SECTION 1. INTRODUCTION

1-1. PRESSURE FRYER The Henny Penny Pressure Fryer is a basic unit of food pro-

cessing equipment. It has found wide application in institutional and commercial food service operations.

P-H-T A combination of Pressure, Heat, and Time is automatically

controlled to produce the optimum in a tasty , appealing product.

Pressure Pressure is basic to this method of food preparation. The pres-

sure is developed from the natural moisture of the food. The patented lid traps this moisture and uses it as steam. Because the steam builds rapidly , the greater part of the natural juices are retained within the food. An operation valve vents excess steam from the pot and maintains constant live steam pressure.

Heat Heat generated is another important factor of the pressure fryer .

Energy savings is realized due to the unit’ s short frying time, low temperature, and heat retention of the stainless steel cookpot.

Time Time is important because the shorter time involved in frying

foods results in additional economies for the user . Foods are table ready in less time than it would take to fry them in a conventional open-type fryer .

1-2. PROPER CARE As in any unit of food service equipment, the Henny Penny

Pressure fryer does require care and maintenance. Requirements for the maintenance and cleaning are contained in this manual and must become a regular part of the operation of the unit at all times.

1-3. ASSIST ANCE Should you require outside assistance, just call 1-800-417-

2-2. SELECTING THE FRYER The proper location of the fryer is very important for opera LOCATION tion, speed, and convenience. Choose a location which will

provide 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 warmer 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 effi ciency will be obtained by a straight line operation, i.e. raw in one side and finish 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 unit is needed for proper air supply to the combustion chamber .

The gas Fryer is designed for installation on combustible floors and adjacent to combustible walls. Fryer must be installed with minimum clearance from all combustible and noncombustible materials, 6 inches (15.24 cm) from side and 6 inches from back.

NOTE

The fryer should be installed in such a way as to prevent tipping or movement causing splashing of hot shortening. This may be accomplished by the location of the fryer, or by restraining ties.

The area under the 691 cooker is not to be used as storage. The filter pan sets under the cooker , and stored supplies under the unit would be ruined and could be a fire hazard.

2-3. LEVELING THE FR YER For proper operation, the fryer must be level from side to

side and front to back. Using a level placed on the flat areas around the frypot collar, adjust the leveling bolt or casters until the unit is level.

Failure to follow these leveling instructions can result in shortening overflowing the cookpot which could cause serious burns, personal injury , fire and/or property damage.

2-4

Henny Penny Model 691

2-4. VENTILATION OF FRYER The fryer should 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. Special precaution must be taken in designing an exhaust canopy to avoid interference with the operation of the fryer . Make certain the exhaust hood is designed high enough to allow for proper opening of the fryer lid. W e recommend you consult a local ventilation or heating company to help in designing an adequate system.

NOTE

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

2-5. GAS SUPPL Y The gas fryer is factory available for either natural or propane

gas. Check the data plate on the right side panel of the cabinet to determine the proper gas supply requirements. The minimum supply for natural gas is 7 inches water column and 10 for propane.

Do not attempt to use any gas other than that speci fied on the data plate. Incorrect gas supply could result

in a fire or explosion resulting in severe injuries and/or property damage.

2-6. GAS PIPING 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 Na-

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

• The fryer and its individual shutoff 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 kPa) (34.5 mbar).

2-5

Henny Penny Model 691

2-6. GAS PIPING • The fryer must be isolated from the gas supply piping (Continued) system by closing its individual manual shutoff 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) (34.5 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).

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 (minimum 3/4”) A.G .A. certified connector which complies with standard connectors for moveable gas appliances. ANSI Z21.69 (the latest edition) or CAN l, 6. l0M88. Also, a quick disconnect coupling which complies with the Standard for Quick Disconnect Devices for use with Gas Fuel, ANSI Z21.41 (the latest edition) or CAN 1 6.9M79. Also, adequate means must be provided to limit the movement of the fryer without depending on the connector and any quick-disconnect device or it’ s 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.

