INSTALLATION INSTRUCTIONS

1.These instructions must be retained by the owner/user

for future reference. Gas-fired boilers are only to be installed in noncombustible areas that have provisions for adequate air supply. The term "boiler'' will be used synonymously with "steam generator"

2. Position: For proper operation and drainage, the

equipment must be level It should be placed next to an open floor drain. DO NOT POSITION THE UNIT DIRECTLY ABOVE THE FLOOR DRAIN. Observe all clearance requirements to provide air supply for proper operation. as well as sufficient clearance for servicing. The surrounding area must be be free and clear of combustibles. Dimensions and clearance specifications are shown on the specification sheet.

3. Install in accordance with local codes and/or the

National Electric Code ANSI/NFPA No. 70-1987. Installation in Canada must be in accordance with the Canadian Electrical Code CSA Standard C22.1 Equipment that is connected to electricity must be grounded by the installer. A wiring diagram is provided inside the base cabinet.

4. The dram line outlet discharges exhaust steam and hot

condensate. Connect 1-1/2-inch. IPS piping (or larger) 10 extend the dram line to a nearby open floor dram. Up to two elbows and six feet of 1-1/2-inch IPS (or larger) extension pipe should be connected to the drain termination. Drain piping extended six to twelve feet or using three elbows, should be increased to 2-inch IPS No more than two pieces of Cleveland Range equipment should be connected to one common drain line. The

maximum length of extension from the dram

termination should not exceed six feet and use no more than two elbows. The extension piping must have a gravity flow and vent freely to the air. This drain outlet must be free-vented to avoid the creation of back pressure a the steamer cooking compartments. To ensure a vented drain line, DO NOT, UNDER ANY CIRCUMSTANCES, CONNECT THE DRAIN OUTLET DIRECTLY TO THE FLOOR DRAIN OR SEWER LINE. Do not run the drain line discharge into PVC drain piping or any other drain piping material not capable of sustaining 180 F operation.

NOTE Direct steam connected pressure steamers do not

require a cold water connection, and therefore steps 5 and

6 do not apply. Refer directly to step 7. A kettle fin faucet, if so equipped, requires a hot and/or cold water connection. The data contained in step 5 for cold water also applies to hot water.

5. Connect COLD water supply plumbing to the line strainer.

(Never connect hot water 10 the boiler-water fill line strainer.) Constant flow pressure must he maintained

between 35 and 60 psi, and not experience a pressure drop below 35 psi when other appliances are used. If the water pressure exceeds 60 psi, a pressure reducing valve must be installed in the water supply plumbing 10 reduce the water pressure 10 less than 60 psi. Locations and pressure data are shown on the specification sheet, 1/4-inch IPS plumbing is sufficient for water supply lines up to 20 feet in length, but water supply lines longer than 20 feet should be at least 3/8-inch IPS. Flush water supply lines thoroughly before connecting them 10 the unit Use water which is low in

anal dissolved solids content and low in gas content to prevent internal scaling, pitting and corrosion of the steam generator, and carry -over of minerals into the steam. Water which is fit to drink, can still contain highly detrimental impurities.

NOTE: If equipped with a kettle and kettle water fin swing

spout, 3/8-inch (10mm) not and/or cold water

connections) win be required at the swing spout valve.

6. Turn on the cold water supply to the unit. Ensure that the

Convection Steamer

CARE AND CLEANING

The Cleveland Convection Steamer must be cleaned regularly to maintain its fast, efficient cooking performance, and to ensure its continued safe, reliable operation.

1. The boiler must be drained (Blowdown) after a maximum of 8 hours of use. If the boiler feedwater contains more than 60 pans per million of total dissolved solids, the boiler must have a blowdown more often, the frequency depending upon the mineral content of the feedwater. Blowdown means the boiler must be drained under pres-sure.

THE BOILER BLOWDOWN IS PERFORMED BY SIMPLY SHUTTING OFF THE STEAMER'S REDLIGHTED POWER SWITCH WHILE THE BOILER IS AT NORMAL 10 PSI OPERATING PRESSURE. WHEN THE BOTTOM OF THE POWER ROCKER SWITCH IS PRESSED, ITS RED LIGHT GOES OUT, AND THE DRAIN VALVE AUTOMATICALLY OPENS, DRAINING THE BOILER. AN AUTOMATICALLY-TIMED DRAIN

WATER CONDENSER WILL FLUSH THE DRAIN FOR 3

MINUTES, THEN SHUT OFF. AFTER 3 MINUTES THE STEAMER IS READY TO BE RESTARTED.

