IMPORTANT NOTES FOR ALL VULCAN APPLIANCES

1. These units are produced with the best possible workmanship and material. Proper installation is vital if best performance and appearance are to be achieved. Installer must follow the installation instructions carefully.

2. Information on the construction and installation of ventilating hoods may be obtained from the "Standard for the installation of equipment for the removal of smoke and grease laden vapors from commercial cooking equipment," NFPA No. 96 (latest edition) available from the National Fire Protection Association, Battery March Park, Quincy MA 02269.

3. For an appliance equipped with a flexible electric supply cord, the cord is equipped with a three prong (grounding) plug. This grounding plug is for your protection against shock hazard and should be plugged directly into a properly grounded three prong receptacle. Do not cut or remove the grounding prong from this plug. If the appliance is not equipped with a grounding plug, and electric supply is needed, ground the appliance by using the ground lug provided (refer to the wiring diagram).

(FOR GAS APPLIANCES ONLY)

4. Do not obstruct the air flow into and around the appliance. This air flow is necessary for proper combustion of gases and for ventilation of the appliance. Provisions for ventilation of incoming air supply for the equipment in the room must be in accordance with National Fuel Gas Code ANSI Z223.1 (latest edition).

5. Do not obstruct the flow of flue gases from the flue duct (when so equipped) located on the rear (or sides) of the appliance. It is recommended that the flue gases be ventilated to the outside of the building through a ventilation system installed by qualified personnel.

6. For an appliance equipped with casters, (1) the installation shall be made with a connector that complies with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 (latest edition), and Addenda, Z21.69a (latest edition), and a quickdisconnect device that complies with the Standard for Quick-Disconnect Devices for Use With Gas Fuel, ANSI Z21.41 (latest edition), and Addenda, Z21.41a (latest edition) and Z21.41b (latest edition), and (2) adequate means must be provided to limit the movement of the appliance without depending on the connector and the quick-disconnect device or its associated piping to limit the appliance movement. If disconnection of the restraint is necessary, reconnect this restraint after the appliance has been returned to its originally installed position.

7. The appliance 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 k Pa).

8. The appliance must be isolated from the gas supply system by closing its individual manual shutoff valve during any pressure testing of the gas supply system at test pressures equal to or less than 1/2 psig (3.45 k Pa).

To reach barrier, remove electric cover plate "A" from unit. After connecting 120V AC electric supply to fryer barrier strip, verify with a voltmeter that the following condition exists. See Detail "A".

1. Black to White 120V AC.

2. Black to Ground 120V AC.

3. White to Ground 0.00V AC. Make all other necessary electrical connections.

Improper grounding and/or polarity will result in lock out of unit and eventual damage to the ignition systems.

This unit is supplied with a 6 1/2 foot long 3 wire supply cord. This appliance is equipped with a 3 prong (grounding) plug for your protection against shock hazard and should be plugged directly into a properly grounded three prong receptacle. DO NOT cut or remove the grounding prong from this plug.

POSITIONING FRYER

GAS SUPPLY CONNECTION UNDER HOOD

SIDE ARM

See Detail "C"

All GEF Fryers are equipped with a 3.7"W.C. 3/4" reg- ulator for natural gas and a 10" W.C. 3/4" regulator for propane gas.

To connect unit to gas supply, attack quick disconnect supplied with unit to male fitting as follows:

1. Pull disconnect collar #1 back.

2. Snap disconnect #2 on to male disconnect fitting "C" supplied on unit.

3. Release disconnect collar when fitting #3 and disconnect #2 snap into place.

4. Connect union #4 to gas supply.

5. Turn main gas supply on and test for gas leakage at all connecting points.

Fryer is supplied with four adjustable height legs. Legs should be adjusted so that the fryer is level and at its proper height in the hood. See Detail — C1.

Position fryer so that it may be pushed straight back under the hood. Place main top onto fryer by tilting main top while pushing fryer under hood. After the main top has cleared the hood, position main top so that it rests evenly on the unit.

CONTROLS

SWITCH PANEL CONTROLS

(Refer to Detail "D")

1. MASTER SWITCH — Controls electric supply to unit

2. POWER "ON" LIGHT — Light indicates when electrical supply is on.

3. TEMPERATURE CONTROL — Maintain frying temperature by controlling power supply.

4. HEATING LIGHT — When "ON" indicates temperature control is calling for gas to burners.

5. HIGH LIMIT TEST SWITCH — Bypasses temperature control for testing of high limit thermostats.

6. FIRST HIGH LIMIT LIGHT — When "ON" indicates first high limit thermostat has shut down unit.

7. SECOND HIGH LIMIT LIGHT — When "ON" indicates second high limit thermostat has shut down unit. (Reset required*)

8. TROUBLE LIGHT — Indicates solid state ignition device has "locked out". (Reset required*)

9. IGNITOR RESET BUTTON *NOTE: To reset, turn main power switch off, then on.

— See Detail "D" — When up indicates excessive heat or current in control board, allow to cool push

down to reset. If tripping continues, contact service agency.

OPERATIONAL LIGHTING INSTRUCTIONS:

To turn on, push power switch to "ON" position; turn thermostat dial to temperature desired. To turn off, push power switch to "OFF" position.

NOTE: Service valve must be in "ON" position and

power cord connected to power source for unit operation. For service or extended shut down, turn service valve to

"OFF" and disconnect power cord. The above information may also be found on the inside of

fryer door panel.

AIR ADJUSTMENT

HIGH LIMIT TEST

A blue flame seen out of the viewing port indicates insufficient air. To correct this condition, remove plug button from air adjustment plunger opening. Using a 1/8" allen wrench, remove two set screws 1/4-28 NF X 3/8" Long (one from each opening).

Replace allen wrench back into each opening and rotate wrench counterclockwise to reduce flame in viewing port and clockwise to increase flame. The air adjustment has been properly made when flame is not seen out of the viewing port and a maximum red glow is achieved on the burners. (See Detail "B")

CLEANING BLOWER INLET SCREEN AND WHEEL

For preventative maintenance and maximum performance of the blower motor, the inlet screen and blower wheel should be cleaned once a month as follows:

1. Turn power switch "OFF".

2. Remove two (2) wing nuts from side of blower motor.

3. Remove blower inlet screen.

4. Remove blower wheel.

5. Soak blower inlet screen and wheel in mild soap and water solution. Dry thoroughly before replacing parts.

6. Reassemble screen and wheel to unit, and tighten wing nuts.

7. Turn power switch to "ON" position and resume unit operation.

PROCEDURE

A test to determine if the protection devices are properly functioning. (See steps 1 thru 5)

1. Turn master switch on and set temperature knob to frying temperature.

2. Heat shortening until heating light goes off.

3. Depress top of high limit test switch and hold until first high limit comes on, then release switch. (Light will come on at 390 degrees F.-420 degrees F.)

4. Depress bottom of high limit test switch and hold until second high limit light comes on, then release switch. (Light will come on at 420 degrees F.-445 degrees F.)

5. Once unit cools down, reset by turning main power switch off and then on, normal frying operation will then automatically be resumed.

The above instructions may also be found on the inside fryer door.
