and follow these instructions during operation.
1. The pump may only be operated in an upright posi-
tion.
2. Ensure that the pump is resistant to the medium
being pumped.
3. Note the limit values for temperature, viscosity and
density of the medium being pumped.
4. The motor must rotate in the direction indicated by
the arrow (B70V).
5. Ensure that all connections and ttings are properly
tightened.
6. Ensure that the motor is switched o before con-
necting to the electricity supply.
7. The drive motor must be located outside the mobile
container or drum.

Zone 0 IIA T4.
2. Only use PTFE stators and stator sleeves marked
with PTB-No. for ammable liquids.
3. Only use explosion proof drive motors.
4. Electric connection in explosion hazard areas only
with explosion proof plug or explosion proof termi-
nal box.
5. Connect the equipotential bonding between pump
tube and container before starting operation.
6. Use conductive pressure hoses and conductive hose
connections.
7. The drum pump must not be employed for non-
mobile operation.
8. The pump must not be left unattended while in op-