When steam is produced, the water in the boiler is being

the boiler with the water, remain in the boiler as the water boils away as steam. When allowed to accumulate, the

water becomes highly mineralized, which results in erratic

operation, lime build-up corrosion, and premature electric heater failures. In some cases, complete boiler replacement becomes necessary, which is extremely ex-pensive. By draining the boiler under pressure, most sedi-meat present will be flushed down the drain.

2. The steamer is equipped with a drain in the back of the cooking compartment. No compartment should be operated without the drain screen in place. This screen prevents large food particles from entering and possibly plugging the drain line. Any restriction of the drain line may cause a slight build-up of back-up pressure in the compartment, resulting in steam leaks around the door gasket. It also may adversely affect the convection action of the steam in the compartment, which is critical to optimum performance. Pouring USDA approved drain cleaner through the compartment drains once a week will help to ensure an open drain. A manual (hand crank) drain auger, or "snake'', may be safely used to clear obstructions in the compartment drains. Do not use a power auger, as damage to the plastic drain system will result.

With the steamer off open the cooking compartment doors and allow the steamer to cool before cleaning the cooking compartments and their compartments.

3. At the end of each day's operation, wash the pan slide's, steam tubes, door gaskets, and compartment interiors with mild detergent and warm water, either by hand or in a dishwasher. Rinse thoroughly with clear water. Rinse water should drain freely through the compartment drain

opening. If it does not, the drain must be cleaned before using the steamer.

4. Once a week, remove the steam robes and clean the orifices. First, remove the pan slides by lifting upward and toward the center of the compartment. Pressing backward on the steam tube will allow its front eyelet to clear the compartment stud. The tube is then angled toward the center of the compartment just enough to clear the stud and be pulled forward, out of its socket. The orifices can be cleaned easily with a paper cap. Then. thoroughly wash and rinse all steam tubes. This can be done m a dishwasher. Lubricate each tube's tapered end with cooking oil before replacing in the steamers compartments. Be sure all four steam tubes are securely in place before activating the compartment. The tubes are interchangeable and may be placed m any spot m either compartment.

5. To prolong door gasket always leave compartment door ajar when not in use.

6. Exterior Care: Allow steamer to cool before washing. Use the same cleaners and cleaning procedures as for other kitchen surfaces of stainless steel and aluminum. Mild soapy water, with a clear water rinse, is recommended. Do not allow water to run into electrical controls. Always turn off equipment power before using water to wash equipment. Do not hose down the steamer.

WARNING

Do not store or use gasoline or other flammable vapors and liquids in the vicinity extras or any other appliance.

MAINTENANCE

Periodically, a qualified serviceman should be

summoned for routine preventive maintenance.

1. The blowdown procedure will not completely remove the mineral deposits that adhere to the top of the boiler. A chemical descaling should be done by a boiler treatment specialist. This should be done once a year in average water conditions, but in poor water areas it may be needed two or three times a year.

2. Periodic boiler inspection should be made by a qualified serviceman.

3- Once every three months, the cold water line strainer

should be cleaned.

Cleveland Ranges supports a comprehensive network of Maintenance and Repair Centers (regional pans and service distributors) throughout the United States and Canada. Please contact your nearest distributor for the name of an authorized service agency in your area, or for replacement pans and information regarding the proper maintenance and repair of Cleveland Range equipment. In order to maintain the various agency safety certifications, only factory -supplied replacement parts should be used.

DIRECT STEAM KETTLE

OPERATION

Ensure that there is an adequate steam supply to the kettle.

Turn the steam control valve to the fall open position by turning the knob counter-clockwise, then allow the kettle to pre-heat.

NOTE: "When cooking egg and milk products, the kettle should NOT be preheated, as products of this nature adhere to hot cooking surfaces. These types of foods should be placed in the kettle before hearing is begun.

