WHEN TO CHANGE THE CARTRIDGES
The life of the cartridges depends on the water volume used
and the substances in the water. Normally, cartridges should
be changed at intervals of 12 months. Replace the cartridges
sooner if the water pressure at the application equipment
begins to drop noticeably or if you notice changes in the flow
of the blended water.

The 4FC5 and 4CC Cartridges need to be changed when
replacing the GRO-75EN RO Membrane Cartridge. All
cartridges should be changed at the same time.
NOTE: Only the replacement cartridges listed can be used
with this processor. Failure to use the recommended
replacement cartridges will void your warranty.
1. Place a small pan or towel under the Everpure Conserv
LT-S Processor to catch any water that may drip. Turn
OFF incoming water.
2. Close the ball valve on the the Storage Tank and OPEN
the application equipment valve to relieve pressure.
3. Remove the two (2) cartridges by twisting each cartridge
a 1/4-turn to the left (counterclockwise). Then pull down
to release.
4. Remove the GRO-75EN RO Membrane Cartridge by
removing the tubing from all three (3) connections. Then
pull the cartridge out of the clip.
5. At the bottom of the cartridge, remove the quick-connect
elbow from the red tubing to gain access to the flow
controller and the attached capillary tube. Replace the
flow controller (Figure 13) in the red tubing.
6. Insert a new flow controller (Figure 13) with capillary
tube into the tubing. Replace the quick-connect elbow.
