NOTICE!
Damage caused by using incorrect tools!
Damage may occur as a result of using incorrect tools during assembly,
maintenance or troubleshooting. Only use the correct tools.
DANGER!
– Always use the prescribed PPE for maintenance work.
Observe the product data sheet of the dosing chemical used.
– Always flush the dosing head and relieve the pressure line.
DANGER!
– Electrical repairs may only be carried out by qualified electricians in
accordance with local regulations!
– Before any adjustment, maintenance work, repair work or exchange of
parts, the device must be disconnected from all sources of power if opening
of the device is necessary.
– Live parts may be exposed when opening covers or removing parts
(apart from covers that can be opened or parts that can be removed without
using tools). Connection points may also be live.
DANGER!
Conditions for returns
Before being returned, all parts must be completely free of all chemicals!
We would point out that only clean, rinsed parts that are free of all
chemicals can be accepted by our service!
This is the only way of excluding the possibility of the risk of injury to our staff
due to residues of chemical products. The goods sent in must, where possible,
also be packed in a suitable bag preventing any leakage of liquid residues into
the surrounding packaging. Enclose a copy of the product data sheet for the
chemical used so that our Service staff can be prepared to use the necessary
personal protective equipment (PPE).
