12. Startup
Before you start the UPM3 pump:
1. Mount the pump in the right way.
2. Check that the unions are tightened.
3. Check that the valves are opened.
4. Fill the system and vent it above the pump.
5. Check if the required minimum inlet pressure is
available at the pump inlet.
6. Switch on the power supply.
7. If the pump is externally controlled: Check if the
external controller sends a signal that controls the
speed or that might have stopped the pump.
8. If the pump is internally controlled: The pump starts
with factory pre-setting (e.g. proportional pressure
curve 3). Change the setting if necessary (see
Overview of operating panel control modes).
Do not start the pump until the system has been filled
with liquid and vented.
UPM3 pumps are self-venting and do not have to be
vented before startup. Air inside the pump is
transported by the liquid into the system shortly after
startup.
Hint for installers:
• Heating systems must be flushed according to local
standards, such as DIN EN 14336 or VOB ATV C DIN
18380, before startup. After filling the system for the
first time, the pump must run for approx. 1 hour
before a long-term stop.
• Inhibitors and additives increase the risk of
malfunction of the pump.
• If filters are installed, they must be monitored and
maintained thoroughly.
