WARNING!
Risk of injury due to pressure safety valve!
–
The pressure safety valve is under pressure, do not touch.
–
The pressure safety valves are configured and may not be
changed.
–
Ensure that the factory setting of the pressure safety valve com-
plies with the requirements of the pump.
It is possible that the centre height of the drive shaft may change as
a result of heating up. In this case, the pump unit must be realigned
Chapter 5.5 ‘Aligning the pump unit’ on page 32).
1.
Lay connections and install heating/cooling in the properly manner (
manufacturer's instructions).
2.
Check technical data for the heating/cooling medium (
job data sheet).
3.
Bleed heating/cooling.
4.
For heating/cooling, ensure:
n
Required parameters (
system documentation, pump data sheet,
dimensional drawing)
n
Temperature difference between heating medium and conveyed
medium less than 50 °C
n
Switch on pump heating at least 2 h before commissioning.
1.
Ascertain the appropriate oil lubrication system (
pump data sheet).
2.
Install oil lubrication system (
