The instructions given in paragraph 7.2 "Installation location" and section 9 "Start-up" must be observed before start-up.
1.9 Unauthorized modification and production of spare parts

1.11 Dosing of chemicals
CAUTION!
When working on dosing systems, the local accident prevention regulations must be observed and the specified personal protective equipment must be worn. The
following standard protective clothing is recommended, depending on the hazardousness of the metered medium:
Protective clothing Protective gloves Protective goggles
All persons responsible for assembly and maintenance of piping, hoses and accessories should wear this protective equipment.
Before working on the dosing pump and system, disconnect it from the mains supply and prevent it from being switched on.
CAUTION!
Any chemical still present in the dosing head may spray out when the power supply is reconnected. This may lead to chemical or other burns to the face and
hands. Dosing lines must always be connected before switching on again.
The chemical resistance of the construction materials in the pump must be verified before dosing aggressive media!
The pump dosing head and the system connections and lines may be under pressure. Working on the dosing system requires special safety precautions
and is
allowed only for suitably trained personnel:
CAUTION!
Chemical may spray out. This may lead to chemical or other burns. Always release the pressure before starting work on the dosing pump.
Before working on the dosing head, valves and connections, flush the dosing pump with a harmless medium (water in most cases), to avoid unintentional contact
with the metered medium.
WARNING!
Never look into the open end of a clogged line or valve. Chemical may flow out unexpectedly and cause chemical or other burns to face and hands.
Before start-up, all screw connections must be inspected for correct tightness and leak-tightness, and must be re-tightened using an appropriate tool if necessary.
