tions for the pumped medium valid at the place of installation
as well as internal working-, operating-, and safety instructions
of the owner are to be observed.

drained off so that a risk to persons and the environment can
be excluded. The legal regulations are to be adhered to.
Dangers caused by electrical energy are to be prevented.
3.7
Safety instructions for maintenance,
inspection and installation
The operator has to ensure that all maintenance, inspection
and installation tasks are carried out by authorized and

ing instructions.
3.10 Proper use
The
sera
diaphragm pump is only to be deployed according to
the intended purpose stated in the product description and the

pump is appropriately used are:
•
Characteristics of the medium conveyed (refer to the
safety and product data sheet of the used medium – the
safety data sheet is to be provided by the supplier /
operator of the conveying medium).
•
Stability of the materials which have contact with the
medium conveyed
•
Operating conditions at the place of installation
•
Pressure and temperature of the conveying and cooling
medium
•
Voltage supply
3.11 Personal protection for service and
maintenance
In order to avoid risks to health, the provisions of the German
Ordinance on Hazardous Substances (GefStoffV) (§14 Safety
Data Sheet) and relevant national safety regulations for the
dosing medium must strictly be adhered to.
In case of accidents check whether the following substances
are emitted:
•
Leakage of fluids
•
Leakage of fumes
•
Noise emissions (sound level)
Emissions must be monitored by monitoring systems of the
total installation.
CAUTION!
Use protective clothing, gloves, breathing mask and
suitable goggles for face protection!
CAUTION!
Personal protective equipment must be provided by the
equipment operator at all times!
