Removing Old Wear Parts

Remove Cover Screws

Use a Philips #1 screwdriver to remove 2x screws from the sensor cover.

Maintain Pressure & Rotate Sensor Vertically

Keep pressure on the cover to prevent components from shifting.

Remove the Sensor Cover & Impeller

Slowly take off the sensor cover, then remove the magnetically coupled impeller.

Remove the Wear Ring

Carefully extract the wear ring from its groove.

Clean Sensor End

If fouling is present, clean using Isopropyl Alcohol and a lint-free cloth. (Avoid scratching the electrode surface.)

Installing New Wear Parts

Install New Wear Ring

Place the new wear ring into the groove.

Insert New Impeller

Place the new impeller into the impeller well.

Add Cleaning Beads (x15)

Place 15 cleaning beads inside the sensor end cover. (Ensure beads stay in the electrode compartment.)

Align Components Properly

Align the temperature sensor and impeller with their respective holes in the sensor cover.

Lower Sensor into Sensor Cover

Gently twist the cover until the guide pins drop into place.

Secure the Cover Screws

Insert and tighten 2x cover screws until the sensor cover is fully secured. (Do not overtighten to prevent motor binding.)

Testing the Sensor After Wear Part Replacement

Power On the Sensor

Ensure the impeller spins freely.

Check for Impeller Resistance

If the impeller does not spin, loosen the cover screws ¼ turn at a time until rotation starts.

Perform a Water Test

Submerge the sensor in a bucket of water to confirm water flow from the ejection port.
