Your ONE™cartridge tank filters are precision built, high quality products. These units will deliver filtered water
for many years to come, when installed and operated properly. Please study this manual carefully and understand
the cautions and notes before installing. This manual should be kept for future reference. If you have any questions
regarding your water filter, contact your local dealer, or the manufacturer at the following:

PREINSTALLATION INSTRUCTIONS:
3
The manufacturer has preassembled the cartridge filter tank. The actual cartridge filter is shipped
separately and will need to be installed into the tank to complete assembly.
The dealer should read this complete guide to familiarize the installer with assembly, installation and
operation of the cartridge filter system.
The site selection for the ONE™ Filtration System may vary depending on the purpose it will serve.
This versatile filter may be used as pre- or post-filtration in a water treatment system. Depending on the
application, this system can also be utilized as a single tank system.
Regardless of application, provisions should be made so that the system is located close to a drain.
An optional bottom drain is available for these cartridge filter systems to allow rinsing of the cartridge.
When replacing the cartridge, water may spill from the housing; therefore, precautions should be taken
to prevent any damage due to water while rinsing or replacing the cartridge.
For the owner, please read operating and cartridge replacement change out instructions.
The bypass valve is typically used to isolate the filter from the plumbing system’s water pressure in order
to perform repairs or maintenance. The 1" full flow bypass valve incorporates four positions, including a
diagnostic position that allows a service technician to have pressure to test a system while still providing
untreated water to the building. Be sure to install bypass valve onto the head assembly before beginning
plumbing. Or, make provisions in the plumbing system for a bypass. The bypass body and rotors are
glass-filled Noryl®and the nuts and caps are glass-filled polypropylene. All seals are self-lubricating EPDM
to help prevent valve seizing after long periods of non-use. Internal O-rings can easily
be replaced if service is required.
The bypass consists of two interchangeable plug valves that are operated independently by red arrow
shaped handles. The handles identify the direction of flow. The plug valves enable the bypass valve to
operate in four positions.
1. NORMAL OPERATION POSITION: The inlet and outlet handles point in the direction of flow,
indicated by the engraved arrows on the control valve (Fig. 1, page 4).
2. BYPASS POSITION: The inlet and outlet handles point to the center of the bypass. The system is
isolated from the water pressure in the plumbing system. Untreated water is supplied to the building
(Fig. 2, page 4).
3. DIAGNOSTIC POSITION: The inlet handle points toward the control valve and the outlet handle
points to the center of bypass valve. Untreated supply water is allowed to flow to the system and to
the building, while not allowing water to exit from the system to the building (Fig. 3, page 4).

4. SHUT OFF POSITION: The inlet handle points to the center of the bypass valve and the outlet
handle points away from the control valve. The water is shut off to the building. The water treatment
system will depressurize upon opening a tap in the building. If water is available on the outlet side of
the filter, it is an indication of water bypassing the system (Fig. 4) (i.e. a plumbing cross-connection
somewhere in the building).

Provisions should be made to install three bypass valves around the EF-835-2 cartridge filter tank. Because
of the pipe size, this will need to be created on the job site. Any piping materials may be used; however,
be sure to observe local plumbing codes. These bypass valves should allow for water to be turned off to the
filter tank for future cartridge replacement, and allow for system bypassing should other service be required.
BYPASS INSTALLATION FOR EF-835-2:
NOTE: Drain should be considered in plumbing of
system as per diagram. Opening drain valve will allow
for flushing of cartridge. Closing inlet and outlet valve
and opening drain will relieve pressure on filter tank for
cartridge replacement.

GENERAL INSTALLATION & SERVICE WARNINGS
The control valve, fittings and/or bypass are designed to accommodate minor plumbing misalignments.
There is a small amount of “give” to properly connect the piping, but the filter is not designed to support the
weight of the plumbing.
Do not use Vaseline, oils, other hydrocarbon lubricants or spray silicone anywhere. A silicone lubricant may
be used on black O-rings, but is not necessary. Avoid any type of lubricants, including silicone, on red or
clear lip seals.
Do not use pipe dope or other sealants on threads. Teflon®tape must be used on the threads of the 1"
NPT inlet and outlet, the brine line connection at the control valve, and on the threads for the drain line
connection. Teflon®tape is not used on the nut connections or caps because O-ring seals are used.
The nuts and caps are designed to be unscrewed or tightened by hand or with the special plastic Service
Wrench, #CV3193-02. If necessary, pliers can be used to unscrew the nut or cap. Do not use a pipe
wrench to tighten nuts or caps. Do not place screwdriver in slots on caps and/or tap with a hammer.
SITE REQUIREMENTS
• water pressure – 25-100 psi
• water temperature – 33-100°F (0.5-37.7°C)
• the tank should be on a firm level surface
1. This unit is equipped with a 1.25" CPVC connection at the bottom of the tank. This connection is for an
optional drain. It may be desirable to rinse the cartridge filter periodically. If this is installed, location of the
tank to the actual drain should be as close as possible.
2. Do not install any water filter with less than 10 feet of piping between its outlet and the inlet
of a water heater.
3. Do not locate unit where it or its connections (including the drain) will ever be subjected to room
temperatures under 33°F.
4. Do not subject the tank to any vacuum, as this may cause an “implosion” and could result in leaking. If
there is a possibility a vacuum could occur, please make provision for a vacuum breaker in the installation.

