and fittings have been installed, check for gas leaks. A
simple checking method is to turn on the gas and brush all connec­tions with a soap solution. If bubbles occur, it indicates escaping gas.
In this event, the piping connection must be redone.

T o avoid fire or explosion, never use a lighted match or
open flame to test for gas leaks. Ignited gas could result in
severe personal injury and/or property damage.

Safety Relief Valve

This reservoir holds the peanut oil, and is designed to hold
12 lb (5.4 kg) of product, with a “cold zone” for collection of crumbs

Provides the pressure seal for the frypot chamber

The deadweight style, pressure relief valve maintains a constant level of
operating steam pressure within the frypot; excess steam is vented
through the exhaust stack. (See Figure 3-1)

Failure to clean the deadweight assembly daily could result in
the fryer building too much pressure. Severe injuries and
burns could result.

An ASME approved, spring loaded valve, set at 14.5 psi; in the event
the deadweight valve becomes clogged, this safety valve releases
excess pressure, keeping the frypot chamber at 14.5 psi; if this occurs,
turn the COOK/PUMP switch OFF to release all pressure from the
frypot. (See Figure 3-1)

If safety relief valve activates, turn main power switch
to the OFF position. To avoid serious burns and injuries,
have fryer serviced before next use.

Hot shortening must always be at the upper level indicator line
(Figure 3-4). Failur e to follow these instructions could r esult in
a fire and/or damage to the fryer.

When using solid shortening, it is recommended to melt
the shortening on an outside heating source before placing it in
the frypots. The elements on electric fryers must be completely
submerged when power is turned on. Fire or damage to the
frypot could result.

Figure 3-4

1. Henny Penny recommends using a high quality frying peanut oil in
the pressure fryer. Some low grade peanut oils have a high mois­ture content which causes foaming and boiling over .

T o avoid severe burns when pouring hot shortening into
frypot, wear gloves and take care to avoid splashing.

2. The electric model requires 48 lbs (21.8 Kgs) of peanut oil. The
frypot has 2 level indicator lines inscribed on the rear wall of the
frypot, and the heated peanut oil is at the proper level when it’ s at
the upper indicator line. Figure 3-4.

3. Cold peanut oil should be filled to 1/4 to 1/2 inch below the upper
indicator line on electric units. The peanut oil expands when heated
and should be even with the upper indicator line when the peanut oil
is at cooking temperature.

3-7. BASIC OPERA TION

The following procedures should be followed on the initial start-up of
the fryer, and each time the fryer is brought back into operation from a
cold or shut down condition. These are basic, general instructions.

1. Check to see that the COOK/PUMP switch is turned OFF .

2. Make sure the drain valve and filter valve are closed.

3. Remove the fry basket from the frypot and leave lid up.

4. Make sure the peanut oil is filled to the proper level in the frypot;
1/4 to1/2 inch (6.4-12.7 mm) below level indicator line. See
Filling or Adding Peanut Oil Section.

5. Connect power to the fryer .

6. On gas models, light the pilot light. Refer to Gas Pilot Lighting
Procedures Section.

7. Turn the COOK/PUMP switch to COOK. Upon initial start-up

“CLOCK SET” shows in display . Set the clock to your time,

following prompts on the display , or see section 3-3 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. Use to set the number of days of old peanut oil.

8. Unit automatically goes into the Melt Cycle, until the peanut oil
temperature reaches 230°F (110°C). Then the controls go into
the Heat Cycle and the peanut oil heats to a preset temperature.

Once melted peanut oil reaches the proper level in the frypot,
the melt cycle can be bypassed by pressing and holding one of
the Product buttons.

Do not bypass the Melt Cycle unless enough shortening
has melted to completely cover the elements in electric fryers
or frypot surface in gas fryers. If the Melt Cycle is bypassed
before all surfaces are covered, excessive smoking of
shortening, or a fire will r esult.

9. Stir the peanut oil as it is heating up from a cold start. Be sure to
stir down into the bottom of the frypot.

3-7. BASIC OPERA TION

(Continued)

10. Once out of the Melt Cycle, flashes until 5° before setpoint

temperature ( plus any offset temperature). Then lights
and the selected product shows on the display .

The heat cycles on and off about 4 degrees before the setpoint
temperature to help prevent overshooting the setpoint temperature
(proportional control).

11. If the peanut oil was not filtered the night before at shutdown,
filter the peanut oil now . Refer to Filtering Instructions Section.

