Note!
If several pumps are included in the system, make
sure you know which one should be stopped
fi rst.
1. Slowly reduce the fl ow rate in order to avoid water hammer.
2. When the valve is closed, stop the pump.
3. Repeat steps 1–2 for the other medium/media.
4. If the plate heat exchanger is shut down for a long period, it
should be drained.
Also, drain the heat exchanger if the process is shut
down and the ambient temperature is below the freezing
temperature of the media.
Depending on the media processed, rinse and dry the heat
exchanger and its connections.
