Safety Instructions For The Operator/User; Safety Of The System In The Event Of A Failure In The Dosing Pump; Dosing Chemicals - Grundfos DME Serie Instrucciones De Instalación Y Funcionamiento

Risks of not observing the safety instructions
Non-observance of the safety instructions may have
dangerous consequences for the personnel, the
environment and the pump and may result in the loss
of any claims for damages.
It may lead to the following hazards:
• Personal injury from exposure to electrical,
mechanical and chemical influences.
• Damage to the environment and personal injury
from leakage of harmful substances.
1.3 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
power supply. The system must be
pressureless!
The mains plug is the separator separating
Note
the pump from the mains.
Only orginal accessories and original spare parts
should be used. Using other parts can result in
exemption from liability for any resulting
consequences.
1.4 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 system parts
Caution
and buildings.
The installation of leak monitoring
solutions and drip trays is recommended.

1.5 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 pressurised 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 crystallising media.
A deaeration hose, which is routed into a
container, e.g. a drip tray, must be
Caution
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
dosing medium are resistant to the dosing
Caution
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