Fill kettle with product to desired level

"When the produce has reached the desired temperature, regulate the heat, as required, by turning the steam control valve for less steam and therefore, a lower temperature.

When cooking is complete, dose the steam control valve by turning the knob.

For kettle/steamer combinations: If the boner in a steamer is supplying steam to a kettle, always heat the kettle first. After the kettle contents are heated, and the boiler's steam pressure returns to normal the steamer may be used. Pressure steamer compartments should be sequentially started, and preheated before cooking.

NOTE: As with cleaning food soil from any cookware, an important pan of kettle cleaning is to prevent foods from drying on. For this reason, cleaning should be completed immediately after cooked foods arc removed. Please refer to the "Care and Cleaning instructions for detailed kettle washing procedures.

CARE AND CLEANING

Your kettle must be cleaned regularly to maintain its fast, efficient cooking performance, and to ensure its continued safe, reliable operation.

WARNING: Do not use chlorine base detergent.

1. Prepare a warm water and mild detergent solution in the kettle.

2. Remove food son inside- die kettle using a nylon brush, Do not use a metal bristle brush, as this may permanently damage the kettle's stainless steel surface.

3. Loosen food which is stuck to the kettle by allowing it to soak at a low temperature (simmer or low boil).

4. Tilt kettle forward to drain the •wash water.

5. Rinse the kettle interior thoroughly, then drain rinse water.

6. Leave the cover and draw-off valve open when the kettle is not in use.

7. Using mud soapy water and a damp sponge, wash the exterior of the kettle, rinse, and dry.

NOTE: For more difficult cleaning applications, one of die following can be used: alcohol, baking soda, vinegar, or a solution of ammonia in water. Avoid the use of chloride cleansers, which may damage the kettle's stainless steel surface.

WARNING: Steel wool should never be used for cleaning the cooking chamber of the kettle. Particles of steel wool become embedded in the cooking surface and rust, and may corrode the stainless steel.

SERVICING GUIDE

This section contains information intended for use by Authorized Service Personnel only.

A/ PROBLEM : Kettle heats too slowly or does not come to a boil.

Probable Cause Remedy

1. Inadequate steam flow. Check for correct steam using chart below. If kettle is connected to a -steamer and powered by a generator the units should be operated sequentially (kettle boiling first, then start steamer).

2. Steam trap not operating property. The trap should open periodically to dump condensate, then close, If it does not open or dose it should be cleaned or replaced.

3. Food batches are not always the same. When checking make certain that the original state (ie. fresh or frozen) and quantity of food product is the same.

B/ PROBLEM : The trunnion housing leaks steam.

Probable Cause Remedy

1. Trunnion "O" rings are worn. Replace "O" rings.

STEAM GENERATOR (2 PROBE TYPE) MAINTENANCE PROCEDURES

CAUTION: Service on the generator must be performed only by a trained and experienced service technician, thoroughly familiar with servicing steam generators. No work should be done on the steam generator while it is pressurized or hot Be sure all energy sources are shut off before the start of any work.

The steam generator must be drained under pressure (blowdown) after a maximum of 8 hours of use. It the generator's feedwater contains more than 300 parts per million of total dissolved solids, the generator must have a blowdown after each 46 hours of use. "Blowdown" means the generator must be drained under pressure.

THE GENERATOR "BLOWDOWN" IS PERFORMED BY SHUTTING OFF THE UNITS RED-LIGHTED "POWER" SWITCH WHILE THE GENERATOR IS AT NORMAL OPERATING PRESSURE. WHEN THE BOTTOM OF THE "POWER" ROCKER SWITCH IS PUSHED. ITS RED LIGHT GOES OUT. AND THE DRAIN VALVE AUTOMATICALLY OPENS, DRAINING THE GENERATOR. AN AUTOMATICALLY-TIMED SOLENOID VALVE WILL FLUSH THE DRAIN FOR 3 MINUTES. THEN SHUT OFF. AFTER 3 MINUTES. THE UNIT CAN BE RESTARTED.

