INTRODUCTION

To get the full advantage of steam cooking, your Cleveland/ALCO equipment must be properly installed. A steamer which is improperly installed, improperly used, improperly maintained, or improperly repaired will create a dangerous condition and may cause injury to personnel.

Your Cleveland/ALCO equipment will require minimum servicing provided it is operated according to instructions and given the care recommended.

Make sure that responsible personnel understand how your steam cooking equipment should be operated and cared tor. Proper use and maintenance pay handsome dividends in long life and satisfactory performance.

Safe steam cooking equipment operation dictates that every owner of steam cooking equipment should follow these rules tor operational safety:

1) Begin a comprehensive, continuous program of internal and external steam cooking equipment inspection.

2) Never allow untrained personnel to operate or experiment with a steamer.

3) At the end of each day's operation —

— Remove any spilled food, then wash the racks and compartment interiors thoroughly with mild detergent in warm

water.

— Rinse thoroughly with dean warm water.

— Let rinse water drain through compartment drain opening. If water does not drain freely, drain lines must be

cleaned out before cooking again. Clogged or slow drains are dangerous because hot water may spill out when compartment doors are opened after a cooking cycle.

— When cleaning the steamer's exterior, never apply water to controls on the console. Use a damp clot h for

cleaning.

4) Always leave the compartment door ajar when the compartment is not in use.

5) Shut the unit down at the end of each day's operation as follows — — On boiler-equipped steamers, blow down the boiler. For specific information, refer to "Steam Generators •

Maintenance Procedures."

— On direct-connected steamers, cut off the main steam supply with a valve ahead of the steamer's pressure

reducing valve.

— On SteamCraft II models, (one compartment counter-top model) depress the power switch to the "off"

position.

6) Read and follow The Cleveland/ALCO instructions on steamer and steam generator maintenance and servicing

in the Owners Manual before making any adjustments or replacement of pans, or decision to buy parts, or before calling tor serv ice.

7) Use only replacement parts which are factory authorized as equivalent to the parts being replaced, to preserve

the certification of Underwriters Laboratories, American Gas Association, Canadian Standards Association or Canadian Gas Association (as applicable).

8) Never allow unqualified personnel to tamper with the steamer or steam generator controls, or to replace worn-

out parts

9) For gas-fired steam generators (boilers): 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.

Stand Pipe: A vertical pipe holding a column of water, topped with a column of air. The air pocket provides a "shock absorber" effect, to reduce or eliminate the possibility of "water hammering" in the plumbing. Strainer Removes particles from the water supply which could result in damage to plumbing components.

Pressure Reducing Valve: Required if the incoming water pressure exceeds 60 psi.

Check Valve: Eliminates the possibility of steam generafor water backing up into the water supply plumbing. (This check valve may be required by local plumbing codes.)

WATER QUALITY REQUIREMENTS If the purity of the incoming water is good, the generafor, the heating element and the valves should give years of trouble free. efficient service with a minimum of servicing.

The recommended minimum water quality standards, whether untreated or pretreated, based upon 4 hours of operation before the steamer is shut off and allowed to drain, are as follows:

• TOTAL ALKALINITY less than 20 parts per million • pH FACFOR greater than 7.5

Consult a local water treatment specialist for an on-the-premises water analysis and for recommendations concerning steam generafor feed water treatment (if required), in order to remove or reduce harmful concentrations of minerals. The use of a poor quality (highly mineralized) water will mean that more frequent servicing of water sensitive components will be necessary. The fact that a water supply is potable is not proof enough that it will not be detrimental to the water sensitive components. The steamer should be shut off for 3 minutes every 4 hours, in order to minimize scale build-up.

DRAIN A 1" N.P.T. fitting is provided. The drain termination must be free venting. Up to two elbows and a maximum of six feet of I* IP.S. pipe may be attached to the termination. However, the piping must have a gravity flow and vent freely to the air. Each steamer requires its own 1" I.RS. drain extension. Do not interconnect any other drains to this steamer's drain extension.

If these instructions are nor complied with, there will be steam and water leakage past the compartment door.

INSTALLATION CHECK

Installer must check out the steamer per the following procedure.

CHECK OUT STEPS

1) Empty the cooking chamber of all literature and leave the door open.

