The information in this section is to be used by qualified service
trained personnel only. To avoid injury, do not perform any service or
maintenance procedure described in this section unless you are properly
trained.
6.1
Scheduled Maintenance
The IR7000 does not require any periodic maintenance beyond
normal cleaning and filter replacement. In cases where the analysis is
performed on a hazardous gas, a routine leak checking procedure should
be adopted.
6.1.1 Cleaning
To clean the exterior surface of the analyzer, use a mild solution of
soap and water and apply with a dampened cloth. Do not use solvents. Do
not spray or apply any liquid directly onto the case or front panel.
6.1.2 Particle Filter
The sample path in some versions of the IR7000 is equipped with a
disposable 0.3-micron particulate filter. This filter is not meant to be the
primary sample filtering device. If the primary sample filter fails this
filter may become clogged. This will increase the backpressure inside the
system and reduce the flowrate. The filter should be checked periodically
and replaced as necessary.
To replace the particulate filter:
WARNING: Depending on the sample system used, sample gas may be still
flowing in the sample lines. Make sure that the sample gas is turned
off before beginning this procedure.

•
Flush the instrument lines with nitrogen for 15 minutes.
Turn off the instrument and disconnect the power cord. It is
recommended that you install a lock-out device so that the
instrument cannot be powered back up unless the lock-out
device is removed.
