2. Remove the silicone tubes attached to each end of the filter body.
3. Install a new filter by pushing each tube completely over the barb on the filter body. Verify
flow direction is correct.

or kinked upon completion of the installation or the unit will alarm for low oxygen purity
after the warm-up cycle is complete.
