4.2 Final Filter Replacement
The final filter should be replaced each time the activated carbon/alumina is changed. The
filter is located immediately after the outlet of the CO catalyst canister.
1. Remove the four (4) panel screws using a 1/8” Allen wrench
and pull the top panel out. Note the position of the filter so
that you can install the replacement in the same way.
2. Loosen the 1/4” compression nuts on either end and pull the
filter from the tubing.
3. Remove the nuts from the old filter and place them on the
new filter.
4. Install the new filter with the standoff end (visible inside the
housing, supporting the filter element) connected to the
catalyst canister outlet.
5. Firmly tighten the compression nuts on the inlet and outlet
tubing.

1. Disconnect the power cord from the power input module
on the bottom panel of the unit.
2. Using a slotted tip screwdriver, pry up at the slot located
about ¼” below the surface of the power input module,
inside the cord entry socket. This will pull up the fuse
carrier that holds the fuse on the bottom and a spare.
3. Inspect the fuse to see if it is blown. If so, remove it and
replace it with the spare fuse.
4. If the fuse is in good shape, re-install and plug the system
back in.

screws located on the corners of the bottom panel. Pull the bottom panel out and inspect
