Maintenance

5.1.2 Sensor assembly (membrane installation)

Before starting the sensor reassembly, proceed to the sensor maintenance section for anode

and cathode cleaning instructions.

Note: The membrane support is individually machined and paired

with the sensor. For correct sensor operation, it is ESSENTIAL to

keep a membrane support with its respective sensor. Should the

membrane support require replacement, contact your Hach Lange

representative.

Install the membrane support with the groove on the upper

side.

Note: The membrane support is individually machined and paired

with the sensor. Therefore make sure that the correct membrane

support is used on the correct sensor.

Insert the prongs of the

membrane support removal

tool into the membrane

support holes.

Tighten the membrane

support finger tight.

CAUTION

Too much torque will damage the sensor electrodes.

The membrane mounting surface must be clean and even.

Replace the membrane O-ring on the sensor head with a new

one.

Note: The 29039.4 Nitril O-ring can be reused if it is still in good

condition. Membrane O-rings are part of the protection cap kit.
