IMPORTANT NOTES FOR OPERATORS

CAUTION: Cleanandflush the kettle immediately after use, especially if the item cooked contained salt or vinegar in any concentration. The jackets are constructed of Type 304 Stainless Steel but can pit or corrode under adverse conditions, andprompt, careful cleaning will help prevent such.

CAUTION: The draw off faucetplugandbody aremade of relatively soft dairy metal. The plugmust behandled with care to prevent damage to its tapered surface which would prevent it from seating properly in the body thus causing the faucet to leak. A light lubricant (cooking oil) on mating surfaces of plug and body will prevent a sticking plug. An aerosol can of asuperior dry lubricant is available from Vulcan-Hart (see parts list).

On manually controlled units, steam flow to unit is controlled by two valves in parallel lines. The large valve gives a high steam flow rate for rapid heat up. With the large valve closed, the small valve allows accurate control of low steam flow rates required for maintaining thesteady simmer boildesired forcooking.

On thermostatically controlled units, steam flow is controlled by a solenoid valve in the steam line; the valve is open only when its coil is energized. The solenoid coil, the thermostat switch and the pressure limit switch are wiredin series and connected to power thru the two-pole on-off switch to which the cord and plugsupplies 120 volt AC power. One signal lightglows when the on-off switch to which the cord and plug supplies 120 volt AC power. One signal light glows when the on-off switch is on,the other signal light glows only when the solenoid valve is energized. The thermostat senses temperature in the steam jacket. At dial setting 5 to 6, the thermostat switch will open and stop steam flow when jacket pressure starts to exceed zero gauge pressure. The high dial settings are for cooking, the lower settings for holding. At the higher dial settings, the steam pressure in the jacket will drop 2 to 2½ p.s.i. after the thermostat acts to cut the steam off before it acts to cut the steam on. The pressure limit switchis anaddedsafety feature. It acts to de-energize the solenoid valve should jacket pressure reach 12 p.s.i., and will close again only when jacket pressure drops below 3 p.s.i.

A mounted pressure gauge is provided to show steam pressure in the jacket.

The pressure relief valve is a deviceto protect thekettle against excessive presure. The pressure relief valve will open and reduce jacket pressure since it will pass steam at a higher rate than the supply piping will deliver it.

The vacuum check valve prevents a vacuum in the jacket which could damage the outer jacket.

The automatic air vent lets air out of the jacket as steam enters but closes to prevent steam escape.

USE, CARE, CLEANING & PERIODIC MAINTENANCE

USE

This food draw-off valve is designed to allow food and liquid to be drawn-off from kettle in an easy and depend­ able manner.

OPERATION

When the food draw-off valve is turned off (no liquid or food product flow), the valve handle wiIIpoint 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 90° turn, right or left, to close off food flow. To allow for evenly mixed food products to flow into a food service pan or stock pot, you should first stir the food product load in the kettle thoroughly before opening the food draw-off valve to allow the food to flow. Pans or pots may be placed on a portable dolly for easy move­ ment and handling.

CLEANING

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 during July 2003 thru March 1992 – this removable position is with the valve handle at the 4 o’clock position. Kettles built before March 1992 – the removable position is at 6 o’clock.

IMPORTANT: (Do not attempt to slide valve plug into valve body when valve handle is in any other than it’s removable position. This willdamage the pin and the plug will not seat properly causing leakage between the valve body and plug.) Using warm soapy water, wash the entire valve body and open area into kettle interior. Also, 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 dairy metal.

Caution: Lubrication must be done every day after use. After washing, lubricate the valve body and valve plug with Petro-Gel or a like and equally sanitary lubricate. Make sure all interior mating surfaces are covered with this lubricate before carefully sliding the valve plug into the valve body. Caution: Make sure the valve plug handle is in it’s removable position when the plug is slipped carefully into the valve body.

