Installation, Operation and Care of

MODEL ES, EL & ET STEAM JACKETED KETTLES

KEEP THESE INSTRUCTIONS FOR FUTURE REFERENCE

GENERAL

Your Vulcan steam jacketed kettle is produced with quality workmanship and material. Proper installation, usage and maintenance will result in many years of satisfactory performance.

Vulcan-Hart Company suggests that you thoroughly read this entire manual and carefully follow all of the instructions provided.

INSTALLATION

Prior to installation verify that the electrical service agrees with the specifications on the machine data plate located inside the front cover at the lower left.

UNPACKING

This kettle was inspected before leaving the factory. The transportation company assumes full responsibility for safe delivery upon acceptance of the shipment. Immediately after unpacking, check for possible shipping damage. If the kettle is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.

LOCATION

Position the kettle in its final location. Check that there are sufficient clearances for operating and servicing the kettle, and for proper clearance of the cover when raised. The kettle draw off faucet should be located near a floor drain.

LEVELING

Place a spirit level on the rim of the kettle with the cover open. Adjust the feet to level the kettle leftto-right and front-to-back.

INSTALLATION CODES AND STANDARDS

Vulcan kettles must be installed in accordance with:

In the United States:

1. Local codes.

2. National Electrical Code ANSI/NFPA-70 (latest edition).

– 3 –

3. ANSI NFPA Standard #96 "Vapor Removal from Cooking Equipment," (latest edition), available from the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.

In Canada:

1. Local codes.

2. CSA Standard C22.1 Canadian Electrical Code, Part 1.

ELECTRICAL CONNECTIONS

WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE

APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL ELECTRICAL CODES.

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

Make required electrical supply connections at the junction box located below the control box. There is no opening in the junction box for supply line conduit. The box is a sealed box and the conduit connection should be made with fittings of the water resistant type. Be sure the supply wiring and the circuit protection are adequate for the K.W. load drawn by the kettle. The wiring diagram is located on the back side of the removable control cover. Use copper wire suitable for at least 75°C temperature.

If the kettle is for operation on an electric supply of over 240 volts, a transformer is provided to reduce the control circuit voltage to 120 volts.

OPERATION

WARNING: THE KETTLE AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING

AND SERVICING THE KETTLE.

BEFORE FIRST USE

Using a non-corrosive, grease-dissolving commercial cleaner, clean the protective metal oils from all surface parts and interior of the kettle. Follow the cleaner manufacturer's directions. Rinse thoroughly with warm water to remove all traces of the cleaner. Drain the kettle. Wipe dry with a soft clean cloth.

CONTROLS

On-Off Switch — Turns power to the kettle on or off.

Thermostat Switch, — These three switches are wired in series and control the supply of Low Water Cutoff Switch, energy to the heating elements. Opening any one of these pressure Limit Switch switches will shut off the power supply to the heating elements.

Thermostat — Senses the temperature in the steam jacket. At a dial setting of 5 to

6, it will cut power off as the pressure gauge needle moves off zero. The higher dial settings holding. At the higher dial settings, jacket will drop to 2 to 2 off and before it cuts it on.

FILLING THE WATER JACKET

APPLIANCE FAILURE CAUSED BY INADEQUATE WATER QUALITY IS NOT COVERED UNDER WARRANTY.

Fill the outer jacket of the kettle to the top of the band on the gauge glass with a chemically pure distilled water, along with a suitable rust inhibitor.

It should not be necessary to frequently add distilled water to the jacket, as little distilled water is lost in normal operation.

USING THE KETTLE

Before use, preheat the kettle empty. Set the thermostat at No. 12 or No. 13. When the orange light goes out, load food and set thermostat dial for desired cooking temperature.

KETTLE FOOD DRAW-OFF VALVE

When the food draw-off valve is turned off (no liquid or food product flow), the valve handle will point to either the 9 o'clock or 3 o'clock position. To open (allowing liquid or food product flow), slowly pull handle forward. With the valve handle pointing to the 6 o'clock position, the valve is in a fully open position. This food draw-off valve system requires a right or left turn to close off food flow.

To allow for evenly mixed food products to flow into a food service pan or stock pot, first thoroughly stir the food product in the kettle before opening the food draw-off valve. Pans or pots may be placed on a portable dolly for easy movement and handling.

CLEANING

WARNING: DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING.

After Each Use

Clean and flush the kettle immediately after each use, especially if the product cooked contained salt or vinegar in any concentration.

Daily — Kettle Food Draw-Off Valve

1. With kettle empty, pull valve handle to the 7 o'clock position. (A pin locks the valve plug into the valve body and you can only remove or replace the valve plug when the valve handle is in the 7 o'clock position.) Kettles built before July 2003 thru March 1992 - the removable position is at 4 o'clock. Kettles built prior to March 1992 - the removable position is at 6 o'clock.

2. Pull tapered plug from valve body.

3. Using warm soapy water, wash the entire valve body and open area into the kettle interior.

4. Wash the interior and exterior of the valve plug. CAUTION: Do not drop or hit the valve plug. This will nick or dent the soft metal.
