Cleveland Range equipment is designed and built to comply with applicable standards for manufacturers. Included among those certification agencies which have approved the safety of the equipment design and construction are: UL, A.G.A., NSF, ASME, CSA, CGA, and others.

Cleveland Range equipment is designed and certified for safe operation only when permanently installed in accordance with local and/or national codes. Many local codes exist, and it is the responsibility of the owner and installer to comply with these codes.

In no event shall Cleveland Range assume any liability for consequential damage or injury resulting from installations which are not in strict compliance with our installation instructions. Specifically, Cleveland Range will not assume any liability for damage or injury resulting from improper installation of equipment, including, but not limited to, temporary or mobile installations.

INSTALLATION INSTRUCTIONS FOR ALL MODELS

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."

WARNING

The flooring that will be directly under the boiler, must also be made of a noncombustible material.

1. 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 free and clear of combustibles. Dimensions and clearance specifications are shown on the specification sheet.
2. 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.
3. The drain line outlet discharges exhaust steam and hot condensate. Connect 1½" IPS piping (or larger) to extend the drain line to a nearby open floor drain. Up to two elbows and six feet of 1½" 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" 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 drain 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 in 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.

FAILURE TO OBSERVE THESE REQUIREMENTS CAN RESULT IN DAMAGE TO EQUIPMENT AND/OR THE POSSIBILITY OF INJURY.

(Continued on next page)

- 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 fill 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.

1. Connect COLD water supply plumbing to the line strainer. (Never connect hot water to the boiler's water fill line strainer). Constant flow pressure must be 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 to reduce the water pressure to less than 60 psi. Locations and pressure data are shown on the specification sheet. 14 " 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 38 " IPS. Flush water supply lines thoroughly before connecting them to the unit. Use water which is low in total 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 fill swing spout, 38 " (10mm) hot and/or cold water connection(s) will be required at the swing spout's valve.

1. Turn on the cold water supply to the unit. Ensure that the manual water valve, inside the base cabinet, is open.

2. Connect the primary fuel supply in accordance with the following instructions. Location and other data are shown on the specification sheet.

For Gas-Fired Steam Generators:

Post, in a prominent location, instructions to be followed in the event the user smells gas. This information shall be obtained by consulting the local gas supplier. Install a sediment trap (drip leg) in the gas supply line, then connect gas supply piping to the boiler's gas valve piping. GAS-FIRED EQUIPMENT IS DESIGNED FOR INSTALLATION ONLY IN NON-COMBUSTIBLE LOCATIONS. THIS INCLUDES THE FLOORING THAT WILL BE DIRECTLY UNDER THE EQUIPMENT. Location, plumbing size, and pressure data are shown on the specification sheet. Boilers rated at less than 225,000 BTU require 3/4'' IPS gas supply piping, and boilers rated at 225,000 BTU or more require 1'' IPS gas supply piping. Natural gas supply pressure must be between 4'' - 14'' water column, and L.P. gas supply pressure must be between 12'' - 14'' water column. NEVER EXCEED 14'' WATER COLUMN ( 1/2 psi) GAS PRESSURE. If the gas supply pressure exceeds 14'' water column, a pressure regulating valve must be installed in the gas supply plumbing to reduce the gas pressure to less than 14'' water column. Installation must be in accordance with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1-1984. Installation in Canada must be in accordance with Installation Codes for Gas Burning Appliances and Equipment B149.1 and B149.2. Use a gas pipe joint compound which is resistant to LP gas. Turn the gas valve's control knob to "on" (the word "on" on the knob will be opposite the index on the valve's body). Test all pipe joints for leaks with soap and water solution. Never obstruct the flow of combustion and ventilation air. Observe all clearance requirements to provide adequate air openings into the combustion chamber. The appliance and its individual shut-off 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 psi ( 14'' water column or 3.45 kPa). The appliance must be isolated from the gas supply piping system at test pressures equal to or less than 1/2 psi ( 14'' water column or 3.45 kPa). A permanent 115 volt electrical connection is required at the junction box. The junction box location is shown on the specification sheet. The unit must be electrically grounded by the installer.

For Electric-Powered Steam Generators:

Connect electric power: location and data are shown on the specification sheet. Provide connection as required by your unit; either directly to the single contactor, or to the terminal block (when equipped with multiple contactors). Electric supply must match power requirements specified on the data plate inside the base cabinet. The copper wiring must be adequate to carry the required current at the rated voltage. A separate fused disconnect switch must be supplied and installed. The unit must be electrically grounded by the installer.