12. Follow the steps in Chick-fil-A ’ s training materials to load the
product.

Before loading product, make certain is lit, indicating

that the peanut oil is at the correct cooking temperature
for the type of product being cooked. The actual temperature
may vary 20 degrees or more depending upon peanut oil age,
product weights, product temperature, and other operational
variables.

Be certain the shortening is never above the level indicator
line. The maximum load size is 12 lbs. (5.4 kg.) for model
600 fryers; 14 lbs (6.4 kg.) for model 500 fryers. Failure to
follow these instructions could result in a fir e and/or damage
to the fryer.

13. Close the lid quickly, latching the lid.

14. Tighten the lid spindle clockwise, sealing the lid. Align the red
knob on the spindle with the red knob on the latch.

Do not press a product button until lid is sealed, or the lid will
try to lock as it is being tightened down.

3-8. CARE OF PEANUT OIL

19. 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
peanut oil.

Do not let the lid slam up against its backstop because
this could damage the hinge.

20. Follow the steps in Chick-fil-A’s training materials to unload the
product and check for doneness.

After the Cook Cycle, if the product needs to cook more, place
basket back into frypot and press for an additional 45 seconds.

21. Before frying next load, allow for the peanut oil to reheat and
lights.

FOLLOW THE INSTRUCTIONS BELOW TO AVOID
SHORTENING OVERFLOWING THE FRYPOT, WHICH
COULD RESULT IN SERIOUS BURNS, PERSONAL
INJURY, FIRE, AND/OR PROPERTY DAMAGE.

1. Frying breaded products requires filtering to keep the peanut oil
clean. The peanut oil should be filtered after every 5 Cook Cycles
for electric fryers, and after every 4 Cook Cycles for gas fyers.
Refer to Filtering Instructions Section.

2. Maintain the peanut oil at the proper cooking level. Add fresh
peanut oil as needed.

3. Discard peanut oil if display shows “CHANGE OIL SOON” or if
peanut oil shows signs of excessive foaming or smoking.

4.

Do not overload the baskets with product (12 lbs. (5.4 kg.) for
model 600 fryers; 14 lbs (6.4 kg.) for model 500 fryers, or place
product with extreme moisture content into baskets.

WITH PROLONGED USE, THE FLASHPOINT OF
SHORTENING IS REDUCED. DISCARD THE
SHORTENING IF IT SHOWS SIGNS OF EXCESSIVE
SMOKING OR FOAMING, OR SERIOUS BURNS,
PERSONAL INJURY, FIRE, AND/OR PROPERTY
DAMAGE COULD RESULT.

3-9. FIL TERING OF

SHORTENING

At the end of the preset number of Cook Cycles (5 for electric; 4 for
gas), an alarm sounds and “FIL TER LOCKOUT” then “YOU *MUST*

TER NOW” shows in the display . No Cook Cycles can be started

FIL

until the peanut oil is filtered (The controls show how many cycles until
next filtering, ex: “5X” in display .)

Chick-fil-A ’ s training materials outline two methods of filtering the oil: a
Quick Clean and a Thorough Clean. The Thorough Clean includes all the
steps below (#1-10), whereas the Quick Clean omits step #6. Follow the
steps in Chick-fil-A ’ s training materials when filtering the oil.

1. Turn the COOK/PUMP switch to OFF and remove basket.

The best results are obtained when the shortening is filtered at the
normal frying temperature.

2. Using a metal spatula, scrape any buildup from the sides of the
frypot. Do not scrape heating elements on electric units or the
curved surface of the gas frypot.

Drain Valve
Handle

Figure 3-6
(Electric Model)

Filter Valve
Handle

Scraping the electric fryer elements, or the curved portion
of the gas frypot, produces scratches in these surfaces
causing breading to stick and burn.

The filter drain pan must be as far back under fryer as it will
go, and the cover in place. Be sure the hole in the cover
lines up with the drain before opening the drain. Failure to
follow these instructions causes splashing of peanut oil and
could result in personal injury .

Also, when using a crumb basket, it must be emptied as
required and positioned properly under the drain valve to
prevent splashing of hot peanut oil and severe burns.

Surfaces of fryer and basket will be hot. Use care when
filtering to avoid burns.

3. T urn the left drain handle counterclockwise half a turn first,
then slowly to the full open position (handle pointed down for
electric models and pointed up for gas models). This helps
prevent splashing of hot peanut oil. Figure 3-6.

