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.