For Steam Coil Steam Generators:

Connect steam supply piping to the input side of the steam coil. Location and pressure data are shown on the specification sheet. Incoming steam pressure must be regulated between 35 and 45 psi. A 34'' strainer, equipped with a 20 mesh stainless steel screen, must be supplied and installed at the incoming steam connection point. Flush the steam line thoroughly before connecting it to the boiler. To ensure an adequate volume of steam, the branch steam supply line must be 34'' IPS minimum. Connect the inverted bucket trap to the outlet end of the steam coil. Fill the trap with water before installing it. A permanent 115 volt electrical connection is required at the junction box. The junction box location is shown on the specification sheet. The unit must be electrically grounded by the installer.

For Direct-Steam-Connected Steamers/Kettles:

Connect steam supply piping to the input side of the line strainer. Location and pressure data are shown on the specification sheet. Flush the steam line thoroughly before connecting it to the steamer. To ensure an adequate volume of steam, the branch steam supply line must be 34'' IPS minimum. (Direct-steam-connected kettles require 12'' IPS pipe if the kettle's total capacity is 20 gallons or less, and 34'' IPS pipe if the total capacity exceeds 20 gallons.) A permanent 115 volt electrical connection is required at the junction box. The junction box location is shown on the specification sheet. The unit must be electrically grounded by the installer. (Note: pressure steamers equipped with strictly manual steam and drain valves do not require an electrical connection.)

(Continued on reverse side)

(Continued)

1. Press the top of the power on-off rocker switch. The red indicator light in the switch will come on and the boiler will begin to fill with water.
2. Direct-steam-connected steamers are not equipped with self-generating boilers or "steam" switches. Therefore, these models do not require the 5-minute boiler water fill time, nor is it necessary to push a "steam" switch to produce steam, as indicated in step #9. As soon as the pressure gauge on the control panel registers 10 psi (5 psi for pressure steamers), preheating may begin. If you are operating a direct-steam-connected steamer, steps #9 and #10 do not apply. Refer directly to step #11.
3. After about five minutes, the amber light in the "steam" switch will glow, indicating the water has reached a safe operating level in the boiler. The "steam" switch can now be pressed (momentarily) in order to produce steam in the boiler. This will activate the energy source (electric heaters, gas burners, or steam solenoid valve), and the amber light will go out. The energy source cannot be activated until the boiler contains sufficient water, indicated by the amber light. The "steam" switch must be pushed to re-start the steamer after it is shut off for any reason (including a momentary power interruption). Do not attempt to start or operate this appliance during a power failure. Whenever the amber light is illuminated, the heater, steam supply, or burners are off, and no steam is being generated. (Note: for units containing gas-fired boilers only: if the burners fail to ignite in four seconds, a safety circuit will de-energize the system.: In this event, momentarily press the power switch to the "off" position, then back to the "on" position. The "steam" switch amber light should be on. Wait 5 minutes, then press the "steam" switch to start the burner ignition cycle once again.)
4. Check to ensure that the water in the boiler's sight gauge glass automatically stays about 13 full when the boiler is started up and operated.
5. Check to ensure that the steam pressure gauge registers 10 psi (5 psi for pressure steamers).
   The steam pressure is factory-adjusted to provide the proper pressure. In some cases, however, the factory setting may shift due to shaking in transit, and resetting will be required after installation. Proper adjustments and maintenance procedures are detailed on a separate data sheet entitled "Steam Pressure Adjustments." Adjustments should be made only by qualified service personnel. The factory pressure settings shown in the accompanying chart should never be exceeded.
6. When the installation is complete and free of leaks, refer to the Operating Procedures page, in order to check for proper operation of the unit.

INSTALLATION INSTRUCTIONS FOR DIRECT STEAM KETTLES

WARNING: Installation of kettle must be accomplished by qualified installation personnel, working to all applicable local and national codes. Improper installation of product could cause injury or damage.

This equipment is built to comply with applicable standards for manufacturers. Included among those approval agencies are: UL, NSF, ASME/NtL.Bd., CSA, ETL, and others. Many local codes exist, and it is the responsibility of the owner and installer to comply with these codes.

INSPECTION

Before unpacking visually inspect the unit for evidence of damage during shipping. If damage is noticed, do not unpack the unit, follow shipping damage instructions.

SHIPPING DAMAGE INSTRUCTIONS

If shipping damage to the unit is discovered or suspected, observe the following guidelines in preparing a shipping damage claim.

1. Write down a description of the damage or the reason for suspecting damage as soon as it is discovered. This will help in filling out the claim forms later.

