Danger
•
The main circuit of the pump type SR25.1, SR25.1/EX and SR25.2-G must be equipped with a fuse (0.25 A
recommended) corresponding to the nominal current (over current protection EN 60335-1);

The pump must be installed so that contact with alive parts (connections, possibly windings) is impossible.
PREPARATIONS FOR COMMISSIONING
12
Before initial startup, all plant- and process-specific safety measures must be observed. It is mandatory for the
operator to complete the enclosed risk assessment of the product.
The gas exposure risk must be assessed by the operator with regard to the hazards posed by process and calibration
gas and the setup at the installation site (e.g. tubing, system cabinet/container/plant). If the risk assessment reveals
increased exposure hazards, further measures are required.
A visible label must be attached to the installation site in accordance with the risk assessment provided by the
operator.
START-UP
13
Specific safety instructions for media being handled must be observed. Before pumping a medium, the
compatibility of the flexible tube material with the medium must be checked. The following steps should be carried
out before initial start-up:
•
The maximum permissible operating pressure (see technical data) must not be exceeded, even when the
flow is restricted.
•
Ambient conditions: see technical data.