Even though the "Blowdown" is performed faithfully each day. it will still be necessary to have a qualified service technician periodically inspect the inside of the generator for scaling or pitting. The generator's hand hole plate should be removed at regular intervals, so that it and the inside of the generator can be inspected. The hand hole plate should be cleaned and examined each time it is removed. If the hand hole plate is chipped or cracked, or over three years old, install a new one. A new hand hole gasket should always be installed.

Scaling indicates a high concentration of dissolved minerals in the feed water. Pitting indicates an excess acid condition. The best way to reduce servicing time and to assure a long generator life is to provide feed water that is low in mineral content and low in gas content. Water that is fit to drink can still be high in impurities that are highly detrimental to a steam generator. Consult the state department of water for an on-the-premises water analysis and for recommendations concerning steam generator feed water treatment (if required), in order to remove or reduce harmful concentrations of minerals.

CAUTION: Never tighten the hand hole plate nut when the steam generator is in use, hot, or otherwise pressurized. Never tighten nut over 15 foot-pounds torque. Over tightening may cause uneven stress, which may result in the weakening and possible breakage of the plate.

The "Blowdown" procedure will not completely remove the mineral deposits that adhere to the top of the generator. It will be necessary to periodically have scale accumulations removed from the inside of the steam generator by a qualified

service technician. Only a U.S.D.A. approved acid cleaner should be used to descale the generator. Descaling should be done once a year. but in poor water (highly mineralized) areas it may be needed two or three times a year. Failure to periodically remove scale from the inside of the generator will result in greatly reduced generator life. Check the safety valve once a month while the steam generator is pressurized. Test by pulling the safety valve lever. The

valve must open freely and snap closed when released. If it does not. or if it drips constantly, a new safety valve is needed. If the steam generator is to be left idle for three months or more. it should be drained and dried out and the hand hole plate left

off.

WATER QUALITY REQUIREMENTS — 2-PROBE TYPE STEAM GENERATOR PROTECTION AND MAINTENANCE

A steam generator, or boiler". unlike other types of water-using kitchen equipment distills the water in order to make steam. Nearly all feed-water sources contain dissolved minerals in varying degrees of concentration. As this water is boiled, pure steam rises from its surface. upward to the cooking compartment(s). leaving minerals behind, that can become harmful to the steam generator. If minerals are allowed to accumulate inside the steam generator. they will solidify as a scale. Then. malfunctioning will occur, and serious equipment damage may result

The use of good Quality generator feed water is the responsibility of the owner/user. The use of poor quality feed water could void equipment warranties. The mini-mum treatment required in most areas is water softening, although local water conditions may require more in tensive pretreatment than simply a water softener.

Scale problems occur when feed water is high in hardness. total dissolved solids, silica, and alkalinity. Water softening will only reduce the water's hardness, which is the presence of dissolved salts of magnesium and calcium. Water softening will not affect the multitude of other minerals found in most water supplies. Because generator scale is the result of the precipitation of many minerals. the best property to control, for generator feed water, is total dissolved solids, not just hardness.

The recommended minimum water quality standards. whether untreated or pre-treated. based upon 8 hours of use per day. and a Daily Blowdown are as follows:

TOTAL DISSOLVED SOLIDS less than 60 parts per million TOTAL ALKALINITY less than 27 parts per million SlLICA less than 13 parts per million pH FACTOR greater than 7.5

Consult the state department of water or a local water treatment specialist for an on-the-premises water analy sis and for recommendations concerning steam generator teed w ater treatment (if required), in order to remove or reduce harmful concentrations of minerals.

If the recommended water quality requirements are met without supplemental treatment or if treatment is applied. resulting in feed water quality meeting the prescribed standards, the steam generator will need to be blown down only once every 8 hours. In addition. the inside of the generator requires an inspection (for excessive lime accumulation) only once every six months. Chemically descale the generator as required.

If a ore-treatment unit cannot be installed, and the recommended water quality requirements are not met the following procedures should be followed, in order to achieve maximum steam generator service life. The steam generator should be blown down after each 4-6 hours of use. Have the steam generator inspected, inside and outside, by a qualified technician every three months. If the inside of the generator is heavily coated with scale. have it chemically descaled by a qualified service technician.

