CLEVELAND RANGE GEMINI 24CGA 6.2 AND 24CGA10.2
SEQUENCE OF OPERATIONSMechanical Timer
Starting with the timed manual switch in the timed position, and no time on the timer.1. To turn the unit on, turn the ON/OFF lever clockwise to the ON position
• This mechanically closes the drain.• The red “Power On” indicator is energized.• 115 VAC is sent through the timer to the three-second timer, which activates the
buzzer for three seconds.• 115 VAC is sent through the normally closed R1 contacts to the fan motor, turning it
ON• 115 VAC is sent to H and N of the water level board
2. With the water level board energized and no water in the generator • 115 VAC is sent from the FILL terminal to the fill solenoid.• The fill solenoid opens and the generator fills.
3. The water fills to the low probe shorting it to ground• 115 VAC is sent from the HEAT terminal to the timed manual switch. • 115 VAC is sent through the high limit to the primary of the 24VAC transformer.• The water continues to fill until the water level reaches the high probe then 115 VAC is
removed from the FILL terminal and the fill solenoid is turned off
4. 24VAC is sent to the ignition module.• Spark is sent to the igniter.• 24VAC is sent to the pilot coil of the gas valve and the coil of the R1 relay.
• The normally closed R1 contacts open, turning off the fan• The pilot lights, which acts as a standby heater. When the pilot is ignited and the
module detects 1.0 micro amps DC, the MV terminal on the module is energized itremains in this standby heat mode until a cooking compartment is turned “ON” (seestep 5).
5. When the timed/manual switch is in the timed position and time is on the timer or the timedmanual switch is set to the manual position:• 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.
• 115 VAC is sent from the compartment timer through the door switch to the normallyclosed contacts of the compartment thermostat and R2 relay coil.• The “Sure Cook” light is energized.
• 115 VAC is also sent from the door switch through the now closed contacts of the R1relay to the fan motor.
• The fan motor turns ON, and comes up to speed.
• The fan prover switch makes allowing 24 VAC to the normally open R2 contacts.• The normally open R2 contacts close and 24 VAC is sent to the main coil of the gas
valve.• The main burner is ignited and the water heated to steam.
• Steam enters the cabinet and the compartment thermostat closes at 193 degrees.• The “Sure Cook” light is de-energized.• If in the timed mode, 115 VAC is sent to the timer motor and the timer begins
counting down.• The condensate solenoid is energized sending cold water down condensate spray
nozzle pulling the steam around the product and down the drain.
6. When the timer times out or the unit is switched to the timed mode (with no time on thetimer) from the manual mode, 115 VAC is sent to the 3 second timer and then to the buzzerfor 3 seconds.
7. Whenever the water level drops below the high probe for 5 seconds 115 VAC is sent to theFILL terminal again.
8. When the on/off lever is turned off :• The drain is mechanically opened, and the generator begins to drain.• The red “Power On” indicator light is de-energized.• 115 VAC is sent to the 3-minute timer and the fill solenoid is energized for 3 minutes
flushing the drain.

Descaling Procedure-SteamCraft Ultra and Gemini Series
1. Turn the unit OFF and open thedoors:
This will drain and rinse the generator for about3 minutes.
2. Turn the unit power back On:The generator will begin to refill with water.
3. Select Timed with the Timed/Manualswitch:
DO NOT start the timer, since you do not wantto heat the water during descaling. Leave thedoors open.
4. Remove descaling port cap and addwith the specified amount ofDISSLOVE: (See chart above)
Do this while the unit is refilling. The generatorscan take-up to 8 minutes to refill.
5. After refill has stopped, add extra tapwater into the descaling port untilliquid is seen entering the cookingcabinet. Note: Ultra 10 gas will have liquidcoming out of the drain,
Adding extra water when descaling will raise thedescaling solution higher than the normal fill level,allowing the DISSOLVE to work on sensors andsurfaces above the water line
6. Let the descaler soak in generator forapproximately one hour:
7. After one hour, turn the unit powerOff: This will drain and rinse the generatorfor about 3 minutes.
8. After the 3-minute drain cyclecompletes, turn the unit back ON. Afterthe filling has stopped, add water untilliquid enters the cooking compartment (ordrain for the ultra 10 gas), and then turnthe unit OFF. This will drain and flush anyresidue from the water level controlassembly. Replace descaling cap.
9. After the 3 minute drain cyclecompletes, Turn the unit ON and setthe Timer for 20 minutes: Make sure theTime/Manual switch is in the timed settingand the doors are closed.
10. When the timer times out (after 20minutes) turn the power Off:This will drain and rinse the generator forabout 3 minutes.
This ends the descaling procedure. You cannow turn the unit back on and resume normalstartup and cooking operations.
How Much DISSOLVE to UseModel DissolveUltra 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.)
Note: Some SteamCraft Ultra models (theelectric powered Ultra 10 and Gemini 6 and 10,for example) have two generators and twodescaling ports. Both units should be descaledat the same time, using this procedure
