11 INSTALLATION INFORMATION
The safety rules and regulations for the prevention of accidents must be observed during installation
and also subsequent operation. The information in Chapter 3‚ “Safety” must be observed.
Gas sampling and gas conditioning technology 6-1.3.5-ME
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.
NOTE!
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.
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
NOTE!
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
11
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).
The supply voltage must be compared with the voltage shown on
WARNING!
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.
Gas sampling and gas conditioning technology 6-1.3.5-ME
11.3 PNEUMATIC
12
Components to be connected to the pump must conform to the pneumatic
data of the pump.
NOTE!
Remove safety stoppers from threaded gas connections (thread size G1/8”).
Accessories such as threaded hose couplings must be screwed into the threaded connection with
sealing tape (the use of sealing tape is unnecessary when using M&C couplings).
Connect suction and pressure pipe.
Do not interchange hose connections for sample gas inlet and outlet; the
connections are appropriately marked.
NOTE!
After connecting all pipes, they must be checked for tightness.
When connecting the hoses to optional threaded hose couplings, the following should be noted:
The tightness of the connection can only be ensured when the connecting
NOTE!
hose has a straight terminating edge (use of a hose cutter).
Loosen the swivel nut of the clamping ring by turning anticlockwise; it must be ensured that the nut
is carefully removed from the coupling, so that the clamping ring lying loosely in the clamping ring is
not lost.
Slide the swivel nut on to the connecting hose.
Slide the clamping ring with the thicker part pointing towards the nut on to the connecting hose.
Fit the hose on to the supporting nipple in the coupling;
Tighten the swivel nut hand-tight.
The hose is not connected non-slip and pressure-proof.

12 COMMISSIONING
Prior to commissioning, system and process-specific safety measures must be observed.
For the media to be transported, the respective safety requirements and measures must be taken into
account.
Prior to using a medium, the compatibility of the materials of the pump head, diaphragm and valves
with the medium must be verified (for materials, see technical data).
The following steps must be carried out for commissioning:
The pumps must not start against pressure or vacuum. When the pump is switched on, the normal
atmospheric pressure must prevail in the pipes. This applies similarly during operation following a
brief interruption of power.
The maximum allowable working pressure (see technical data) must not be exceeded.
Restriction or regulation of the gas flow should only take place in the suction-sided pipe in order to
avoid exceeding the maximum allowable working pressure.
If restriction or regulation of the gas flow takes place on the pressure side, it must be ensured that
the maximum allowable working pressure of the pump is not exceeded.
With the pump stationary, normal atmospheric pressure must be established in the pipes.
Diaphragms and valve plates are the only wearing parts of the pumps. Wear is usually noticeable
by a considerable reduction in pneumatic power. Replacement must take place as described in
chapter 14ff.
Ambient conditions, see technical data.
For pumps used as vacuum pump and compressor:
Pressure and vacuum cannot be produced simultaneously.
The pumps must not be used in areas subject to explosion hazards
or for transporting a potentially explosive medium.
The transported medium must be safely discharged.
When connecting other components to the pump, the pneumatic
conditions must be observed (see 6.).
When connecting the pump to the electrical system, the relevant
safety requirements must be observed.
WARNING!
The standard internal thermal safety cut-out protects the pump
against overload. The pump automatically restarts after cooling
down. Hazardous situations constituted by this must be prevented
by suitable measures.
For the transport of aggressive or toxic media, the system-specific
safety requirements must be observed. Purging with air or inert gas
under atmospheric conditions is recommended prior to
decommissioning.
