Pro Tip
When servicing your FNS Plus filter, inspect all wing nuts for signs of corrosion or thread damage before reassembly. If any nut shows resistance when hand-tightening or visible pitting on the threads, replace it at this service interval a failed fastener during operation can compromise filter pressure integrity. Ordering a spare at the same time as your grid service kit is a practical precaution.
