Reverse Osmosis Mineral Reduction System For Foodservice Applications
EV3123-42 Rev C OC12
INTRODUCTION
The Everpure MRS (Mineral Reduction System) is a pre-engineered,
pre-assembled Reverse Osmosis (RO) system designed to provide
high purity water for many applications, such as premium espresso,
coffee and blended beverages, 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 5) for normalized production.
Influent Water Characteristics
The following table lists the allowable operating range of various
water properties within which the MRS will function properly.
Total Dissolved Solids (TDS) 0-1500 PPM (0-1500 mg/L)
Hardness 0-10 grains (0-171 ppm)
pH 5-10
Chlorine10-3 PPM (0-3 mg/L)
Chloramines 0-3 PPM (0-3 mg/L)
Turbidity 0-1 NTU
Iron 0-1 PPM (0-1 mg/L)
1Reverse osmosis membrane lter used in this system will be damaged by chlorine. An
activated carbon lter has been provided with this system to protect the reverse osmosis
membrane from chlorine attack. Inuent chlorine should not exceed 3 mg/L.
The complete MRS consists of 5 major components:
Inlet booster pump.1.
5-Micron Pre-filter (optional).2.
Granular Activated Carbon Taste & Odor (TO) cartridge.3.
Reverse Osmosis (RO) membrane cartridge.4.
Calcium carbonate (CC) re-mineralization cartridge (CC models5.
only), or BW 4400 Sub-micron filtration cartridge (BL models only).
The optional 5-micron pre-filter removes suspended particles,
which can lead to premature plugging of the TO and/or RO
membrane cartridge. The TO cartridge removes most oxidizers, but
mainly reduces chlorine, preventing damage to the RO cartridge.
The RO 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. Depending on
the model, the permeate will do one of the following:
Systems without calcium carbonate (CC) cartridge - The permeatet
will pass through the cartridge head with by-pass plug, exiting to
service and/or enters the optional storage tank.
Systems with calcium carbonate (CC) cartridge - The permeatet
will pass through calcium carbonate cartridge, where re-
mineralization occurs. This cartridge reintroduces a metered
amount of minerals into the RO permeate. After remineralization,
the treated water exits to service and/or enters the optional
storage tank.
MRS-350BL Model Only - The permeate will flow into the sub-
micron filtration cartridge head. A metered amount of tap water will
mix with this permeate, and this blended water will pass through
the sub-micron filter. Once filtered, the water exits to service and/or
enters the optional storage tank.
The optional storage tank stores water that has been produced by
the RO System. This provides a water supply “buffer”, enabling the
system to provide reasonable volumes of product water during high
demand periods.

NOTES:
Please read this manual prior to installing and operating the system.t
For incoming water supplies that do not meet the influent watert
characteristics outlined on page 1, additional pre-treatment prior to
the system may be needed. System performance may be affected if
requirements are not met, including system output production and
cartridge change-out frequency.
If the supply pressure exceeds 80 PSI (5.5 bar), install a pressuret
reducing valve. Adjust the pressure reducing valve to the required
operating pressure, not to exceed 80 PSI (5.5 bar).
Consult with your local building inspector for approval andt
required permits to install this system. Additional equipment, such
as back-flow prevention devices, seismic restraint equipment, air
gaps, etc., may be required. Completed installation must meet all
local and national codes.
Do not connect the MRS system after any water filtration system,
unless specifically provided for use with the MRS.
UNPACKING AND INSPECTION
The MRS includes all the necessary fittings for installation. Lengths
of 1/4" (6.4 mm) tubing have been provided for connecting to the
wastewater/drain connection. Supply lines and distribution piping/
tubing are not included.
The MRS system is packaged as a complete unit in two cartons. At a
minimum, you should have the following:

Inspect the cartons for damage. Report any damage to freight
carrier immediately. Carefully unpack each item. Save the packaging
material temporarily, as it may be used to protect painted surfaces
during assembly.
SYSTEM ASSEMBLY
The MRS is configured as a two piece unit; with the processor
mounted on a vertical surface and the storage tank located nearby.
Locate the system in an area that is convenient to the inlet water
supply and drain facilities, with access for routing the product 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.
Processor Assembly Mounting
If the optional Pre-filter has been supplied, go to step to 2. If not1.
supplied, go to step 5.
Position the MRS processor assembly so the rear of the mounting2.
plate is accessible. Secure the wing bracket to the rear of the
mounting plate as shown Figure 1. Use the 5/16" hex bolts and
washers provided. Align the wing bracket so it is inward and
upward as far as possible – use a combination square to maintain
alignment. Tighten both bolts securely.
Attach Pre-filter head to Pre-filter bracket with 5/16” hex bolts,3.
nuts and washers provided.
Insert elbow fitting into solenoid valve inlet. Connect 3/8" (9.5 mm) OD4.
tubing between pre-filter outlet and elbow fitting on solenoid valve.
