   CLEVELAND RANGE OEB 20.20 
SEQUENCE OF OPERATIONS 
 
 
When using these instructions refer to the OEB 20.20 wiring schematic. 
 
1
  When incoming power (220 VAC) is connected to the combi, 220 VAC is sent to  
a
  The contacts 2,4 and 6 of the Safety Contactor (KO) 
b
  The terminals 2 and 3 of the Control Power Switch (S1) 
2
  When the Control Power Switch (S1) is turned on (closed) 
a
  The red light on the switch is energized. 
b
  Incoming power (220 VAC) is sent through the 2A fuse (F1.1) to 
•  The 12 vdc power supply (G1) 
  12vdc is sent to terminals 3 and 4 of the connector X10 on the Control 
Board (A10) 
•  Terminal 1 of connector X12 on the Control Board (A10) 
•  Terminal 10 of connector X13 on the Control Board (A10) 
•  The return of the Supply is sent to terminal 7 of connector X13 on the Control 
Board (A10) 
c
  With 220 VAC to the Control Board (A10) The Operation Board (A11) is 
energized 
•  An alarm will sound for one second 
•  All the LED’s and the display will energize one at a time. 
•  “STARTING” will be displayed for 3 seconds 
•  “please wait” will be displayed 
•  The international model number will be displayed 
•  The time and date will be displayed and this will continue until the on/off 
switch is depressed. 
3
  When the ON/OFF is depressed with the combi in the steam mode 
a
  After a date change (the first time the combi is turned on) the display will ask 
“Generator Flush?”.  If no answer is given in 10 seconds or a yes is indicated the 
flush will begin. 
•  220 VAC is sent from terminal 1 of connector X13 on the Control Board 
(A10) to the Generator Pump (M4).  
•  As the water level drops below the probes the fill solenoid (Y3) will energize. 
This rocking of the water will help flush scale from the generator. 
•  Then the pumps will be energized again 
•  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., 
b
  The display will show the set temperature and set time when the flush cycle is 
complete. 
c
  The Control Board (A10) will check the water level by looking for a ground at 
terminals 1 and 2 on connector X15.  These are connected to the high and low 
probes (B1) in the steam generator.
