CLEVELAND RANGE GEMINI 24CGA 6.2
AND 24CGA10.2
SEQUENCE OF OPERATIONS
Mechanical 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 it
remains in this standby heat mode until a cooking compartment is turned “ON” (see
step 5).
5. When the timed/manual switch is in the timed position and time is on the timer or the timed
manual 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 normally
closed 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 R1
relay 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 the
timer) from the manual mode, 115 VAC is sent to the 3 second timer and then to the buzzer
for 3 seconds.
7. Whenever the water level drops below the high probe for 5 seconds 115 VAC is sent to the
FILL 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
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. Note: 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
Note: 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.
