TROUBLE LIGHT — Indicates fryer has been shut down by second high limit

thermostat.

ADDING SHORTENING

If replacing shortening, place the block of shortening in the room with the fryer for 1 to 2 hours before
using. This will soften the shortening and make it easier to divide.

CAUTION: Failure to remove crumb screens prior to addition of fresh shortening may cause
fryer side walls to overheat, allowing shortening to reach flashpoint.

After draining shortening, allow the tank to cool down before adding all new shortening to avoid
scorching new shortening.

Shortening Capacity

Full Vat 50 lb.
Split Vat 25 lb. each vat

— 5 —

Split Vat

1. Remove crumb screens.

2. Divide a 50-pound block of shortening into two equal halves (approximately 25 pounds each).

3. Place each half of the shortening directly on the heating elements in each well of the fry tank and
slide back.

4. Place crumb screens on top of shortening in tank.

Single Vat

1. Remove crumb screen.

2. Place 50-pound block of shortening directly on the heating elements in the tank and slide back.

3. Place crumb screen on top of shortening.

Melt Cycle

1. Set temperature control knob to desired cooking temperature and turn on power switch. Place Fry/
Melt switch in the MELT position. It will take approximately 45 minutes to completely melt the cold
shortening. Energy savings may be obtained by covering the vat(s) during the melt cycle.

2. Elements will cycle on and off until the shortening melts and a temperature of 135°F is obtained.
Then the temperature controller will bring the fryer to set temperature.

HIGH LIMIT CONTROL

The function of the high limit control is to shut the fryer down in the event of a thermostat failure which
would allow the shortening to be overheated. The operating temperature of the high limit control is
435°F, or 60°F higher than the highest temperature allowed by the thermostat when the thermostat
is functioning properly.

In the event of a High Limit "Shutdown," the entire control system will be put out of operation.

DO NOT attempt to restart the fryer until the temperature of the shortening has lowered to
approximately 350°F.

If this situation persists, do not attempt to bypass the High Limit; shut fryer down and contact a Vulcan­authorized service agency.

DRAINING AND FILTERING SHORTENING

Turn power switch OFF when draining or filling.

— 6 —

1. Allow shortening to cool before draining or filling.

2. Consult the operating instructions supplied by the manufacturer of your filtering system before
filtering the shortening.

3. Firmly screw the fryer drain nipple (supplied) into the fryer drain valve (Fig. 2). Position your filtering
container under the drain nipple mouth before opening the drain valve.

4. Completely open the drain valve. Let the shortening drain into the filter container. If the drain valve
becomes clogged with food particles, use the cleaning rod supplied with your fryer to unclog the
valve.

Use the cleaning rod with care from inside the fryer vat. Do not hammer on the drain valve with the
cleaning rod from inside or outside the fry vat. This type of abuse will damage the drain valve.

5. If it is necessary to clean the fry tank more thoroughly, follow the procedure shown in CLEANING
— WEEKLY OR AS REQUIRED.

6. Close drain valve and pour filtered shortening back into fry tank to continue frying.

SHORTENING MAINTENANCE

Shortening life may be extended by following these important procedures.

Do not salt foods over the fryer.

Use good quality shortening.

Filter shortening daily at a minimum.

Keep equipment and surroundings clean.

Set thermostats correctly. Do not use excessively high temperatures.

Remove excess moisture and particles from food products before placing in fryer.

Dip out several cups of shortening from fry tank every day and add fresh shortening to replace it.

CLEANING

DAILY

Clean your fryer regularly. 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. Do not use standard steel wool
on stainless steel finishes. Pieces of the steel wool will adhere to the stainless steel and cause rusting.
Always rub in the direction of the polish lines on the steel front to preserve the original finish.

Keeping the fryer exterior clean and free of accumulated grease will prevent stubborn stains from
forming. 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.

WEEKLY OR AS REQUIRED

Heating Elements and Thermostat Bulb

1. The fry tank must be at operating temperature.

2. Turn power switch OFF.

3.Wear protective gloves, and using the lift rod, raise elements out of hot shortening. Allow
shortening to drip off for five minutes.

