 WARNING

These procedures must be carried out by a trained 
technician.

ELECTRICAL

•  Isolate all high voltage supplies to the transmitter before 

performing replacement procedures.

•  The wet-section is vulnerable to electrostatic damage. 

Wear an anti-static strap or dismantle the wet-section on 
an anti-static workbench.

•  Ensure all electrical connections are kept dry at all times.

GENERAL

•  Shut off the external sample supply to the wet-section 

and drain the flowcell – refer to the wet-section Operating 
instructions (

OI/ADS550-EN

) for flowcell drainage 

options.

•  When a procedure is complete, restore power to the 

transmitter and sample to the wet-section at the correct 
flow rate. 

•  If necessary, calibrate the wet-section – refer to the wet-

section Operating Instructions (

OI/ADS550-EN

) for 

calibration instructions.

•  Perform general cleaning of the wet-section using a damp
