5.1 Level Controls (Not Factory Installed)
Wire float switches, pressure switches or other level controls into the control
circuit line (prior to the switch as noted on the electrical schematic on the unit).
The following assures that the inlet valve, instruments, and pumps are not
powered when storage tanks are full: float switch assembly with cord, counter-
weight, and plastic float (used with an atmospheric storage tank).
5.2 Conductivity Meter
A factory-installed conductivity meter is mounted on the front panel of the
machine. The conductivity meter measures and displays the conductivity
resistivity of the water sample passing by unit’s sensor. The conductivity probe,
which is temperature compensated, is normally mounted in the permeate line,
but can also be mounted in the feed or concentrate line.
FEATURES:
•
Single-meter readout – indicates conductivity
•
Range –1 to 199.9

5.3 Autoflush
A factory-installed autoflush system is installed on 2,200- to 13,200-gpd models
and uses a standard 24-hour timer. It can increase the concentrate flow across
the sepralators at predetermined intervals. The timer controls a solenoid valve in
the concentrate line to increase flow.