NOTE

The cable restraint limits the distance the cooker can be pulled from the wall. For cleaning and servicing the cooker, the cable must be unsnapped from the unit and the flexible gas line disconnected. This will allow better access to all sides of the cooker . The gas line and cable restraint

must be reconnected once the cleaning or

servicing is complete.

2-6

Henny Penny Model 691

2-7

Henny Penny Model 691

2-7. GAS PRESSURE The gas pressure regulator on the automatic gas valve is REGULA TOR SETTING factory set as follows:

Natural: 3.5 inches water column (8.7 mbar) Propane: 10.0 inches water column (24.9 mbar)

Be certain gas pressure is set correctly . Failure to do so can result in shortening overflowing the cookpot, which could cause serious burns, personal injury , fire and/or property damage.

2-8. ELECTRICAL The gas fryer requires 120 or 240 volt, single phase, 50/60 REQUIREMENTS (GAS Hertz, 10 or 5 amp, 2 wire + ground service. The gas fryer is FRYER) factory equipped with a grounded cord and plug for your

protection against shock, and should be plugged into a 3 prong grounded receptacle. Do not cut or remove grounding prong. A wiring diagram is located behind the right side panel, and can be accessed by removing the side panel.

DO NOT DISCONNECT THE GROUND PLUG. This fryer MUST be adequately and safely grounded or electrical shock could result. Refer to local electrical codes for correct grounding procedures or in absence of local codes, with The National Electrical Code, ANSI/NFP A No. 70-(the current edition). In Canada, all electrical connections are to be made in accordance with CSA C22.1, Canadian Electrical Code Part 1, and/or local codes.

The main power switch on this appliance does not disconnect all line conductors. This appliance must be equipped with an external circuit breaker which will disconnect all ungrounded conductors.

2-9. TESTING THE FRYER Each Henny Penny pressure fryer was completely checked

and tested prior to shipment. However, it is good practice to check the unit again after installation.

2-8

Henny Penny Model 691

2-10. GAS LEAK TEST NOTE

Prior to turning the gas supply on, be sure the gas dial cock on the fryer gas 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 and occur, it indicates escaping gas. In this event, the piping connection must be redone.

Never use a lighted match or open flame to test for gas leaks. Escaping gas could cause an explosion resulting in severe personal injury and/or property damage.

SECTION 3. OPERA TION

3-1. OPERA TING CONTROLS

Power/Pump Switch The Power/Pump Switch is a three way switch with center

“OFF” position. Move the switch to the position marked “POWER” to operate the fryer . Move the switch to the position marked “PUMP” 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.

Cookpot 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.

Cooking Carrier This stainless steel carrier consists of five racks which contain

the food product during and after frying.

Lid Gasket The lid gasket provides the pressure seal for the cookpot

chamber .

Operating Valve The dead weight style operating pressure relief valve is used to

maintain a constant level of steam pressure within the cookpot. Any excess steam pressure is vented through the exhaust stack.

NOTE

The dead weight cap should be removed, and the cap, weight, and orifice, be cleaned once a day to prevent over pressurization inside the cookpot

Safety Relief Valve The safety relief valve is an ASME approved spring loaded valve

set at 14.5 psi (999 mbar). In the event the operation valve be comes obstructed, this safety valve will release excess pressure, keeping thecookpot chamber at 14.5 psi (999 mbar). If this occurs, turn the Power/Pump switch to the “OFF” position to release all pressure from the cookpot.

Safety Relief Valve Lever THE LEVER IS NOT TO BE PULLED.

Severe burns from the steam will result.

3-1

Henny Penny Model 691

3-1. OPERA TING CONTROLS

(Continued)

Pressure Gauge The pressure gauge indicates the pressure inside the cookpot.

Solenoid V alve The solenoid valve is an electromechanical device that cause

pressure to be held in the cookpot.

The solenoid valve closes at the beginning of the frying cycle and is opened automatically at the end of the frying cycle. If this valve should become dirty or the teflon seat nicked, pressure will not build up and it must be repaired per the maintenance section.

