5.0 Filter Replacement Procedure
Turn off the feed water at the feed water ball valve. Empty at least 2.0 gallons
from the storage tank to take any back pressure off the system. Put a shallow pan
under the RO system to catch any water that may spill during the operation.
Unscrew the filter housing and carefully lift it to the sink to drain or empty the
water remaining in it. Remove the spent filter cartridge. Sanitize by adding 4 table-
spoons of chlorine bleach to the empty housing and then filling with tap water. Let stand
for 10 minutes. Empty the solution and rinse with clear water and dry. Install new car-
tridge in housing. Reinstall housing being careful to make sure o-ring is properly seat-
ed. Tighten housing securely. Re-start the system by opening the feed water ball valve.
The filter canisters, sediment and carbon, including the the caps must be replaced
every 5 years. Order Vertex part number FH-1000 to obtain original equipment replace-
ment part.
