5. Switch off the pump, change the 6-way valve to “RINSE” position (see
drawing 25) .
6. Switch on the pump and run the pump for about one minute to level out the
sand bed after backwashing the sand media.
7. Switch off the pump, change the 6-way valve to “FILTER” position (see
drawing 23) .
8. Switch on the pump. The system is now operating in the normal filtering mode.
Run the pump until the desired pool water clearance is obtained and no more
than 12 hours per day.
9. Record the initial pressure gauge reading when the filter media is clean.
NOTE: During initial setup of the system, it may be necessary to backwash
frequently due to unusual heavy dirt present in the water and sand. After that,
as the filter removes dirt and impurities from the pool water, the accumulated
dirt in the sand media will cause the pressure to rise and the flow to diminish. If
there is no vacuuming device attached to the system and the pressure gauge
reading is in the yellow zone it is time to backwash the sand media, see
“BACKWASH” under “initial startup and operation” section.
Vacuuming device (i.e. Intex auto pool cleaner) attached to the system may also
cause the flow to diminish and the pressure to rise. Remove any vacuuming
device from the system and check if the pressure gauge reading has dropped
from the yellow zone to the green zone.
