Dräger SAM 3100/3200 aspirator system:
The aspirator system is designed so as to minimise the need
for servicing.
 Directions for maintenance and servicing can be found in
the Instructions for Use for the components used.
 Depending on the dust load in the sample gas, the filter
inserts should be replaced when visibly soiled. Spare parts:
see the Instructions for Use for the filter.
 In the case of systems with gas sampling pump, it is
recommended that the diaphragm and valve plates of the
pump are replaced at least once a year.
 Spare parts: refer to the Instructions for Use for the gas
sampling pump.
 The ejectors for delivering sample gas have no mechanical
parts subject to wear, and are therefore maintenance-free.
Gas transmitter
 Maintenance and servicing of the gas transmitter should be
carried out according to the enclosed Instructions for Use.
 The calibration interval and calibration instructions can be
found in the Instructions for Use for the gas transmitter and
for the DrägerSensor.
 For aspirator systems with gas sampling pump, the pump
should be switched off during test gas feeding (calibrating).
For models with ejector, the air feed should likewise
be interrupted.
