Replacement Cartridges - Pentair EVERPURE CONSERV 75E EV9977-00 Original Instructions Manual

The Conserv 75E System includes a blend system that can
combine or "blend" water sources. OPENING the blend
adjustment valve will add untreated water with higher TDS to
the water.
To achieve the target TDS of 75 ppm, it is likely that the blend
valve will need to be opened.
The desired reading of 75 ppm is at the high end of the solid
blue range. To be certain the blended water is at or near 75
ppm, use the following procedure:
1. CLOSE the mixing valve. Allow RO water to run for two (2)
minutes.
2. OPEN the mixing valve 1/4 turn, and run blended water
for two (2) minutes. Discard this water.
3. Run blended water into a glass and collect 1" to 2" of
water.
4. Test this water for a TDS level. Based on the result, the
mixing valve will be opened or closed.
• If the meter showed a solid blue light, then the mixing
valve will be OPENED more.
• If the meter showed any other indicator, then the
mixing valve will be CLOSED more.
5. Adjust the mixing valve if needed and run blended water
for two (2) minutes. Discard this water.
6. Repeat Steps 3, 4 & 5 until the light indicators change
between solid blue and flashing blue. The blended water
TDS should now be at 75 ppm.
TESTING YOUR REVERSE OSMOSIS SYSTEM
Total Dissolved Solids (TDS) Test
Under NSF/ANSI Standard 58, it is highly recommended that
the blended water be tested at least every six (6) months to
verify that the system is performing satisfactorily.
WHEN TO CHANGE THE CARTRIDGES
The life of the cartridges depend 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-S and 4CC Cartridges need to be changed when
the water pressure at the application equipment valve begins
to drop noticeably or if there are changes in the flow of the
blended water. All cartridges should be changed at the
same time.
NOTE: Only the replacement cartridges listed can be used
with this system. Failure to use the recommended
replacement cartridges will void your warranty.
1. Place a small pan or towel under the Everpure Conserv
75E System to catch any water that may drip. Turn OFF
incoming water.
2. OPEN the application equipment valve to drain the
storage tank and relieve pressure.
3. Remove the two (2) front 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. Replace the flow controller (Figure 10) in the red tubing
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.
6. Remove the old flow controller (Figure 10) with the tube
and discard.
7. Insert a new flow controller (Figure 10) with capillary
tube into the tubing. Replace the quick-connect elbow.
