Instruction manual

HS2 and HS2P

The procedure for replacing the rods is as follows:

1. If using the HS2P, slip off the plastic bumper.

2. Use the wrench (pn 26156) to unscrew the rods.

3. Ensure that the threads of the replacement rods and the sensor body are

clean and free from damage.

4. Apply thread locking compound (pn 13665) on the threads of the

replacement rods.

Use the thread locking compound sparingly. A thick coating

may affect measurements. The small tube of Loctite

222MS Threadlocker that is shipped with the HydroSense II

is enough to treat several sets of rods.

5. Use the wrench (pn 26156) to screw in the rods. Full contact between the

rod’s nut and sensor body is required for proper operation.

Do not over tighten the rods. This can damage the threaded

inserts of the sensor head, permanently damaging the

sensor.

6. If using the HS2P, put on the plastic bumper.

7. Wait 3 to 12 hours before using the HydroSense II to allow the thread

locking compound to cure. The required curing time depends on

temperature. Allowing the threading compound to cure prevents loosening

of the rods.
