Basic Safety Instructions
2.1 General
Information
Warning notices must be observed. Disregarding them may lead to damage to health and
property.
The diaphragm pumps must be operated by personnel who can detect impending dangers
and take action to prevent them from materialising.
The manufacturer or authorized authorised workshops will only service or maintain the dia-
phragm pump if it is accompanied by a fully completed damage report. Precise information
about the contamination (also negative information if necessary) and thorough cleaning of
the diaphragm pump are legally binding parts of the contract.
Contaminated diaphragm pumps and their individual parts must be disposed of in accor-
dance with the legal regulations.
The local regulations apply in foreign countries.
2.2 Electricity
The diaphragm pumps of operation mode S1 are supplied. When the location of operation
mode S1 devices is changed, please note that the testing must be repeated in accordance
with DIN EN 0105, DIN EN 0702 and BGV A2.
The local regulations apply in foreign countries.
Please note the following when connecting to the electrical power supply system:
•
The electrical power supply system must have a protective connector according to DIN VDE 0100-
410 (IEC 60364-4-41).
•
The protective connector must not have any breaks.
•
The connecting cable must not be damaged.
2.3 Mechanical
Systems
Improper use can lead to injuries or material damage. Observe the following instructions:
•
Only operate the diaphragm pumps with hoses of the specified dimensions.
•
The maximum permissible pressure of 1 bar at the suction connection must not be exceeded.
•
Hazardous substances must be separated out as far as this is technically possible before they
reach the pump.
•
External mechanical stresses and vibrations must not be transmitted to the pump. Only use flexible
NW 8 laboratory hoses for connecting diaphragm pumps.
•
The overpressure generated at the pressure port must not exceed 1 bar.
•
The pump must not be used to suck up fluids. Lay the exhaust pipe so that it slopes downwards, so
allowing condensate to flow out of the pump. Collect the condensate and dispose of it in an envi-
ronmentally compatible manner.
•
Prevent dyes exuding.
•
Maintain a space of least 20 mm between the pump and adjacent parts in order to enable the pump
to cool.
CAUTION !
Solid particles in the pumping medium impair the pumping action and can lead to
damage. Prevent solid particles penetrating into the pump.
