Check sieve in exhaust air duct for soiling; remove off-gas line for
this purpose.
Every 6 months
Perform calibration (at shorter intervals depending on accuracy
requirements).
As required
Check hose connection to the density measuring cell/sensors for
porosity.
Every 6 months

Check seal of housing for functioning and damage.
Each time the doors
are opened
Check compressed air filter for soiling/blockage/condensate,
optionally installed by owner.
As required
Check compressed air inlets/outlets for soiling (oil, dust etc.) and
corrosion, have cleaned by manufacturer.
As required
Check compressed air inlets/outlets on/in housing for soiling (oil,
dust etc.) and corrosion.

Flow plates are attached on the side of the thermoelectric battery and in the thermal elements of the
combustion calorimeter. The flow plates must not be twisted when removing the thermoelectric
battery. The thermoelectric battery must be pulled out as far as possible and then tilted to the side.
3
Cleaning of the heat exchanger with water followed by thorough drying.
4
Clean the nozzles using a volatile solvent.