The processor framework has 6 mounting holes (3 keyhole slots,5.
3 standard) on 5.5" (139.7 mm) centers for securing to a stationary
vertical surface. Evaluate the mounting surface for its ability to
properly support the weight of the processor, approximately 40
lbs. (18.1 kg.), when in operation.

WARNING
Do not use screws smaller than #12 (5.5 mm) for
mounting the processor.
WARNING
Mounting surface may require reinforcement to
support processor safely. Hollow walls, drywall and other non-
structural surfaces are not suitable unless reinforced.
Piping/Tubing Connections
Refer to Figure 2 for views of the piping, with a description of major1.
components and connection points. These major components and
connections will be referred to in the following steps.
Prepare the plumbing to accept the RO system. It is recommended2.
that a three valve by-pass is installed to provide an uninterrupted
supply of water when the RO system requires service.
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 or 61
with a minimum pressure rating of 75 PSI (5.2 bar). The product
water will react with most metal piping, creating a corrosive
condition, in addition to imparting an objectionable taste. Plastic
pipe or reinforced 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.
Co3. nnect the inlet supply.
A. MODELS WITHOUT PRE-FILTER – See Figure 3. Connect to the
Inlet open port [3/8" (9.5 mm) JG] on the solenoid valve.
B. MODELS WITH OPTIONAL PRE-FILTER – See Figure 4. Connect
to the Inlet open port [3/8" (9.5 mm) JG] on the pre-filter head.
Connect the appropriate size and type of tubing/piping and4.
associated fittings to the outlet tee connection. Route the line(s) to
the equipment being serviced (i.e.; espresso, coffee, etc.).
Locate the storage tank directly below or adjacent to the processor5.
assembly. Be sure the mounting surface is capable of supporting
the weight of the tank when full (see specification table for
operating weights). Install an isolation valve and drain valve at the
storage tank, then connect a suitable length of 3/8" (9.5 mm) OD
tubing to the tank isolation valve. Route this section of tubing to the
main processor assembly. Connect the tubing to the elbow fitting or
open Y-connector port attached to the right-side of the processor.
Note: The storage tank pre-charge pressure should be checked
and adjusted when the storage tank is empty. The storage tank
pre-charge pressure should always be less than the system turn-
on pressure - typically 2-5 psi (0.14-0.34 bar) less.
Example: 25–40 psi (1.7–2.8 bar) system on-off pressure, 20 psi
(1.38 bar) tank pre-charge pressure.
Close the inlet, outlet and by-pass valves.6.
Locate the correct reject flow control assembly based on the7.
illustration below (A). Insert the reject flow control assembly into
the 1/4" (6.4 mm) OD tube (See A below). Insert the 1/4" (6.4 mm)
OD tube with reject flow control assembly into the elbow fitting
on RO head (See B below). Route the other end of the tubing to a
drain nearby, securing it temporarily. Allow an air gap at the drain,
following any applicable local codes. See Figure 5.

WARNING
Refer to Reject to Drain, Maximum under RO
Production in the Performance Table (page 5) to determine the
maximum gallon per minute waste flow rate. Verify drain has ample
capacity for this waste flow, plus all other sources of waste flow
sharing this drain.
Electrical Connections
The system is pre-wired at the factory. Verify that your supply
voltage matches the primary voltage on the transformer dataplate.
Available voltages are 115, 230 & 240 VAC. A ground fault protected
circuit rated at 10 Amps minimum is required. Plug-in power cord
when instructed to do so in the following section.
CARTRIDGE INSTALLATION AND ACTIVATION
Remove the outer shrink-wrap and protective closure from the1.
pre-filter (optional), TO, RO (MR) and CC cartridge (optional) or BW
4400 cartridge (optional).
If the optional Pre-filter has been supplied, go to step to 3. If not2.
supplied, go to step 4.
Locate the sump (clear bowl) for the pre-filter housing. Install the3.
pre-filter cartridge into the sump. Locate the O-ring in the small
parts pack. Lightly lubricate this O-ring with a food grade lubricant
and install it into the groove in the sump. Install the sump with pre-
filter and O-ring into the pre-filter head. Use the sump wrench to
tighten the sump securely.
Install the TO cartridge into the TO head (left-hand), following the4.
instructions on the cartridge.
Slowly open the inlet supply valve. Position a bucket underneath5.
the RO cartridge head (center) to collect the water. Apply power to
the system by plugging the power cord into the receptacle. Within
moments, water should begin to spill out of the RO head and into
the bucket. Carbon fines and air will be flushed out of during
this time. Flush until water runs clear (2-3 minutes typically). If
the bucket requires emptying, un-plug the power cord from the
receptacle to stop the flow, then empty the bucket. Reposition the
bucket and repeat the flushing operation as required. Once the
TO cartridge has been flushed, un-plug the power cord from the
receptacle.
