Gas sampling and gas conditioning technology 6-1.3.5-ME
NOTE!
The safety requirements applicable to the respective media to be
transported must be observed.
In order to prevent a disturbing accumulation of heat, the pumps
should be installed away from sources of heat and freely ventilated.
For installation outdoors, the pump must be installed in a
protective housing frost-free in winter and sufficiently ventilated in
summer. Direct exposure to sunlight must be avoided.
NOTE!
Pumps have mechanical moving parts that can induce vibrations.
To prevent damages at the pump or at peripheral components /
facilities as well as minimizing noise development an appropriate
vibration decoupling is necessary. For this M&C can deliver e.g.
anti-vibration pads.
This explicit is also valid for the connection of the sample lines at
the pump head.
11.1 MECHANICAL
The fixing dimensions are shown in Figures 2 and 3.
The pumps must be installed in such a way that the impeller is able to draw in sufficient cooling air.
The pumps should be installed at the highest point in the system and/or with the pump head
pointing downward to prevent an accumulation of condensate – this will extend the useful life of the
pump.
11.2 ELECTRICAL
Electrical installation must take place in compliance with the safety regulations. Before connecting the
pump, safe isolation from the supply must be ensured.
The protective conductor must be connected to the pump motor.
A device for disconnecting the pump from the electrical system must be provided in the electrical
installation (according to EN 60335-1).
The supply circuit should be provided with a fuse with a rating corresponding to the current
consumption (over-current protection, current consumption, see technical data).
WARNING!
The supply voltage must be compared with the voltage shown on
the rating plate. A voltage deviation of about 10% is admissible.
The pumps must be mounted so that contact with live parts (e.g.
electrical connection, possibly motor windings) is excluded.
