Aqua-Clear Automatic Backwash (ENG/SPA)
pg. 11
Figure 8 Filter Operation
Hydraulic command tube serves two purposes in an automatic backwash system:
1. It communicates the pressure levels to the controller, which manages the backwash
2. It provides the pressure to open and close the backwash valves.
Follow the circuit diagram in
Figures 6,7 to connect the
Hydraulic Command Tubing.
The filter on the Hydraulic
Command assembly assures
that the water used to control
the valves is clean of debris.
This filter will become clogged
over time, and should be
cleaned. Closing the ball
valve upstream of the filter will
allow you to clean the filter
even when the system is in
operation. Cleaning this filter
should be a routine
maintenance check, and a
troubleshooting step any time
the backwash is not occurring
as it should.
Operation of the
Automatic Filters
The top illustration in Figure 8
shows the filters operating in
“filtration” mode. The lower
illustration shows the water
flow when Filter #1 is in
“backwash” mode. After Filter
#1 has been backwashed, the
controller will backwash Filter
#2.
