will show the progress and time remaining
for the purge cycle.

valve so it will only read feed pressure when the system has
been started (so the feed valve opens and shows the feed
(boost) pressure, which should be about 20 psi during opera-
tion.
If the optional boost pump was included the pressure can be
adjusted with the knob on the boost pump control box.
8. Using the buttons on top of the filter housings, bleed out the air in
the filter housings until water is coming out.
9. Check the brine discharge for water flow. The system
should fully prime within 60 - 90 seconds and all air
should be out of the feed water hoses. The pump will
should sound smooth and if there is any knocking ad-
just the feed pressure up or down until the pump is
running smoothly. Note if the boost pressure drops
below 10 psi, the system will alarm and tell you to check the pre
- filters.
Note: If you must stop the purge sequence for any reason, the control will de-
fault back to the beginning of the purge cycle to protect your system.
