3 CLEVELAND RANGE CET8 SEQUENCE OF OPERATIONS Mechanical Timer. Supply power is sent to the primary of the main transformer. 5 VAC is sent from the secondary of the main transformer to the on/off rocker,. To turn the unit on, depress the red on/off rocker switch. 5 VAC is sent to the red power light. 5 VAC is sent to normally open drain valve closing it. 5 VAC is sent to H and N on the water level board. With the water level board energized and no water in the generator 5 seconds later 5 VAC is sent from the FILL terminal to the fill solenoid. The fill solenoid opens and the generator fills through the drain valve. The water fills to the low probe shorting it to ground 5 VAC is sent to the heat standby timer which will energize seconds every 4 minutes to maintain heat while unit is idle 5 VAC is sent from the HEAT terminal to the timed manual switch. 4. When the timed/manual switch is in the timed position and time is on the timer 5 VAC is sent from the timer to the R relay coil R relay energizes closing the RA and RB contacts 5VAC is sent through the now closed RB contacts to the timer motor 5 VAC is sent through the now closed RA contacts through the door switch to the normally closed contacts of the high limit switch. 5 VAC is then sent through the high limit to the coil of condensate solenoid The condensate solenoid opens spraying cold water down the compartment drain. 5 VAC is also sent through the high limit to the coil of the contactor. 5 VAC is sent to the clean light timer. When the clean light timer times down 5 VAC is sent to the clean light switch. When the clean light switch is depressed the clean light timer is reset. 5. When the contactor coil is energized supply voltage is sent to both of the elements. The elements are energized and the water is heated to steam. Steam is directed to the cooking compartment. 6. When the timer times out 5 VAC is sent to the second timer and then to the buzzer for seconds. 5 VAC is removed from the R relay. RA contacts open de energizing the heat circuit RB relay contacts open removing the 5 VAC from the timer motor

4 7. When the water level reaches the high probe then 5 VAC is removed from the FILL terminal and the fill solenoid is turned off. 8. After the water level drops below the high probe for 5 seconds 5 VAC is sent to the FILL terminal again. 9. The red on/off switch is depressed and the unit is turned off. 5 VAC is removed from the heat and timer circuit. 5 VAC is removed from the normally open drain valve allowing the steamer to drain. 5 VAC is sent to the -minute timer and the fill solenoid is energized for minutes flushing the drain.

23 Descaling Procedure-SteamCraft Ultra and Gemini Series How Much DISSOLVE to Use Model Dissolve Ultra / Gallon Ultra 5 Gallon Ultra 0 (Elec.) Gallon (ea.) Ultra 0 (Gas) ½ Gallon Gemini 6 & 0 Gallon (ea.) 6. Let the descaler soak in generator for approximately one hour: 7. After one hour, turn the unit power Off: This will drain and rinse the generator for about minutes.. Turn the unit OFF and open the doors: This will drain and rinse the generator for about minutes.. Turn the unit power back On: The generator will begin to refill with water.. Select Timed with the Timed/Manual switch: DO T start the timer, since you do not want to heat the water during descaling. Leave the doors open. 4. Remove descaling port cap and add with the specified amount of DISSLOVE: (See chart above) Do this while the unit is refilling. The generators can take-up to 8 minutes to refill. 5. After refill has stopped, add extra tap water into the descaling port until liquid is seen entering the cooking cabinet. te: Ultra 0 gas will have liquid coming out of the drain, Adding extra water when descaling will raise the descaling solution higher than the normal fill level, allowing the DISSOLVE to work on sensors and surfaces above the water line te: Some SteamCraft Ultra models (the electric powered Ultra 0 and Gemini 6 and 0, for example) have two generators and two descaling ports. Both units should be descaled at the same time, using this procedure 8. After the -minute drain cycle completes, turn the unit back ON. After the filling has stopped, add water until liquid enters the cooking compartment (or drain for the ultra 0 gas), and then turn the unit OFF. This will drain and flush any residue from the water level control assembly. Replace descaling cap. 9. After the minute drain cycle completes, Turn the unit ON and set the Timer for 0 minutes: Make sure the Time/Manual switch is in the timed setting and the doors are closed. 0. When the timer times out (after 0 minutes) turn the power Off: This will drain and rinse the generator for about minutes. This ends the descaling procedure. You can now turn the unit back on and resume normal startup and cooking operations.
