MAINTENANCE

With minimal but important maintenance, the F6-DP can provide many seasons of reliable
service� After each use, clean the F6-DP with a damp cloth to remove dirt and oils�
Do not use gasoline or other hazardous solvents to clean F6-DP; this can damage the
plastic enclosure� Standard household detergent or isopropyl alcohol may be used, but
do not allow liquid to penetrate the outer case�
Make sure the inlet and discharge ports are protected during transit and storage; keep the
inner diameter and the outer threads clear and clean�
NOTE: For best results, leave the filter connected to the inlet port,