4. As the peanut oil drains from the frypot, use fryer brushes (Henny
Penny part no. 12105-includes both brushes) to clean the frypot
and heating elements (if electric unit). Use L-shaped brush to
clean crumbs from the elements and from sides and bottom of
frypot as peanut oil drains. Use poker brush to push crumbs
through drain opening in bottom of frypot, if necessary .

5. When all peanut oil has drained, scrape or brush sides of frypot.

6. Rinse the frypot as follows:
a. Attach the filter rinse hose to the quick-disconnect fitting, inside

the door, next to the filter valve handle. Slide the collar back on
the quick-disconnect fitting on the hose, push it onto the unit’s
fitting and let it snap into place. Figure 3-7.

b. While holding the wooden handle, make sure the hose nozzle

is pointed down into the bottom of the frypot. Pull the lid
down over the nozzle, close the filter valve, and move the
COOK/PUMP switch to the PUMP position. Hold nozzle
carefully to avoid excessive splashing. Figure 3-8.

Figure 3-8

Use caution to prevent burns caused by splashing hot
peanut oil.

c. Rinse the frypot interior, especially areas like the frypot bottom.

On electric models, rinse around heating elements.

d. After sufficient rinsing, turn the left drain valve handle clockwise

to close the drain valve (handle pointed horizontally).

e. Turn the COOK/PUMP switch to OFF .

7. Turn the right filter valve handle counterclockwise to open the filter
valve (handle pointed horizontally). Turn COOK/PUMP switch to
PUMP and pump all peanut oil out of the filter drain pan and back
into frypot, holding the lid closed for the first surge of peanut oil.

8. When the pump begins creating air bubbles in the peanut oil, all of
th e peanut oil should be out of drain pan. First, turn the right filter
valve handle clockwise to close the filter valve (handle pointed
up). Then turn the COOK/PUMP switch to OFF. This keeps the
filter pump and lines from filling with peanut oil.

When air bubbles appear in peanut oil, immediately close the
filter valve. This will prevent aeration of the shortening, therefore
increasing shortening life.

9. After completing the filtering operation, empty and replace the
condensation drain pan.

10. If frying is to be continued, turn the COOK/PUMP switch to
COOK and allow peanut oil to heat until lights.

3-10. FIL TER PUMP
PROBLEM
PREVENTION

The following steps will help prevent filter pump problems.

1. Make certain the filter paper envelope is properly installed over
the filter screens. Make sure the open end of the envelope is
properly folded and clamped in place with the retaining clips so
crumbs cannot enter the envelope. See Changing the Filter
Envelope Section.

2. The filter valve is to be closed at all times during frying.

3. Make sure all peanut oil has been pumped from the filter lines and
the pump by allowing the filter pump motor to run until air bubbles
appear in the peanut oil.

3-13. CLEANING THE

FRYPOT

After the initial installation of the fryer, as well as before every change of
peanut oil, the frypot should be thoroughly cleaned as follows:

1. Turn the COOK/PUMP switch to OFF .

Moving either the frypot, or filter pan, while containing hot
shortening is not recommended. Hot shortening can splash
out. Severe burns could result.

The filter drain pan must be as far back under the fryer as it
will go, and the cover in place. Be sure the hole in the cover
lines up with the drain before opening the drain. Failure to
follow these instructions causes splashing of shortening and
could result in personal injury .

2. If hot peanut oil is present in the frypot, turn the left drain handle
counterclockwise half a turn first, then slowly to the full open
position (handle pointed down for electric models, and pointed up
for gas models).

3. Turn the left drain valve handle clockwise to close the drain valve
(handle pointed horizontally) and discard the peanut oil. Then
install filter drain pan under the fryer, leaving out the filter screens.

4. Follow the directions in Chick-fil-A ’s training materials and fill the
frypot to the level indicator line with cleaning solution.

Always wear chemical splash goggles or face shield and
protective rubber gloves when cleaning the frypot as the
cleaning solution is highly alkalie. Avoid splashing or other
contact of the solution with your eyes or skin. Severe burns

and possible bindness will result. Carefully read the instruc­tions on the cleaner . If solution comes in contact with your
eyes, rinse thoroughly with cool water and see a physician
immediately.

Model 500/600

4-6. LIMIT STOP

ADJUSTMENT

Step 2

T o extend the life of the lid gasket and help prevent steam
leakage, check the limit stop adjustment quarterly , following the
steps belo

w:

1. Close and latch lid, and turn spindle counterclockwise until

it stops.

