MARKET FORGE MT-25 (01) PDF MANUAL

All kettles must be supplied with steam from a generator which is remotely located. Consult steam generator information or instruction plate and complete all start-up instructions. Proceed with kettle operating procedure as follows:

1. Check pressure gauge of steam supply source to insure steam input is at 15 PSI (1.0 kg/cm²). For direct connected steam, turn on external steam supply valve.
2. Check that Draw-Off Valve is tightly closed.
3. Lift kettle lid and place either a Solid or Perforated Drain Disc over the drain inside kettle. Use solid disc to retain liquids; perforated to strain liquids from food.
4. Load kettle with foods to be cooked.
5. Add water for cooking by swinging spout over kettle and using Combination Faucet.
6. Turn Steam Control Valve to full counter-clockwise position to heat kettle content to an initial rapid boil.
7. Adjust subsequent cooking temperature by turning Steam Control Valve. Turn clockwise to reduce heat and counter-clockwise to increase.
8. Close Steam Control Valve (full clockwise position) when cooking is complete.

FOOD MUST EITHER BE REMOVED FROM THE KETTLE IMMEDIATELY OR COOLED BY A KETTLE JACKET COOLING SYSTEM TO PREVENT OVER COOKING.

With Pan Support mounted (see section pan support mounting tilting kettles, on page 4), food pan in support, and Crank installed in front of cabinet, turn crank clockwise to elevate kettle for pouring. (Tilting mechanism is infinitely adjustable and non-coasting in kettle elevation and lowering). Liquid foods may also be removed by use of the Draw-Off Valve as explained in step 11 for stationary kettles.

As with cleaning food soil from any cookware, an important part of kettle cleaning is to prevent foods from drying on. For this reason cleaning should be completed immediately after cooked foods are removed. If time can not be allotted for immediate complete cleaning the kettle should be soaked by filling it with warm detergent water solution.

Cleaning:

1. Wash the kettle with a long handled nylon bristle kettle brush (Part No. 10-5308).
2. Empty wash water by opening Draw-Off Valve over Swing Drain.
3. Remove Drain Disc (solid or perforated) from inside kettle and clean.
4. Rinse kettle by flushing with hot water from the Swivel Spout.
5. Loosen hex nut on Draw-Off Valve and carefully remove all parts. Clean and reassemble (see figure 11, on page 17).

Rotate Swing Drain to left and push up off drain assembly. Clean drain and screen. Reassemble on kettle.

For convenience during cooking, the pan support need not be installed until needed for removing food from the kettles. To Insure correct operation and to prevent spills the support must be securely installed as shown in Figure 1 and as explained below:

1. Hold the pan support in front of the upright as shown at A.
2. Place the stud of the left-hand support upright into the hole in the left side of the pan support. Then push the right side of the support in until it engages the spring loaded pin of the right-hand support upright, shown at B.
3. Rotate the pan support upward (C) and engage the slotted ends of the support links in the studs at the base of each support upright as in D.

The removal procedure is the reverse of installation with the exception that in step 2 support upright springs must be pushed out to release the support from studs.

1. Check pressure to ensure that boiler is up to operational pressure of 10-12 PSI (0.7-0.8kg/cm²).
2. Check that draw-off valve is tightly closed by turning it clockwise.
3. Place solid disc or perforated disc in drain opening inside kettle.

NOTE: Use solid disc if liquid is to be retained; use perforated disc if liquid is to be discarded.

1. Fill kettle to desired level with food to be cooked or water from hot and cold fill faucet (Figure 2, No. 1).

NOTE: Refer to Cooking Guide (page 10) for cooking procedures that address individual food products.

1. Turn kettle steam control valve (Figure 2, No. 2) counterclockwise to full ON position for faster results.

NOTE: The volume of steam going into the kettle jacket can be controlled at any time by adjusting the kettle steam control valve in either direction.

1. When food is cooked, turn steam control valve clockwise to stop steam flow. Remove food immediately to prevent over cooking.
2. Prior to removing foods from kettle, the pan support should be placed in a position to establish a firm support for receiving pan.

1. Fill kettle with water and mild detergent immediately after removing food from kettle.
2. Scrub kettle interior with a nylon brush.

NOTE: NEVER SCRAPE KETTLE INTERIOR WITH METAL TOOLS, STEEL SCOURING PADS OR ABRASIVE CLEANERS. Scratches will result, which will ruin the kettles general appearance and make it harder to clean and maintain in a sanitary condition.

1. Loosen food which is stuck to kettle by allowing it to soak. Also, a small amount of steam may help.
2. Position swing drain under draw-off valve. Open draw-off valve to drain soapy water.
3. Wipe down exterior, rinse and dry. Avoid getting water into electrical controls.

