level.

Risk of material damage due to frost!
If there is a danger of frost:
• Drain the pump completely to avoid damage.

Close the shut-off device in the pressure pipe. If a non-return valve is installed in
the pressure pipe and counterpressure is present, the shut-off device can remain
open.

If there is no danger of frost, make sure the fluid level is sufficient.