4. Place cover(s) (optional extra) over fry tank(s) to preserve clean shortening.

5. Turn operating thermostat to 300°F.

6. Turn power switch ON. DO NOT leave fryer unattended. The second high limit will trip out,
terminating the burn-off cycle.

— 8 —

7. Turn power switch OFF at termination of burn-off cycle.

8. Heating elements will heat up in excess of 600°F glowing red. If any do not glow, call a Vulcan­authorized service agency. Some smoking, crackling sound and puffs of flame will occur. This is
normal. If excessive flaming occurs, turn power switch OFF and extinguish immediately to prevent
damage to elements and thermostat bulbs.

9. Allow elements to cool and press reset button on rear of element head (Fig. 3).

10. Brush residue from elements and thermostat bulbs with a nylon brush. Take care not to bend or
displace temperature controller bulbs.

11. Remove cover(s) (optional extra) from fry tank(s) and lower elements into shortening.

12. Proceed with filtering procedures.

Fry Tank

1. Drain and strain shortening into a clean container and refrigerate if necessary.

2. Close drain valve (see Fig. 2) and fill tank to the full line with hot water and all purpose cleaning
concentrate.

3. Set temperature control knob to 212°F and turn power switch ON. DO NOT leave fryer unattended.

4. Boil the cleaning solution for 30 minutes. Readjust temperature control to maintain a soft boil.

5. Turn power switch OFF. Add two gallons of cold water (for single vat) or one gallon (for each split
vat) to cool the solution.

— 9 —

6. Drain solution and discard. Close drain valve and fill tank half full with water.

7. Scrub entire inside of tank with a stiff bristle nylon brush.

8. Drain solution and rinse tank thoroughly with clean water.

9. Close drain valve and refill tank with clean hot (minimum 140°F) water. Add 1 cup of vinegar to
neutralize alkaline left by the cleaner. Turn power switch ON and boil again for 15 minutes.

10. Turn power switch OFF, allow solution to cool, drain, then rinse thoroughly with clear, hot water until
clean. Wipe dry with a clean cloth.

11. Close the drain valve. Add shortening.

STAINLESS STEEL

Stainless steel may be cleaned with ordinary soap or detergent and water. To prevent water spots and
streaks, rinse equipment thoroughly with warm water and wipe dry with a soft clean cloth. The addition
of a rinsing agent will also help prevent spotting.

Fingerprints

Fingerprints are sometimes a problem on highly polished surfaces of stainless steel. They can be
minimized by applying a cleaner that will leave a thin, oily or waxy film. Wipe cleaner on and remove
excess with a soft dry cloth. After using, subsequent fingerprints will usually disappear when wiped
lightly with a soft dry cloth, or with a cloth containing a little of the cleaner. If the surface is especially
soiled to start with, wash first with soap or detergent and water.

Burned On Foods and Grease

Soaking with hot soapy water will help greatly to remove burned on foods and grease. Stubborn
deposits can be removed with scouring powder mixed into a paste and applied with stainless steel wool
or sponges. Always rub with the "grain" in a horizontal direction.

Heat Tint

Straw-colored or slightly darkened areas may appear on stainless steel equipment where temperatures
reach 500°F or more. This "Heat Tint" is caused by a slight oxidation of the stainless steel and is not
harmful. To control this condition, never use more heat than is absolutely necessary.

Precautions

When scraping off heavy deposits of grease or oil from stainless steel equipment, never use ordinary
steel scrapers or knives. Particles of ordinary steel may become embedded in, or lodge on, the surface
of the stainless steel. These will rust, causing unsightly stains. Where it is necessary to scrape, use
stainless steel, wood, plastic or rubber tools, or stainless steel wool.

MAINTENANCE.

CALIBRATION PROCEDURES

1. Monitor shortening temperature 1" below the surface with an accurate temperature measuring
device.

2. Turn power switch ON, and when coming up from lower temperature, set temperature control knob
to frying temperature.

3. Allow fryer to reach temperature (when heating light goes out) and maintain it (by cycling) for 15
minutes.

4. Check temperature when the heating light first comes on. If the reading is not within five degrees
of the temperature control setting, take the following steps.

A. Loosen the set screw in the temperature control knob.

B. Rotate the knob and set the knob to read the same as the shortening temperature readings.

C. Tighten the set screw.

D. Allow the fryer to cycle and check the readings.
