MRS600HE HIGH EFFICIENCY

REVERSE OSMOSIS (RO) SYSTEM

MINERAL REDUCTION SYSTEM FOR FOODSERVICE APPLICATIONS

INTRODUCTION

The Everpure MRS-600HE High Efficiency RO System is
a pre-engineered, preassembled Reverse Osmosis (RO)
solution designed to provide high purity water for multiple
applications such as premium espresso, coffee, blended
beverages and steam. It combines a number of water
treatment technologies into one easy-to-install package,
providing superior reduction in total dissolved solids (TDS)
which can foul or scale water
using equipment.

Initial System Production

Water production depends on supply water pressure and
temperature. See Performance section (page 13) for
normalized production.

Influent Water Characteristics

Allowable operating range of various water properties within which the MRS-600HE System will function properly.

MRS-600HE EV9970-85 (Special Applications - US Market)

NOTE: The MRS-600HE System does NOT include on-board particulate or organic reduction filtration. Incoming water supplies that do not meet the influent water characteristics
requirements will require the addition of pretreatment equipment prior to the MRS-600HE System. Do not connect the MRS-600HE System after any other water filtration system, unless
specifically provided or specified. System performance may be affected if requirements are not met, including system output and cartridge changeout frequency.

The system consists of five major components:

1. Everpure 2SR-BW Water Conditioning Cartridge*

2. Dual-head booster pump

3. Everpure MR-600, MR-600-1 or MR-600F Reverse
Osmosis (RO) Membrane Cartridge

The Everpure 2SR-BW Water Conditioning Cartridge contains media that reduces the scaling tendency of hard water minerals
found in many water supplies, extending RO membrane life.*

The dual-head booster pump increases the inlet pressure to maintain consistent permeate production, plus eliminates
back-pressure on the permeate output. This innovative approach to both boosting and eliminating back-pressure maximizes
system efficiency.

The Everpure MR-600, MR-600-1 or MR-600F RO Membrane Cartridge contains a semi-permeable 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, RO water, or
product water.

Once the RO water is produced, it is stored in the 6-gallon (22.7 l) RO water storage tank. This tank serves two (2) key functions;

1) it acts as a buffer between the system and the connected equipment, providing ample volumes of water instantaneously,

2) it reduces the on-off cycling of the RO system which produces better quality water and prolongs the system’s life.

SYSTEM ASSEMBLY

Do not use screws smaller than #12 (5.5 mm) for mounting the processor.

Mounting surface may require reinforcement to support processor safely. Hollow

walls, drywall and other non-structural surfaces are not suitable unless reinforced.

Processor Assembly Mounting

1. The MRS-600HE System has been provided with a wall mount bracket to allow greater installation flexibility and ease of
processor placement. If the wall mount bracket is not suitable for this specific application, the processor backplate has
four (4) mounting holes [two (2) keyhole slots, two (2) standard] on 16" (406.4 mm) centers for securing it directly to a
vertical surface.

2. Refer to Figure 9 (page 18) for dimensional information. Use this as your guide to determine the wall mount bracket
and / or processor location. If NOT installing the wall mount bracket, go to step 5.

3. Refer to Figure 1 (next page) 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 four (4)- #12
(5.5 mm) fasteners to secure the bracket to the surface.

3. Prepare the plumbing to accept the RO system.

Note: The 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, 0.69 MPa). 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 material choices
for RO water distribution piping. 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 system to the equipment being serviced should be 1/2" (12.7 mm) ID
minimum.

4. Shut off the supply of water to the new or existing filtration system and relieve pressure. Connect a line from the treated
water outlet of the filtration system to the inlet of the MRS-600HE System.

5. Connect the appropriate size and type of tubing / piping and associated fittings to the corresponding MRS-600HE System
outlet connection. Route the line(s) to the equipment being serviced (i.e.; steam, espresso, coffee, etc.). Close the inlet,
outlet and bypass valves. Apply pressure to the existing filtration system and place it back into service.

6. For safety in transit, the storage tank is shipped without a precharge. Locate the Schrader® valve on the storage tank and
precharge to 48 – 50 psi (3.3 - 3.4 bar, 0.33 - 0.34 MPa) with a source of clean, dry air. See Figure 3 (below).

7. 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 (page 4) and 4 (below).

