water through the sediment filter and into the bucket. Allow the water to flush through
the filter for 3min, which in most cases will be about 2-3 gallons. Shut off the ¼-turn
valve.
4. Remove the sediment filter by turning it counter-clockwise. *ONCE REMOVED, BE SURE
TO NOT LOSE THE TWO BLACK O-RINGS INSIDE THE TOP OF THE FILTER.
5. Remove the Pre-Carbon Filter and the Post-Carbon Filter the same way.
6. Install the Pre-Carbon Filter into Filter Head #1 (see below). With the flush tube still
running to drain, open the ¼-turn valve and allow water to flush the filter for 3 min.
Once complete, shut the ¼-turn valve off.