2. Using a 3/16” Allen wrench, loosen the 2 set screws on the

outer collar of the limit stop.

3. Turn the inner collar clockwise until it stops.

Insert a small screwdriver or Allen wrench in the hole in the
inner collar to assist you in turning the collar.

4. Turn spindle clockwise until it stops. The lid gasket is now

touching the frypot rim.

5. From the front of the fryer, turn the spindle at least 3/4 of a

turn, but not over 1 turn. One of the spindle arms should be
lined up with the red ball of the latch, at this time.

Step 3

6. Slightly turn the spindle past this position, so it should show in

about the 7 o’clock position.

The 7 o’clock position is only to allow slight additional turning
of the spindle to relieve any side pressure against the locking
pin. Side pressure holds the pin in the locked position, even
after all the pressure has released.

When adjustment is complete, if a black ball on the spindle is
lined up with the red ball on the latch, unscrew the black ball
and the red ball on the spindle and change places on the
spindle. The red ball on the spindle should now line up with
the red ball on the latch.

7. Turn the inner collar counterclockwise until it stops against the

bottom hub of the spindle.

8. Tighten Allen screws.

If the lid cover fails to seal properly , steam escapes from
around the gasket during frying. Readjust the limit stop, this
time turning the spindle 1 full turn after the initial contact of the
lid gasket with the frypot rim (step 5).

D 2: Oil W ear Report

This section displays information about the age of the present batch of
peanut oil.

The first step shows how many days of use this oil has:

“D2: THIS OIL IS “
“D2: 4 DA YS OLD “

The controller only counts days in which the fryer is in use.

Press to move on to the second step. This step shows the age of

the peanut oil by percentage of its expected lifetime. The peanut oil’ s
present, accumulated wear is compared to the wear setting at which the
controller will prompt for the oil to be changed.

“D2: THIS OIL IS “
“D2: 16% USED “

This information can be used as the oil nears the end of its life (i.e.
95%), to plan ahead for when a clean-out will be required.

D 3: Line V oltage Performance Report

This section displays information about how good the line voltage
supply has been for the present day and for the present batch of oil.

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 VOL T AGE” alarm. This
alarm sounds at the end of each Cook Cycle for which low voltage has
been detected. While not cooking, the low voltage alarm can sound as
frequently as every 30 minutes.

“[ ]” around a value, such as [90%], means this value is

programmable and might change with later software versions.

V oltage Report for T oday

If no low voltage warnings have been detected for the present day , the

D 4: Heating Capacity Report

This section reports the present status of the heating system.

The controller examines a history of heat-up data and determines
whether or not the heating system is operating normally . The heat
capacity is said to be bad only if the most recent heat-up failed to meet
the expected heat-up rate and three of the last four heat-ups also failed
to achieve the expected rate. That is, a single slow heat-up will not
trigger a slow heat warning. The slow heat warning is activated only
after repeated low-rate heat-ups is observed.

The controller can’t assess the integrity of the heating system if the fryer
has been experiencing voltage problems. Low heat rates observed in
this situation might be due to voltage problems rather than heater
problems.

D 5: Cook Times (Slow Cooks) Report

This section summarizes the slow cooking status for each product.

Actual cook times for Cook Cycles can vary from the programmed
cook time setting, due to the load compensation feature. Load
Compensation slows the cook timer down when the actual peanut oil
temperature is below a reference value, and speeds up the cook timer
countdown when peanut oil temperature is above the reference.

When the peanut oil temperature is lower than expected during a Cook
Cycle, the overall cook time will be longer than normal. If the actual
cook time stretches beyond a programmed limit, the controller counts a

“SLOW COOK” event and sounds an alarm at the end of the Cook

Cycle.

If low voltage or low amps are detected during the Cook Cycle, the
warning message indicates “LOW VOL T AGE” or “LOW AMPS”, but
the cycle will still count as a “slow cook”. If the voltage and amps have
been fine during the Cook Cycle but the cycle was started before the
Ready light came on, then the warning message indicates “SLOW

COOK —

W AIT FOR READY LIGHT”. Otherwise, the slow

cooking problem will be attributed to a “bad batch” of product: cooking
too much in one load, or cooking product that is too cold (i.e. frozen
product on a pressure fryer when the product should be fresh).

