The aluminum is soft and you can drill through it without much trouble with a normal wood bit. *Optional for normal operation if you want to run inline this step is needed. STEP 1: Put Stocking on cups from so the open and closed ends match. IE put cup bottom first into stocking. STEP 2: Fill 14oz (half of the 28 oz bottle) into each larger through stocking hole or pulled back split evenly. STEP 3: Secure outside stocking over rim to the inside cup. And Flip over with hand over top and gently twist and shake and tip back and forth a couple times to even it and secure it hold upside (you want all the carbon towards open end and leave space on the bottom. STEP 4: Finish off the stocking pull inside stocking out of the middle cup until it starts to clear the edge pull from end and secure. STEP 5: Attach to 4" Fan or to fitting For Use on a Hood See Below (Pulling Air, when you can vent to outdoors generally) You want order to be Carbon on Hood Then Fan Then Exhaust in that order. For Exhaust Installation See Below (You Would use this if you can't vent to outside and are venting in your house etc, as this will mask the most smell but reduces airflow more than having it on intake) For Inline Installation** **You must use the tapered outer pencil holder for it to fit inside the 4" tube.
