WARNING!
Operation of the G-BH100 only:

with the pump lid assembled

with the pipes/ hoses connected to
the suction and delivery branches
or

in case of operation with open
suction or delivery branches
(drawing-in of gases from or dis-
charge of gases into the surround-
ings)

with a piece of pipe or hose hav-
ing a length of at least 120 mm
connected to the branch in ques-
tion

with bearing end housing
WARNING!
Do not reach into the G-BH100
through open suction or delivery
branches!
Do not insert any objects into the G-
BH100 through the openings!
i
IMPORTANT!
The G-BH100 must not be operated
with the suction or delivery branches
sealed up or jammed!
WARNING!
Before start-up

check pipes / hoses and vessels
for sufficient strength!

check pipe / hose connections for
tightness!

check fasteners for secure fixing
Proceed as follows:

Make sure
-
that the suction and delivery pipes are cor-
rectly connected,
-
that in case of operation with open suction
or delivery branches (drawing-in of gases
from or discharge of gases into the sur-
roundings)
a piece of pipe or hose
having a length of
at least 120 mm is connected to the
branch in question in order to prevent the
impeller from being reached by fingers.
-
that the suction and delivery pipes are not
jammed,
-
that all fasteners are properly tightened,
-
that the correct voltage and current are
applied.

Set the control voltage serving as speed ref-
erence and applied to n
des
to 0 V at first.

Turn on the indicated operating voltage.
Now increase the control voltage serving as
speed reference and applied to n
des
(0 to
10 V) to your desired value or the value given
on the data sheet. By means of this speed
control the operating point of the G-BH100 is
adapted to the operating point of the system.

Check the connections for tightness (ensure
that there is no fluid leakage).
