Installation & Operation Manual
5.2 INITIAL START UP
1. Make sure that all connections are secure and that any glued
piping connections or joints have had sufficient time to cure.
2. Backwash filter sand.
• Set multiport valve to backwash.
3. Turn on filter pump.
• Water will discharge from waste port.
• While pump is running, periodically check the water clarity
through the sight glass or at the waste port.
• Once water is visibly clear the backwash cycle is complete.
• See “5.1 Filter Valve Functions” on page 8 for details.
4. Turn off filter pump.
5. Set valve to rinse.
6. Stand clear of filter and turn on the filter pump.
• Water will discharge from waste port.
7. Allow filter to run for 1-2 minutes.
8. Turn off filter pump.
9. Set multiport valve to filter.
10. Stand clear of filter.
11. Turn on filter pump and allow it to run normally.
• Water will discharge to pool from return port.
• Take the pressure reading from the pressure gage while the
filter pump is running at its typical filtration RPM.
• Set the pressure gage to clean using the filtration PSI as the
“clean” mark.
5.3 OPERATING PRESSURE
WARNING
X
MAXIMUM OPERATING
PRESSURE OF THE FILTER IS
35 PSI. NEVER SUBJECT THE
FILTER TO ANY OPERATING
PRESSURE EXCEEDING 35
PSI
• Do not connect the
system to an unregulated
city water system or other external source of
pressurized water producing pressures greater
than 35 PSI.
•
This fi lter operates under high pressure. When
any part of the circulating system, i.e., fi lter,
pump, valve(s), etc. is serviced, air can enter
the system and become pressurized when the
system is restarted.
• Pressurized air in a system can cause product
failure or also cause the dial valve to be blown
off which can result in death, serious personal
injury or property damage.
• To minimize risk of severe injury or death, the
fi lter and/or pump should not be subjected to
the piping pressurization test. Local codes may
require the pool piping system to be subjected
to a pressure test. These requirements are
generally not intended to apply to the pool
equipment such as fi lters or pumps. Jandy pool
equipment is pressure tested at the factory.
If however, this
WARNING
cannot be followed and
pressure testing of the piping system must include the
fi lter and/or pump
BE SURE TO COMPLY WITH THE
FOLLOWING SAFETY INSTRUCTIONS
.
• check all clamps, bolts, lids, lock rings and
system accessories to ensure they are properly
installed and secured before testing.
• RELEASE ALL AIR in the system before testing.
• Water pressure for test must NOT EXCEED 35
PSI
• Water temperature for test must NOT EXCEED
100º F (38º C).
• Limit test to 24 hours. After test, visually check
system to be sure it is ready for operation.
NOTICE:
These parameters apply only to Jandy
equipment. for non-Jandy equipment, consult the
equipment manufacturer.
The filter is designed to operate effectively based on the
performance curve listed below. At no time is the filter
to be subjected to internal pressures greater than 50 psi.
1. After initial startup run the filter pump for several minutes.
2. Take note of the running pressure and set the “clean” indicator
on the pressure gage dial to the filtration PSI.
3. Check the operating pressure regularly at least once a week.
4. Performing a backwash procedure is required once the
pressure consistently reads 10 PSi greater than the initial
startup pressure,
DO NOT EXCEED 35 PSI.
5. Follow backwash and rinse procedure. See “5.1 Filter
Valve Functions” on page 8 and “5.2 Initial Start up”
on page 9.
6. If after backwashing the filter you are unable to get the
pressure to lower sufficiently to ensure operational pressures
below 35 PSI you will need to replace the filter sand.