Install the RO cartridge into the RO head, following the6.
instructions on the cartridge.
If the optional 7CC-BW or BW 4400 cartridge has been supplied,7.
go to step to 8. If not supplied, go to step 9.
Remove the plug from the 7CC-BW/BW 4400 cartridge head8.
(right-hand). Install the 7CC-BW or BW 4400 cartridge into the
head, following the instructions on the cartridge. If the optional
7CC-BW has been supplied, go to step to 9. If the optional BW 4400
cartridge has been supplied, open blend valve fully (See figure 5).
Go to step to 9.
Disconnect the tubing connecting the storage tank to the system9.
at the storage tank and route to a drain temporarily.
WARNING
Do not use this product water! It may contain a
preservative solution from the RO cartridge and should not be
consumed!
Apply power to the system by plugging the power cord into the10.
receptacle. Within moments, water should begin to exit the
storage tank tubing. If the optional BW 4400 cartridge has been
supplied, close blend valve after 3 minutes. Allow the system to
flush for at least 1 hour or until 5 gallons (18.9 l) of product water
has been produced. Un-plug the power cord. Re-connect the
tubing to the storage tank.
DISINFECTION
When flushing is complete, the storage tank and associated piping
must be disinfected, and then completely flushed. The steps for this
are outlined below.
Locate the 3/8" (9.5 mm) OD tubing that connects to the storage1.
tank. Disconnect the end which connects to the fitting at the
processor. Measure 1 ounce (29.6 ml) of 5.25% bleach for every 7.5
gallons (28.4 l) of storage tank capacity. Pour this volume of bleach
into the tube that leads to the storage tank. Re-connect this tube
to the fitting. Apply power to the system by plugging the power
cord into the receptacle. The booster pump should begin to run
and fill the storage tank.
Once sufficient water has entered the storage tank (more than 1/42.
full), demand treated water from at least one piece of equipment the
MRS is supplying water to. Once all of the air has been purged, and
a solid flow of water is observed, stop the flow at the connected
equipment. Purge the air from all remaining pieces of connected
equipment by demanding water from each one individually.
Allow the storage tank to fill until the booster pump turns off.3.
Allow the chlorinated water to remain in the storage tank and
distribution piping for 10 minutes.
Un-plug the power cord. Drain the storage tank by demanding4.
water downstream and allow the storage tank to drain. Once the
storage tank is empty, stop demanding water downstream.
Apply power to the system by plugging the power cord into the5.
receptacle. Once sufficient water has entered the storage tank
(more than 1/4 full), demand treated water from at least one piece
of equipment the MRS is supplying water to. After 5 minutes,
stop the flow at the connected equipment. Flush the lines to each
remaining piece of connected equipment by demanding water from
them for 2 minutes each.
Allow the storage tank to fill until the booster pumps turns off.6.
Un-plug the power cord. Drain the storage tank by demanding7.
water downstream and allow the storage tank to drain. Once the
storage tank is empty, stop demanding water downstream
Repeat steps 5-7 until no residual chlorine odor is detected from the8.
water exiting the storage tank drain valve or connected equipment.
BLEND VALVE ADJUSTMENT - BL MODELS ONLY
A blend valve (below pump) and sample valve (on right-side of
processor where tank connects) have been provided to adjust and
measure the TDS level of the treated water. Adjustment should be
made when the system is processing water, and the storage tank is
isolated. When making adjustments, allow the line to flush briefly
after an adjustment is made, collect a 16 oz. (473 ml) sample, then
measure the TDS with a calibrated TDS meter. Close the blend valve
to reduce the TDS, open it to increase the TDS. See figure 5 for
blend valve location.
PLACING THE MRS INTO SERVICE
Once the cartridges have been activated, the storage tank &
distribution piping sanitized, the MRS can be placed into service.
During normal operation, the valves on the MRS should be in the
following positions:
System inlet and outlet valves – openA.
System by-pass valve – closed.B.
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 6 to record this information.
PRESSURE SWITCH ADJUSTMENT
The on-off operation of the system is controlled by a pressure
switch. The factory setting is approximately 25 psi (1.7 bar) ON - 40
psi (2.8 bar) OFF. A 5/64” (2 mm) hex key can be used to adjust the
pressure setting. Clockwise rotation of the hex screw increases the
operating pressure and counter-clockwise rotation decreases the
operating pressure. See Figure 5.
Whenever making adjustments to the pressure switch, check the system
ON-OFF operation and adjust the storage tank pre-charge as needed.
The storage tank pre-charge pressure should always be less than
the system turn-on pressure - typically 2-5 psi (0.14-0.34 bar) less.
Example: 25–40 psi (1.7–2.8 bar) system on-off pressure, 20 psi (1.38
bar) tank pre-charge pressure.
