For routine maintenance, new electrolyte solution must be prepared. Regular changing of the
electrolyte in the electrolyser helps to prolong the lifetime of the device. This solution can generally be
purchased locally. However, if you are struggling to source the materials involved, please contact the
Enapter customer support team. For more information please take a look here.
Warning! Refer to the Material Safety Data Sheet (MSDS) of all chemicals used, before
handling them. All persons using, preparing, and filling the electrolyte into the devices
must be informed about any potential hazards involved with their activities.
Attention: Mix the electrolyte solution in accordance with good industrial hygiene and
safety practice and wear appropriate Personal Protective Equipment as specified by the
relevant Material Safety Data Sheet (MSDS). Avoid any contact with eyes and skin.
Attention: Carefully read the instructions below before beginning work. Follow the
instructions – in case of questions, please contact the Enapter customer support team.
Ensure all material used to store and contain your electrolyte solution is chemically
compatible with its contents.
1. Put on PPE. The minimum required equipment are safety goggles to protect from splashes and
nitrile gloves. Ensure your working area is clean to avoid chemical contamination and potential
exposure hazards.
2. Ensure the selected KOH resistant container is large enough to contain the solution entirely. Verify
the container is clean, and no debris is visible inside. If you are unsure – go to step 3, otherwise,
skip to step 4.
If you are preparing the solution in advance – clearly mark and label the solution. Keep out of
the reach of children and untrained persons. Never store chemicals above eye-level.
We recommend to contact Enapter to make sure that the purchased product is compatible