NOTE: A 4 oz. tube of Petro-Gel Lubricant is furnished free of charge with your kettle. You can reorder through your service agency or food service equipment dealer. There are no substitutes for this lubricant. If you are offered a substitute, make sure it is a like and equal product that is both sanitary food safe and will not break down when the kettle is brought to cooking temperature.

CAUTION

Each draw-off valve body and removable tapered draw­ off plug is stamped with aset of corresponding numbers.

After cleaning, make sure the body and plug numbers match before reinserting the tapered plug.

Always examine the valve plug and valve body for nicks and any heavy scratches. Do not attempt to push or force the valve plug into the valve body if there is any obstruction, nicks or heavy scratches in either the plug or body.

To correct a badly leaking draw-off valve (leaking after lubricant applied), examine the tapered surface of each and carefully dress any raised places with a very fine file or with emery cloth. Do not cut below the metal surface when removing any raised places. Coat plug lightly with lapping compound, insert plug in body and rotate to seat plug in body. Use a medium grade of lapping compound first and finish with a fine grade of lapping compound. Valve grinding compound from an automobile supply house is suitable for this.

Clean surfaces thoroughly after use of lapping com­ pound. Lubricate surfaces with non toxic Petro-Gel to prevent the plug from sticking.

WARNING

If the food draw-off valve plug and inside of the valve body are not lubricated, undesirable leakage can occur or (VERY IMPORTANT) when the kettle is up to cooking temperature and the operator attempts to open the draw­ off valve, the valve plug could stick in a partially open position.

NOTE: The food draw-off valve is bolted to the kettles so it can be easily removed from the empty kettle for complete inspection or if repair becomes necessary.

SERVICE PROCEDURES

TO CORRECT LEAKING DRAW OFF FAUCET

Remove plug from body of faucet. Examine tapered surface of each and carefully dress and raised places with very fine file or emery cloth. Do not cut below surface in removing any raisedplaces. Coatpluglightly with lapping compound, insert plug in body and rotate to seat plug in body. Use medium grade of compound first and finish with a fine grade of lapping compound. Valve grinding compound from an automobile supply house is suitable for this.

Clean surfaces thoroughly after use of lapping compound. Lubricate surfaces lightly (with non-toxic lubricant) to prevent plug from sticking.

Faucet plug is best lubricated with easily applied dry tape lubricant in aerosol can offered by Vulcan-Hart (see parts list). To use, spray a light coating on mating surfaces of faucet plug andbody andallow to dry for 10 minutes. The lubricant prevents the plug from sticking and helps prevent leaky faucets. It is nontoxic and fully safe. Cooking oil may be used to lubricate the plug, but the dry lubricate is much more effective.

ON THERMOSTAT CONTROLLED UNITS ONLY TO SERVICE THERMOSTAT

To recalibrate, remove dial by pulling it forward, and slightly turn the small screw in center of hollow dial shaft.

Recalibration is indicated if thermostat with dial at highest setting fails to shut off burners before pressure relief valve opens or if it shuts burners off before jacket pressure reaches 8 p.s.i.

To replace thermostat, remove two screws under dial, disconnect wire leads, unscrew packing gland around capillary tube where it enters jacket, unscrew bushing into which gland was threaded and pull bulb from jacket. In installing new thermostat, insert bulb first. Be careful that capillary tube is not bent sharply, that packing glandsealis pressuretight, andthat wire leads are clean and terminal screws are tight.

ON THERMOSTAT CONTROLLED UNITS ONLY TO SERVICE PRESSURE LIMIT SWITCH

This service is indicated if a circuit check shows switch is not closed to allow main burners to operate, or if switch is opening at too low a pressure. It was factory set to open at 12 p.s.i. and to close at 3 p.s.i.

To remove switch for any service, disconnect tubing from bottom of unit and remove two screws with nuts which anchor the mounting bracket for the unit.

Cut out and cut in pressure setting of switch is shown by the dial andadjustable withslottedsquareshanks at top of case. Adjust cut out pressure setting first. If this adjustment does not cure trouble, replace the whole unit.
