Section 6. Maintenance
6.1 General Maintenance
1.
Wash outside of fi lter with a mild detergent and
water. Rinse off with a hose. Do not use solvents
to clean the fi lter. Solvents will damage the
plastic components of the fi lter.
2.
Inspect the DE fi lter grids at least twice a year.
Remove any foreign material that has not been
backwashed out of the system.
3.
Check pressure during operation at least once a
week.
4.
Remove any debris from the pumps and pool
skimmer baskets.
5.
Check pump and fi lter for any leaks. If any leaks
develop, turn off the pump and call a pool service
technician.
6.
Product safety signs or labels should be
periodically inspected and cleaned by the product
user as necessary to maintain good legibility for
safe viewing distance.
7.
Product safety signs or labels should be replaced
by the product user when a person with normal
vision, including corrected vision, is no longer
able to read the safety signs or label message panel
text at a safe viewing distance from the hazard.
In cases where the product has an extensive
expected life or is exposed to extreme conditions,
the product user should contact either the product
manufacturer or some other source to determine
means for obtaining replacement signs or labels.
Caution
Be sure that all provisions for wastewater disposal
meet local, state or national codes. One hundred
gallons (100 gals.) or more of pool water will be
discharged during fi lter backwashing. Do not
discharge water where it will cause fl ooding or
damage.
8.
Installation of new replacement safety signs or
labels should be in accordance with the sign or
label manufacturer's recommended procedure.
6.2 Backwashing
1.
With the fi lter pump off, set the backwash valve
or diverter valve handle to the "BACKWASH"
position.
Caution
Maintain your pressure gauge in good working order.
The pressure gauge is the primary indicator of how
the fi lter is operating.
2.
Open the air release valve.
3.
Stand clear of the fi lter and start the pump to
circulate the water backwards through the fi lter to
the waste line.
4.
When a steady stream of water is expelled through
the air release valve, close the valve.
5.
Run the pump until the backwash discharge water
is clear (repeat steps 1 thru 5 if required).
6.
Switch the fi lter pump off.
7.
Follow the procedure for coating the fi lter grids as
described in Section 4.2.
6.3 Pressure Gauge
1.
During operation of the fi ltration system, check
the pressure gauge/air release assembly for air or
water leaks at least once a week.
2.
Keep the pressure gauge in good working order.
If you suspect a problem with the gauge, Zodiac
recommends that you call a service technician to
do any work on the fi lter/pump system.
6.4 Cleaning the Filter Grids with Water
1.
Turn off the pump and switch off the circuit
breaker to the pump motor. Open the air release
valve on top of the fi lter tank. Close the fi lter
isolation valves. Remove the drain plug.
2.
Once all pressure has been relieved, remove the
clamp ring and the fi lter lid. Inspect the o-ring for
cracks or tears and replace if necessary.
3.
Remove the fi lter grid assembly from the fi lter.
Follow the instructions in Section 5.1.
4.
Using a garden hose, thoroughly fl ush all
contaminates from the fi lter grid surfaces.
