Reinstall and components and reset all switches and valves for automatic operation.
Place the unit back into operation beginning with the filter flush and field flush start-up
mode. Inspect for leaks and proper operation. Check against the original flows and
pressures recorded during the initial system start-up.

ACT 100S and C200S
The ACT 100S and C200S use a small side-stream screen filter commonly referred to
as a finger filter to protect the small solenoid orifice passages.
These filters can be found mounted directly into side outlet
elbows on some models of the ACT 100S, external elbow
fittings on the 100S and C200S as well as inline couplers on
newer 100S and C200S models. The small screen filter
requires infrequent removal, but should be looked at least once
every six months on continuously operated units and those
filtering primary effluent.
Disconnect the hydraulic tubing from the fitting attached to the
finger filter. The finger filter has wrench flats which can be
used to unscrew the unit from the various housings used to contain it. Rinse and
examine the screen and examine it for clogging. A high pressure sprayer can be used
to remove stubborn residues. The finger filter can also be cleaned by soaking it in a
detergent and chlorine combination which will help to remove and oxidize organic
materials typical of primary effluent systems.
Use Teflon tape to seal the threads on the finger filter and reinstall the unit. Be sure to
reconnect the control tubing. Re-pressurize filter and inspect the finger filter connections
for leaks.
Maintenance: Miscellaneous
Other components and subsystems may require occasional maintenance. The potential
presence of a problem can be found at times by simply monitoring the unit operating
and while at rest.
Pressure
System pressure and pressure across the filter system can be monitored with
simple pressure gages equipped with a tire air chuck or tire pressure gages
capable of being used with water and air. Here you can check upstream and
downstream pressures across the filters and get a good read on how the pump is
performing. Pressure drops of 4 psi to 7 psi across a filter are a good indication
of a dirty filter and should be either back flushed or removed for cleaning.
In the field Schrader valves can be found on most of the popular air-vacuum
relief valves and can be used to monitor field conditions.
