6.8 Cleaning the purge air unit
The filter of the purge air unit must be exchanged at the latest when the low-pressure mon-
itor on the filter outlet triggers.
Preparation
▸ If the purge air unit is not immediately functional again: Remove the SR-unit and reflec-
tor unit from the gas duct (swiveling out is sufficient for short-time work).
Procedure
1 Put the purge air unit out of operation and completely remove the purge air hoses.
2 Replace the air filter in the purge air unit and clean the inside of the purge air unit.
3 Fully swivel out the SR-unit and the reflector so that dust which was possibly blown
through the purge air hose is not deposited on the windows.
4 Put the purge air unit back into operation, see “Start-up of the purge air supply”, page
35.
NOTE:
Replacement of the sender lamp is identical for all GM32 variants.
NOTE: Inadequate purge air supply can damage the gas analyzer.
▸ The purge air unit must be in perfect condition.
