down for any period of time. Refer to the Seasonal Shutdown section of the manual for
recommendations.
SEASONAL SHUTDOWN
The following services should be performed when the unit is to be shut down for a
prolonged time period.
1. Shut off all electrical power.
2. Close the shut-off valves in the filter inlet and outlet water lines. For units using a
backwash source other than the system, close the shut-off valve in the line from that
source also.
3. Drain all external piping to and from the filter.
4. Open the manual vent valves and open the drain line to the filter tank and piping. After
the water has drained, close the drain and vent.
5. On manual units only, rotate the valves manually by moving the linkage up and down
to ensure operation without obstruction.
6. Loosen the bolts around the circumference and remove the lid. Lubricate the bolt if
necessary. Replace the O-ring if necessary.
7. Inspect the over-drain assembly and media pack. If the media is contaminated,
remove the foreign material and replace the media if necessary. Replace the filter lid and
secure the bolts.
