9.Terminal Block #11 [TB-11] has three [3] pairs of terminals. The first pair of terminals are low voltage connections for the detergent low level probe. The probe should be installed in the detergent container so that it does not protrude above the top of the detergent pump inlet strainer. [fig. #9] This is intended to prevent cavitation of the pump and will advise when the tank needs to be refilled. The probe rods may be cut to facilitate a neat and effective installation.