2) Make sure the cold water supply line to the generafor is open.

3) Turn on the electrical service to the cooker at the fusible disconnect box.

4) Push the "water on" switch button to the right. The switch is illuminated when it is in the "ON" position.

5) Set the steam control at number ten. Steam should be visible inside the cooking chamber after five minutes of operation.

6) Let the steamer continue to operate for five additional minutes with the steam control set at ten. Steam flow should be visible for

this entire period of operation.

7) Set the steam control to number five. Steam will continue to flow but in a lesser amount.

8) To check the timer and buzzer, turn the timer past 10 minutes to wind it. Then reset the timer at three minutes. At the end of the three minutes, the buzzer will sound for three seconds and then stop.

9) To completely shut down the steamer, push the "water on" switch button to the left (the light should go out), and turn the steam control knob to zero. The steam generafor water will automatically drain out. At this time. the generafor flush cycle will be energized. This system automatically flushes the generafor and drain line to assist in removal of lime deposits. After 3 minutes, the flush cycle should end and the steamer should shut off completely.

If the cooker has functioned as described, it is ready for use. Installer: Please complete and mail the Insialler's Checklist.

OPERATION

Operation of the Cleveland Steamcraft II is very easy. Each operator should be familiar with the following procedures to effectively start operate, and shut down the steamer each day.

Start-up and Preheat

1 Push the "water on" switch to the right. The switch is illuminated when it is in the "on" position.

2 Turn the steam control knob to the number 10 setting. To monitor the start-up, leave the cooking compartment door open.

Steam should begin to appear inside the cooking compartment after approximately 5 minutes. Close the door and allow the steam flow to continue for 5 more minutes to preheat the compartment. To close the door, swing it shut with a quick. snapping motion.

3 The Steam Cooker is now ready for use. Either proceed with cooking, or turn the steam control knob to "stand-by" at the

number 1 setting.

WARNING:DO NOT PUT YOUR FACE OR HAND(S) INTO THE COOKING COMPARTMENT WHEN THE STEAMER IS IN OPERATION. STEAM CAN CAUSE SERIOUS BURNS AND BODILY HARM.

Cooking Operation:

1. Check the cooking compartment to ensure it is warm. If it is cool perform the steps for preheating.

2. Place the pan(s) of food into the cooking compartment by sliding the pan(s) into the two slide racks, and secure the door. Optimum steam heat transfer, and therefore a higher quality food product, is achieved when shallow, perforated, uncovered pans are used.

3 Activate the steam flow by setting the steam control knob at number 10. The steam supply is variable from 10% at the

number 1 setting, to 100% at the number 10 se tting, to supply the precise volume of steam required for cooking. defrosting, or preheating of fresh or frozen food. For cooking fresh or frozen food, set the steam control knob at number 10. To conserve energy when cooking only one pan of fresh food. set tings lower than number 10 may be successfully used, but the timer setting may have to be increased.

4. Turn the timer knob past 10 minutes to wind the timer spring, then set the timer at the cooking time required. A buzzer will sound for 3 seconds at the end of the selected time, then it will stop buzzing automatically.

5. Remove the food from the cooking compartment promptly or it will continue cooking. Steam flow is not shut off by the timer. Steam flow is only shut off when the steam control knob is set at zero.

6. After the cooking cycle is complete, set the steam control knob to "stand-by" at the number 1 setting to keep the compartment warm, in preparation for the next cooking cycle.

7 The door may be opened any time during the cooking cycle to inspect season, add, or remove food. but keep hands out of the cooking compartment to prevent burns. Frequent opening of the door may result in longer cooking times.

Short-Term Holding:

Some foods, after they have been prepared, can be returned to the cooking compartment to be kept hot for short periods of time (up to 45 minutes) with minimum product change, by turning the steam control knob to the number 1 setting.

Shutdown: The Steamcraft II must be shut off for three minutes every four hours to automatically drain highly mineralized water from

the steam generator. This is accomplished by pushing the lighted "water on" switch to the left. Turning the steam control knob to zero does not shut-off the steamer, and therefore does not drain the steam generator.

CARE AND CLEANING

Your Steamcraft II must be cleaned regularly to maintain its fast efficient cooking performance and to minimize down time.

