4.1.3 Checking direction of rotation
1. Switch the motor on for some seconds.
2. Make sure the motor turns clockwise (viewed
from the motor fan).
3. If the direction of rotation is wrong, exchange two
phases in the power supply.
4.1.4 Start-up
1. Make sure that the pump is filled properly.
2. Open the threaded connection in the pump
bracket.
3. Open the discharge-side valve.
4. Open the suction-side valve.
5. Switch on the motor and check that it is running
smoothly.
6. Make sure the temperature rises at a rate of no
more than 2 °C/min.
7. Make sure the minimum discharge pressure is
higher than 2 bar.
8. After running at operating pressure and
temperature for a while, check that the pump is
not leaking.
9. Check if the filter system works properly and that
the pump is protected against entrained air, solid
particles and mud.
5. Product introduction
5.1 Intended use
•
Only use the pump for the permissible pumped
liquids. See section
.
•
Make sure the pump is only operated with, and
never without, pumped liquid.
•
Avoid cavitation:
– Open the suction-side valve completely and do
not use it to adjust the flow rate.
– Open the discharge-side valve completely.
•
Avoid damage to the motor:
– Note the maximum permissible number of
starts per hour.
•
Consult the manufacturer about any other use of
the pump.
•
When a pump is supplied without motor, the
pump unit must fulfil the stipulations of the
Machinery Directive, 2006/42/EC.
Observe these instructions in order to avoid
misuse
•
Do not operate the pump outside the operating
limits with regard to temperature, pressure,
viscosity, flow rate and motor speed.
•
Do not operate the pump against closed
discharge-side valve.
•
Do not use the pump for foodstuffs if the pump
has not been adapted accordingly.
•
Only select the installation types described in the
installation and operating instructions:
– do not install the pump hanging in the pipe
– do not install the pump very close to sources of
extreme heat or cold
– do not install the pump too close to a wall.
