Filter Cartridge Replacement

NOTE: The life of the filter cartridges depends on water
volume used and the quality of the feed water. It is
recommended that the filter cartridges be replaced
every 6-12 months, or when there is a noticeable
change in taste, odor, or flow of filtered water.
Ensure the correct cartridge is purchased for the
system.
Model GRO-350BP uses FDF1-RC, GRO50-RC, and F1GC-RC
Replacement Cartridges
1. Cartridge Replacement
A. Relieve pressure by turning off the water supply to the
system and opening a faucet until water flow stops (wait 5
to 10 minutes after water stops to relieve pressure in RO
membrane). Place a bucket or towel under the system to
catch any water drips.
B. Lift the locking bar upward until the filter cartridge
disengages from the filter head assembly (Figure A).
C. Pull the cartridge away from the filter head assembly and
ensure the locking bar remains in the fully up position
(Figure B).
D. Align the posts on the filter cartridge with the ports in the
filter head assembly. Slide the cartridge filter into the filter
head assembly (engaging with the locking bar causing it to
drop forward and down). (Figure C).
E. Pull down the locking bar until it snaps into place
(Figure D).

Troubleshooting

Leaks between filter head assembly and filter
cartridge
1. Relieve pressure by turning off the water supply to the
system and opening faucet until water flow stops. Place a
bucket or towel under the system to catch any water drips.
2. Remove cartridge and inspect O-rings to make sure they
are seated and clean.
3. Install filter cartridge. Place system into operation and
check for leaks. If leaks persist, turn off the water supply
and contact Technical Support at 1-800-279-9404.
Leaks from tubing fittings
1. Relieve pressure by turning off the water supply to the
system and opening faucet until water flow stops. Place a
bucket or towel under the system to catch any water drips.
2. Depress collet on system or inlet supply adapter tubing
fittings and pull tubing from fitting. Inspect surface of
tubing for scratches or debris. Clean or cut back tubing to
access clean surface.
3. Wet the end of the inlet tubing and press into the inlet
fitting of the system. Ensure the tubing is fully pushed past
the fitting O-rings. Place system into operation and check
for leaks. If leaks persist, turn off the water supply and
contact Technical Support at 1-800-279-9404.
