OPTIONAL VENTLESS EXHAUST HOOD

The ventless exhaust hood is a self-contained air filtration system and includes a fire suppression system manufactured by ANSUL

Fire Protection, 1 Stanton Street, Marinette, Wisconsin 54143. It enables operation of the pressure fryer in a location without an externally-exhausted ventilation hood and wall-mounted fire suppression system. The three-stage filtration system removes oil particles,

steam and condensation, and cooking odors from the exhaust air. The ANSUL

Fire Suppression System actuates automatically if the temperature below the hood exceeds 165°F (74°C), or it can be manually triggered by the operator. In either case, fryer operation will be disabled. A damper at the blower outlet will close automatically to restrict air flow to the fire.

The ANSUL® Fire Suppression System must be charged and certified by an authorized ANSUL® dealer.

Hobart Corporation is not permitted to service the fire suppression system; only an ANSUL

properly maintain the fire suppression system. The ANSUL

representative must also adjust the nozzle

dealer may

of the system at the time of charging.

The ANSUL

A separate instruction manual is provided that details the ANSUL

system must be fully charged and operational for your appliance to be operational.

Fire Suppression System.

Safety interlocks disable operation of the fryer if (a) the fire suppression system is not charged and cocked; (b) one or more filters are missing or incorrectly installed; or (c) the exhaust blowers are not operating. Indicator lights aid troubleshooting by pinpointing open interlock switches.

Installation

The ventless exhaust hood is shipped separately from the pressure fryer. Assembly of the ventless exhaust hood to the pressure fryer will require a minimum of two people. It is recommended that you install and connect the hood assembly prior to powering the fryer.

To prepare the pressure fryer:

1. Make sure the front casters on the pressure fryer are locked before installing the hood.

FILLING THE KETTLE WITH LIQUID SHORTENING

Oil Capacity: 26 pounds (12 kg).

Use only a pure, vegetable, hydrogenated oil prescribed for use in pressure fryers, such as Mel Fry, Crystal, FryMax, or Gold Label. Never add suet.

Close drain valve (Fig. 21). Fill kettle with liquid shortening; solid shortening is not recommended.

• If shortening is hot, fill kettle to the MAXIMUM line on the crumb catcher probe cover (Fig. 22).

• If shortening is room temperature, fill kettle to the MINIMUM line. This level allows for oil expansion when heated. Do not overfill.

Regularly add enough oil to keep the oil level in the kettle to the MAXIMUM line.

When changing to new oil, keep the level at the MINIMUM line.

DO NOT operate the fryer with no oil in the kettle.

USING THE PRESSURE FRYER

CAUTION: Before turning the fryer on, the kettle must be filled to the correct level with liquid shortening. If this is not done, the kettle walls can be damaged. Warpage can cause leaks.

Pressure is created by the containment of moisture escaping from the product being fried. Dry products that produce little or no moisture will not create sufficient pressure to pressure-fry that product. Pressure will not build without product in the kettle.

1. Place the power switch in the ON position. If the fryer is equipped with the optional ventless exhaust hood, all three hood filters must be in place.

2. After the fryer is turned on, the display will show prE-HEAt, alternating with the rising oil temperature in degrees Fahrenheit.

– 16 –

3. When the oil temperature reaches 325°F (163°C) or the programmed temperature, the screen will display rEAdy and an audible tone will sound for 2 seconds. The screen will then display idLE until a program (frying cycle) is initiated. After the screen reads idLE, place the frying basket into the oil and proceed with cooking.

4. Using tongs or other long-handled utensil, place prepared foods evenly around the basket, one piece at a time. Load food in a circular motion so the basket is loaded uniformly and evenly.

5. After loading ten to twelve pieces of food, use insulated mitts and lift the basket high enough to clear the bottom of the kettle. Swirl the basket a couple of times in the oil to keep pieces from sticking together.

6. Lift the basket out of the oil and hang the basket on the lip of the kettle. Continue loading the food (maximum capacity is 15 pounds (7 kg) of food). When the desired amount of food is placed in the basket, give the basket one more swirl in the oil. Close the lid. Make sure the lock post is fastened in the overarm post catch (Fig. 23). Hold the front post in place while tightening the handle.

WARNING: IF THE LID WILL NOT LOCK, DO NOT OPERATE THE FRYER.

OVERARM POST CATCH

7. After tightening the lid, press the desired program key (1 to 6). The light above the selected program key will light. The display screen will show the preprogrammed cooking time, then count down to 00:00, and cooking will begin. Once a program is started, there is a 5-second delay before there is any response to further program key presses.

8. If you wish to cancel the cooking cycle before the end of the preset time, press the selected program key again and hold for 2 seconds. Cooking will stop and the display will show rEAdy.

