•
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 arising
from hot surfaces or electric sparks. Ensure that hot
surfaces of the pump do not cause burns. Provide a
suitable contact guard if necessary.
• Ensure that the
coolant outlet pipe
at the waste vapor
condenser is always free and that it cannot get blocked.
Prevent the backpressure of gases and the backflow of
condensates at the outlet.
Check the liquid level in the collecting flask regularly and
drain condensate in time to prevent overfilling.
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. Switch off the pump
and disconnect from the power source. Identify and elimi-
nate the cause of failure. Allow the pump to cool down suf-
ficiently before restart. Wait approx. five minutes before
restarting the pump.
Maintenance and repair
In order to comply with laws (occupational, health and
safety regulations, safety at work law and regulations for
environmental protection) vacuum pumps, components
and measuring instruments can only be returned when
certain procedures (see section „Repair - Maintenance -
Return - Calibration“, pg. 42) are followed.
