Check pipes/hoses and vessels for
sufficient strength!
Check pipe / hose connections for
tightness!
Operation of the G-BH100 only when
completely assembled and securely
fastened to the mounting surface!
Check fasteners for secure fixing at
regular intervals!
After loosening clampings and fas-
tening elements some parts and
components are only held in place
by their centrings or seatings or are
no longer held in place at all so that
they might fall down.

WARNING!
In case of operation with open suc-
tion or delivery branches (drawing-in
of gases from or discharge of gases
into the surroundings) a piece of
pipe or hose with a length of at
least 120 mm must by all means be
connected to the branch in question
in order to prevent the impeller from
being reached by fingers!

The electrical connections must be
surrounded by a housing which is
proof against foreign bodies, humid-
ity, etc.!
Consider the life expectancy of the
seals and gaskets!
Ensure that no foreign bodies, hu-
midity, etc. enter the motor interior!
For heat dissipation and cooling pro-
vide a minimum distance of 15 mm
on each side except for the pump lid
side on which a smaller distance of
at least 2 mm is permissible!
