Connect Tubing for Cartridge Flushing:
1. Refer to Figure 3 for a general description of connection
points.
2. Prepare the plumbing to accept the RO system.
NOTE: The blended water tubing/piping and associated
fittings connecting the RO blended water outlet to
the equipment being serviced should be food-grade
material that meets NSF
®
Standard 51, 61, or similar,
with a minimum pressure rating of 125 psi (8.6 bar,
0.86 MPa). The blended water may react with metal
piping, creating a corrosive condition. Plastic pipe or
reinforced beverage tubing are generally very good
material choices for RO water distribution piping.
The size of the blended water tubing/piping should
be 3/8" (9.5 mm) ID minimum. Distances of 25 feet
(7.6 m) or greater from the RO processor to the
equipment being serviced should be 1/2" (12.7 mm)
ID minimum.
3. Locate an appropriate point in the hard water plumbing
to tie in a new section of tubing/piping that can be routed
to the RO processor. CLOSE the nearest shut-off valve
that is upstream from the tie-in point and relieve the
pressure in the line. Install a 3/8" (9.5 mm) tubing/piping
section and connect it to the INLET - Supply Water fitting.
See Figure 3.
4. Connect a length of 3/8" O.D. tubing to the connection
for the Storage Tank. Route the other end to the Storage
Tank and insert it into the ball valve. The ball valve
should be closed.
5. Connect a length of 3/8" O.D. tubing to the Everpure
Conserv LT-S Processor outlet connection. Secure an
open ball valve to the other end and position it over a
drain.

Prepare to Flush the Everpure 4FC5 Cartridge:
The Everpure 4FC5 Filter Cartridge is installed and flushed
before the Pentair GRO-75EN RO and the Everpure 4CC
Cartridges are installed.
1. Install the bypass plug into the filter head for the
Everpure 4CC Cartridge. This head is centered and
toward the front of the unit.
2. Connect the electrical cord to the socket located on the
power supply.
3. The inlet water should be connected and turned off.

Install and Flush the Everpure 4FC5 Filter Cartridge:
Locate the 4FC5 Filter Cartridge and inspect the o-rings.
They should be clean and lightly lubricated with silicone
grease.
1. Line up the tabs with the slots in the opening on the left
side of the head assembly. See Figure 5 and Figure 6.
2. Insert the cartridge to full depth.
3. Rotate the cartridge 90

to the right (clockwise) to lock it
in place.
