Replacing valve hoses

To replace the hoses, proceed as follows:

1.

Rinse the old hoses first with water and then with air to empty them (see SERVICE).

2.

Remove the hoses from the valves: a. You can disconnect the front hoses directly because the valves are open when deenergised.

b. To remove the back hoses, press the black button on the valve and disconnect the hoses.

3.

Grease the new hoses with silicone grease before inserting them.

4.

Install the new valve hoses in the reverse sequence of operations.

Ensure that the hoses are connected correctly.

5.

After installation, refill the hoses with sample, standard or cleaning agent (SERVICE).

6.

Carry out an offset calibration and a calibration.

2) Make sure that the hoses are bubble-free when filled. If not, check the sample flow rate (see below).
