BACKWASH
The backwash process is automatically engaged and controlled by your Fleck 5810XTR2
valve. Your system was pre-programmed at the factory. In most cases, your system will be
programmed to backwash every 5 days, or 2,000 gallons (whichever occurs first) at 12:30am.
There are 2 steps to the backwash process:
Step 1: Backwash: factory pre-set for 10 minutes
Step 2: Rapid Rinse: factory pre-set for 3 minutes
Unless directed by a water treatment professional familiar with this system, we do not
generally recommend that you alter the duration of any cycles, however, you can adjust the
duration of both cycles based on your water conditions through the Master Settings Mode
(see below). If you experience reduced service flow rate and pressure loss due to clogging,
it is recommended that you increase the frequency and/or duration of your backwash. If on
the mornings after a backwash your water is often discolored or has evidence of sediment,
increase the duration of the rapid rinse cycle in 1 minute increments until the problem is
resolved.
During each step of backwash, the touch screen display on the control valve will indicate the
cycle currently underway (regeneration wheel) and the amount of time remaining in that
cycle (top right corner).
There may be instances where more frequent backwash is required. For instance, if your
water consumption increases considerably, or if your feed water conditions temporarily
worsen, you may want to perform a manual backwash. You can choose to initiate a manual
backwash immediately or the next time the backwash time of day is reached:
To initiate a manual backwash:
Touch the REGENERATION ICON. You will be given a choice to either do a regeneration
immediately or to queue a backwash to occur the next time the system reaches the normal
backwash time of day.
Skip through backwash steps:
There may be times that it may be desirable to skip through backwash steps without
allowing them to fully complete. This would be most typical during servicing. When a cycle
