OPERATING INSTRUCTIONS (continued)
English
5. Switch off the pump, change the 6-way valve to “RINSE” position (see
drawing 16) .
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 14) .
8. Switch on the pump. The system is now operating in the normal filtering mode.
Run the pump until the desired pond 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 pond 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 pond 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.
