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. Acknowledge the er-
ror message at the controller. Switch off the pump and
disconnect from the power source. Identify and eliminate
the cause of failure. Wait approx. five minutes before re
-
starting the pump.
