GENERAL OPERATING INSTRUCTIONS
• Before start-up unscrew transfer safety lock (knurled-head screws) of the MLT 1 + 2
(section 5. of operation manual) !
• Installation area has to be clean, free from moisture, excessive vibration and frost-
protected. Take care to meet the permissible ambient temperatures as given in the technical
data section!
Instruments must not be exposed to direct sunlight, fluorescent lamps nor sources of
heat.For outdoor installation it is recommended to mount the instruments into a cabinet.
At least sheltering against rain is required. Do not cover venting openings and take care
to mount the instrument in a distance to walls not affecting venting.
• Free flow of air into and out of the MLT (ventilation slits) must not be hindered by
nearby objects or walls !
• Do not interchange gas inlet and outlet! All gases must be conditioned before supplying!
When supplying corrosive gases ensure that gas path components are not affected!
• Max. permissible gas pressure: 1,500 hPa, except instruments for gas purity measurement
(see chapter 5.4.3.1), with integrated valve blocks (see page 5-8 and/or paramagnetic
Oxygen sensor (see table page 20-4)!!
• Exhaust lines must be installed in a descending way, need to be pressureless, frost-
protected and in compliance with applicable legislative requirements!
• When it is necessary to open gas paths seal the analyzer‘s gas fittings by using PVC
caps to avoid pollution of the internal gas path by moisture, dust, etc.
• To stay in compliance with regulations regarding electromagnetic compatibility it is
recommended to use only shielded cables, as optionally available from Emerson Process
Management or equivalent. Customer has to take care that the shield is connected in
proper way. Shield and signal connector enclosure need to be conductively connected,
submin-d plugs and sockets must be screwed to the analyzer.
• Using external submin-d-to-terminal adaptor elements (option) affects electromagnetic
compatibility. In this case the customer has to take measures to stay in compliance and
has to declare conformity, when required by legislation (e.g. European EMC Directive).