9. If you press the wrong program key, you can change it, but you must do it within 30 seconds. To change your selection, press the

wrong program key again and hold it in until the indicator light

on the key extinguishes. The fryer will stop cooking. Then press the correct program key.

– 17 –

10. The heat light and the heating elements will continue to cycle on and off and product will continue to cook until the audible tone sounds at the end of the cooking cycle. Pressure will automatically begin to release 45 to 60 seconds prior to the audible tone sounding. The selected program key will flash.

11. At the end of the frying cycle, the audible tone will sound and continue sounding until turned off manually. Press the flashing program key to silence the audible tone.

12. When the pressure gauge reads 0 and the lid lock releases, turn the handle counterclockwise

until it stops before opening the lid. CAUTION: Seal damage can occur if the handle is not completely unscrewed. Do not force the lid to open.

When loading and unloading product, always swing the lid to the side. Do not raise the lid.

13. Using insulated mitts, grasp the basket handle and raise the frying basket out of the oil. Hang the basket on the lip of the kettle. Allow food to drain approximately 20 to 25 seconds. Remove the food and return the basket to the oil. It is not necessary to turn the fryer off for unloading. Allow the kettle to recover and maintain the oil temperature, and mimimize the time between loads.

14. It is advisable to inspect the first load. If preparing unusually large pieces, or if product is only partially thawed, it may be necessary to increase cooking time (not temperature) to compensate.

Turning the Fryer Off

When the display shows idLE, turn the power switch to OFF.

Extended Shutdown

1. When the display shows idLE, turn the power switch to OFF.

2. Clean the fryer following the instructions in the CLEANING section of this manual. The solenoid assembly must be cleaned thoroughly and routinely.

POWER FAILURE

In the event of a power failure, turn the power switch to OFF. After the pressure gauge indicates 0, open the kettle lid and remove the basket. If interrupted, the program will automatically cancel after 60 seconds of power loss.

Repeat all startup procedures upon resumption of electrical service. The controller resets to its wakeup mode, and can be restarted by turning the power switch to ON and allowing the fryer to cycle through its automatic preheat stage.

FOOD PREPARATION

Pressure frying seals in the natural moisture of food products and uses 30% less frying oil. It should be remembered, however, that no food prepared in the Hobart pressure fryer will be any better than the quality of the product purchased.

Trim excess skin and fat from product. Coat with your preferred breading. Allow the breading to set up (become sticky) before frying; this takes about 20 minutes. If breading is not allowed to set up, it may wash off in the hot oil.

– 18 –

Fresh chicken is frequently stored and sold in a hard-refrigerated state. Allow such product to thaw completely before preparing or frying. Comply with safe handling procedures regarding thawing. Hardrefrigerated chicken may be thawed overnight under refrigeration. Frozen chicken is defined as product sold as prebreaded chicken parts frozen to 0°F (-18°C) or below, and is intended for immediate frying without thawing or additional preparation. Use care when loading frozen chicken parts into the kettle, as ice crystals on the product may cause the hot cooking oil to spatter.

COOKING GUIDELINES

The cooking guidelines in the chart below are suggested only. They are based on average-sized portions. If unusually large pieces are not thoroughly cooked, increase cooking time, not temperature. Frozen portions will require a longer cooking time. Maximum capacity is 15 pounds (6.8 kg), or approximately 45 pieces of chicken. A typical load is considered to be 6 to 9 pounds (2.7 to 4 kg) of raw, breaded chicken.

HIGH-LIMIT

The pressure fryer is equipped with a high-temperature-limit switch that senses a higher than normal temperature. If a higher than normal temperature is sensed by the high-temperature-limit switch, the fryer will shut off and the pressure will be exhausted. Once the oil temperature cools to below the highlimit temperature, the high-limit thermostat will reset automatically. It is recommended that you turn the power off and swing the kettle lid open to allow the oil to cool. After the kettle has cooled to normal operating temperature, turn the power switch back on and resume the programmed cycle.

NOTE: The high-limit switch may activate during initial startup if the oil is hotter at the top of the kettle than at the bottom. Normal operation will return after the oil temperature has stabilized. If the high-limit switch activates anytime after initial startup, turn the pressure fryer off and call your local Hobart service office.

POP-OFF VALVE

The pop-off valve is located on the fryer lid. This valve is nonadjustable and preset at the factory to release the kettle pressure automatically if over 15 psig. The valve is also equipped with a ring (Fig. 24) that should be lifted if kettle pressure exceeds 15 psig and the valve does not release the pressure automatically. CAUTION: Do not allow kettle pressure to exceed 15 psig. Keep the exhaust port of the pop-off valve clear of obstructions.