2. As soon as damage is discovered or suspected, notify the carrier that delivered the shipment.

3. Arrange for the carrier's representative to examine the damage.

4. Fill out all carrier claims forms and have the examining carrier sign and date each form.

INSTALLATION

The first installation step is to refer to the specification sheet for clearance requirements, in order to determine the location of the kettle. Next, carefully cut open the shipping carton for easy removal of the kettle.

ASSEMBLY

KDT-T SERIES (Table-Top Models)

Table-top models must be positioned on a firm stand or existing counter top, and secured in place. An optional modular cabinet base, with level-adjustable legs, is available. Make two 3/4" holes, for the kettle legs, in a cabinet or countertop. Remove the leg mounting locknuts from the kettle's legs and install the legs into the two 3/4" holes. Secure the kettle to its base by refastening the locknuts from underneath the cabinet or countertop. Place a carpenter's level on the kettle rim and level the cabinet. Once the kettle is secure, screw the tilt handle into the mounting block welded to the side of the kettle.

INSTALLATION

OF SERVICE CONNECTIONS

Install service connections as required. Locations and other data are shown on the specification sheet.

STEAM

All steam plumbing to and from the kettle and steam boiler should be thoroughly cleaned and inspected for dirt and debris before final connections to the kettle are made.

Refer to the specification sheet for the minimum allowable size of the branch steam supply plumbing (from the steam "main" plumbing or a nearby boiler). Generally, kettles require 1/2" i.p.s. pipe. Kettles require 5-50 psi steam pressure. If the steam supply pressure exceeds 50 psi, a pressure reducing valve is required. The steam inlet is at the right side of the kettle, as seen from the front.

(Note: Table-top kettles are available, through special order ONLY, with the steam supply valve on the left side of the kettle. In this rare instance, the steam inlet would be on the left side of the kettle, as seen from the front. The steam condensate trap would then be on the right side.)

CONDENSATE

The steam condensate trap must be plumbed to a drain, using minimum 1/2" NPT plumbing. The condensate line is limited to a maximum rise of 10 feet in order for the steam pressure to adequately force the condensate through the plumbing. Any higher rise requires a pump.

If the steam boiler to which this kettle is installed has a condensate return, a 1/2" (13mm) steam strainer, a 1/2" (13mm) steam trap, and a 1/2" (13mm) check valve must be installed on the output (condensate) side of the kettle.

WATER

The water faucet, with swing spout, requires 1/2 inch O.D. copper tube plumbing for hot/or cold water supplies to the faucet (if so equipped).

FINAL INSTALLATION CHECK

1. Partially fill the kettle with water.
2. Slowly turn the steam supply valve's knob to the open position.
3. Release the safety valve, ensuring that the steam escapes freely. Stay clear of steam exhaust when releasing the safety valve.
4. Observe that the water in the kettle comes to a boil.
5. Close the steam supply valve.
6. Drain off the water by tilting the kettle.

OPERATION

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

Turn the steam control valve to the full open position by turning the knob counterclockwise, then allow the kettle to preheat.

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 heating is begun.

Fill kettle with product to desired level.

When the product 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, close the steam control valve by turning the knob.

For kettle/steamer combinations: If the boiler 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 part of kettle cleaning is to prevent foods from drying on. For this reason, cleaning should be completed immediately after cooked foods are 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 soil inside the 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 mild soapy water and a damp sponge, wash the exterior of the kettle, rinse, and dry.

NOTE: For more difficult cleaning applications, one of the 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.

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. If the generator's feedwater contains more than 300 parts per million of total dissolved solids, the generator must have a blowdown after each 4-6 hours of use. "Blowdown" means the generator must be drained under pressure.

THE GENERATOR "BLOWDOWN" IS PERFORMED BY SHUTTING OFF THE UNIT'S 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: Neven 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. Overtightening 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 minimum treatment required in most areas is water softening, although local water conditions may require more intensive 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

TOTAL ALKALINITY

SILICA

pH FACTOR

less than

less than

less than

greater than

60 parts per million

27 parts per million

13 parts per million

7.5

Consult the state department of water or a local water treatment specialist 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.

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 pre-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 2-PROBE TYPE STEAM GENERATORS

WARNING: Steam under pressure may cause serious injury and bodily harm when it is accidentally or carelessly released. Improper handling 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 carefully. 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 footpounds torque. Overtightening may cause uneven stress, which may result in the weakening and possible breakage of the plate.

