DANGER
This instrument is designed to monitor the helium concentrations in a gas mixing
process. When processing gas mixtures intended for breathing, the instrument must
be calibrated and functioning properly. Suffocation or other fatal respiratory
complications can result from improperly calibrated or malfunctioning equipment.
Oxygen accelerates combustion. Do not use this instrument around open flames and
combustible gases, liquids or solids.
Only authorized personnel should conduct maintenance and/or servicing. Before
conducting any maintenance or servicing, consult with authorized
supervisor/manager.

Warranty
This equipment is sold subject to the mutual agreement that it is warranted by us free from defects of material and of
construction, and that our liability shall be limited to replacing or repairing at our factory (without charge, except for
transportation), or at customer plant at our option, any material or construction in which defects become apparent within one
year from the date of shipment, except in cases where quotations or acknowledgements provide for a shorter period.
Components manufactured by others bear the warranty of their manufacturer. This warranty does not cover defects caused by
wear, accident, misuse, neglect or repairs other than those performed by Nuvair or an authorized service center. We assume no
liability for direct or indirect damages of any kind and the purchaser by the acceptance of the equipment will assume all liability
for any damage, which may result from its use or misuse.
We reserve the right to employ any suitable material in the manufacture of our apparatus, and to make any alterations in the
dimensions, shape or weight of any parts, in so far as such alterations do not adversely affect our warranty.
Important Notice
This instrument provides measurement readings to its user, and serves as a tool by which valuable data can be gathered. The
information provided by the instrument may assist the user in eliminating potential hazards caused by his process; however, it is
essential that all personnel involved in the use of the instrument or its interface, with the process being measured, be properly
trained in the process itself, as well as all instrumentation related to it.
The safety of personnel is ultimately the responsibility of those who control process conditions. While this instrument may be
able to provide early warning of imminent danger, it has no control over process conditions, and it can be misused. Any
safeguards required such as locks, labels, or redundancy, must be provided by the user or specifically requested of Nuvair at the
time the order is placed.
Therefore, the purchaser must be aware of the process conditions and the potential for misuse. The purchaser is responsible for
the training of personnel, for providing hazard warning methods and instrumentation per the appropriate standards, and for
ensuring that all devices and instrumentation are calibrated, maintained and operated properly.
Nuvair, or the manufacturer of this instrument, cannot accept responsibility for conditions beyond its knowledge and control. No
statement expressed or implied by this document or any information disseminated by the manufacturer or its agents, is to be
construed as a warranty of adequate safety control under the user’s process conditions.

COMBUSTIBLE GAS USAGE
WARNING
This is a general-purpose instrument designed for use in a non-hazardous area. It is
the customer's responsibility to ensure safety. Combustible gases should not be
present in the immediate area nor should this instrument be used near an open flame
or ignition source.
Helium and nitrogen, while inert, can pose a suffocation risk. The customer must
eliminate the possibility of displacing atmospheric air with helium or nitrogen at or
near the instrument during the mixing or analysis process.
The customer must also ensure that the principles of operating this equipment are
well understood by the user. Misuse of this product in any manner, tampering with its
components, or unauthorized substitution of any component may adversely affect the
safety of this instrument.
Since the use of this instrument is beyond the control of Nuvair, no responsibility by
Nuvair, its affiliates, and agents for damage or injury from misuse or neglect of this
equipment is implied or assumed.
