7500-M Neutralizer Installation & Startup Guide
*IMPORTANT*: Before any operation, the valve menu must be unlocked. If the button lock
indicator is displayed, press and hold both the Up and Down buttons for 5 seconds. A sound will
indicate the menu is unlocked. The menu will re‐lock automatically after 1 minute of inactivity.
1. To begin programming your valve, unlock the menu and press the Menu/Confirm button. This
puts the valve into program display mode, indicated by the Enquiry/Setting icon being
displayed. The Enquiry/Setting icon is displayed whenever you are changing the parameter
of a programming mode.
2. The sequence of programming modes is shown in the diagram below. To switch between
modes, press the up or down button according to which direction your mode is. The modes
can only be changed when the Enquiry/Setting button is displayed and you are not currently
modifying any other parameter.
1) To change the Time of Day:
Change programming mode to Time of Day ( [00:00] and time of day icon displayed ). The hour
and Enquiry/Setting icon will be flashing. Change the hour value with the Up/Down buttons,
then press Menu/Confirm to move onto the minute value. Change this value with Up/Down,
and press Menu/Confirm again to confirm the time.
2) To change the Rinsing Time:
The rinsing time is the hour of day that the system will turn on to perform its function. We
recommend setting the system to backwash at 2 AM [02:00], or any time that it is unlikely any
water will be used. Note the valve uses the 24‐hour clock.
The default setting is [02:00]. The max setting is [23:59]. To change, set the programming mode
to Rinsing Time ( [00:00] ). Press the Menu/Confirm button and use the Up/Down buttons to
change the hour value. Press the Menu/Confirm button again and change the minute value
using the Up/Down buttons. Finally, press Menu/Confirm to confirm your rinse time.
3) To change the Rinsing Frequency:
The rinsing frequency is how many times the system will backwash and rinse per service.
