Installation and Operation
Receiving the analyzer
When you receive the instrument, check the package for evidence of damage and if any is
found, contact the shipper.
Do not install the sensor until the analyzer is completely installed, the gas lines are
plumbed and the electrical connections are all made; and sample or a suitable low
oxygen level gas such as nitrogen or a low level span gas is ready to flow into it.
Installation
Location:
The unit is designed to be mounted in a panel in a general purpose area. It should be
mounted at a suitable viewing level. Refer to the drawing (figure 1) showing the analyzer
dimensions. It is not suitable for use in a hazardous area or with flammable gases.
Although the unit is RFI protected, do not to mount it close to sources of electrical
interference such as large transformers, motor start contactors, relays etc. Also avoid
subjecting it to significant vibration.
Precaution
Do not install the sensor until you have connected
the plumbing and power and are ready to flow
zero gas.
The sensor will become saturated with oxygen by exposure to air
for more than a minute or so, and once it is saturated, it may take many hours or
even weeks to return to a stable low reading.
