8.
Turn the pump off and set valve to "Filter" position. Be sure that
all pool suction and return lines are open so that water is free to
flow from and to the pool.
9. Open the manual air bleeder on the filter. STAND CLEAR OF
FILTER and start the pump.
10. Close the air bleeder on the filter when a steady stream of water
emerges.
11. The filter has now started its filtering cycle. Verify that water is
returning to the pool and take note of the operating pressure. The
original starting pressure is ___________ psi with the filter clean.
12. Check the system for water leaks. If a leak is found, shut the
pump off before correcting the leak.
13. As the filter removes dirt and impurities from the pool water, the
accumulation will cause the filter pressure to rise and flow to
diminish. When the pressure gauge reading is 10 psi higher than
the clean filter reading noted above, it is time to backwash the
filter.
General Maintenance
Proper care and maintenance of the pump and sand filter system will
add many years of enjoyment to the pool. Follow these suggestions
for long trouble free operation.
1. To clean the exterior of the pump and sand filter system of dust
and dirt, wash with mild detergent and water and then hose off.
Do not use solvents.
2. If internal filter maintenance is required, sand may be removed by
removing the entire drain spigot from the bottom of the filter and
flushing with a garden hose.
3. The filter is a pressure vessel and should never be serviced
while under pressure. Always relieve tank pressure and open air
bleeder on filter before attempting to service the filter.
4. When restarting the filter always open the manual air bleeder on
the filter and STAND CLEAR OF FILTER.
5. The strainer basket in the pump should be inspected and cleaned
twice each week. Remove the clear lid and the basket, and clean
debris from basket. Inspect the lid o-ring; if damaged, replace.
The pump seal requires no lubrication. The pump motor should
only be serviced by a motor service center.