Refer to “Reject to Drain, Maximum” under "RO Production in the Performance
Table" (page 10) 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 System includes a microprocessor based
control system that monitors system conditions and controls
the system operation. A digital display panel provides
operational information and three (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.

Operational Mode

• INITIAL POWER-UP: When power is first applied to the

system, the panel will display the system identification
with software version. After several seconds, it will
automatically transition to the MAIN SCREEN VIEW.

FIRMWARE 4.08

If the RO water pressure drops below the minimum
allowable pressure setting during DEEP FLUSHING, the
control will terminate the DEEP FLUSHING process and
remain idle until water is drawn. Once water is drawn,
the system returns to normal operation as described in
“PRESSURIZE” mode above.

RE-PRESSURIZE...
XXX PSI (BAR)

• PRESSURE LIMIT WARNING: This message indicates a

fault with the pressure sensing circuit or the detection
of pressure exceeding 114 psi (7.9 bar, 0.79 MPa). See
Troubleshooting Guide on page 15 for guidance on how to
correct this condition.

• MAIN SCREEN VIEW: When the system is in normal

operation and not operating in any of the following
operational modes, the panel will display the storage
tank water pressure.

PRESSURE XXX PSI (BAR)

• PRESSURIZE: When pressure in the storage tank drops

below the pressure “on” setting, the system will start
processing water and refill the storage tank. Once the
pressure in the storage tank rises above the pressure
“off” setting, the system will stop. Storage tank water
pressure will be displayed.

PRESSURIZE...
XXX PSI (BAR)

• DEEP FLUSHING: If the MRS-600HE System remains idle

for the programmed length of time, the control system
will automatically go into DEEP FLUSHING mode. During
this time, there will be flow to drain (reject). Remaining
flush time in seconds and storage tank water pressure
will be displayed.

DEEP FLUSHING...
XXXX S XXX PSI (BAR)

• RE-PRESSURIZE: At the start of the DEEP FLUSHING

operation, the system will repressurize to the normal
tank full pressure, then begin DEEP FLUSHING. Storage
tank water pressure will be displayed.

Under normal conditions, the pressure in the storage
tank will remain above the minimum allowable flush
pressure throughout the DEEP FLUSHING operation.
Once the DEEP FLUSHING operation ends, the system
returns to normal operation, but will not PRESSURIZE
until the storage tank water pressure drops below the
minimum allowable flush pressure. Once it runs and fills,
the system returns to operating within the normal “on”
and “off” pressure settings.

Programming Mode

The controller has several user accessible menus. This menu
“loop” allows for adjustment of several variable parameters.
The Controller has three (3) buttons below the display for
these adjustments. In most cases, a description of the button
function is shown in the digital display area.

Once you enter the programming mode, the controller will
save your last entry upon pressing ENTER. If an adjustment
is made without pressing ENTER, the controller returns to
the main screen and the adjustment will not be saved. If a key
is not depressed for about 25 seconds, the controller exits
programming mode and returns to the operational mode.

• Press and hold any key for three (3) seconds to enter

programming mode.

• II – Press the middle key to advance to “FLUSH TIME:
XXX S” screen. Press left or right key to advance to

whether psi or BAR will be the unit of measure used to
display the storage tank water pressure. Use the +/- keys
to adjust this value. Press ENTER to save the selected
value and advance to the next screen.

• TANK FULL P: XXX - This parameter determines the
pressure at which RO water production will stop, or turn
“off”. This setting is normally 100 psi (6.9 bar, 0.69 MPa).
Range is 70 – 100 psi (4.8 – 6.9 bar, 0.48 - 0.69 MPa) in five
(5) psi (0.3 – 0.4 bar, 0.03 - 0.04 MPa) increments. Use
the +/- keys to adjust this value. Press ENTER to save the
selected value and advance to the next screen.

• START DIFF.: XXX - This parameter determines the pres-
sure differential between the RO water production start
(“on”) pressure and stop (“off”) pressure. This setting is
normally 20 psi (1.4 bar, 0.14 MPa). Range is 10 – 25 psi
(0.7 – 1.7 bar, 0.07 - 0.17 MPa) in five (5) psi (0.3 – 0.4 bar,

0.03 - 0.04 MPa) increments. Use the +/- keys to adjust