1. The steam generator must be drained every four hours, as well as at the end of the day to remove harmful highly mineralized

water. When steam is produced, the water in the generator is being distilled. During this process, the dissolved minerals that come into the generator with the water remain in the generator as the water boiIs away as steam. When allowed to accumulate, the water becomes highly mineralized, which will result in erratic operation, slower cooking times, accelerated corrosion of the heater element, and ultimately, heater element failure. When the steamer is shut off, an automatic 3 minute water purge cy cle will flush the scale out of the steam generator. Remember, turning the steam control knob to zero only shuts off the steam supply. The steamer is shut off, and the generator is automatically drained and cleaned, only when the lighted "water on" switch is pushed to the left.

• With the steamer off, open the cooking compartment door and allow the steamer to cool before cleaning the cooking compartment and its components.

2. The steamer is equipped with a drain screen in the back of the cooking compartment. The steamer should never be operated without the screen in place. This screen prevents large food particles from entering and possibly restricting the drain line. Any restriction of the drain line may cause a slight build-up of back 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 necessary for optimum performance. Pouring USDA approved drain cleaner through the compartment drain once a week will help to ensure an open drain.

3. At the end of each day's operation, remove any spilled food from the steamer, then wash the pan slide racks, drain screen, door gasket, and compartment interior with mild detergent and warm water. 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. The pan slide racks are easily removed from the cooking compartment for thorough cleaning, and they are stainless st eel, so they can be washed safely in a mechanical dishwasher.

5. Always leave the compartment door ajar when not in use, to extend gasket life and to prevent the gasket from adhering to the steamer. Unnecessary compression of the gasket shortens its life.

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.

7. Once every three months, shut off the cold water supply to the steamer, and clean the water line strainer.

MAINTENANCE

Your Steamcraft II is equipped with an automatic 3 minute water purge system which will flush the highly mineralized water out of the steam generator when the steamer is shut off. If the steamer's feedwater supply is of average hardness and mineral content (less than 200 parts per million of total dissolved solids), and the steamer is shut off for three minutes every 4 hours, this purge system should provide a maintenance free steam generator. However, if your water contains more than 200 parts per million of total dissolved solids, additional maintenance may be required. In this case. your steamer should be shut off every 2 or 3 hours, depending upon the mineral content of the water. In addition, it may be necessary to periodically have a service technician remove the steam generator's side panel and clean the scale accumulations on the inside.

The Cleveland Range Company supports a worldwide network of Maintenance and Repair Centers, which are regional distributors of parts and service. Contact your nearest Maintenance and Repair Center for the name of an authorized service agency in your area, or for replacement parts, or information regarding the proper maintenance and repair of your equipment. In order to preserve the various agency safety certifications (UL. A.G.A, CSA, CGA. NSF, ASME/Ntl. Bd, etc.), only factory supplied replacement parts should be used. The use of other than factory -supplied replacement parts will void the warranty.

INSTALLATION CHECK Proper operation of the Cleveland Steamcraft II is dependent upon proper installation. After the steamer has been installed, a few quick checks could save unnecessary service calls.

1. The Steamcraft II requires a cold water connection at the rear of the steamer for proper efficient operation. DO NOT USE HOT WATER. The cold water feed line should maintain 35 to 60 psi flow pressure, and not experience a pressure drop when other appliances are used. Pressure in excess of 60 psi must be reduced (with a pressure reducing valve) to 35 to 60 psi.

2. The steamer must be level.

3. The supply voltage must agree with the voltage indicated on the rating label on the back of the steamer, and the voltage shown on the packing slip. The steamer must be protected with a separate fused disconnect and be property grounded, in accordance with the national electric code.

4. The termination of the drain extension must vent freely to the air (not plumbed solidly into the floor drain). It must have a gravity flow, be 1" diameter minimum (IPS) and not exceed 6' in length, with no more than two elbows, before draining. Each steamer requires its own 1" IPS drain extension. Do not interconnect any other drains to this steamer's drain extension.

CAUTION: IF THESE INSTRUCTIONS ARE NOT COMPLIED WITH. THERE WILL BE STEAM AND WATER LEAKAGE PAST THE COMPARTMENT DOOR GASKET.
