non-abrasive cloth or sponge. Do not spill liquid inside

Cleaning or Replacing the Filters (3 Types)
Clean or replace the lters as often as specied in the
following paragraphs in order to protect the compressor
and extend the concentrator’s life. Replacement lters are
available from your Graham-Field equipment provider.
Bottom filter
The bottom lter does not typically require cleaning, but
it may if operated in extremely dirty conditions. Perform a
visual inspection of the bottom lter every 2 weeks; if the
lter is dirty, clean it. The bottom lter is located at the
bottom rear of the cabinet (see Figure 1). To clean:
1. Remove the bottom lter
from the squares carefully
with your ngers.
2. Inspect the lter; if any part
of it is cracked or broken,
replace it instead of clean-
ing it.
3. If cleaning, rinse lter well
with clear water until all dirt is removed.
4. Dry lter by squeezing between two absorbent towels.
Wait for filter to dry. When dry, install lter carefully as
shown in Figure 1.
