INSTALLATION AND
SET-
UP
You must not modify the analyser in any way (either mechanically or electrically). If
you do, the cer�fica�on of the analyser will be invalidated, and it may not operate
safely.
The
analyser
must be
installed by a suitably skilled and competent technician or
engineer in accordance with this manual and to the special condi�ons of installa�on
contained within the Cer�fica�on Supplement Manual, Part Number: 01910008B.
5.1
Mechanical installation
The
analyser is not suitable for use with oxygen enriched sample gases, that is gases
over 21% O
2
, rela�ve to atmospheric pressure.
The
analyser is not suitable for use with sample vent back pressures that cause
pressurisa�on at the sample vent of 124 kPa (18 psia).
You must ensure that, when the analyser is in its installa�on loca�on:
• The opera�ng environment is within the limits specified in Sec�on
2.2.
•
Ther
e is sufficient space around the analyser to install and connect the
electrical supply (also see Sec�on
5.3.1
) and interface signal cables, and the
sample inlet and outlet pipes.
•
There is sufficient space to access the internal compartments for
maintenance.
•
The unit mus
t be mounted so that dust may only form a layer on the top
surface.
• To avoid propaga�ng brush discharges, the unit is not to be installed in a high
ve
locity dust
-
laden atmosphere.
Do not install the analyser on a surface which is subject to high levels of vibra�on or
sudden jolts. If you do, sample measurements may not be accurate, or the analyser
may be damaged.
You must mount the
analyser on a suitable rigid ver�cal surface (refer to Sec�on
2.1
for the mass of the analyser). Due to the Analyser mass, care must be taken during
moun�ng, see below.
