Cleaning and maintenance 6.1 Cleaning the instrument Prior to cleaning the instrument, always switch off mains and un- plug the power cord! When handling cleaning detergents, follow the instructions of the manufacturer and make sure all laboratory regulations in force in your country are complied with.
The instrument is virtually maintenance-free in operation. To ensure smooth operation of the instrument over many years we do, however, recommend the following: • Have the instrument inspected once per year by a qualified service en- gineer authorized by Leica. • At the end of the warranty period, enter into a service contract. For more information, please contact your local Leica technical service center. Leica ST5020...
Cleaning and maintenance 6.3 Preventative maintenance schedule Maintenance activity daily weekly monthly Clean the TFT screen with a lint-free cloth. √ Follow the manufacturer's instructions when using screen cleaner. Clean outside surfaces of instrument and lid with soft √ cloth. Use cleaning detergent, if necessary.
Troubleshooting 7.1 General The Leica ST5020 is equipped with a troubleshooting system. If an error is detected, detailed error messages and corresponding user instructions on what to do are displayed on the touch screen. For all correctable error conditions the instrument will take corrective ac- tions to protect the specimens.
Page 80
Troubleshooting 1. Read the error message, acknowledge the alarm and, immediately afterward, press the "PAUSE" knob. The transport arm moves into a se- cure position. The instrument is now in pause mode and the instrument cover can be opened. Caution! As long as the level sensor is covered with water, the water flow cuvettes' (7-12) water valves are closed.
