EVERPURE® CONSERV® HE-3 RO SYSTEM INSTALLATION AND OPERATION GUIDE

The system consists of seven (7) major components:

• Everpure® SEN+ Fine Filter Cartridges*

• Inlet Booster Pump

• Everpure MR-600F Reverse Osmosis (RO) Membrane
Cartridge

• Permeate Pump

• Everpure SEN Fine Filter Cartridge*

• Control System with Power Supply

• 15 Gallon Storage Tank

The SEN+ Fine Filter Cartridges contain multiple medias.
These medias filter out dirt and particles, reduce chlorine
and provide scale control, to extend RO membrane life.*

The Inlet Booster Pump increases the inlet pressure to
maintain consistent permeate production.

The MR-600F RO Membrane Cartridge contains a semi­permeable reverse osmosis membrane. It’s here that most
of the dissolved impurities are separated from the water
and flushed down the drain. The water that is able to pass
through the membrane, which is very low in dissolved
impurities, is referred to as permeate or RO water.

The Storage Tank minimizes back pressure on the permeate
produced by the MR-600F RO Membrane Cartridge. This
reduction of back pressure provides consistent permeate
production and maximizes system efficiency for peak demand.

The SEN Fine Filter Cartridge acts as a postfilter, filtering the
RO water and any tap water added via the blending system.*

SELECTING A MOUNTING LOCATION

Locate the system in an area that is convenient to the inlet
water supply and drain facilities, with access for routing
the blended water tubing/piping to the equipment. Install
in a dry location, away from all forms of corrosive and/or
flammable materials. Consider ease of access for servicing
when selecting a location. If the Conserv HE-3 RO System
is replacing an existing Everpure® MRS-600HE-II High
Efficiency RO System the mounting system may be reused.
The Conserv HE-3 is designed to mount using the MRS-600
HE-II wall mount brackets. The Conserv HE-3 may also be
mounted using a new design wall mount hinge system (sold
separately).

If the Conserv HE-3 RO System is wall mounted on hinges be
certain the unit has clearance to swing out for maintenance.
Evaluate the mounting surface for its ability to properly
support the weight of the processor when in operation
[approximately 90 lbs (40.8 kgs)].

SYSTEM ASSEMBLY

WARNING: Mounting surface may require reinforcement to

support the Processor Assembly safely. Hollow
walls, drywall and other non-structural surfaces
are not suitable for mounting unless reinforced.

WARNING: Do not use screws smaller than #12 (5.5 mm) for

mounting the Processor Assembly.

The Everpure® Conserv® HE-3 Processor Cabinet is designed
to wall mount using either of two (2) methods.

1. If an Everpure® MRS-600HE-II System is being replaced,
the mounting brackets can be reused. The new Conserv
HE-3 will not swing open when using these brackets.

2. A mounting kit may be purchased that includes two (2)
hinges and a template with instructions. This mounting
kit allows the Conserv HE-3 to swing open for access to
the back of the cabinet.

1

Wall Mounting Using the Hinged Mounting Kit

The Everpure® Conserv® HE-3 Processor Cabinet can have
two (2) mounting hinges attached to one side of the cabinet.
The second half of the hinge is separate and will be mounted
to the wall. See Figure 5 for Dimensions. When this half of the
hinge is correctly mounted to the wall, it allows the cabinet to
be lifted and the hinge pieces to connect to each other.

NOTE: When the processor cabinet is hinge-mounted, it

can swing away from the wall to allow servicing.
Determine that the application site will allow the
cabinet to swing in the desired direction.

CAUTION: Be certain that the holes are vertically level.

Any deviation will cause the Conserv HE-3 RO
System Cabinet to swing during servicing.

1. Place the two (2) hinges in position over the mounting
holes with the pegs pointing up.

2. Secure the hinges with appropriate hardware.

Tubing Locations

1. Refer to Figure 6 Conserv HE-3 RO System Assembly
for a description of major components and connection
points. These major components and connections will be
referred to in the following steps.

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 100 psi (6.9 bar,

0.69 MPa). The blended water may react with metal
piping, creating a corrosive condition in addition
to imparting an objectionable taste. 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 1/2-inch (12.7 mm) O.D. minimum. Distances of
25 feet (7.6 m) or greater from the RO system to the
equipment being serviced should be 1/2-inch (12.7
mm) O.D. 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 system. CLOSE the nearest shut-off valve
that is upstream from the tie-in point and relieve the
pressure in the line. Tie in the new tubing/piping section
and connect it to the Hard Water Inlet fitting. See Figure
6 Conserv HE-3 RO System Assembly.

®

CONSERV® HE-3 RO SYSTEM INSTALLATION AND OPERATION GUIDE

11 EVERPURE

4. Locate an appropriate point in the soft water plumbing
to tie in a new section of tubing/piping that can be routed
to the RO system. CLOSE the nearest shut-off valve
that is upstream from the tie-in point and relieve the
pressure in the line. Tie in the new tubing/piping section
and connect it to the Soft Water Inlet fitting. See Figure 6
Conserv HE-3 RO System Assembly.

5. Connect the appropriate size and type of tubing/piping
and associated fittings to the Everpure® Conserv® HE-3
RO System. Route the line(s) to the equipment being
serviced (i.e., steam, espresso, coffee, etc.). CLOSE the
Hard and Soft Water Inlet Valves, and the Blended Water
Outlet Valve on the RO system. Reapply pressure to
the hard water and soft water distribution plumbing by
slowly OPENING the shut-off valves that were closed in
the previous steps.

