Close the shut-off device in the discharge line.
NOTICE
If a non-return valve is installed in the discharge line, and there is coun-
terpressure, the shut-off device can remain open.
CAUTION
Risk of damage due to incorrect handling!
When switching off the pump, the shut-off device in the inlet pipe must
not be closed.
Switch off the motor and allow it to coast down completely. Ensure the coasting is
smooth.
For longer downtimes, close the shut-off device in the inlet pipe.
For longer periods of non-use and/or danger of freezing, drain the pump and secure it
against freezing.
After removing the pump, store it in a dry and dust-free place.
NOTICE
The pump must always run smoothly and vibration-free and must not be
operated in conditions other than those specified in the catalogue/data
sheet.
DANGER
Danger of death due to lack of protective devices!
Due to missing protective devices of the terminal box or near the coup-
ling/motor, electric shock or contact with rotating parts can lead to life-
threatening injuries.
• Immediately after the conclusion of all work, all the provided safety
and protection equipment items must be properly installed and put
into operation!
WARNING
There is a risk of burns or freezing upon coming into contact
with the pump/system.
Depending on the pump and system operating conditions (fluid temper-
ature), the entire pump can become very hot or very cold.
• Keep a safe distance during operation!
• Allow the system and pump to cool down to room temperature!
• Always wear protective clothing, safety gloves and safety glasses
when working.
The pump can be switched on and off in different ways. This depends on the different op-
erating conditions and the degree of automation of the installation. Observe the following
points:
Stop procedure:
Prevent return flow to the pump.
Do not operate for too long with the volume flow being too low.
Start procedure:
Make sure that the pump is completely filled up.
Ensure a continual flow to the pump with a sufficiently large NPSH.
Avoid that insufficient counter pressure leads to a motor overload.