Drain V alve The drain valve is a two-way ball valve. It is normally in the

closed position. Turn the handle to drain the shortening from the cookpot into the filter drain pan.

DO NOT OPEN THE DRAIN V AL VE WHILE COOKPOT IS UNDER PRESSURE. Hot shortening will exhaust from this valve. Severe burns will result.

Drain Interlock Switch The drain interlock switch is a microswitch that provides

protection for the cookpot in the event an operator inadvertently drains the shortening from the cookpot while the main switch is in the POWER position. The switch is designed to automatically shut off the heat when the drain valve is opened.

Condensation Drain Pan The condensation drain pan is the collection point for the

condensation formed within the steam exhaust system. It must be removed and emptied periodically .

Shortening Mixing System The unit is equipped with a shortening mixing capability so as

to ensure shortening is properly mixed to prevent an accumulation of moisture and hence boiling action in the pot. The filter pump is activated by the controls, at predetermined intervals, to mix the shortening.

3-2

Henny Penny Model 691

3-1. OPERA TING CONTROLS

(Continued)

Lid Latch The cooker lid is equipped with 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.

High Limit This high temperature control senses the temperature of the

shortening, and if the temperature of the shortening exceeds 420°F (212°C), this control will open and shut off the heat to the cookpot. When the temperature of the shortening drops to a safe operation limit, the control must be manually reset.

Ignition Modules The two ignition modules send 24 volts to the gas valve and

high voltage to the ignitors.

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 The flame sensors sense the pilot lights when the power switch

is turned on. If the pilots go out, or do not light, the flame sensors will shut the gas off, via the modules.

Gas Control V alve The gas valve is 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 The airflow switch 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 the burners down.

Blower The blower adds the proper amount of air into the burner tubes,

so an efficient combustion takes place, and also, pulls the flue gases out to the flue.

Air V alve The air valve allows air into the filter lines whenever the pump

motor is on, in the mixing mode, therefore allowing air or shortening to be pumped even with clogged filter screens.

3-3

Henny Penny Model 691

3-2. LID OPERATION

T o close lid:

1. Lower the lid until gasket comes into contact with the pot.

2. W ith the lid lowered, pull lid handle forward until it stops.

3. Lift up on the lid handle until it stops.

4. Bring lid handle out towards you until it stops.

5. Push lid handle down, locking lid in place.

DO NOT A TTEMPT TO OPEN LID UNTIL THE PRESSURE DROPS TO ZERO. Opening the lid when the cookpot is pressurized will allow hot shortening and moisture to escape from the cookpot, resulting in severe burns.

T o open lid:

1. Unlatch the front lid latch.

2. Gently raise handle until it stops.

3. Push handle back until it stops.

4. Lower handle.

5. Push handle back and raise lid

3-4. FILLING OR ADDING

SHORTENING 1. It is recommended that a high quality frying shortening

be used in the pressure cooker . Some low grade shortenings have a high moisture content and will cause foaming and boiling over.

2. If a solid shortening is used, it can be melted into a liquid first, then poured into the cookpot. Attempting to melt solid shortening in the cookpot may cause burning or scorching of the fresh shortening.

3. The gas model requires 130 lbs. (59 kg.) The cookpot has three level indicator lines inscribed on the rear wall of the cookpot which show when the heated shortening is at the proper level.

4. Cold shortening should be filled to the two lower indicators.

DO NOT fill cookpot with shortening above the upper cookpot “Fill” line. This could cause the shortening to overflow the cookpot, which could cause serious burns, personal injury , fire and/or property damage.

The shortening level must always be above the heat exchanger coils when the cooker is heating. Failure to follow these instructions could result in a fire and/or damage to the cooker.

3-5. BASIC OPERATION The following procedures should be followed on the initial

start-up of the cooker, and each time the cooker is brought from a cold, or shut down condition, back into operation. These are basic, general instructions.

1. Make sure the shortening is filled to the proper level in the cookpot; ½ inch (1.25cm) below lower indicators.

Be certain the shortening is never above the upper cookpot “fill” line. Failure to follow these instructions can result in shortening overflowing the cookpot which could cause serious burns, personal injury , fire and/or property damage.

