In order for this product to be functional upon installation it should be stored in
accordance with the guidelines below:
• The product must be housed in a sheltered area, out of direct sunlight
and rain.
• The product should be stored to minimize the possibility of sitting in
ground water.
• The temperature within the storage environment should be maintained
between -20 to +60°C (-4 to +140°F).
• The humidity within the storage environment must be non-condensing.
• The storage environment must not expose the analyzer to any corrosive
elements.
• The product should stay assembled with its sample conditioning system
(if supplied).
• All electrical and process connections should remain disconnected and

For the period from installation of the product to commissioning start-up, the following
precautions should be followed:
• The product and associated sampling system (if supplied) must remain
isolated from the process gas, and the enclosure should remain closed to
ensure ingress protection is maintained.
• If supplied, the sampling system enclosure heating/thermostat circuit
should be operated if the climatic temperature might fall below +5°C
(+41°F).
• At time of start-up the procedures contained in the user manuals for both
analyzer and sampling system must be followed.
If the product was previously in service/operation then the following precautions should
be followed before storage:
• Upon isolation from the gas sample the entire system should be purged
with a dry nitrogen gas before powering down of the analyzer.
• All connections and ports (gas and electrical) to the analyzer or sample

• If the product is not removed from its location, the electrical grounding of
the analyzer should remain in place.
