Fiberglass Sand Filter.
Filter Care
The lter is a very important part of the pool equipment and installation. Proper care and maintenance will add
many years of service and enjoyment to the pool. Follow these suggestions for long trouble-free operations:
1. To clean the exterior of the lter of dust and dirt, wash with a mild detergent and water then hose off. Do
not use solvents.
2. If internal maintenance is required, sand may be removed by removing the sand drain from the bottom of the
lter and ushing with a garden hose. Pentair Water Pool and Spa, Inc. Sand Vacuum P/N 542090 may also
be used.
3. If after a number of years, the lter tank appears foggy in color or rough in texture, the tank surface can be
painted. We recommend the use of a Quick Dry Spray Enamel. Do NOT paint the valve.
Always visually inspect filter components during normal servicing to ensure structural safety. Replace
any item which is cracked, deformed or otherwise visually defective. Defective filter components can
allow the filter top or attachments to seperate and could cause severe bodily injury or property damage.
4. The lter closure on your Triton Sand Filter was manufactured with high quality corrosion resistant materials.
This part should be carefully inspected whenever servicing your lter. If excessive leakage is noted coming
from the closure/tank interface, the closure and o-ring should be carefully inspected and replaced if any
signs of deterioration exist.
5. Your lter is a pressure vessel and should never be serviced while under pressure. Always relieve tank
pressure and open air bleeder on the lter closure before attempting to service your lter.
6. When restarting your lter, always open the manual air bleeder on the lter closure and stand clear of the
lter.
Cleaning Frequency
1. The lter on a new pool should be backwashed, and cleaned after approximately 48 hours of operation to
clean out plaster dust and/or construction debris.
2. There are three different ways to identify when the lter needs backwashing.
a. The most accurate indicator on pool systems with a ow meter is to backwash when the ow decreases
30% from the original (clean lter) ow. For example, if the original ow was 60 GPM, the lter should
be backwashed when the ow is reduced by about 20 GPM (or 30%) to 40 GPM.
b. A more subjective and less accurate indicator is to observe the amount of water owing from the ow
directionals located in the wall of the pool. The lter should be backwashed once it is detected that the
ow has been reduced by about 30%.
c. The most commonly used but less accurate indicator is to backwash when the lter gauge reading
increases 10 PSI over the initial (clean lter) reading.
3. It is important not to backwash the lter solely on a timed basis such as every three days. It is also important
to note that backwashing too frequently actually causes poor ltration. Factors like weather conditions, heavy
rains, dust or pollen, and water temperature all affect the frequency of backwash. As you use your pool, you
will become aware of these inuences.
4. If at any time the starting pressure after backwashing the lter indicates 4 to 6 PSI higher than normal starting
pressure, it is time to perform a chemical cleaning procedure.