Descaling Procedure for Two-Probe Steam Generators

The steam generator should be descaled at least once a month, depending on scale buildup. If you have serious steam generator scale buildup, install a water treatment system for the steamer. Cleveland Range recommends use of the descaling kit, part number 40891, which consists of powdered sulfamic acid. Full descaling may take several hours, or more than one acid process. Perform descaling until all scale buildup is cleaned out.

Follow hazard and leak cleanup procedures on acid container label. If the label is not readable or has been removed, refer to the following hazard and emergency instructions as a minimum safety precaution.

THESE INSTRUCTIONS ARE FOR USE WITH POWDERED SULFAMIC ACID ONLY.

- Health Hazard Data, Effects of Overexposure - Product is extremely irritating to the eyes and may result in eye burns. Product is severely irritating to skin and can result in skin burns; repeated or prolonged contact with more dilute solutions may result in dermatitis. Aerosol mist or vapors are irritating to respiratory tract, eyes and throat. Prolonged exposure to high concentration may result in pulmonary edema. If ingested, may result in abdominal hemorrhage with severe abdominal pain, nausea, vomiting or loss of consciousness; necrosis of stomach and gastrointestinal tract may also occur.

- Emergency and First Aid Procedures - In case of eye contact, immediately flush eyes with plenty of water for at least 15 minutes. Seek medical aid. In case of skin contact immediately wash with soap and plenty of water for at least 15 minutes while removing contaminated clothing. Seek medical aid. If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Seek medical aid. If swallowed, do not induce vomiting. Give large quantities of water. Seek medical aid. Never give anything by mouth to an unconscious person.

- Spill or Leak Procedures - Contain spill. Cover the contaminated surface with sodium bicarbonate or a soda ash-slaked lime mixture

(50-50). Mix and add water if necessary to form slurry. Scoop up slurry and wash residue down drain with excess water. Wash site with soda ash solution.

WARNING

The powdered sulfamic acid in descaling kit 40891 can be harmful if not handled properly. Follow these basic safety rules for handling and using acid.

Wear protective clothing when mixing or applying chemical cleaners. Wear rubber gloves, mask and approved cup-type goggles.

Avoid breathing fumes. If acid comes in contact with skin, flush immediately with large quantities of cold water. Remove contaminated clothing.

If chemical contacts eyes, flush with cold water for a minimum of 15 minutes. Get immediate medical attention.

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 heat 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 electrical current will flow between the HI 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 HI 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.

A) SYMPTOMS OF WATER LEVEL CONTROL RELATED PROBLEMS:

1) Boiler overfills or floods
2) Boiler dry fires (system underfills or doesn't fill)
3) Boiler doesn't fill at all
4) Water fill solenoid chatter
5) Heater contactor chatter
6) Fills but cuts out on LOW WATER before filling again
7) Overfills but does not heat
8) Fills but does not heat

B) POSSIBLE CAUSES:

1) Inoperative water level control circuit board (P/N 23198)
2) Incorrect or damaged wiring to probes
3) Incorrect or damaged wiring from water level board to loads
4) Damaged probes
5) Probes shorted together
6) Scale build-up on probes

C) FAULT ISOLATION PROCEDURE:

Equipment Required: Volt/Ohmmeter (VOM) or Multimeter

STEP	TEST	RESULT	REMEDY
1.	Is power applied to the control circuit board? Measure L1-L2 at the board to be 120 VAC ± 15V.	Yes	Go to Step #2
		No	Correct external supply problem
2.	Remove two AC power wires from control board and connect ohmmeter to control board power terminals. Is resistance between 100-1000 ohms?	Yes	Reconnect power and go to Step #3
		No	Replace control board P/N 23198 (inoperative transformer)
3.	Visually inspect probe wiring for damaged or broken wires or loose or missing terminals at either end. Is wiring visually OK?	Yes	Go to Step #4
		No	Replace wiring as required
4.	Are the following connections made correctly?	Yes	Go to Step #5
	A) COM input on board to boiler ground	No	Correct probe wiring as required (see Figure 1)
	B) LO input on board to long length "LO" probe
	C) HI input on board to short "HI" probe
5.	Temporarily disconnect the wire from the HTR terminal so that the heat source will not operate. Is the heat source off?	Yes	Go to Step #6
		No	Check heat source and wiring in cooker
6.	With HTR still disconnected, disconnect the LOW wire at the LOW terminal of the control board. Measure the AC line voltage between the HTR and L2 terminals on the control board. Is the voltage 0 vac? NOTE: Digital meters may read a few volts due to their high input impedance; this should be considered as 0 vac.	Yes	Go to Step #7
