Shaft diameter < 12 mm
You can fit sensors with a shaft diameter of up to
14 mm. It is essential that you fit an O-ring with a
clamp disc to seal sensors with a shaft diameter of
< 12 mm.
Use an Allen key (width 10 mm) for dismantling to
ensure that the blanking threaded connector is not
damaged.
1.
Use the Allen key to unscrew a blanking threaded connector
out of the top of the in-line probe housing
NOTICE!
Always read the assembly instructions provided by
the sensor manufacturer
Never use a tool to install sensors with a glass
shaft. With sensors with a glass shaft, this can
cause tension in the glass shaft, which could irrep‐
arably damage the sensor.
2.
Manually screw the sensor back into the in-line probe
housing until leak-tight
Sensors with ⌀ = 25 mm
You can only fit sensors with ⌀ = 25 mm (e.g.
chlorine sensor type CLE 3) with the corre‐
sponding mounting kit (Accessories, part number
815079).
