MAINTENANCE OF THE ELECTROLYSER
This device is designed to provide many hours of service with minimal and easy maintenance. Proper
care and maintenance by qualified personnel help to maximise the operating life of the device.
Routine Maintenance
The device should be inspected at least once a year for apparent signs of physical deterioration. All
hydrogen connections must be tested for leakages regularly; Enapter recommends using one of the
techniques listed in the Appendix I.
After commissioning, the process tank must be emptied at least once a year and new electrolyte filled
into the device. For more information, please refer to Appendix III, which details the draining process
of the device, and then follow the instructions for the Manual refilling of electrolyte. It is
recommended to clean the device at the same time as described in the chapter Cleaning.
Depending on the frequency of use it is possible that the process tank needs to be emptied and refilled
more often than once a year. By connecting your device to the cloud, it is possible to receive alerts
when the device voltages start increasing – this typically signifies a needed electrolyte change. After
the electrolyte change, the electrolytic stack will return to a lower voltage, decreasing power
consumption of the device and increasing its efficiency and lifetime.
Warning!
Any maintenance activities, excluding the ones listed in the Routine
Maintenance and installation sections, are only allowed to be performed
by trained technicians!
Shut down the device, remove the power and wait until the device is cooled
down before working on it in any way.
Wear PPE always during the maintenance of the device.
Do not open the device!
During maintenance, avoid heat in the vicinity of the device and the hydrogen
source. No smoking, no naked flames.
Prevent electrostatic charging of the device.
Before starting to work on the device, ensure you are aware of the local
health and safety rules and regulation, as well as action plans if an accident
occurs.
Cleaning
When performing the routine maintenance processes and checks, the device should be inspected and
cleaned. Start by carefully using a vacuum cleaner (not included) to clean out the ventilation
openings/grills. Afterwards, use a damp cloth (no acids, aggressive or abrasive substances) to clean
the outside of the device.
