Operation And Maintenance; Initial Start-Up - Pentair STA-RITE SAND DOLLAR Installation And User Manual

Initial Start-Up

1. Be sure the correct amount of silica filter sand is in the tank and
that all connections have been made and are secure.
2. Verify that the backwash is open so that water is free to flow
from the pool and out the backwash line. Set the control valve to
"Backwash" position.
This filter operates under pressure. With the valve clamped properly
and operated without air in the system, this filter will operate in a safe
manner. Air entering the filter and the valve not clamped correctly can
cause the valve to separate, which could cause serious personal injury
and/or property damage.
Always turn pump off before changing valve positions. Changing valve
positions while the pump is running can damage the control valve, which
may cause serious injury or property damage.
3. Check the valve clamp on the filter for proper installation. For
valve clamp installation instructions, see "Installation" on
page 2.
4. Open the manual air bleeder.
(See Figure 3 for air bleeder
location). STAND CLEAR OF
THE FILTER. Prime and start
the pump according to the
pump instructions allowing
the filter tank to fill with water.
Close the air bleeder on the
filter when a steady stream of
water emerges.
5. Once the water flow is steady
out the waste line, run the
pump for at least two minutes.
This initial backwashing of
the filter is recommended to remove any impurities of fine sand
particles in the silica sand media.
6. Turn the pump off and set valve to "Rinse" position. Ensure that
all pool suction and return lines are open so that the water is free
to flow from the pool to waste. STAND CLEAR OF FILTER and
start the pump.
7. Run the pump for at least two minutes.
