IntelliFlo VF 3050 pump setup
(Continued)
Backwash parameters
When the pump detects that the filter differential pressure (10 PSI difference) has increased and is now
at the “Clean Filter” pressure, IntelliTouch displays an alert message. This means that the filter must be
cleaned (backwashed) to reduce the pressure. To do this, the pump must be stopped and the IntelliTouch
outdoor control panel must be in “Service” mode (press the Auto button and select “Service” mode. To
start the backwash flow operation, press the Start/Stop button on IntelliFlo, then press the Backwash
button. The pump will run the preset cycle time and preset flow GPM). The flow will be adjustable to
accommodate the specific filter backwash flow requirement. After the backwash cycle is finished, the
“Rinse” cycle with the preset duration time will be executed. After these cycles have been completed or
if the Start/Stop button is pressed to stop the process, the filter status will be recalculated and the zero-
pressure measured when Filter mode is operated again.
When using cartridge filters the backwash cycle must be performed when cleaning or replacing filters.
This helps the IntelliFlo reset its zero head pressure level. If you are charging a DE system, charge the
system first during a normal running cycle. After the filter is charged, run the pump in backwash mode
with the filter valve in the filter position to reset the % clean filter status. Then run the pump in filter
mode.
Note:
IntelliFlo will ramp up to full speed if necessary to achieve the commanded flow. Be sure that the
system can withstand the resultant pressures.
To set the backwash parameters:
1. From the main pump screen, press the left
side button next “INTELLIFLO”.
2. On the next screen, press the left side button
next to
SET PARAMETERS
then on the
following screen select
BACKWASH
PARAMETERS
.
3. To adjust each of the parameter values,
use the right button to increase and the left
button to decrease the value.
Description Value
Clean Filter PSI - (Default is 14 PSI)
The average PSI setting is between
10 PSI and 20 PSI for most pools and
filters. The entered PSI value splits the
percentage meter for the filter. When the
“clean filter” value is reached, IntelliTo-
uch displays an alert message and the
pump stops monitoring flow rates and
starts managing pressure. The value rep-
resents the change in pressure over time
from start up (system clean) to present
day (system getting dirty). The changes
can come from anywhere in the system,
for example clogged skimmers or pots
in pumps. Setting this parameter at a
lower level will cause the alert message
to come up sooner and you will have to
clean your filter (cartridge) or backwash
your filter (sand or DE) sooner.
