CAUTION

Page 16

WARNING

When working with cleaning agents, nozzle rinsing fluid and spray bottles: Wear suitable clothing, protective gloves and protective goggles to help protect from splashes and spills. Failure to do so can result in chemical burns on skin and in eyes.

3. Manual Cleaning of the Oven Chamber

Read, understand, and heed and obey all instructions and safety information found on cleaning agent labels, Material Safety Data Sheets, and related documents and sources. Failure to do so can result in death, injury, and equipment damage.

a. Clean the Combi daily to prevent discoloration and corrosion of the stainless steel.

1) Avoid scratching the oven chamber or engaging frame.

2) Scratches can collect soil and / or allow corrosion to begin.

3) Do NOT use harsh or abrasive cleaning agents, scouring pads, or scrapers.

b. Clean the fan guard and the fan area behind the fan guard at the same time.

1) Release the quick-action locks on the oven racks and fan guard.

2) Pivot the oven racks and fan guard out into the oven chamber.

3) After cleaning, push the oven racks and fan guard closed and fix them in place with the quick-action locks.

WARNING

CAUTION

Do NOT use U-Shaped racks that are bent or otherwise damaged in any

way. Pans and accessories placed in damaged racks can tip and spill,

causing burns, injuries and/or equipment damage

4) Make sure that the U-Shaped racks do not become bent; otherwise grills, racks, containers and accessories will no longer be safely supported. If U-Shaped racks become bent then remove the Combi from service and contact your qualified Cleveland Range authorized service representative at once.

c. Clean the interior of the of the double glass doors daily.

1) Release the quick-action locks on the door glass.

2) Clean the glass with a non-abrasive cleaner and a soft cloth.

3) Do not use harsh or abrasive cleaning agents, scouring pads, or scrapers because they will damage the glass.

d. Regular cleaning of the hygienic plug-in gasket (door gasket) increases service life.

1) Wait for the gasket to cool.

2) Clean the gasket with mild, scent free dish detergent and a soft cloth.

3) Do not use harsh or abrasive agents, scouring pads or scrapers because they will damage the gasket.

4) Air dry the gasket.

B. Semi-Automatic Cleaning of the Oven Chamber

NOTE: Do NOT press the Start/Stop key while using the Semi-automatic Cleaning process. This stops the cleaning process.

WARNING

The Semi-Automatic Cleaning process is designed to be started when the oven chamber temperature is at or below 158°F. Death, injury, and equipment damage can result from starting the Semi-Automatic Cleaning process when the oven chamber is above 158°F.

1. Before starting the Semi-Automatic Cleaning process, make sure the oven chamber is below 158°F by stopping all processes and pressing the Temperature key twice to view the actual temperature.

a. If the oven chamber is above 158°F then open the Combi door and wait 15 minutes. b. Check the oven temperature again.

1) If the oven temperature is at or below 158°F then go to Step 2.

2) If the oven temperature is still above 158°F then wait 15 more minutes and check the oven chamber temperature. Repeat this step as needed until the oven chamber temperature is at or below 158°F and then go to Step 2.

2. See separate instruction sheet P/N 260AYM, “One-Hand Sprayer with Telescoping Wand,” for safety information, detailed instructions for using the sprayer, P/N 111598, and other information.

UInformation:

The unit’s electronic control board offers the possibility of calling up various internal program parameters and operating states in order to detect possible faults.

UAttention:

Any changes on the parameters in the Service program, other than the normal work adjustments (default values), could cause operation malfunctions.

UInstructions: Calling up Customer Service programU

1. Switch unit on with the ON/OFF key.

2. Press Service program key 1 on the back side of the control module 2.

3. The display now shows the service number and the affiliated service value and a short explanation. The service number is selected on the display; this means that it is shown inverse.

4. By turning the selector dial, various service numbers can be called up.

5. With the Scroll key, the service number and the service value can be alternately shown (only with control and diagnostic values).

6. If the service value is selected (inverse), it can be adjusted with the selector dial. The changed service value is saved by the controls when the service number springs back via the Scroll left key.

7. The included service list gives comprehensive information about the meanings of the service numbers, the maximum and minimum adjustable values, the default values (standard setting) as well as the corresponding specifics.

8. Press the Service program key 1 or the START/STOP key in order to leave Customer Service.

UAdvice:

The first letter of the service numbers indicates the following:

 r-- = read value  only for reading

 c-- = control value  for reading and writing (functions parameter)

 d-- = diagnostic value  for detecting errors and checking functions

Testing the outputs

Information: The electronic controls offer the possibility via the service numbers d04 - d24 to activate various outputs

and various functions. Thereby checking the outputs and detecting any defects.

Safety: When specific actuators (processes) are often tripped, one after the other, they can be

destroyed!!!
