3.0 INSTALLATION
3.1 Unpacking and visual checking
Take all standard precautions when opening packages. In
particular avoid the use of long bladed cutters. Search packing
before discarding it and make sure that all of the components are
removed. Check that all pipe connections have captive seal nuts.
3.2 Mounting
Chose a site
where the ambient
temperature is
between 0°C and
40° C. and where
the analyser will
not be subjected
to vibration,
knocks or jolts. It
may be tilted etc.
in any attitude.
To install the
electronic
control/display
unit, remove the
screw side-clips (if
fitted) and slide
the unit into the
panel cut-out. Re-
fit the two clips
and tighten them
up. Dimensional
details are given in
Fig. 1
3.3 Power supply
The standard
options are 240V
AC, or 110V AC or
24V DC. Refer to the serial number plate located on the side of the
instrument for details.
