Aquathin PEARL 30 Getting Started page 33

Replacing the Aquathin Sediment Pre-filter
The sediment pre-filter is in the canister on the left side
of the assembly. The sediment pre-filter will likely be
distasteful looking—it is common for sludge to form on
the filter surface. After one year, this sludge layer can be
fairly thick. The good news is, if the sediment filter and
the PEARL did not
catch this "guck",
your body would !!
a) Push the red
button (on the
top of the
a l u m i n u m
frame, above the
p r e - f i l t e r
c a n i s t e r ) t o
reduce any back
pressure remaining in the canister.
b) Firmly grasp the canister with both hands and
unscrew it from the pre-filter assembly. (A canister
wrench is included.) Carefully move the canister
over the bucket, dump the water, and remove the old
pre-filter.
c) Using a long handled, soft bristle brush, scrub the
inside of the canister with a mild dish washing
detergent and rinse.
d) Place the new pre-filter into the canister, and then
carefully re-attach the canister to the assembly.
Tighten until firm.
Replacing the Aquathin Carbon Pre-filters
The Aquathin carbon pre-filters are in the middle canister
and the canister on the right. Follow the same procedure
as described for replacing the sediment pre-filter (above).
