Need Customer Support for Your 94B-4 Backwash Control Panel?

Updated: Jul 20, 2022

Understanding the 94B-4 Series Backwash Controls


The 94B-4 Series line of controls, are solid-state filter backwash controls, capable of operating one master valve, and up-to 12 backwash valves. The control will initiate a backwash cycle after reaching a pre-determined time or by receiving a signal from the pressure switch indicating a dirty filter condition. ( LCD Monitor models are also available through the 94B-4L, 94B-8L, and 94B-12L line ).


The 94B-4 Backwash Control is shipped ready for most normal installations. However, certain situations will require fine tuning of the P.D. Delay, timer mode, and last station backwash settings. This is accomplished by locating the DIP Switch assembly on the back of the control panel ( see image below ) and making final adjustments.

Depending on the number of tanks you have, that will dictate which switch must be up.

C. SLAVE SWITCH

D. PRESSURE DIFFERENTIAL SWITCH DELAY

E. OFF-POSITION OF DIP SWITCH
