3.3.1 Softeners
System regeneration sequence will flow in the following order.
Note:
If the following order changes then refer to the “Dealer Manual” or contact VIQUA).
•
Brine tank refill
•
4 hours (240 minutes) of softening mode while salt is dissolving
•
Backwash
•
Brine draw and slow rinse
•
Fast rinse
•
End (return to service – softening)
The system is now ready for filling with water and for testing.
1.
With the softener in the bypass mode (
Figure 2
) and the control valve in normal operation where the display shows
either the time of day or the gallons remaining, manually add 5" of water to the regenerant tank.
Note:
If too much water is put into the brine tank during softener start up, it could result in a “salty water” compliant
after the first regeneration.
During the first regeneration the unit will draw out the initial volume of brine/regenerant and refill it with the correct
preset amount.
2.
Press and hold the
REGEN
button until the motor starts. Release button. The display reads “FILL” and the remaining
time in this step is counting down. Check to verify that the regenerant tank is filling at a rate of 1/2 gallon per minute.
Since the regenerant tank was already filled in Step 1, press
REGEN
again and the display will read “SOFTENING
240". (During a full regeneration this will be a 4 hour period for salt to dissolve). Press
REGEN
again to put the valve
into “BACKWASH”. Unplug the transformer so that the valve will not cycle to the next position. Open the inlet handle of
the bypass valve very slightly allowing water to fill the tank slowly in order to expel air.
3.
When the water is flowing steadily to the drain without the presence of air, slowly open the inlet valve. Restore power
and momentarily press the
REGEN
button to advance the control to the “BRINE” position.
4.
The bypass is now in the diagnostic mode (
Figure 3
). Check to verify that water is being drawn from regenerant brine
tank with no air leaks or bubbles in the brine line. There should be a slow flow to the drain.
5.
Momentarily press
REGEN
again until the display reads “RINSE”. There should be a rapid flow to the drain. Unplug
transformer to keep the valve in the “RINSE” position. Allow to run until steady, clear, and without air. While the unit is
rinsing load the brine tank with water softener salt. Restore power.
6.
Place bypass valve in the normal operating mode (
Figure 1
) by opening the outlet bypass handle. Press
REGEN
and
the unit will return to the service position with time of day being displayed.
C A U T I O N
If water flows too rapidly there will be a loss of media to the drain.
