5 MAINTENANCE
5.3 Maintenance on the purge air supply
Maintenance work to be carried out:
● Inspecting the entire purge air supply
● Cleaning the filter housing
● Replacing the filter element, if necessary.
The dust load and wear on the filter element depend on the degree of contamination of the
intake ambient air. It is therefore not possible to specify precise time intervals for these
tasks. We recommend inspecting the purge air supply at short intervals (approx. 2 weeks)
and then optimizing maintenance intervals over a longer period of operation.
Inspection
▸ Check the running noise of the blower at regular intervals; increases in the noise level
c
an indicate a blower failure.
▸ Check that all hoses are secure and free of damage.
▸ Check the filter element for contamination.
▸ Exchange the filter element when:
– Severe contamination (deposits on the filter surface) is
visible
–
The purge air volume is reduced considerably as compared to operation with a ne
w
fil
ter.
NOTE:
Irregular or insufficient maintenance of the purge air supply can cause it to fail and thus
cause severe damage to the sender/receiver unit.
▸ Always ensure the purge air supply when the optical component sender/receiver unit
is fitted on the duct.
▸ Disassemble the connected components before exchanging damaged purge air
hoses (see “Shutdown”, page 57).
The purge air supply does not have to be switched off to clean the filter housing or
to replace the filter element, i.e. the components can remain on the duct.
