MRS-600HE-II High Efficiency Reverse Osmosis System
Mineral Reduction System For Foodservice Applications
Introduction
The Everpure MRS-600HE-II Mineral Reduction System is a preengineered, pre-assembled Reverse Osmosis (RO) system designed
to provide high purity water for multiple applications, such as
premium espresso, coffee, blended beverages and steam, to name a
few. It combines a number of water treatment technologies into one
easy to install package. The system provides superior protection
against taste and odor causing contaminants † while removing dirt †,
particulates † and dissolved solids that can foul or scale equipment.
Initial System Production
Water production depends on supply water pressure and temperature.
See PERFORMANCE section (page 9) for normalized production.
Influent Water Characteristics
The following table lists the allowable operating range of various
water properties within which the MRS-600HE-II will function
properly.

7FS-BW Water Filtration Cartridges
Inlet Booster Pump
MR-600 Reverse Osmosis (RO) Membrane Cartridge.
Permeate Pump
MC 2 or 7F Water Filtration Cartridges
Control System with Power Supply
The 7FS-BW water filtration cartridges contains multiple medias.
These medias filter out dirt and particles, reduce chlorine and
provides scale control, which extends RO membrane life.†
The inlet booster pump increases the inlet pressure to maintain
consistent permeate production.
The MR-600 RO membrane cartridge contains a semi-permeable
reverse osmosis membrane. Here, most 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, RO water, or
product water.
The permeate pump minimizes backpressure on the permeate
produced by the MR-600 cartridge. This virtual elimination of backpressure provides consistent permeate production and maximizes
system efficiency.
See MRS-600HE-II Installation Addendum - Excerpt 1.
The MC 2 or 7F cartridges act as post-filters, filtering the RO water,
and any tap water added via the blending system.*

3. Refer to Figure 1 for mounting bracket details. Position the top
row of holes 19⁄16 “ (39.7 mm) above the top of the processor when
installed. Install the wall mount bracket to a suitable vertical
surface. Use no less than 4 - #12 (5.5 mm) fasteners to secure the
bracket to the surface.
4. Prepare to attach the processor to the wall mount bracket. Lift the
processor and “hook” the metal lip of the processor backplate
over the lower lip of channel on the wall mount bracket. Go to step
6.
5. Measure and install 2 - #12 (5.5 mm) minimum fasteners on 16”
(406.4 mm) centers to engage the top edge of the processor
backplate, leaving a 1/4” (6.4 mm) gap. Lift the processor and
“hook” the key-hole slots on the processor backplate. Tighten
the 2 fasteners.
6. Install 2 - #12 (5.5 mm) minimum fasteners in the 2” (50.8 mm)
wide slots along the bottom edge of the processor backplate.
Piping/Tubing Connections
1. Refer to Figure 2 and 10 for general arrangement views of the
piping, with a description of major components and connection
points. These major components and connections will be
referred to in the following steps.
2. A parts kit has been provided, which includes valves and tees to
configure a system by-pass.
• If both hard water and soft water are available, assemble the
parts to the system using the example shown in Figure 2.
• If only hard water is available, assemble the parts to the
system using the example shown in Figure 3.
3. Prepare the plumbing to accept the RO system.
Note: T he product water tubing/piping and associated fittings
connecting the RO product 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). The product 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 choices for RO water
distribution materials. The size of the product water tubing/
piping should be 3/8” (9.5 mm) ID minimum. Distances of 25
feet (7.6 m) or greater from the RO to the equipment being
serviced should be 1/2” (12.7 mm) ID minimum.
4. 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 INLET - Hard
Water fitting. See Figure 2 or 3.
5. If soft water is available, complete step 6. If not, go to step 7.
6. 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 INLET - Soft Water
fitting. See Figure 2.
7. Connect the appropriate size and type of tubing/piping and
associated fittings to the MRS-600HE-II outlet connection. Route
the line(s) to the equipment being serviced (i.e.; steam, espresso,
coffee, etc.). Close the hard and soft inlet, outlet and by-pass
valves on the RO system. Re-apply pressure to the hard water
and soft water distribution plumbing by slowly opening the shutoff valves that were closed in the previous steps.
8. See MRS-600HE-II Installation Addendum - Excerpt 3.
9. Connect a 3/8” (9.5 mm) OD tube to the reject Y-connector
(labeled WASTE) located in the lower right corner of the
processor. 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 Figures 2, 4 and 10.
WARNING Refer to “Reject to Drain, Maximum” under RO Production in the Performance Table (page 9) to determine the
maximum reject (waste) flow rate. Verify the drain has ample
capacity for this waste flow, plus all other sources of waste flow
sharing this drain.
Control system operation
The MRS-600HE-II system includes a micro-processor based control
system that monitors system conditions and controls the system
operation. A digital display panel provides operational information
and 3 buttons provide operator access. To follow is a list of modes
and a description of each function. Use this as a guide during
startup, normal operation and when service is required.

