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!

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).
