Do NOT attach the H2 Fill Adapter to the Probe Port! This will lead to a costly repair.
To avoid this scenario, follow these precautions:
|Keep a Probe connected to the device at all times.||Keep the H2 Fill Cap in place at all times
(Except, of course, when you’re filling the phx21 with Hydrogen).
For information on the proper use of your phx21, please refer to the phx21 User Manual.
