Step-by-Step Installation Instructions

2. Choose the Installation Location
Install the filter in-line with the vent hose
Position it in an accessible area for future maintenance
Ideally mount it above the tank level to prevent fluid buildup
3. Cut the Vent Hose
Using a hose cutter or knife:
Cut the vent hose at your chosen installation point
Ensure clean, even cuts for a tight seal
4. Attach the Filter
Insert the Nautilus filter between the two hose ends
Use the correct hose barb size (5/8” or 3/4”)
Secure each side using the included hose clamps
👉 Important: Do not overtighten clamps with power tools, as this can damage fittings.
5. Mount the Filter
Secure the unit using the provided screws
Ensure it is stable and properly supported
The filter can be mounted horizontally or vertically
6. Final Check
Ensure all connections are tight
Confirm there are no kinks or low spots in the hose
Test airflow by flushing the system
