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

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

 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.

4. Watersupplies with adynamic operatingpressure of50 PSI orless require the useofthe

booster pump to increase production. Watersupplies with adynamic operatingpressure

greater than 50 PSI generallydo not require the addition ofabooster pump, unless certain

site specific conditions prevent the system fromattainingthe rated production output without

it. Thebooster pumpincreases theincoming pressure byapproximately45 PSI.

Do not install the inlet booster pump on water supplies with adynamic pressure in

excess of 75 PSI.

Do not connectthe MRS-200 system afteranywater filtrationsystem, unless

specificallyprovided for use withtheMRS-200.

Ifaboosterpump is required, refer to Figure 4. Assemble amale elbowfittingto thepump
