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 engine and open canopy draining ports (covers / plugs) (1).
2. Make sure the canopy draining ports (covers / plugs) (1) are not clogged with solids, clean them if clogged.
3. Open valves (covers / plugs) (2,3,4,5,6,7,8,9, 10), make sure they are not clogged, clean them if clogged.
4. Turn the engine on for 5 min after opening all valves (covers / plugs) to ensure complete water drainage.
5. 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.
1. When all valves and covers are opened switch the pump on for about 5 minutes to purge the water
in the suction and pressure valves. Keep safe distance from pump in this operation.
2. Turn off the engine and close all valves and covers after complete water drainage.
