1. Put on PPE. The minimum required equipment are safety goggles to protect from splashes and
nitrile gloves. Ensure the working area is clean to avoid chemical contamination and potential
exposure hazards. Enable maintenance mode using the Enapter App.
2. Attention: the device should be kept powered on, if possible.
3. Prepare the container to catch the drained liquid and insert the end of the drainpipe into it.
4. Take out any tube or fitting attached to the "O
2
VENT" to let the air fill into the tank when the
solution is drained.
5. Fully insert the supplied male CPC quick connector into the valve bulkhead labelled "FILL/DRAIN".
The solution will start pouring out immediately. Place the container below the port to fully drain
the electrolyte.
6. Collect the drained liquid in an appropriate container and place in a chemical waste container. Do
not flush to sewer. Dispose of the liquid in compliance with all relevant local safety guidelines, rules,
directives and regulations.
7. Once electrolyte stops pouring, safely remove the drain connector. To disconnect, push the button
and pull the connector out of the bulkhead.
8. If the electrolyte is drained for maintenance, be aware that fresh water will be filled up via the “H
2
O
IN” port. The app guides through the necessary steps. After the refill, more drains and refills will be
needed until the electrolyser can be filled up again with electrolyte.
