SECTION 3. OPERATING INSTRUCTIONS
3-1. OPERATING CONTROLS
COOK/PUMP Switch A three-way switch with center OFF position; move the switch to
the position marked COOK to operate the fryer; move the switch
to the PUMP position to operate the filter pump; certain conditions
must be met prior to operation of the filter pump; these conditions
are covered later in this section
Frypot This reservoir holds the cooking shortening, and is designed to
accommodate the heat exchanger, 8 head of product, and an
adequate cold zone for collection of cracklings
Carrier This stainless steel carrier consists of five racks which contain
the food product during and after frying
Lid Gasket Provides the pressure seal for the frypot chamber
Deadweight Valve The deadweight style operating pressure relief valve is used to
maintain a constant level of steam pressure within the frypot;
any excess steam pressure is vented through the exhaust stack;
remove the deadweight cap, and clean the deadweight cap,
weight, anddeadweight orifice once a day; see Section 3-15
Failure to clean the deadweight assembly daily could
result in the fryer building too much pressure. Severe
injuries and burns could result.
Safety Relief Valve An ASME approved spring-loaded valve set at 14.5 psi
(999 mbar); in the event the operation valve becomes obstructed,
this safety valve will release excess pressure, keeping the frypot
chamber at 14.5 psi (999 mbar); if this occurs, turn the COOK/
PUMP switch to the OFF position to release all pressure from the
frypot
Safety Relief Valve Ring
This ring is not to be pulled
SEVERE BURNS FROM THE STEAM WILL RESULT.

3-1. OPERATING CONTROLS
(Continued)
Pressure Gauge Indicates the pressure inside the frypot
Solenoid Valve An electromechanical device that causes pressure to be held in the
frypot
The valve closes at the beginning of the Cook Cycle and opens
automatically at the end of the Cook Cycle; if this valve should
become dirty or the Teflon seat nicked, pressure will not build up
and it must be repaired per the Technical Manual maintenance
procedures
Drain Valve A two-way ball valve; it is normally in the closed position; turn the
handle to drain the shortening from the frypot into the filter drain
pan
DO NOT OPEN THE DRAIN VALVE WHILE
FRYPOT IS UNDER PRESSURE. HOT SHORTENING WILL EXHAUST FROM THIS VALVE, AND
SEVERE BURNS WILL RESULT.
Drain Interlock Switch A microswitch that provides protection for the frypot in the event an
operator inadvertently drains the shortening from the frypot while
the main switch is in the COOK position; the switch is designed to
automatically shut off the heat when the drain valve is opened
Condensation Drain Pan A collection point for the condensation formed within the steam
exhaust system; it must be removed and emptied periodically,
usually daily
Shortening Mixing System Ensures the shortening is properly mixed to prevent an accumulation
of moisture, causing boiling action in the frypot; the filter pump is
activated by the controls, at preset intervals, to mix the shortening
Lid Latch A mechanical catch on the front of the lid which engages a bracket
on the front of the pot; this device holds the lid down while the lid is
being locked into place, but is not meant to hold pressure in the
frypot
3-2 803
3-1. OPERATING CONTROLS
(Continued)
High Limit This is a safety component that senses the temperature of the
shortening, and if the temperature of the shortening exceeds
420°F (216°C), this control opens and shuts off the heat to the
frypot; when the temperature of the shortening drops to a safe
operation limit, the control must be manually reset by pressing
the red reset button, located under the control panel, in the
front of the fryer
Ignition Modules Sends 24 volts to the gas control valve and high voltage to the
ignitors
Model 691
Spark Ignitors When the pilots are being lit, the spark ignitors are electrically
energized and the tip of the ignitors spark to ignite the pilot lights
Flame Sensors Senses the pilot lights when the power switch is turned on; if the
pilots go out, or do not light, the flame sensors shut the gas off, via
the modules
Gas Control Valve A dual controller, in which one side of the valve controls the pilot
light on the right side, and the other side controls the pilot light on
the left side; if one pilot goes out, the other pilot goes out also
Airflow Switch
To avoid property damage, do not tamper with or disassemble this component. It is set and sealed from the
factory and is not to be adjusted.
Senses the flow of air coming from the blower; if the airflow is
reduced below a set amount, the switch will cut power to the
control valve, which shuts down the burners
Blower Adds the proper amount of air into the burner tubes, so an efficient
combustion takes place, and pulls the flue gases out to the flue
Air Valve Pumps air into the shortening, periodically, to keep the shortening at
a uniform temperature; this only functions when the unit has been
sitting idle for a period of time, and when heating up from a cold
start

3-5. FILLING OR ADDING
SHORTENING
Model 691
The shortening level must always be above the burner
tubes when the fryer is heating and at the frypot level
indicators on the rear of the frypot (See photo below).
Failure to follow these instructions could r esult in a fir e
and/or damage to the fryer.
When using solid shortening, it is recommended to melt
the shortening on an outside heating source befor e placing it in the frypots. The burner tubes must be
completely submerged in shortening. Fire or damage to
the frypot could result.
1. It is recommended that a high quality shortening be used in the
fryer. Some low grade shortenings have a high moisture
content and will cause 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 gas model requires 130 lbs. (59 kg) of shortening. The
frypot has 4 level indicator lines inscribed on the rear wall
of thefrypot which show when the heated shortening is at the
proper level. See photo at left.
3. Cold shortening should be filled to the lower indicators.
BE CERT AIN THE SHOR TENING IS NEVER
ABOVE THE UPPER LEVEL INDICA TOR LINES.
FAILURE TO FOLLOW THESE INSTRUCTIONS
CAN RESUL T IN SHORTENING OVERFLOWING
THE FRYPOT CAUSING SERIOUS BURNS, PERSONAL INJUR Y , FIRE AND/OR PROPERTY
DAMAGE.