5. INLET/OUTLET PLUMBING: Be sure to install bypass valve onto main control valve before
beginning plumbing. Make provisions to bypass any outside hydrant at this time. Install an inlet
shutoff valve and plumb to the unit’s bypass valve inlet located at the right rear as you face the
unit. There are a variety of installation fittings available. They are listed under Installation Fitting
Assemblies, pages 13-14. When assembling the installation fitting package (inlet and outlet), connect
the fitting to the plumbing system first and then attach the nut, split ring and O-ring. Heat from
soldering or solvent cements may damage the nut, split ring or O-ring. Solder joints should be cool
and solvent cements should be set before installing the nut, split ring and O-ring. Avoid getting solder
flux, primer, and solvent cement on any part of the O-ring, split rings, bypass valve or control valve. If
the building’s electrical system is grounded to the plumbing, install a copper grounding strap from the
inlet to the outlet pipe. Plumbing must be done in accordance with all applicable local codes.
6. INSTALLING GROUND: To maintain an electrical ground
in metal plumbing of a home’s cold water piping (such as
a copper plumbing system), install a ground clamp or
jumper wiring.
NOTE: If replacing an existing filter, also replace the ground
clamps/wire.
7. DRAIN LINE: First, be sure that the drain can handle the rinse
rate of the system. At the bottom of the tank is a 1.25" CPVC
socket to accommodate a drain. The manufacturer does not
provide the fittings for this. The purpose of the drain
is to manually (or automatically, if desired) rinse the filter
tank and cartridge of any debris. This can prolong the life
of the cartridge.
CAUTION: If a drain is not used or
the installation makes this
unavailable, the 1.25" hole must
be plugged or water will flow
from this outlet.
For installation of the EF-835-2, please plumb according to the diagram on the following page.
If the cartridge tank is rinsed periodically (see bypass instructions on page 5), it is important
to locate the cartridge tank as close to the drain as possible. This rinsing can prolong the life of the
cartridge. The drain port can also be used to relieve pressure and drain water from the tank during
cartridge filter replacement.
Be sure to observe local and applicable plumbing codes.

1. Turn off water supply to vessel using bypass inlet and outlet lines. See page 4 for bypass diagrams.
2. Release pressure on system by opening bottom drain for a moment, then close. If bottom drain is not
installed, turn off water to inlet side of filter and open an outlet line to the filter.
3. Disconnect bypass from valve assembly using the nuts at the inlet and outlet head assembly. Be careful
not to disconnect the nuts at the plumbing lines as these are under pressure.
NOTE: This unit is equipped with an adapter, attached to the underside of the head assembly,
which accepts the O-rings of the cartridge. If the adapter is not in place, check in bottom of filter tank
assembly as shipping may have dislodged this. Reattach to underside of valve housing, if necessary.
This should only be required upon initial install.
4. Remove retaining ring which holds top cap in place (see photo to right).
Push down on top cap equally to unseat the ring. To remove, pull on retaining
ring handle by pulling inward and then upward. This will release ring from
grooved seal.

Locate product description tag and keep for future use.
8. Lubricate O-ring on adaptor to ensure proper sealing. Do not use pipe dope, Vaseline, oils
or other unacceptable lubricants on O-rings. Food grade silicone lubricant is recommended.
9. Place cartridge into filter housing with adaptor “stub” at the top of the tank.
10. Place top adaptor piece onto cartridge “stub”
(see photo to right). Carefully replace top cap
assembly making sure that the adaptor slips into the
top cap assembly. Push down on cap assembly. This
will make room for replacement of ring assembly
(see photo to right).
11. Attach product description tag to retaining ring for future reference (see
photo to right). Insert retaining ring into ring groove, starting at the end
opposite of the handle. Gently push retaining ring into groove until the entire
ring is in place and both ends meet in the groove section. To ensure proper
engagement, hold retaining ring by handle and slightly rotate around the
inner diameter of the cartridge tank.
12. Reconnect cartridge tank to bypass valve by securing nuts.
13. Open a treated water line and turn bypass valve to the service position (Fig. 1, page 4) and allow
water to fill tank slowly. Once water is flowing to treated water faucet, observe tank for any leaks.
