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 returning all parts must be completely free of chemicals! We
would like to point out that only clean, rinsed and chemical-free parts
can be accepted by our service!
This is the only way to exclude the risk of injury to our staff from residual
chemical products. The goods sent in must, as it is possible, be additionally
packed in a suitable bag that prevents residual moisture from leaking into the
outer packaging. Enclose a copy of the product data sheet of the chemical
used so that our service staff can prepare for the use of the necessary
protective equipment (PPE).
