Manual Regeneration or Backwash
To initiate a manual regeneration or backwash, simply
press and hold the REGEN button for 3 seconds. If an
immediate second regeneration or backwash is
desired, wait for at least one minute after the first
regeneration or backwash begins and then press and
hold the REGEN button for 3 seconds. A second
regeneration or backwash will be performed
immediately following the first. The display will freeze
and only show the Regeneration Time Remaining as an
indication that the second regeneration or backwash
will be initiated.
When the first regeneration or backwash is complete,
the second regeneration or backwash will begin and
the display will alternate between Flow Rate and
Regeneration Time Remaining.
Note: Series 962M and 962S Twin Alternating Systems
have a two minute time period, after the manual
regeneration button is pressed, where the standby unit
drives to service. If an immediate second regeneration
is required of the OTHER unit in the system, wait for at
least three minutes after pressing the manual
regeneration button the first time, then press and hold
the REGEN button for three seconds.
Battery Backup
If the battery backup is provided with the Series 962
control, make sure that it is properly connected.
Reference pages 32 and 33. Water usage and time of
day will be maintained. The control has a trickle charge
circuit that will recharge a rechargable but not a
standard battery in the event it is depleted by a power
outage.