3-6. PRODUCT RACKING
RECOMMENDATIONS The rack positions are referenced starting at the bottom:
4 _____________
3 _____________
2 _____________
1 _____________
The bottom position is to be avoided on small loads because it is
closer to the cold zone. (The oil is cooler at the bottom of the frypot
and hotter at the top.) With bigger loads, however, there is generally
enough turbulence in the oil that the bottom rack gets sufficient heat.
The top position is to be avoided on small loads because of
insufficient oil coverage. With bigger loads, the top rack has good
oil coverage because the volume of product on the lower racks
raises the overall oil level.

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
from a cold, or shutdown condition, back into operation. These
are basic, general instructions.
1. Make sure the shortening is filled to the proper level in
the frypot; to the two lower level indicators.
DO NOT OVERLOAD, OR PLACE PRODUCT WITH
EXTREME MOISTURE CONTENT INTO THE
RACKS. 32 LBS. (14.5 KG) IS THE MAXIMUM
AMOUNT OF PRODUCT PER FRYPOT . FAILURE
TO FOLLOW THESE INSTRUCTIONS CAN RE
SUL T IN SHOR TENING OVERFLOWING THE
FRYPOT WHICH COULD CAUSE SERIOUS
BURNS, PERSONAL INJUR Y , FIRE AND/OR
PROPERTY DAMAGE.
2. Turn the COOK/PUMP switch to the COOK position and
press the appropriate product button to select product to be
cooked. Unit automatically goes into the Melt Cycle.
When temperature reaches 230° F (110° C) the control
goes into the Heat Cycle, and heats the shortening to the
setpoint temperature.
3. Stir the shortening as it is heating up from a cold start.
Be sure to stir down into the cold zone.
DO NOT STIR THE SHOR TENING AT ANY OTHER
TIME EXCEPT A T MORNING ST ART-UP . FAILURE TO FOLLOW THESE INSTRUCTIONS CAN
RESUL T IN SHOR TENING OVERFLOWING THE
FRYPOT WHICH COULD CAUSE SERIOUS
BURNS, PERSONAL INJUR Y , FIRE, AND/OR
PROPERTY DAMAGE.

3-7. BASIC OPERATION 4. Allow fryer to heat until illuminates.
(Continued)
Bypass 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.
Do not bypass the Melt Cycle unless enough shortening
has melted to completely cover all of the burner tubes.
If the Melt Cycle is bypassed before all burner tubes
are covered, excessive smoking of shortening or a fire
will result.
Model 691
The heat cycles on and off about
10°F (6°C) before the
setpoint temperature, to help prevent overshooting the
setpoint temperature. (Proportional Control)
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.
5. Slide racks of breaded product into carrier on the lid,
starting with the bottom tier, to avoid damaged product.
Before loading product onto the racks, lower the racks
into the hot shortening to prevent the product sticking to
the racks.
6. Lower and lock the lid, and press .
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 .
7. At the end of the cycle, the pressure vents automatically and
an alarm sounds, while the display shows “DONE”. Then,
press .

3-7. BASIC OPERA TION 8. W ait for the pressure gauge to show zero (0) pressure in the
(Continued) pot before attempting to open the lid.
DO NOT LIFT HANDLE OR FORCE LID LA TCH
OPEN BEFORE PRESSURE GAUGE READS “0”
PSI. ESCAPING STEAM AND SHOR TENING WILL
RESULT IN SEVERE BURNS.
9. Unlock and raise the lid cautiously .
10. Using the rack handles, remove the racks of product from
the carrier , starting with the top rack, to avoid damaged
product.
11. 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.
12. At the end of the Hold Cycle, a tone sounds, the display
flashes “QUALITY”, and the product it was timing. Press
and release .
In a Cook Cycle, when “FIL TER 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.
When “FILTER LOCKOUT” , then “YOU *MUST*
FIL TER NOW........” shows in the display , is the only
button that functions, until the unit is filtered. Follow the filtering
instructions in this manual.
3-14 1104
Model 691
3-7. BASIC OPERATION Once filtering is complete and the COOK/PUMP switch is
(Continued) turned back on, “IS POT FILLED” shows in the display,
followed by “1=YES 2=NO”.
If shortening is at the proper level in the frypot, press and
the controls start a normal heating process.
If shortening is NOT at the proper level, press and
“TURN OFF UNTIL FILLED…” scrolls through the display.
Turn the COOK/PUMP switch to the OFF position, fill frypot to
the proper level, then turn the COOK/PUMP switch back to the
COOK position.
Again, “IS POT FILLED” shows in the display, followed by
“1=YES 2=NO”. This time press and unit resumes
normal heating process.
When the fryer is heating, the shortening level must always
be above the heating elements. Failure to follow these
instructions could result in a fire and/or damage to the fryer.
