Shutting down and storing the EFOY Fuel Manager
You can fully empty the EFOY Fuel Manager by doing the following:
Before shutting down the EFOY Fuel Manager, S 8.1, unscrew all
SEE ECTION
the fuel cartridges, but let your EFOY fuel cell continue to run (active
charging operation is required!). Only when the EFOY fuel cell displays the
"empty fuel cartridge" error is the EFOY Fuel Manager completely free of
methanol.
Use this procedure only if it is absolutely necessary. Otherwise, we
recommend shutting down the EFOY Fuel Manager as described in
S 8.1.