WARNING: DO NOT HOSE DOWN UNIT AS IT MAY CONTAIN ELECTRICAL COMPONENTS.

1. Remove strainer from inside kettle. Wash and rinse thoroughly.
2. Disassemble draw-off valve by first turning valve handle counterclockwise. Then, turn hex nut counterclockwise until valve handle and stem are free.
3. Wash inside of draw-off valve with a nylon brush.
4. Rinse kettle valve interior and reassemble valve.

NOTE: Leave draw-off valve open when kettle is not in use.

1. Remove swivel drain and its strainer. Wash, rinse and replace.

• Estimate actual cooking capacity of Steam Jacketed Kettles at 3,4 of its volume, to allow stirring without spillage.
• Plan an adequate drain arrangement. This is very important for ease of use and to minimize wet floors. A grated gutter type drain located in front of the kettles is preferred as it eliminates the hazards of tripping over a curb or stumbling into a recessed drain area.
• Locate a source of water (swivel faucet or flexible hose type) near the kettle to facilitate filling and cleaning.
• Cover products whenever possible to save energy. Covered water boils 25 to 30% faster.
• Use the tangent draw off valve to drain off products from the kettle such as sauces and puddings, or cooking liquids that are being discarded (as in the case of the water used to cook pasta)

This chart merely shows single load capacities as it is felt that in most cases the kettle would be used only once per meal.

* All main entree figures are given in terms of raw ingredients.

The screw assembly should run smoothly throughout the entire stroke. If operation is not uniform, remove the screw assembly and proceed as follows:

1. Inspect screw shaft for accumulation of foreign matter in the ball grooves.
2. Using cleaning fluid or solvent, remove dirt from ball grooves. Be sure to flush the ball nut assembly thoroughly.
3. Cycle the ball nut along the screw shaft several times. Then, wipe with a dry, lint less cloth and lubricate immediately.

Side and rear panels of all cabinets in which kettles are mounted are easily removed without the use of tools. Each panel is grasped at the bottom edge and lift up and out towards you to release it from the panel mounting brackets.

Replacement is completed by pushing panel up under cabinet top allow hook to fall in place at the bottom until panel mounting brackets are engaged. Door may be removed to improve access to cabinet interior for repairs.

The two flat head screws and nuts holding cabinet hinge are removed and the door lifted out. When doors are remounted the final tightened position of hinge determines the alignment of the door and must be set with care.

To repair a valve leak, the source must first be determined. Leaks from around the valve stem are corrected by replacing the rubber “0” ring .Dripping from the valve outlet which occurs with the valve tightly closed indicates faulty seating of the valve disc against the valve seat. Dripping is often corrected by cleaning residue from disc and seat using very fine emery.

Should either the disc, or seat be found damaged it is necessary to either replace the entire valve or perform the lapping procedure as follows:

1. Disassemble the valve and clean both the disc and the valve seat.
2. Attach the handle to the stem with the valve bonnet removed.
3. Apply a good grade of fine lapping compound to the disc and insert it into the valve to make light contact against the seat.
4. Rotate the stem disc against the seat by turning the handle, allowing the stem to wobble in the space the bonnet would normally occupy. Continue with light pressure until compound dries.
5. Reassemble and test for leaks with valve closed. If dripping occurs repeat the lapping procedure as many times as required to obtain a watertight seal.

Lubrication of the tilting mechanism is the only required preventive maintenance other than daily cleaning. Inspect the screw of the tilting mechanism annually for adequate lubrication.

Should screw appear “dry” apply a good grade of ball bearing grease directly on the threads so that the threads appear to be barely damp. If mechanism fails to run smoothly (see tilting mechanism maintenance below).

Preventive maintenance may be performed by maintenance personnel at the establishment in which the kettle is installed.

The most important preventive maintenance operation on the steam jacketed kettle is the cleaning procedure after each use. Additional preventive maintenance operations are presented in this section.

All kettle cleaning procedures should be faithfully completed by the end of each day’s operation. (refer below for daily cleaning procedure). In addition, cabinet doors, top, fixtues, kettle lid, etc., should be washed and rinsed to remove all food spills.

1. Fill kettle with water and mild detergent immediately after removing food from kettle.
2. Scrub kettle interior with a nylon brush.

NOTE: NEVER SCRAPE KETTLE INTERIOR WITH METAL TOOLS, STEEL SCOURING PADS OR ABRASIVE CLEANERS. Scratches will result, which will ruin the kettles general appearance and make it harder to clean and maintain in a sanitary condition.

1. Loosen food which is stuck to kettle by allowing it to soak. Also, a small amount of steam may help.
2. Position swing drain (refer to figure above) under draw-off valve. Open draw-off valve to drain soapy water.
