Introduction
The Everpure MRS-200 System is apre-engineered, pre-assembled reverse osmosis system
designed to provide highpuritywater formanyapplications, such as premium espresso, coffee
and blended beverages, to name afew.It combines anumber ofwater treatmenttechnologies
into one easyto install package. The system provides superior protection against taste and odor
causingcontaminants while removingdirt, particulates and dissolvedsolids that can foul or
scale equipment.
Please read this manual prior to installingandoperatingthe system.
Initial Outlet Water Production
200 gal per day(52Liters per day) @ 60psig(340 kPa), 77oF(25oC)
Water production depends on supplywater pressure andtemperature.
TABLE 1 - Influent WaterCharacteristics
Pressure160-100 psig (414-690 kPa)
Temperature 33-100°F (1-38°C)
Total Dissolved Solids (TDS)20-2500 PPM (0-2500 mg/L)
pH 5-10
Chlorine30 PPM (0mg/L)
Chloramine 0-3 PPM (0-3 mg/L)
Turbidity 0-10 NTU
Iron 0-1 PPM (0-1 mg/L)
1. For units with inlet pressure lower than 50 psig aboosterpump is recommended.
2. Where TDS exceeds 600PPM (600 mg/L) andthe pressureless than 60 psig, abooster pumpis recommended.
3. The reverse osmosis membrane filter used in this system will be damaged by chlorine. An activated carbon filter has
been provided with thissystemto protect the reverseosmosismembrane fromchlorine attack. Influent chlorine
should not exceed 3 mg/L.
TheMRS-200 System consists of seven major components:
1. Gallon/Calendar monitor.
2. 5-Micron Pre-filter.
3. Granular Activated Carbon Taste& Odor (TO) cartridge.
4. Reverse Osmosis (RO) membrane cartridge.
5. Filtered Water Blend Valve.
6. 15-gallon atmosphericStorage Tank.
7. Constant pressure product water Re-pressurization Pump.
The MRS-200 containsall the necessarypiping,valves and fittings pre-assembled onto afloor-
standingrack.Lengthsof¼” and 3/8” tubingare provided for connectingto the
wastewater/drainand sample/flushinglines.
The 5-micron pre-filter removes suspended particles, which can lead topre-mature plugging of
the TO and/orRO membrane cartridge(s). The TO cartridge removes most oxidizers, but mainly
reduces chlorine, preventing damagetotheRO cartridge. The ROcartridgecontains asemi-
permeable reverse osmosis membrane.Here, most dissolved impurities are separated fromthe
water and flushed downthe drain. The water thatis ableto pass throughthe membrane,which
is verylowin dissolvedimpurities,enters the storagetank.This is referred to as RO water or
product water. In certain applications, some filtered water is mixed(viathe filtered water blend
valve) with theproduct water toattain a specific level oftotal dissolved solids (TDS).

The storagetankstores water that has been produced byboth the RO System and the filtered
water blend valve. It provides awater supplybuffer enablingthesystem to provide reasonable
volumes ofproduct water during highdemand periods.
The product water re-pressurization pump develops and maintains the pressure required for
deliveringthe water from thestorage tank totheconnected equipment.
Aunique cartridgemonitor/alarm module has been included. This device can be set to provide
simultaneous water throughputand operatingtime indications over easilyselectable ranges.
This monitor helpsin determining cartridgechange-out schedules.
Pre-Installation Checklist
1. ____ Can the unit be mountedwithin areasonable distance ofthe water supplyand
drain facilities?
2. ____ Are two115 VAC GFIC protected receptacles available for connectingthe 115
VAC/24 VAC transformer andproduct water re-pressurization pump?
3. ____ Is there adequate clearance and support to install the unit and permit access for
maintenance? Thesystem will weighapproximately175 pounds when the
storagetank is full.
4. ____ Does theinlet water supplymeet the requirements listed below? 1
 A minimum of 1.0 GPMat 50-100 psi pressure on a consistent basis
 Less than500ppm TotalDissolved Solids
 Less than10GPG of hardness
 pH level between 7.0-9.0
 Turbidityless than1 NTU
1. Incoming water suppliesthat do not meet these requirements mayneed additional pre-treatment prior to the system.
Systemperformance may be affected if requirements are not met, including systemoutput production and cartridge
change-out frequency. Optional inlet booster pumpsare available to increase supply water pressure and system
production.
SystemInstallation
1. Locate the MRS-200 system in an area
that is convenient to the inlet water
supplyand drain facilities, with access
for routingthe product water
tubing/pipingto the equipment. Also
consider ease ofservice when selecting
a location.
2. Refer to Figure 1 for assemblingthe four
legsto the shelf. Insert each legfully
with the twohalfsleeves provided.
Adjust the levelingbolt(s) asrequired
until the shelfis stable and levelin all
directions.

3. Referto Figure 2for aviewofthe complete assembly,with adescription ofmajor
components and connection points.Place themain unit on the shelf, positioning the
cartridgeheads directlyover the cutout area.Insert acable tie intoone ofthe holes in the
baseplate and throughthe wire “slats” in the shelf, makingasecure loop. Do this with all
four corners of thebaseplate.