WARNING: STEAM RELEASED BY THE POP-OFF VALVE MAY CAUSE BURNS. USE CAUTION WHEN OPENING THE VALVE.

Do not use the pop-off valve to manually relieve pressure as a regular practice. Allow pressure to release automatically.

DRAINING AND FILTERING OIL

WARNING: HOT OIL AND PARTS CAN CAUSE BURNS. USE CARE WHEN OPERATING,

CLEANING, OR SERVICING THE FRYER.

WARNING: DO NOT DRAIN OR FILTER OIL WHILE KETTLE IS UNDER PRESSURE.

To prolong oil life, it is recommended that you filter the oil after 85 to 90 pounds (39 to 41 kg) of product has been cooked. Filter the cooking oil using the Hobart HMF50 portable filter, or with a vacuum-style or gravity-style filter by others. Draining through cheesecloth will not clean the oil sufficiently for pressure frying.

Using the HMF50 Portable Filter: Follow the instructions shipped with the unit.

Filtering Oil and Cleaning Kettle at the End of the Production Day

This procedure must be performed daily while the kettle is still warm. Filtering time increases as the oil cools.

1. Turn fryer power switch to OFF before draining or filling. Open the lid.

2. If you use filter powder (diatomaceous earth), follow the manufacturer's instructions and add filter powder to the oil in the kettle. Stir with the wooden doughnut stick provided.

– 20 –

3. Position filtering system under the drain, open the drain valve, and drain oil until approximately 2" (5 cm) of oil remains in the kettle.

4. Using a long-handled brush, wash sides and bottom of kettle with the remaining warm oil, then finish draining tank.

5. While oil is out of the kettle, remove any excess breading from the crumb catcher (see Fig. 22). Use the wooden doughnut stick provided to dislodge any material that may have collected in the kettle drain.

6. CAREFULLY pour 2 to 3 gallons (7.6 to 11.3 L) of COLD water into the kettle. Use a nylon pad (nonabrasive, plastic web-type, nonrusting, nonshredding pad) to wash the kettle completely. Drain the water into a drainage receptacle. Rinse the kettle well with clear water. Drain again. Wipe the kettle dry with a soft, clean, lint-free cloth. Close the drain valve.

7. Return the oil to the kettle. Check the oil level.

8. If cooking is to resume following the filtering operation, turn the power switch to ON and allow the fryer to heat. When the oil reaches cooking temperature (display shows idLE), place the frying basket into the oil and begin cooking.

9. If cooking has concluded for the day, clean the fryer according to the CLEANING procedures below.

Daily Cleaning

1. Before returning oil to the kettle following the final filtering operation of the day, close the drain valve and pour 1 or 2 gallons (3.8 or 7.6 L) of cold water into the kettle. Use a web-type, nonshredding, nylon scrubbing pad and thoroughly wash down the interior of the kettle. Drain the wash water into a pail and discard. Towel dry the interior of the kettle.

2. Close the kettle drain valve and return the filtered oil to the kettle. Add fresh oil as required to maintain the correct oil level.

3. Clean stainless steel regularly with a damp cloth and polish with a soft, dry cloth. If regular cleaning is neglected, grease will be burned on and discolorations may form. These may be removed by washing with any detergent or soap and water. Particularly stubborn discolorations may be removed with a self-soaping scouring pad or a paste made of water and a mild scouring powder applied with a plastic open pad or sponge. CAUTION: Always rub with the grain in a

horizontal direction.

4. It is important to keep the fryer exterior clean and free of accumulated grease. Wash all exterior surfaces at least once daily. Use a cloth with warm water and a mild soap or detergent. Follow with a clear rinse, then dry.

5. Wash the frying basket in hot, soapy water. Rinse thoroughly and dry.

MAINTENANCE

WARNING: THE PRESSURE FRYER AND ITS PARTS ARE HOT. BE VERY CAREFUL WHEN

OPERATING, CLEANING OR SERVICING THE PRESSURE FRYER.

WARNING: DISCONNECT ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE DISCONNECT SWITCH TO INDICATE YOU ARE WORKING ON THE CIRCUIT BEFORE SERVICING THE PRESSURE FRYER.

O-RING SEAL REPLACEMENTS

Removal and replacement instructions for the lid O-Ring are described in WEEKLY CLEANING — KETTLE TILT LID (page 24).

The O-Ring seals on the kettle pressure-relief valve assembly (see Fig. 28) need to be replaced if oil is leaking from the kettle lid. If steam leaks around the kettle pressure-relief valve O-Rings and goes into the exhaust tank, pressure will not build in the kettle. Dip the new O-Rings in cooking oil for lubrication and insert them into the pressure-relief valve assembly.

The O-Ring seal on the clean-out port thumb screw (see Fig. 28) needs to be replaced if liquid is leaking around the screw.