INSTRUCTIONS FOR CHEMICALLY DESCALING 2PROBE TYPE STEAM GENERATORS

WARNING: Steam under pressure may cause serious

injury and bodily harm when it is acciden| tally or carelessly released. Improper handling I of acid could cause serious, permanent injury. Therefore, service of the steam generator should only be performed by trained and experienced personnel, thoroughly familiar with servicing generators.

There are a number of commercial descaling chemicals available, produced by various manufacturers. Those utilizing a sulfamic acid base, which can be identified by its powdered form are safe and compatible with our food preparation equipment it is imperative that the acid used for descaling be FDA approved, for use in food preparation equipment Various manufacturers may include additional chemicals to increase potency, and therefore. instructions for a specific brand should be followed care-fully If instructions are not provided with the deliming chemical you purchase, the following general guidelines may be followed.

WARNING: Exercise care when handling acid. Avoid contact with skin, eyes, or clothing. Wear safety glasses or face shield, along with rubber gloves and rubber apron. In case of exposure to clothing, remove clothing and flush with water. In case of exposure to skin or eyes, flush with

water for 15 minutes and get immediate medical ; attention. Do not take internally. Keep out of the ' reach of children.

Be sure the generator has been drained, de-pressurized: and is cool. Open the hand hole access plate on the front of the generator and place approximately 8-10 pounds of sulfamic acid inside the generator. Put a new hand hole gasket on the hand hole plate, and replace the hand hole plate, tightening the bar and nut assembly to a maximum of 15 foot pounds torque. The generator must be completely filled with water (fill the generator beyond its normal, automatic fill point of 2/3 up in the sight gauge). This can be accomplished by temporarily disconnecting the wire from the water level probe at the water level control board. The board is marked "HI" at this connection point Turn the main on-off rocker switch to the "ON" position, then close the manual water feed valve when the generator is completely filled- Leave the on-off rocker switch in the "on" position to prevent the generator from automatically draining. Reconnect the probe wire to the "HI" terminal of the water level control board. Let the solution stand for several hours, then flush with water. Rinse with a solution of bicarbonate of soda to neutralize any acid residue, and again, flush with water. Be sure to reconnect the wire to the water level control board and to open the manual water feed valve.

CAUTION: Never tighten the hand hole plate nut when

the steam generator is in use, hot, or otherwise

pressurized. Never tighten nut over 15 foot pounds

torque. Over tightening may cause uneven stress, which

may result in the weakening and possible breakage of the

plate.

WATER LEVEL CONTROL SYSTEM

TROUBLESHOOTING AND REPAIR

General Description of Operation: The Cleveland Range water level control, P/N 23198, is designed to maintain operating water level in

Cleveland Range steam generators and to ensure that the beat source is only operated when the generator water level is above a specified minimum level. The sensing technique for the control relies on the fact that tap water is conductive to electricity; if two metal electrodes are immersed in a bath of water, electric current can flow between the electrodes using the water as a conductor. Water is not a good conductor, like copper, but is conductive enough to be measured using appropriate electronic circuitry.

The Cleveland Range control is a two probe system having two metallic probes (LOW and HI) for sensing water in the generator; a COM terminal is placed on the tank. The LOW probe is placed so that it will come in contact with the water when the water level is just above the desired water level, enough to protect the heat source. If the water is of sufficient level and the LOW probe is in the water, a small electrical current provided by the level control electronics will flow between the probe and COM; this flow will be sensed by the electronics which in turn will activate the "HEAT" relay to apply AC power to the HEAT terminal on the control circuit board.

Similarly, the HI probe is located at the desired water level fill (above the LOW probe level) so that when the water level has reached the desired fill level elec trical current will flow between the El probe and COM. The action of this probe is reversed from the previous situation so that when water reaches the HI probe, the WATER fill relay is deactivated so that AC power to the WF is turned off. When the water level drops below the El probe, the WF terminal will be re-energized after a five second delay. The time delay is to prevent bubbling or turbulence in the generator from chattering to WATER fill relay or the water valve solenoid.

The control runs on 120 vac and is transformer isolated so that the probes and the electronics are run at low voltage and are not common to the AC power line.

Note that in many Cleveland Range generators both sensing probes are inserted from the front top of the unit down into the generator. In this case, the LOW probe will be the longest and the HI probe will be the shortest.
