2-2.3. O-Ring Lubrication
Apply a very thin coat of o-ring lubricant, supplied in the YSI 6570 Maintenance Kit, to the o-rings
on the connector end of each probe to be installed. After application, the o-ring lubricant should not
be visible, but rather it will add a slight shine to the o-ring. If the lubricant can visibly be seen,
remove the excess very carefully with a piece of lens tissue (or equivalent non-shedding material,
i.e. fibreless q-tips), being careful not to get any on the probe connectors.
Caution! Make sure that there are no contaminants between the o-ring and the probe.
Contaminants that are present under the o-ring may cause the seal to leak when the sonde is
deployed.
2-2.4. Installing the Optical Probes
If you have a turbidity, chlorophyll, and/or rhodamine WT probe, it is recommended that the optical
sensors be installed first. If you are not installing one of these probes, do not remove the port plug,
and go on to the next probe installation.
Install the probe into the port, seating the pins of the two connectors before you begin to tighten.
Tighten the probe nut to the bulkhead using the short extended end of the tool supplied with the
probe. Do not over-tighten. Be careful not to cross-thread the probe nut.
The optical ports of the ADV6600 are labeled “T” and “C” on the sonde bulkhead. Each port can
accept any of the four optical sensors. Be sure to take note of which sensor is installed in which port
so that you will later be able to set up the sonde software correctly.
2-2.5. Installing the Conductivity/Temperature, DO, and pH/ORP
Probes
Insert the probe into the proper port using the diagram on the previous page as a guide and rotate the
probe until the pins engage. Seat the pins of the two connectors together as far as possible before
you begin to tighten.
The probes are held in place with slip nuts. With the connectors aligned and the two connector
halves engaged, hand-tighten the probe nut and then use the long extended end of the probe
installation tool to snug it. Do not over-tighten. Be careful not to cross-thread the probe nuts.
2-2.6. Installing the ISE Probes
The ammonium, nitrate, and chloride ISE probes do not have slip nuts and should be installed
without tools. Use only your fingers to tighten. Make sure that the probe body of the ISE probes is
seated directly on the sonde bulkhead. This will ensure that connector seals will not allow leakage.
