 WARNING
Danger of burns and scalding from hot
surfaces of the installed unit and from hot
fluids!
Only operate the system with the protective
screen and cover plate installed!
Allow to cool after shut-down!
 WARNING
Improper use of the system can result in
serious or even fatal injuries!!
 Do not reach into the installed unit through
the opened intake or discharge connection!
 Do not insert objects into the installed unit
through the openings!
 WARNING
Danger from tipping or falling loads!
If the system is installed on moveable machine
parts or at a great height without any other
protection against falling, the following applies:
 If the screw connection to the installation
surface is unscrewed for maintenance
work, then the system must be placed on a
flat, rigid (stationary) surface.
 If appropriate, secure the system against
falling from a great height.
 WARNING
Improper use of the system can result in
serious or even fatal injuries!!
Do not disassemble unless the system has
been shut down and come to a complete
standstill!
Consider that the system has a certain run-out!
Only restart when the following conditions are
met:
 The system is completely assembled.
 The pipe/hose connections, pipes/hoses
and vessels have been checked for
sufficient strength, freedom from leaks and
secure seating!
 The fasteners have been checked for
secure seating!
NOTE
For the system design, see Fig. 1, Pg. 3. The
item numbers (Item) specified in the text refer
to this illustration.
9.1 Maintenance
The system is largely maintenance-free.
The following maintenance work is necessary:
 If limy water is used as the operating liquid,
the operating liquid must be softened or the
entire system and the installed unit must be
decalcified at regular intervals.
 Check the hoses and hose connections for
any leaks and for firm seating!
 If dirt or solid materials (e.g. dust or sand) of
lime deposits enter the system through the
operating liquid and/or the pumped
gases/vapours, it must be cleaned at regular
intervals. This will prevent impeller jamming
as well as the wear of individual system
components.
