Filter Care

The filter 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 filter 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 filter and flushing with a garden hose. Pentair Sand Vacuum P/N 542090 may also be used.
3. If after a number of years, the filter 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 separate and could cause severe bodily injury or property damage.
4. The filter closure on your Triton Sand Filter was manufactured with high quality corrosion resistant
materials. This part should be carefully inspected whenever servicing your filter. 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 filter is a pressure vessel and should never be serviced while under pressure. Always relieve
tank pressure and open air bleeder on the filter closure before attempting to service your filter.
6. When restarting your filter, always open the manual air bleeder on the filter closure and stand clear
of the filter.

Cleaning Frequency

1. The filter 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 filter needs backwashing.
a. The most accurate indicator on pool systems with a flow meter is to backwash when the
flow decreases 30% from the original (clean filter) flow. For example, if the original flow was
60 GPM, the filter should be backwashed when the flow 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 flowing
from the flow directionals located in the wall of the pool. The filter should be backwashed
once it is detected that the flow has been reduced by about 30%.
c. The most commonly used but less accurate indicator is to backwash when the filter gauge
reading increases 10 PSI over the initial (clean filter) reading.
3. It is important not to backwash the filter solely on a timed basis such as every three days. It is
also important to note that backwashing too frequently actually causes poor filtration. 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 influences.
4. If at any time the starting pressure after backwashing the filter indicates 4 to 6 PSI higher than
normal starting pressure, it is time to perform a chemical cleaning procedure.
