• 220 VAC is sent from terminal 3 of connector X12 on the Control Board
(A10) through the normally closed auxiliary contacts of K2 and K1 to the coil
of Contactor K4 until the cabinet reaches the set temperature as sensed at
probe B6.
◊ The contactor K4 closes and to legs of the 220 VAC is sent to the 18 KW
element (E4)
• 220 VAC is sent from terminal 7 of connector X11 on the Control Board
(A10) to the coil of Contactor K44 until the cabinet reaches the set
temperature.
◊ The contactor K44 closes and the third leg of 220 VAC is sent to the 18
KW element (E4)
◊ If the reduced power option is chosen then the K44 Contactor is not
energized.
d The steam circuit is energized.
• 220 VAC is sent from terminal 4 of connector X12 on the Control Board
(A10) to the coil of the Y3 solenoid allowing water to be thrown against the
element until the bypass probe (B5) senses 154 degrees F.
e When the condensate box is heated to 140 degrees F at the B3probe, 220 VAC is
sent from terminal 5 of connector X12 to the condenser valve (Y1) until the
temperature drops.
f When the timer counts to 0 or the core temp probe (B10) reaches the set amount
the cycle ends and the steam generator reverts to the standby temperature of 190-
degree F.
