4.5 INSTRUCTIONS FOR CONNECTING STAINLESS STEEL PIPES
The stainless steel connections need tube fittings with ¼” outside diameter for the H
2
pipes and ⅜”
outside diameter for the O
2
pipe. The outlets to be connected according to these instructions are
labelled “H
2
OUT” and “H
2
VENT” as well as “O
2
VENT” on the front panel of the device.
Follow the instructions of the fittings manufacturer carefully to install leak tight connections.
Always check each connection for leaks! Metal to metal fittings can be used but remounting them is
not recommended due to possible leakages. For more information, please refer to Appendix I below.
