Note:
• All cables used must be heat-resistant up to
at least +85 °C.
• All cables used must be installed in accordance
with EN 60204-1.
Concerning demands on signal wires and signal
transmitters, see section 12. Technical data.
6. Start-up
Do not start the pump until the system has been filled
with liquid and vented. Furthermore, the required
minimum inlet pressure must be available at the
pump inlet. See section 12. Technical data.
6.1 Venting the pump
Vent the pump before start-up. See fig. 7.
Fig. 7 Venting the pump
The pump may be noisy, when first switched on,
due to air remaining in the pump. This noise should
cease after a few minutes running.
After start-up, set the desired operating mode and
possibly pump head.

Warning
Wires connected to
• outputs 7 and 8,
• inputs 1 to 6,
• supply terminals and
• differential-pressure and
temperature sensor
must be separated from each other and
from the supply by reinforced
insulation.
All wires connected to a terminal block
must be tied up at the terminals.
The system cannot be vented through
the pump.
Warning
When the vent screw is slackened,
scalding hot liquid under high pressure
may escape. Care must be taken to
ensure that the escaping liquid does
not cause personal injury or damage to
other components.
