PERIODIC MAINTENANCE
The only element of the FEP unit requiring periodic maintenance is the air filter, located on the left hand
side of the unit. The filter should be replaced or cleaned every 12 months in normal operating environ-
ments. It should be replaced more often in dusty environments.
The replacement of air filter or fan can be done without turning off the power supplies. The fan and air
filter assembly is located on the left hand side of the FEP unit. Replacement filters can be purchased
from Cyclone Microsystems, Cyclone part number 370-1303.
