3.1.3 Attaching sensors
Note

When attaching or replacing a sensor, wipe any moisture off the sensor probe and sensor.

Be sure to keep water out of sensor connectors. If moisture comes in contact with a sensor
connector, blow-dry it with dry air.

The sensor probe is not waterproof when the sensor is not mounted.

Take care not to tighten the sensor too much.

Attaching the pH sensor
1. Remove the sensor guard.
2. Remove the sensor plug.
3.
Coat the pH sensor O-ring with a thin layer of silicon grease (part No. 3014017718).
Note
Be sure no grease from the O-ring gets on the sensor connector. If the sensor connector gets grease
on it, wipe it off with a soft cloth soaked in alcohol.
4.
Make sure there is no moisture on the sensor probe’s sensor connector (marked
"pH").
5. Fasten the pH sensor securely by hand.
6.
Clean the sensor with an alcohol-soaked cloth.
Note
Do not throw away the black cap which has been put on the tip of the sensor. It will be used for the
storage.
