WARNING: This product generates hydrogen gas. If hydrogen is contained and com-
bined with oxygen and an ignition source, it can create an explosion. While normal use
of this product would not create an explosion hazard, care must always be taken when
using hydrogen. Failure to operate this product in accordance with instructions set
forth in this manual can create a hazardous situation.
•
Do not use a hydrogen gas storage vessel in conjunction with the hydrogen
generator. Stored quantities of hydrogen pose an explosion hazard.
•
Normal precautions for any hydrogen supply should be taken when using the
hydrogen generator. Do NoT uSe IN A SeAleD oR uNveNTeD Room.

These instructions must be thoroughly read and understood before installing and oper-
ating the vWR Hydrogen Generator. Follow the safety standards for handling hydro-
gen gas as set forth by the National Fire Protection Agency (NFPA) Standard 50A, the
Compressed Gas Association (CGA) Pamphlet G15, oSHA Regulation 29CFR-1910.103,
and other safety governing bodies. modifications made to this unit will void the warran-
