OPERATING INSTRUCTIONS (continued
)
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.
IMPORTANT
The filter pump running time should be 1 hour longer than the required operating time
of the Saltwater System.
