SERVICE

WARNING: Hot oil and parts can cause burns. Use care when servicing the fryer.

WARNING: Disconnect from power source before be-

ginning any service.

SERVICING:

Any mechanical product, no matter how well made, will eventually need service attention. The equipment will need less service if given normal care and frequent cleaning. Have your service man check your equipment regularly. Vulcan fryers are engineered for serviceability.

Any part can be easily and quickly removed if necessary for cleaning, service or replacement. All parts are accessible from front of unit.

FILTERING:

Always filter frying compound when cold zone area under tubes is hot and liquid. A cold fryer heated up won't drain.

Fat under tubes in cold zone remains hard. Use drain stock if necessary to stir up hard fat into top fat to melt it.

Open filter bag and slip it over end of drain valve nipple.

Tie in place with bow knot behind pin on drain valve nipple so it won't slide off. Place receptacle under bag and turn on drain valve. Crumbs will be caught in bag but fat or oil will strain freely through bag into receptacle.

When kettle is empty, use small pot with handle as ladle and dip hot oil from receptacle and pour vigorously around sides and bottom of kettle to wash out crumbs and particles adhering to kettle. Continue to dip and pour until all crumbs are washed down and into filter bag. Hold ladle or pot under filter bag and untie bow knot. Hot bag full of crumbs will be caught in ladle. Carry to sink and wash for next use. Crumbs and particles can be dumped out of bag by turning bag inside out. Close valve and pour fat back into kettle to continue frying.

Filtering takes less time than frying one load of potatoes and will pay dividends in fat savings and food quality.

ADJUSTMENT:

See Detail 1B

PILOT BURNER: Requires no air or orifice adjustment.

Adjust gas supply only be removing the adjustment cover cap and turning the adjustment screw with a small screwdriver clockwise to reduce, counterclockwise to increase.

Pilot burner flame should extend past wing tips approximately

1/2".

If pilot burner fails to light or goes out, turn all controls to

"OFF" and wait 5 minutes before repeating lighting procedure.

If, when equipment is in operation, change in flame adjustment occurs, it means a drop in pressure or supply. Your service man should recheck lines for size, bends, stoppage, meter capacity, etc.

DETAIL 1B

Pilot Burners: Standard production types can be quickly disconnected and removed for service and cleaning.

Clean burners in warm soapy water, be sure to dry thoroughly before remounting. See Detail 2.

114590-8

PROBLEMS AND CAUSES

PROBLEM

Fryer not working to normal high speed the temperature of the fat drops too far and excessive recovery time required.

CAUSE

Insufficient gas supply to unit, supply lines need correction.

Ventilating system pulling heat out of the Heat Exchanger and Flue Box Ventilating system required correction.

Pilot won't stay lit, shuts off fryer.

Rapid fat breakdown, crumbs and specks in fat.

Flue blockage, burner flames not drawing in the tubes, remove blockage and check venting.

Overloading capacity, need larger fryer.

Defective thermopile or loose or dirty connection in thermopile.

Defective safety shut off valve.

Pilot burner orifice and air openings need cleaning.

High limit shut down (See High Limit Control Instructions).

Millivolt and Millampmeter required to check above or use replacement thermopile valve.

Excessive temperature settings (over 375º).

Fat not being filtered regularly.

Incorrect preparation breaded foods.

– Don't use salt.

– Alllow breading time to adhere to foods.

– Loose flour falls into fat from hands.

Don’t add strainings or drippings from meat fats to kettle fat.

Dirty fry kettle, sludge and carbon build-up gives bad taste and hastens breakdown.

Leaking kettle.

Take out 10 to 15% of the frying compound and fill with fresh frying compound. Use compound taken out in other cooking. Keeps acid buildup down.

Check thermostat settings with thermometer in kettle periodically. Thermostat may become out of calibration and give excess temperature at low settings.

Frying oil will follow metal surfaces up and down. Foam over by worn out fats permit oils to drip from kettle surfaces giving appearance of leak.

Careless draining procedure without turning off burners to prevent operation with empty tank, damages tank joints.

Carbon build up in dirty kettles causes rapid attack on kettle by promoting acid formulation.

114590-9
