WARNING!
Danger from chemical residues
There is normally chemical residue in the liquid end and on
the housing after operation. This chemical residue could be
hazardous to people.
– It is mandatory that the safety notes in the "Storage,
Transport and Unpacking" chapter are read before ship‐
ping or transport.
–
Thoroughly clean the liquid end and the housing of
chemicals and dirt. Adhere to the material safety data
sheet for the feed chemical.
WARNING!
Warning of dangerous or unknown feed chemical
Should a dangerous or unknown feed chemical be used: It
may escape from the hydraulic components when working
on the pump.
– Take appropriate protective measures before working on
the pump (e.g. safety glasses, safety gloves, ...).
Observe the safety data sheet for the feed chemical.
–
Drain and flush the liquid end before working on the
pump.
WARNING!
Fire hazard with flammable media
Only with combustible media: These may start to burn when
combined with oxygen.
– During filling and draining of the liquid end, an expert
must ensure that feed chemical does not come into con‐
tact with oxygen.
CAUTION!
Warning of feed chemical spraying around
Feed chemical can spray out of the hydraulic components if
they are manipulated or opened due to pressure in the liquid
end and adjacent parts of the system.
– Disconnect the pump from the mains power supply and
ensure that it cannot be switched on again by unauthor‐
ised persons.
–
Depressurise the system before commencing any work
on hydraulic parts.
Danger of damage to the device
Take into account the information in the "Storage, Transport
and Unpacking" chapter if the system is decommissioned for
a temporary period.
1. Disconnect the pump from the mains power supply.
2. Drain the liquid end by turning the pump upside down and allowing
the feed chemical to run out.
