1. Safety instructions
1.1 Safety instructions for the operator/
user
1.2 Safety of the system in the event of a
failure in the dosing pump
1.3 Diaphragm breakage
Caution
Before starting work on the pump, the
pump must be disconnected from the
power supply. The system must be
pressureless!
Note
The mains plug is the separator separating
the pump from the mains.
Caution
Make sure that any chemicals that are
released from the pump or any damaged
lines do not cause damage to system parts
and buildings.
The installation of leak monitoring
solutions and drip trays is recommended.
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.
Caution
A deaeration hose, which is routed into a
container, e.g. a drip tray, must be
connected to the deaeration valve.
Caution
The dosing medium must be in liquid
aggregate state!
Observe the freezing and boiling points of
the dosing medium!
Caution
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
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.
Warning
Danger of explosion, if dosing liquid has
entered the pump housing!
Operation with damaged diaphragm can
lead to dosing liquid entering the pump
housing.
In case of diaphragm breakage,
immediately separate the pump from the
power supply!
Make sure the pump cannot be put back
into operation by accident!
Dismantle the dosing head without
connecting the pump to the power supply
and make sure no dosing liquid has
entered the pump housing.
Warning
Danger of explosion, if dosing liquid has
entered the pump housing!
Operation with damaged or loose dosing
head screws can lead to dosing liquid
entering the pump housing.
If the pump was operated with damaged or
loose dosing head screws, immediately
separate the pump from the power supply!
Make sure the pump cannot be put back
into operation by accident!
Dismantle the dosing head without
connecting the pump to the power supply
and make sure no dosing liquid has
entered the pump housing.
