CLEVELAND RANGE 21CET16
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,
1. 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 the normally open drain valve closing it.
•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
•After a 5 second delay, 115 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
•115 VAC is sent from the HEAT terminal to the timed manual switch.
•115 VAC is sent to the preheat thermostat.
•115 VAC is then sent through the high limits to the coil of condensate solenoid.
•The condensate solenoid opens sending cold water down the compartment
drain.
•115 VAC is also sent through the high limits to the coil of the contactor.
•When the contactor is energized supply voltage is sent to both of the elements.
•The heat circuit will stay energized until the preheat thermostat opens at 185
degrees.
3. When the timed/manual switch is in the timed position and time is on the timer
•115 VAC is sent from the timer to the coil of the R2 relay
•The R2 relay energizes
•R2B contacts close and 115 VAC is sent to the motor of the timer
•R2A contacts close and 115 VAC is through the optional door switch to the normally
closed contacts of the high limits
•115 VAC is then sent through the high limit to the coil of condensate solenoid and the
coil of the mercury 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 clean light timer is reset.
4. When the contactor is energized supply voltage is sent to both of the elements.
5. When the timer times out 115 VAC is sent to the 3 second timer and then to the buzzer for 3
seconds.
6. When the water level reaches the high probe then 115 VAC is removed form the FILL
terminal and the fill solenoid is turned off.

7. After the water level drops below the high probe for 5 seconds 115 VAC is sent to the FILL
terminal again.
8. The red on/off rocker 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 valve allowing the steamer to drain.
•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 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
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.
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.
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 1Gallon(ea.)
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
