EFOY Tutorials

EFOY
Setup

Watch our tutorial on how to setup your EFOY and EFOY Pro for the first time. We show you what you need to pay attention to in order to connect your EFOY correctly.

Refilling
EFOY service fluid

In this tutorial we will show you step by step how to easily refill the EFOY service fluid. The service fluid is only required if your fuel cell explicitly draws attention to it with a notice. This may be the case, for example, after the EFOY has not been used for a long time.
