2.3 Safety instructions for the operator/
user
The safety instructions described in these
instructions, existing national regulations on health
protection, environmental protection and for accident
prevention and any internal working, operating and
safety regulations of the operator must be observed.
Information attached to the pump must be observed.
Leakages of dangerous substances must be
disposed of in a way that is not harmful to the
personnel or the environment.
Damage caused by electrical energy must be
prevented, see the regulations of the local electricity
supply company.
Before starting work on the pump, the
pump must be disconnected from the
Caution
mains. The system must be
pressureless!
The mains plug is the separator
Note
separating the pump from the mains.
Only original accessories and original spare parts
should be used. Using other parts can result in
exemption from liability for any resulting
consequences.

2.4 Safety of the system in the event of a

failure in the dosing pump

The dosing pump was designed according to the
latest technologies and is carefully manufactured
and tested.
If it fails regardless of this, the safety of the overall
system must be ensured. Use the relevant
monitoring and control functions for this.
Make sure that any chemicals that are
released from the pump or any
damaged lines do not cause damage to
Caution system parts and buildings.
The installation of leak monitoring
solutions and drip trays is
recommended.

2.5 Dosing chemicals

Warning
Before switching the supply voltage
back on, the dosing lines must be
connected in such a way that any
chemicals in the dosing head cannot
spray out and put people at risk.
The dosing medium is pressurized and
can be harmful to health and the
environment.
Warning
When working with chemicals, the
accident prevention regulations
applicable at the installation site
should be applied (e.g. wearing
protective clothing).
Observe the chemical manufacturer's
safety data sheets and safety
instructions when handling chemicals!
Warning
The pump must be equipped with a
diaphragm leakage detection when
used for crystallizing media.
A deaeration hose, which is routed into
Caution
a container, e.g. a drip tray, must be
connected to the deaeration valve.
The dosing medium must be in liquid
aggregate state!
Caution
Observe the freezing and boiling points
of the dosing medium!
The resistance of the parts that come
into contact with the dosing medium,
such as the dosing head, valve ball,
gaskets and lines, depends on the
medium, media temperature and
operating pressure.
Ensure that parts in contact with the
Caution
dosing medium are resistant to the
dosing medium under operating
conditions, see data booklet!
Should you have any questions
regarding the material resistance and
suitability of the pump for specific
dosing media, please contact
Grundfos.
