INSTALLATION -
Control System
Manual systems have simple
controls, momentary buttons for
priming the filters, start and stop.
The Prime button is a
momentary switch for the feed
pump (run variable speed
setting).
The Start button does just that.
You need to hold the button
down until the Pearson Pump
comes up to full speed.
The Stop button will stop the
system.
The service switch will run the Pearson Pump only (no feed pump) on service speed
(about 1/2 speed or 10 gpm) for fresh water flushing, cleaning or pickling.
After the system is purged, use the brine discharge
valve to restrict the flow so the
Brine Discharge
Gauge reads 20 psig (absolute pressure gauge).
There must be a vacuum break on the brine
discharge line and 3 to 5 psi of back pressure on the
brine discharge to allow for smooth pump operation.
The valves in the Pearson Pump are opened and
closed by small pressure differences and this back
pressure aids the pump function. A feed pressure
adjust may be necessary after the brine discharge
pressure is set.
