!
Take precautions that in case of leakage no surrounding objects or
environment will be damaged.
!
Install the micro annular gear pump only in places that fulfill the required
conditions for safe pump operation.
!
The motor must be protected against humidity, dust or sweat.
Never install a pump in a small installation location without sufficient
ventilation as the motor will be poorly cooled and can overheat.

General instructions for the assembly of the liquid supply network
!
Please always cut the tubing at a right angle with an adapted hose cutter. If
metal tubes are used, an intensive cleansing procedure will be necessary. After
machining the tubing has to be cleansed and flushed throughoutly. The
smallest piece of swarf within the liquid delivery system may cause failure of
the micro annular gear pump.
!
Please note that correct integration of the tubing with the pump head is a
necessary condition to ensure the right direction of flow. If you wish to
operate the pump in a reverse direction, please contact HNP Mikrosysteme,
since it is not possible in every case.
!
In order to protect the interior of the pump from pollution, the pump heads
are delivered with protective plugs. They should be put on when the pump is
at a standstill.
!
For the best performance the suction tube should be as short as possible and
have a large internal diameter.
Warning
In most cases the pump should be operated with a filter featuring pores that
do not exceed 10 µm. The filter protects the pump from particles and dirt.

Electrical Connections
The electrical connection of the motors must be implemented according to
VDE directives by skilled personnel. The operation manual supplied with the
motors must also be complied with.
Carry out all work on the motor only in no power supply state! Ensure that
there is no supply voltage to the motor
!
Earth the motor using the terminal provided.
Earth the pump head with
heating module additionally at the corresponding terminal clamp.
