40 CLEVELAND RANGE 24CEA10 SEQUENCE OF OPERATIONS Mechanical Timer 1. Supply power is sent to the primary of the main transformer. 115 VAC is sent from the secondary of the main transformer to the on/off rocker, 2. To turn the unit on, depress the red on/off rocker switch. 115 VAC is sent to the red indicator light. 115 VAC is sent to both coils of the normally open drain valves closing them. 115 VAC is sent to the H and N terminals of both water level boards. 3. With the water level board energized and no water in the generators After a 5 second delay, 115 VAC is sent from the FILL terminals to the fill solenoids. The fill solenoids open and the generators fill through the drain valves until the high probe is grounded (see step 4). The water fills to the low probe in each probe assembly shorting it to ground 115 VAC is sent from the HEAT terminals of the water level board to the timed manual switches. 115 VAC is sent to the heat standby timer which will energize the R2 relay coil 3 seconds every 4 minutes The normally open contacts of the R2 relay close bypassing the timed/manual switch to maintain heat while unit is idle 4. For each compartment, when the timed/manual switch is in the manual position or timed position with time on the timer 115 VAC is sent from the timer to the coil of the R5 relay for the top compartment The R5 relay energizes R5B contacts close sending 115 VAC to the motor timer R5A contacts close sending 115 VAC through the optional door switch to the normally closed contacts of the high limits 115 VAC is then sent through the high limits to the coil of condensate solenoid and the coil of the contactor. 115 VAC is sent to the clean light timer. When the clean light timer times down 115 VAC is sent to the clean light switch. When the clean light switch is depressed the timer is reset. When the contactor is energized supply voltage is sent to both of the elements. 115 VAC is sent from the timer to the coil of the R6 relay for the bottom compartment The R6 relay energizes R6B contacts close sending 115 VAC to the motor timer R6A contacts close sending 115 VAC through the optional door switch to the normally closed contacts of the high limits 115 VAC is then sent through the high limits to the coil of condensate solenoid and the coil of the contactor.

41 115 VAC is sent to the clean light timer. When the clean light timer times down 115 VAC is sent to the clean light switch. When the clean light switch is depressed the timer is reset. When the contactor is energized supply voltage is sent to both of the elements. When the mechanical timer times out 115 VAC is sent to the 3-second timer and then to the buzzer for 3 seconds. 5. When the water level reaches the high probe then 115 VAC is removed from the FILL terminal and the fill solenoid is turned off. 6. After the water level drops below the high probe for 5 seconds 115 VAC is sent to the FILL terminal again. 7. The red 115 VAC switch is depressed and the unit is turned off. 115 VAC is removed from the timer and heat circuits. 115 VAC is removed from the normally open drain valves allowing the steamer to drain. 115 VAC is sent to the 3-minute timer and the R1 relay coil is energized. The normally open contacts of the R1 relay will close The fill solenoids are then energized for 3 minutes flushing the drains.

55 Descaling Procedure-SteamCraft Ultra and Gemini Series How Much DISSOLVE to Use Model Dissolve Ultra 3 1/2 Gallon Ultra 5 1 Gallon Ultra 10 (Elec.) 1 Gallon (ea.) Ultra 10 (Gas) 1½ Gallon Gemini 6 & 10 1 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 3 minutes. 1. Turn the unit OFF and open the doors: This will drain and rinse the generator for about 3 minutes. 2. Turn the unit power back On: The generator will begin to refill with water. 3. Select Timed with the Timed/Manual switch: DO NOT 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 10 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 10 and Gemini 6 and 10, for example) have two generators and two descaling ports. Both units should be descaled at the same time, using this procedure 8. After the 3-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 10 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 3 minute drain cycle completes, Turn the unit ON and set the Timer for 20 minutes: Make sure the Time/Manual switch is in the timed setting and the doors are closed. 10. When the timer times out (after 20 minutes) turn the power Off: This will drain and rinse the generator for about 3 minutes. This ends the descaling procedure. You can now turn the unit back on and resume normal startup and cooking operations.
