10 Draining the pump when there is danger of freezing
WARNING
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 motor before drainage.
2. Open valves (covers / plugs) (1,2,3,4,5,6,7,8,9), make sure they are not clogged, clean them if
clogged.
3. Switch the pump on for about 5 minutes to purge the water in the suction and pressure valves.
4. Turn off the engine and close all valves (ports/covers / plugs) after complete water drainage .
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.
