13. Place the probe so that neither end is in contact 

with any metal surface of the dispenser.

14. Check the voltage across terminals 1 & 3 with a 

voltmeter. Connect the dispenser to the power 

source. The indication must be:

 

a) 120 volts ac for two wire 120 volt models,

  b) 120 volts ac for three wire 120/208 volt or 

120/240 volt models,

 

c) 230 volts ac for two wire 230 volt models, after 

a delay of approximately 5 seconds.

15. Move the probe’s flat end to the tank. The indication 

must be 0.

16. Move the probe’s flat  end away from the tank. The 

indication should again be:

 

a) 120 volts ac for two wire 120 volt models,

  b) 120 volts ac for three wire 120/208 volt or 

120/240 volt models,

 

c) 230 volts ac for two wire 230 volt models, after 

a delay of approximately 5 seconds.

If voltage is present as described, reinstall the probe, 

the level control board and level probe are operating 

properly.

If voltage is not present as described, check the pink 

probe wire for continuity.

Removal and Replacement:

1.  Remove all wires from the level control board.

2.  Remove two #8-32  keps nuts holding level control 

board to right side of the component bracket.

3.  Remove level control board and spacers.

4.  Install the new level control board and spacers to 

the right side of the component bracket using two 

#8-32 keps nuts. 

5.  Refer to schematic wiring diagrams when recon-

necting the wires.
