• Ensure that no parts of your clothing, hair or fingers
can be caught or drawn in at the inlet of the pump.
Never insert fingers or drop any other object into the
inlet or outlet.
• You must take suitable precautions to prevent any
dangerous situation from arising if the controller starts
a NT VARIO pump, switches a coolant valve or opens
a venting valve.
• Attention: If the controller is set to Autostart, the pro-
cess will start immediately after a power failure with-
out pressing any further key. It is your responsibility to
ensure that automatic start-up of the system will not
lead to any dangerous condition. Provide appropriate
safety measures. Check prior to starting the process
whether the option ”Autostart” (menu: configuration) is
enabled.
• Pay attention to the safety symbol ”hot surfaces” on
the equipment. Hot parts may cause burns if touched.
Adopt suitable measures to prevent any danger aris-
ing from hot surfaces or electric sparks. Ensure that
hot surfaces of the pump do not cause burns. Provide
a suitable contact guard if necessary.
Prevent the backpressure of gases and the backflow of
condensates at the outlet.
Provide appropriate protective measures to allow for the
possibility of failure and malfunction. The protective mea-
sures must also allow for the requirements of the respec-
tive application.
In case of overload, the motor is shut down by a self-hold
thermal cutout in the winding.
Note: Only manual reset is possible. Press the START/
STOP key at the controller to confirm the error message.
Switch off the pump and disconnect from the power source.
Identify and eliminate the cause of failure. Allow the pump
to cool down sufficiently before restart.
