INSTALLATION INSTRUCTIONS



FREE CHLORINE SENSOR ELECTROLYTE PREPARATION

Open the 6573 membrane kit which was shipped with your 6572 chlorine probe and prepare the electrolyte
solution. Dissolve the KCl in the dropper bottle by filling it to the neck with deionized or distilled water
and shaking until the solids are fully dissolved. After the KCl is dissolved, wait a few minutes until the
solution is free of bubbles.












FREE CHLORINE SENSOR MEMBRANE INSTALLATION

Remove the protective Teflon membrane and O-ring from the sensor end of the YSI 6572 Free Chlorine
probe. CAUTION: The Teflon membrane MUST be removed for proper sensor function

.


Remove the protective cap is installed on the connector end of the probe.

Locate the 6035 Reconditioning Kit which was supplied with your 6572 Free Chlorine Probe. Use one of
circular sanding disks the 6035 Reconditioning Kit to sand the face of the 6572 Probe according to the
following instructions.

• Hold the probe in a vertical position, place a sanding disk under your thumb, and stroke the probe

face in a direction parallel to the platinum electrode (located between
the two silver electrodes). The motion is similar to that used in
striking a match. Usually 10-15 strokes of the sanding disk are
sufficient to remove black deposits on the silver electrodes.
However, in extreme cases, more sanding may be required to
regenerate the original silver surface.

• Rinse the probe tip well with purified water to remove any dust from

sanding.

CAUTION: You must sand your free chlorine sensor as described
above prior to installing a membrane to insure the surface tension
for probe surface/membrane interface.