2. T urn the Power/Pump switch to the power position and press the appropriate product button to select the amount of product to be cooked.

NOTE

The controls have a 45 second delay from when the power switch is turned on, to when the burners ignite.

3. Stir the shortening as it’ s heating up from a “cold” start. Be sure to stir down into the “cold zone”.

DO NOT stir the shortening at any other time except at “cold” start-up. Failure to follow these instructions can result in shortening overflowing the cookpot which could cause serious burns, personal injury , fire and/or property damage.

4. Allow cooker to heat until digital display shows “READY”.

3-5. BASIC OPERATION NOTE

(Continued) The controls have proportional control capabilities, which

means the heat will cycle on and off approximately 10 degrees before the setpoint temperature, to help prevent overshooting the setpoint temperature.

5. Slide racks of breaded product into carrier on the lid, starting with the bottom tier .

NOTE

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 down and press the appropriate product button.

7. At the end of the cycle, pressure will begin venting automatically , and alarm will sound, and the display will show “DONE”. At this time, press the appropriate Product button.

8. W ait for the pressure gauge to show “0” pressure in the pot before attempting to open the lid.

Check the pressure gauge reading. DO NOT attempt to open the lid until the pressure drops to zero. Opening the lid when the cookpot is pressurized will allow hot short ening and moisture to escape from the cookpot, resulting in severe burns.

9. Unlock and raise the lid quickly .

10. Using the rack handles, remove the racks of product from the carrier, starting with the top rack.

3-5. BASIC OPERATION NOTE

(Continued) In the event of a power failure, no attempt should be

made to operate the fryer. The model 691 cooker is equipped with an automatic ignition system and cannot be operated without electrical power .

3-6. CARE OF THE SHORTENING 1. T o protect the shortening when the fryer is not in imme-

diate use, the fryer should be put into the “IDLE” mode.

2. Frying breaded products requires filtering to keep the shortening clean. The shortening should be filtered at least twice a day; after lunch rush and at the end of the day .

3. Maintain the shortening at the proper cooking level. Add fresh shortening as needed.

Failure to follow these instructions can result in shortening overflowing the cookpot which could cause serious burns, personal injury , fire and/or property damage.

3-7. FIL TERING The Henny Penny Gas 8 Head Fryer, model 691, must be INSTRUCTIONS cleaned and the shortening must be filtered at least twice daily;

after lunch rush and at the end of the day .

Shortening should be filtered immediately following a cook cycle when the shortening temperature is less than 270° F . DO NOT DRAIN THE SHORTENING IF IT IS A T READY TEMPERA TURE. The high temperature can cause cracklings to burn on the steel cookpot surfaces after the shortening has drained.

3-7. FIL TERING INSTRUCTIONS (continued)

Filter only when the shortening temperature is less than 270° F (132° C). Failure to do so can result in shortening overflowing the cookpot, causing serious burns, personal injury , and/or property damage.

If volume dictates, cleaning may be required more often. Part of the process involves removing cracklings from the cold zone of the cookpot. High volume cooking could cause the cold zone to fill quicker with cracklings, and if so, cleaning would be required. SURF ACES OF FR YER AND COOK BASKET WILL BE EXTREMEL Y HOT . USE CARE NOT TO GET BURNED.

1. Turn power/pump switch OFF before draining shortening.

2. Make sure drain pan is under cooker and the dairy union is tightened to the standpipe, coming out of the pan.

The filter 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 will cause splashing of shortening and could result in severe burns.

3. Remove cooking racks and wipe bottom of lid. Tilt lid out of the way to clean cookpot.

4. Pull drain handle towards you to open drain valve. The handle should point straight out to the front of the cooker. Use L-shaped brush to clean cracklings from the heat tubes and from sides and bottom of cookpot as shortening drains. Use straight brush to push cracklings through drain opening in bottom of cookpot if necessary, and to clean between the heat exchanger coils and the pot wall.
