3.
Fully �ghten the cover. If necessary, fit a suitable metal bar between the protruding fins
on the front of the cover to provide addi�onal leverage.
4. Use the 2 mm hexagonal key supplied to �ghten the locking screw which secures the
cover.
5. Ensure
that the cer�fica�on label is in the correct orienta�on. If necessary, press and
turn the label un�l it is in the correct orienta�on.
Note:
If a new fuse fails immediately after you have fitted it, there may be an electrical fault
in the analyser: contact Servomex or your Servomex agent.

Use of the analyser with toxic gases
If you use the analyser to sample toxic gases, the concentra�ons of the gases
sampled or used for calibra�on of the analyser may be above their respec�ve
threshold limit values. You must therefore regularly leak
-
test the analyser and
associated equipment. If any leaks are found, do not con�nue to use the analyser or
associated equipment un�l the leaks have been sealed.
When you carry out a leak test, do not exceed a maximum pressure of 34.5 kPa gauge
(0.35 bar gauge, 5 psig) and do not introduce a sudden change of pressure into the
analyser. If you do, you may damage it.
If you use a liquid to assist in leak tes�ng, do not spill liquid onto any of the electrical
components in the sample/control compartment.
If you use the analyser for toxic gas sample measurements, you must regularly leak
- test the
analyser
and the associated sample inlet and outlet pipelines or hoses.
We recommend that you leak
-test the
analyser at least once every 6 months:
• If there are leaks within the analyser, it must be returned to Servomex for repair. Do not
con�nue to use the analyser
.
•
You must seal any leaks in your sample pipelines or system.
Note:
When you leak
-
test, ensure that you do not exceed the maximum pressure, and do not
increase the pressure in the analyser too quickly (see the caution above): we
recommend that you allow at least 30 seconds to fully pressurise the analyser to the
maximum press
ure.

Preventative maintenance
To minimise unscheduled analyser down�me, ensure the proper opera�on of the analyser and to comply
with the guidelines of applicable regulatory bodies, we recommend that you u�lise the SERVOSURE
annual preventa�ve maintenance program for your analyser
