the ejection cycle ends the mo-

ment  that  the  holding  switch 

is  closed  by  the  timing  cam. 

the  water  valve  switch  is  also 

opened. If the storage bin is full, 

as  shown  here,  additional  cy-

cles will not start until sufficient 

ice is used to lower the shut-off 

arm, thus operating its switch.

near the completion of the second 

revolution  the  timing  cam  again 

closes the water valve switch. this 

time a circuit is completed through 

the water valve solenoid, its switch 

and  mold  heater.  the  water  valve 

solenoid  received  about  105  volts. 

the remaining 10 volts to the mold 

heater are not noticeable. When the 

water  valve  solenoid  is  energized, 

the valve opens and water refills the 

mold.

   DO NOT use a flame to check for gas leaks.