6. Connect a 1/4-inch (6.3 mm) O.D. tube to the port located
at the bottom of the processor labeled WASTE. Route
the other end of the tubing to a drain nearby, securing
it properly. Allow an air gap at the drain, following
any applicable local and national codes. See Figure 6
Conserv HE-3 RO System Assembly.

ELECTRICAL AND CONNECTIVITY CONNECTIONS

The Everpure® Conserv® HE-3 RO System is pre-wired at the
factory. Verify that the supply voltage matches the RO system
operating voltage. Also verify that the supply is a GFI, RCD, or
equivalent protected circuit rated at 15 amps minimum. Verify
that the pump motor switch (Figure 8) is in the off position.
Plug in the power cord.

The bottom of the Everpure Conserv HE-3 RO System has two
electrical connections. The permeate Storage Tank sensor
will plug into the white connector. The Storage Tank pump
power cord will plug into the remaining female connection.

WARNING: For proper operation, do not plug Storage Tank

pump into a wall receptacle.

IMPORTANT: Electrical brown-outs below 100 volts will

require the Everpure Conserve HE-3 RO
System must be turned OFF and back ON
(power cycled).

To monitor the Everpure Conserv HE-3 RO System remotely,
an Ethernet cable (type CAT5, not provided with the system)
must be connected between the RO system and the Internet
router.

To have connectivity between the Everpure Conserv HE-3
RO System and the CES-9100TS E-30C Softener, a phone
cord (type 4 pin RJ11, not provided with the system) must be
connected between the RO system and the softener.

Sanitize Storage Tank

1. Attach a length of 3/8-inch O.D. tubing to the Storage
Tank Inlet Tee fitting. The tubing should be long enough
to reach the Prefilter Flush Port.

2. Use an air gauge to check the tank's precharge. It should
be 40 psi (2.75 bar, 0.275 MPa).

3. Use an eye dropper or funnel to place 8 oz. (237 mL) of

5.25% bleach (200 ppm) into the tubing.

4. Connect the tubing to the Prefilter Flush Port
(Figure 11). Use the 3/8" to 1/2" adapter and a short
piece of 1/2" O.D. tubing.

SYSTEM RECOVERY RATE

The amount of incoming water that becomes RO water
should be 80%. This recovery percentage may be changed
by replacing the flow restrictor in the black waste tubes
located in the RO waste tubing connectors. There is one Flow
Restrictor for each RO head. They are accessed from the top
of the manifold tray.

CAUTION: The system should be run on 80% recovery when

tempered, softened, and under 1,000 ppm TDS
water is available. Any deviation from an 80%
recovery rate will affect the system's production
rate and/or life of the RO membrane. Please

Check electrical connector engagement with pressure transducer.

RO permeate pressure exceeds 114 psi (0.79 MPa). Check for restriction/blockage in permeate line causing abnormally high pressure. Relieve

pressure in permeate line and correct restriction/blockage condition.

RO cartridge bypassing. Measure RO permeate flow and TDS, then compare to previously recorded values or system

specifications. High permeate flow and/or poor TDS reduction indicates excessive passage of
water around or within the RO cartridge. Remove the RO cartridge and check the integrity of all

MAINTENANCE

The Everpure® Conserv® HE-III System requires very little
maintenance. Regular cartridge replacement, system
recovery verification, and sanitization are the only normal
maintenance requirements. Typical service schedules are as
listed below.

Every 12 Months (Recommended)

Replace all of the cartridges and sanitize the permeate
storage tank.

Switch and valve starting positions:

• Power - OFF

• Soft Water Inlet Valve - CLOSED

• Hard Water Inlet Valve - CLOSED

• Blended Water Outlet Valve - CLOSED

1. Remove the cover on the Conserv HE-3 RO System.

NOTE: When the cartridges are removed, water will leak

from the heads. Be prepared to catch or clean up any
spills.

2. OPEN the outlet valve. Use the application equipment to
release water pressure. CLOSE the outlet valve.

3. Have the new replacement cartridges ready to install.
Remove all the old cartridges by grasping the outside of
the cartridge. Push up and turn it to the left until it stops.
The cartridge will then pull straight down and out.

4. Refer to "Prefilter and RO Cartridge Installation and
System Start-up" on page 12. Perform Steps 1
through 14.

5. Refer to the section "7 Prepare Storage Tank" on
page 14. Perform Steps 2 through 17.

6. Refer to the section "10 Flush Everpure Postfilter
Cartridge" on page 16, Perform Steps 1 through 10.

The system is ready to run. Use application blended water
for five (5) minutes and test the TDS. If the measured
TDS reading is not within the required specification of the
application, then the blend should be adjusted.

7. To adjust the TDS of the blended application water, refer
to the "

Adjust The Blending Valves" on page 16.

COMPLIANCE STATEMENTS

Check for compliance with state and local laws and regulations.

Do not use with water that is microbiologically unsafe, or of
unknown quality without adequate disinfection before or after
the system.

Substances reduced are not necessarily in your water. System
must be maintained according to manufacturer’s instruction,
including replacement of filter cartridges.

This system contains a replaceable mineral reduction (RO)
module critical for the effective reduction of total
dissolved solids.

Blended water should be tested periodically to verify that the
system is working properly.

This reverse osmosis system contains a replaceable
component critical to the efficiency of the system.
Replacement of the reverse osmosis component should
be with one of identical specifications, as defined by the
manufacturer, to assure the same efficiency and containment
reduction performance.

Recovery rating refers to the percentage of the influent water to
the membrane portion of the system that is available to the user
as reverse osmosis treated water when the system is operated
without a storage tank or when the storage tank is bypassed.

Efficiency rating means the percentage of the influent water
to the system that is available to the user as reverse osmosis
treated water under operating conditions that approximate
typical daily usage.
