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)
pH 5-10
Chlorine 1 0-3 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)
1 Reverse osmosis membrane filter used in this system will be damaged by chlorine. An
activated carbon filter has been provided with this system to protect the reverse osmosis
membrane from chlorine attack. Influent 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 (optional). 5.
The optional 5-micron pre-filter removes suspended particles, which
can lead to pre-mature 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 permeate
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 permeate will
pass through calcium carbonate cartridge, where re-mineralization
occurs. This cartridge reintroduces a metered amount of TDS level
of the RO permeate. After remineralization, the treated 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.
A unique cartridge monitor/alarm module is available. This device
can be set to provide simultaneous water throughput and operating
time indications over easily selectable ranges. This monitor helps in
determining cartridge change-out schedules.

Pre-Installation checklist
1. Can the unit be mounted within a reasonable distance of
the water supply and drain facilities?
2. Is there an un-switched 115 VAC GFIC (ground fault
interrupter circuit) protected receptacle available for powering
the system?
3. Is there adequate clearance and support to install
the unit and permit access for maintenance? The total system
weight will vary based on model and storage tank selected. See
specification table for approximate operating weights.
4. Does the inlet water supply meet the requirements listed
below?
A minimum of 25 PSI pressure on a consistent basis a.
Less than 1,500 ppm of Total Dissolved Solids (TDS) b.
Less than 10 GPG of water hardness c.
pH level between 7.0-9.0 d.
Turbidity less than 1 NTU e.
