Installation
Replace gas cell fittings
The gas cell uses 1/4 in. standard Swagelok fittings on the gas inlet and outlets. The fittings may
need to be adapted to 6 mm if you are using metric fittings.
CAUTION
Avoid Leaks. Do not mix 1/4 inch and 6 mm ferrules and nuts. If they
are mixed or if they are attached to the wrong end of the 1/4 inch to
6 mm adapter, the connection will leak.
