18. With the inlet side of the Bypass Valve still only PARTIALLY open and the tank still filling slowly - it is time to
manually backwash and flush the system.

The outlet side of the Bypass Valve remains closed and in the bypass position until this flushing procedure has
been completed
19. Manually start a backwash to flush the system.
• Press and hold (5 seconds) the Extra Cycle Button until the Parameter Display flashes “BW” and the Data
Display reads “----”.
• You will hear the valve engage and it will take about 1 minute (60 seconds) until the backwash “BW”
cycle is reached.
• Once the backwash “BW” cycle begins the Parameter Display will stop flashing and reads “BW” and
the Data Display is counting down from 9:59 in 1 second increments. This backwash is a 10 minute cycle.

The Parameter Display will read “TD” for Time of Day and the Programming Icon will appear
Continue to press either Up or Down Button until the Data Display reads the current time of day.

• Current Time of Day, a PM Indicator (if applicable)
• You will also see the Time of Day alternate (about every 10 seconds) to another number and than back to
the time of day - this is normal and tells the user the next time the system will backwash counting down
each day from 6 (factory pre-set) until backwash.
