S HIGH EFFICIENCY RO SYSTEM INSTALLATION AND OPERATION GUIDE
HOW REVERSE OSMOSIS (RO) WORKS
The Everpure Conserv LT-S Processor uses a semi-
permeable membrane to reduce scale and corrosion. The RO
membrane cartridge contains multiple layers of micron-thin
film wound around a hollow center core. Water molecules can
pass through the cartridge, while dissolved salts are rejected.
Your water supply is prefiltered to reduce dirt and chlorine
that may foul the membrane. The RO membrane cartridge
separates this prefiltered water into RO WATER and REJECT
WATER. Water pressure forces water through the membrane
within the RO membrane cartridge then into the storage tank.
This is the RO water. Dissolved salts cannot pass through the
membrane and are sent to the drain as reject water.
The Conserv LT-S Processor features a blend-in-tank process
which uses the RO water described above, with calcium
carbonate, and adds filtered water from carbon filtration to
create a consistent product water. When you use water from
the storage tank, the pressure inside the tank drops and the
pressure switch closes. The system then begins to operate,
replenishing the water you took from the storage tank. The
storage tank can hold up to 3 gals (11.3 L) of water at one
time.
NOTE: When used under operating conditions specified
in this manual, the RO membrane cartridge of the
Conserv LT-S Processor should last 12 to 24 months.
The precise life span of the Pentair
®
GRO-75EN RO
Membrane Cartridge will depend on the quality of
the water entering the system and the frequency
with which you use it. Frequent use prevents the
dissolved salts from building up on the membrane
as scale. The more water the system is required to
produce, the longer the membrane will last.
INSTALLATION
NOTE: Please read all instructions, specifications, and
precautions before installing and using your
Conserv LT-S Processor.
NOTE: The Conserv LT-S Processor may be installed
hanging on a wall or set under a sink.
NOTE: The Conserv LT-S Processor must be installed
vertically.
WARNING: Improper connection of the appliance-
grounding conductor can result in a risk
of electric shock. Check with a qualified
electrician or service representative if
you are in doubt as to whether or not
the appliance is properly grounded. Do
not modify the plug provided with the
appliance; if it will not fit in the outlet,
have a proper outlet installed by a
qualified technician.

Secure Manifold Wall Mount:
The Conserv LT-S Processor weighs approx. 25 lbs (11.3 kgs).
CAUTION: The Conserv LT-S Processor should be mounted
on a stud or firm surface. The mounting bracket
will support the weight of the system and help
prevent strain on the water lines.
1. Remove the Pentair GRO-75EN Membrane from the clip
on the wall unit.
2. When mounting the Conserv LT-S Processor on a wall,
four (4) screws are required to mount the unit. The
two (2) top screws will be 10.5" (26.7 cm) apart and
level. Screw the two (2) screws into the wall. Leave a
gap between the screw head and the wall of 1/8". The
backside of the unit has two (2) slots that will fit over the
screw heads and slide down to lock (Figure 2).
3. Tighten both screws from the front.
4. Insert screws into the two (2) remaining mounting holes.
Screw them in and tighten.

Assemble Storage Tank:
1. Locate the right angle ball valve. Screw the valve onto the
top fitting of the Storage Tank until tight.
2. CLOSE the ball valve.
3. Apply precharge of 5-7 psi (0.34 bar, 0.034 MPa)
4. Position the Storage Tank near the Conserv LT-S
Processor.
