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 power light.
• 115 VAC is sent to normally open drain valve closing it.
•
115 VAC is sent to H and N on the water level board
3. With the water level board energized and no water in the generator
• 5 seconds later 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 to the heat standby timer which will energize 3 seconds every 4
minutes to maintain heat while unit is idle
• 115 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
• 115 VAC is sent from the timer to the R2 relay coil
• R2 relay energizes closing the R2A and R2B contacts
• 115VAC is sent through the now closed R2B contacts to the timer motor
• 115 VAC is sent through the now closed R2A contacts through the door switch to the
normally closed contacts of the high limit switch.
• 115 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.
• 115 VAC is also sent through the high limit to 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 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
• 115 VAC is sent to the 3 second timer and then to the buzzer for 3 seconds.
• 115 VAC is removed from the R2 relay.
• R2A contacts open de energizing the heat circuit
• R22B relay contacts open removing the 115 VAC from the timer motor
7. When the water level reaches the high probe then 115 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 115 VAC is sent to the FILL
terminal again.
9. The red on/off switch is depressed and the unit is turned off.
• 115 VAC is removed from the heat and timer circuit.
• 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.

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.