If none of the products has more than 5% slow Cook Cycles today , the
following report is made:

“D5: COOK TIMES”
“D5: LOOK OK”
“D5: TODA Y”

303 5-17

5-3. DIAGNOSTIC MODE
DETAILS (Continued)

Otherwise, if one or more cook products have generated a slow cook
warning more than 5% of the time, but four or more low voltage or slow
heat-up warnings (any combination) have been generated today , then
the report is as follows:

“D5: SOME SLOW”
“D5: COOKS TODA Y”
“D5: MA YBE DUE TO”
“D5: VOL T AGE OR”
“D5: COIL PROBLEMS”

Such a report is saying the slow cooking may be the result of low
voltage (which significantly reduces heat capacity) or the result of other
problems with the heating system. In this case, the slow cook problems
might not have anything to do with user error.

Otherwise, the slow cooking is generally attributed to user error:
cooking too much product in one load, cooking frozen product (in the
pressure fryer) when it should be fresh, or cooking before the Ready
light illuminates, etc.

An individual “XXXXX IS COOKING SLOWL Y TODA Y” report
item is generated for each product that has had more than 5% slow
cook warnings today . This report item is triggered based solely on the
number of slow cooks for that product, whether those slow cooks are
due to voltage or heating problems, or due to cooking before ready ,
cooking too much, or cooking frozen product.

If the fryer was in the ready range when the user begins to load product,
but is out of the ready range by the time the Cook Cycle is started, the
control will not give you an alarm.

If the fryer wasn’t ready before loading, an alarm sounds and “WAS

D 7: “Stopped Too Soon” Report

This section shows how many Cook Cycles were stopped early by the
user, before the cook timer had counted down to 0:00 and the

“*DONE*” indication was given. This is strictly a user error .

Cycles that are canceled after cooking for less than 30 seconds are not
counted here. For example, if a cycle is accidentally started, and the
Cook Cycle is canceled after just a few seconds, this cycle will not be
counted as a Stopped T oo Soon Cycle.

Also, some allowance is given for stopping a cycle a little early . The
user can cancel the cycle up to 10 seconds early without penalty .

Otherwise, however, any cycle that was stopped with more than 10
seconds remaining (0:10) on the cook clock with be counted as a

D 9: Irregular Loading Report

For most Cook Cycles, the controller determines when the product was
placed into the peanut oil. This report identifies the percentage of
cycles for which this determination was not successful.

This drop detection detects most loads, but can fail for several reasons.
Anytime the detection routine fails to find the true drop point, the
controller logs an irregular loading count.

Examples of failed drop detection might be: the Operator takes too long
to load the product to the time he presses the start button, or the
Operator cooks a very light product load, one or two filets, for
example.

In these instances, no drop point will be found and that Cook Cycle
counts as an Irregular Loading Cycle. Only products that have more
than 5% of loads with missed detection’ s are reported.

D 10: Non-Standard Pr ogram Items Report

The last section in the diagnostic report identifies how many
programmable settings have been altered from their original, factory
default settings.

For each of the various program modes, the controller either reports
that all settings match original values or reports N items do not match
original values. This report makes it easy to see if any cook parameters
or other settings have been changed from CF A settings.

Some programming items may have been changed from original values
under the direction of CF A corporate headquarters. In some cases, a
controller should have values that don’ t match original values. A report
that “all items match original values” could actually be an indication that
something isn’t set right.

Keep in mind also that the number of such approved alterations might
be different for different versions of software.

If all product cook settings match the original, factory default values, the
controller displays the following message:

“10: ALL PROD’S”
“10: MA TCH”
“10: ORIG . VALUES”

message is displayed (with one or more of the product numbers
blinking):

“10: PROD’S 123456”
“10: DO NOT MATCH”
“10: ORIG . VALUES”

In this case, the blinking numbers indicate which products do not match
original settings. If the numbers 3 and 5 are the only numbers blinking,
then product #3 and product #5 each have at least one setting changed
from their factory preset values. Products 1, 2, 4, and 6 are confirmed
to exactly match their original settings.

The second item in D 10 identifies how many items in CF

A
Programming Mode have been changed from their original values.
These Chick-fil-A settings mainly deal with special Chick-fil-A
controller features like oil wear, heat-up monitoring, new oil
compensation, oil idle compensation, drop detection, amps and voltage
alarms, and Clean-out Mode.

If all items in CF A Prog Mode match their original, factory preset

the heaters. (These sensors are not present on gas fryers.)

On pressure fryers, these values indicate the current through each
supply leg to the heaters. These values do not correspond directly to
the current through an individual heater coil.

The amps values should normally cycle on and off with the heat light,
and all three values should be about the same.
