Air intake filter
To ensure proper cooling of the instrument, the air filter must be cleaned or replaced
every three months (Part Number 29381).
1
Open the filter cover located on the rear
panel. Remove the air filter.
2
Clean or replace the filter. Shake the filter a
few times to loosen trapped dust and return it to
the instrument. If you soak the filter in soapy water
to clean it, always allow it to dry completely before
returning it to the instrument, as moisture will cause
damage to the internal parts. For replacement filters,
call Zeiss Humphrey Systems Parts Department.
3
Close the filter cover.
Floppy disk drive
All HFA II models are equipped with a 3.5" floppy disk drive for data storage. How often
you clean the disk drive depends on how frequently you use it. One suggestion is to clean the
drive every six months. Head cleaning kits may usually be purchased from electronic or
computer stores.
