Draining the pump when there is danger of freezing
If there is a danger of freezing, a pump used to pump a liquid that may freeze must be drained (while
at a standstill).
1. Turn off the motor.
2. Open valves (covers / plugs) (1,2,3,4,5,6), make sure they are not clogged, clean them if clogged.
WARNING
Make sure that all the drained liquid is contained in a proper manner and disposed
of in accordance with local regulations. Do not simply allow the water to drain onto
the ground, as this could cause the ground to become slippery.
3. Switch the pump on for about 5 minutes to purge the water in the suction and pressure valves.
4. Turn off the motor and close all valves (ports/covers / plugs) after complete water drainage .
