Everpure MRS-100 Installation And Operation Manual

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.

The following table lists the allowable operating range of various
water properties within which the MRS will function properly.

Reverse osmosis membrane filter used in this system will be damaged by chlorine. An
1
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:
1. Inlet booster pump.
2. 5-Micron Pre-filter (optional).
3. Granular Activated Carbon Taste & Odor (TO) cartridge.
4. Reverse Osmosis (RO) membrane cartridge.
5. Calcium carbonate (CC) re-mineralization cartridge (CC models
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 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 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.

Reverse Osmosis Mineral Reduction System For Foodservice Applications
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.

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 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 in the tables
above?
