13 START UP
Before starting up, please observe the safety measures related to the installation and the process!
Also respect the respective safety prescriptions and measures related to the sampled gases. Before
pumping the medium, please check the compatibility of the gas with the materials of pump head,
diaphragm and valves (for pump materials: see technical data).
The following steps have to be executed for the initial start up:

The pump must not start against pressure or vacuum.

When switching on the pump, the pressure in the lines must be atmospheric. The same is
valid when the pump is restarted after a power cut off for a short period.

The maximum permissible operating pressure (see technical data, chapter 9) must not be ex-
ceeded.

To prevent the maximum permissible operating pressure being exceeded, restriction or control
of the gas flow should only be carried out in the suction line.

If restriction or control of gas flow is made on the pressure side, ensure that the maximum
permissible operating pressure is not exceeded.

When the pump is at a standstill, the lines must have got the normal atmospheric pressure.

Diaphragm and valve plates are the only parts subject to wear. Wear is usually indicated by a
drastic reduction in the pneumatic performance. When replacing parts, proceed as described
in chapter 15.

Ambient conditions: see technical data, chapter 9.
14 CLOSING DOWN
N O T E !
The location where the pump is installed must be free of frost also
when it is not in use.
No special measures are to be taken when closing down the pump.
W A R N I N G !
Aggressive condensate possible.
Wear safety glasses and appropriate protection clothes when
dismounting, repairing or cleaning the pump!
