Maintenance Instructions
1. Quick couplings; it is recommended to lubricate
all couplings parts regularly, approx. once a

and damage of o-rings.
2. If the quick couplings leak, o-rings should be
replaced.
3. Depending on usage, maintenance should be
undertaken by an authorised service engineer at
least once a year in order to prevent defects and
failure of operation. Authorised engineers are
persons who due to their skills and experience
have sufficient knowledge of Hygiene Systems
and are confident with the state work safety regu-
lations, accident preventing regulations, lines and
generally acknowledged technical regulations
such as DIN-norms and VDE-provisions. For
your safety, this cleaning unit has been manufac-
tured according to all relevant regulations valid
in the EU and therefore it has been supplied with
the CE-marking. For further information, please
refer to the service department.

until the injector has been rinsed through (approx.
30 seconds).
• Remove the suction hose from the water can.
7. It is recommended to descale the unit according
to pharagraph 9.5
8. It is recommended to clean the surface inside the
unit at least once a month in order to maintain
parts and avoid corrosion of parts.
8. Operation