Recovery adjustment/calibration
1. Carefully remove and RETAIN the factory installed capillary
tubes (restrictors) from the end of the two 1/4“ (6.4 mm) OD
tubes connected to the upper Y-connector on the reject line,
then re-connect the lines. Store these restrictors with the other
restrictors in the parts kit for possible re-use in the following
steps. See Figures 5 and 6.
2. Locate the needle valve from the parts kit. Attach a section of
3/8” (9.5 mm) OD tubing to this valve. Open valve partially.
NOTE: T he needle valve will be used to adjust/calibrate the system
recovery. Once calibration is complete, it is removed.
3. Remove the 3/8” (9.5 mm) OD tube from the reject Y-connector
and install the needle valve assembly. Connect a section of
BLACK 3/8” (9.5 mm) OD tubing to the outlet of this valve. See
Figure 5 for details on the calibration set-up.
4. Measure the raw water hardness and TDS. Refer to Table 1 on

in the second container. Compare the
ratio of volume collected to the data shown in Table 1. Adjust
the reject needle valve as needed to match the ratio specified.
Empty the containers and collect additional samples after each
adjustment of the reject needle valve.
6. Once the ratio of Permeate-to-Reject closely matches the data
in Table 1, the Reject ONLY volume requires measurement. Using
only 1 graduated cylinder, collect the Reject ONLY (black line)
flow for 1 minute and record this volume.
NOTE: Reject volume in 1 minute may exceed 32 oz./1,000 ml. If
so, use a larger container, or collect samples in multiple
containers and add all of the collected volumes together.
7. Unplug power cord. Close drain/sample valve.
8. Return to page 7, Table 2. Find the volume range in the column
labeled “Reject Volume per Minute” that corresponds to the
volume collected in Step 6. Read across that same row to
identify the correct capillary tube combination, located under the
columns labeled “Capillary Tube #1 & #2”.
9. Locate the correct capillary tubes (restrictors) from the parts
kit. Remove the two 1/4“ (6.4 mm) OD tubes from the upper
Y-connector. Insert the capillary tubes into each line and reassemble to the Y-connector. See Figures 5 and 6.
NOTE: In some cases, the capillary tube requires trimming. Use a
SHARP utility knife to cut the tube cleanly without tearing or
crushing the tube.
10. Remove the reject needle valve assembly and reconnect the 3/8”
(9.5 mm) tube that is routed to drain.
11. Refer to Table 2 again and locate the column labeled “Flush Time
in Seconds”. The correct value for this setting can be found in the
same row of data used to determine the capillary combination
in the previous steps. Enter this value in the controller under
“FLUSH TIME XXX”.
12. Adjust “FLUSH INT X.X H” to 1.5 H.

Disinfection
Figure 7. RO Blend* Valve Locations
After completing the activation of the 7FS-BW cartridges and MR600 cartridge and adjusting the recovery, the system and associated
piping must be disinfected, then completely flushed. The steps
for this are outlined in the MRS-600HE-II Installation Addendum
- Excerpt 5.
Placing THE MRS-600HE-II Into Service
Once the cartridges have been activated, the system and distribution
piping sanitized, the MRS-600HE-II can be placed into service.
During normal operation, the valves on the MRS-600HE-II should be
in the following positions:
A. System inlet and outlet valves – open.
B. System by-pass valves – closed.
Once the system been started-up initially, it is a good idea to
measure the outlet water flow rate and quality to verify the system’s
performance. The initial values should be recorded for future
comparison to detect any changes in performance. A Performance
Log has been provided on Page 10 to record this information.
Operation
1. During normal operation, a continuous supply of water must be
available to the system.
2. The system inlet and outlet valves must be open, the sample
outlet and flushing valves must be closed and the drain line must
be unrestricted.
Tap Water Blend*
Valve (TWBV)
Dilution Water Blend*
Valve (DWBV)
BLEND ADJUSTMENT*
The MRS-600HE-II system includes a blend system that can produce
a wide range of water qualities. It combines or “blends” two sources
of water; 1) directly from the RO Membrane and, 2) water containing
the same level on mineral content as the raw (tap) hard water. The
following text describes the adjustment of this feature.
1. Open the tap water blend valve (TWBV) and dilution water
blend valve (DWBV) fully. See Figure 7 for location of these
valves.
2. Demand flow on the “OUTLET - RO Water” line. The flow
rate should equal the maximum expected demand of all
connected equipment.
3. Access the “COFFEE TDS: XXX” view screen on the
controller to observe a real-time reading of the TDS quantity
in the water flowing to the “COFFEE” line.
4. Compare TDS value on controller to application
requirement. If controller reading is higher than
requirement, slowly close TWBV until TDS value is met. If
controller reading is lower than requirement, slowly close
DWBV until TDS value is met.
* Blend system not performance tested or certified by NSF.

Maintenance
The MRS-600HE-II requires very little maintenance. Regular
cartridge replacement, system recovery verification, See
MRS‑600HE-II Installation Addendum - Excerpt 8,and sanitization
are the only normal requirements. In typical service, the schedules
are as listed below.
Every 6 months
– Replace the MC 2 cartridges:
• Open both by-pass valves.
• Remove power from system by unplugging power cord.
• Close HARD water inlet valve, SOFT water inlet valve, RO water
outlet valve and See MRS-600HE-II Installation Addendum Excerpt 9.
• Route a temporary line from open port of post-filter flush valve to
a bucket or drain. Open post-filter flush valve. See Figure 2.
• Place a bucket under exhausted MC 2 cartridge to catch any
excess water that may spill from head. Remove exhausted
cartridge by turning cartridge to the left until it stops and pulling
downward until it is free from head. Remove second cartridge in
the same manner.
• Remove outer shrink-wrap and protective cap from the new
MC 2 cartridges.
• Align lugs on new cartridge with slots in head.
• Holding head and cartridge firmly, press cartridge upward into
head fully, then turn the cartridge to right until it stops. Install
second cartridge in the same manner.
• Open HARD water inlet valve and flush for 5 minutes or until

• Route a temporary line from drain/sample valve to a bucket or
drain. Open drain/sample valve and allow to remain open until
system starts processing water. Close drain/sample valve and
remove temporary line.
• Using only 1 graduated cylinder, collect the Reject ONLY flow for
1 minute and record this volume.
• Compare this volume to the volume of reject flow recorded
previously. If the volume varies more than +/- 5% from the
previous recorded volume, see troubleshooting section for
possible cause and remedy. If the correct flow cannot be
attained , see “RECOVERY ADJUSTMENT/CALIBRATION”
