Thermal switch/PTC thermistor
sensor
The motors are equipped as standard with a thermal switch (capaci-
tor motor) or with PTC thermistor sensor (three-phase motor) to
monitor against overheating (see operating instructions for the mo-
tor).

Highest permissible relative air hu-
midity of the environment 80% for temperatures to 31°C, de-
creasing linearly to 50% at 40°C
(non-condensing).
Maximum installation altitude [m
above sea level] See operating instructions for drive
Protection class of pump IP20
Noise**** Max. 70-80 dB (A)
Tab.16 *To reduce the surface temperature of the pump heads and to extend the
service life of the diaphragm, you can optionally attach a water cooling system (see
Chapter 6.5 Connecting water cooling (optional)).
**The gas tightness of the pump head is no longer ensured after the pump head is
opened or after the diaphragm and reed valves are changed. A leak test can be
used to determine whether the original gas tightness is achieved again.
***Values apply to helium leak test
****Max. emission sound pressure level over the entire pressure range with gas
connections attached
Start-up against pressure/
vacuum
