Installation and Operation Guide
INTRODUCTION
The Everpure ENVI-RO™ Mineral Reduction System is a preengineered, pre-assembled Reverse Osmosis (RO) system designed
to provide high purity water for multiple applications, such as
premium espresso, coffee, blended beverages and steam, 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 8) for normalized production.
Influent Water Characteristics
The following table lists the allowable operating range of various
water properties within which the ENVI-RO™ will function
properly.
Total Dissolved Solids (TDS) 0-1,000 ppm (0-1,000 mg/I)
pH 5-10
Chlorine
1
Chloramines 0-3 ppm (0-3 mg/I)
Turbidity 0-1 NTU
Iron 0-1 ppm (0-1 mg/I)

Reverse osmosis membrane lter used in this system will be damaged by chlorine. An
activated carbon lter should be provided with this system to protect the reverse osmosis
membrane from chlorine attack. Inuent chlorine should not exceed 3 mg/I.
The system consists of 5 major components:
2SR-BW Water Conditioning cartridge1.
Dual-Head booster pump2.
MR-600 Reverse Osmosis (RO) membrane car tridge.3.
6-Gallon RO Water Storage Tank4.
Control System with Power Supply5.
The 2SR-BW Water Conditioning cartridge contains media that
reduces the scaling tendency of hard water minerals found in many
water supplies, extending RO membrane life.
The Dual-Head booster pump increases the inlet pressure to
maintain consistent permeate production, plus eliminates backpressure on the permeate output. This innovative approach to both
boosting and eliminating back-pressure allows for maximum system
efficiency.
The MR-600 RO membrane 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.
Once the RO water is produced, it is stored in the 6-Gallon RO Water
Storage Tank. This tank serves t wo key functions; 1) It acts as a
buffer between the system and the connected equipment, providing
ample volumes of water instantaneously, 2) It reduces the on-off
cycling of the RO system, which produces better quality water, and
prolongs the system’s life.

RECOVERY ADJUSTMENT
Measure the raw water TDS. Refer to Table 1 on page 6. Find 1.
the TDS range in the column labeled “Raw Water TDS” that
corresponds to your TDS measurement. Read across that row
to determine maximum recovery, permeate to reject ratio and
permeate/reject volumes.
Using 2 - 32 oz. or 1,00 0 ml graduated containers, apply power 2.
to the system and collect the permeate flow (from storage tank
drain valve) in one container and the reject (WASTE) flow in the
second container. Compare the volumes collected to the data
shown in the table. Adjust the reject needle valve to increase or
decrease the flow. Empty the containers and collect additional
samples.
Once the ratio of Permeate-to-Reject closely matches the data 3.
in Table 1, the Reject Only volume requires measurement . Using
only 1 graduated cylinder, collect the reject flow for 1 minute.
NOTE: Reject volume in 1 minute may exceed 32 oz./1,000 ml. If
so, use a larger container, or collect samples in multiple
containers and add all collected volumes together.
Unplug power cord. Close storage tank drain valve.4.
Return to page 6, Table 2. Find the volume range in the column 5.
labeled “Reject Volume per Minute” that corresponds to the
volume collected in Step 4. Read across that row to identify the

DISINFECTION
When car tridge activation and recovery adjustments are complete,
the storage tank and associated piping must be disinfected, then
completely flushed. The steps for this are outlined below.
Locate the 3/8" OD tubing that connects to the inlet (left side) 1.
of the storage tank. Disconnect the end which connects to the
elbow fitting at the processor. Measure 1 ounce of 5.25% bleach
for ever y 7.5 gallons of storage tank capacity. Pour this volume of
bleach into the tube that leads to the storage tank. Re-connect
this tube to the elbow 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 suf ficient water has entered the storage tank (more 2.
than 1/4 full), demand treated water from at least one piece of
equipment the ENVI-RO 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.
Unplug the power cord. Drain the storage tank by demanding 4.
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 the 5.
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 ENVI-RO 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.
Unplug the power cord. Drain the storage tank by demanding 7.
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 8.
the water exiting the storage tank or connected equipment.
DUAL OUTLET AND BLEND ADJUSTMENT
The ENVI-RO system is capable of producing t wo water qualities,
which are detailed below.
The outlet marked “STEAMER” provides water directly from the •
RO Membrane. The TDS of this water is ver y low, ideally suited
for applications such as flash steamers and other equipment that
“boils away” the water. This outlet requires no adjustment.
The outlet marked “COFFEE” can produce a wide range of water •
qualities. It combines or “blends” two sources of water; 1)
directly from the RO Membrane and, 2) filtered water containing
the same level on mineral content as the raw (feed) water. The
following text describes the adjustment of this feature.
Open the feedwater blend valve (FBV) and dilution blend 1.
valve (DBV) fully. See Figure 6 for location of these valves.
Demand flow on the “COFF EE” line. The flowrate should 2.
equal the maximum expected demand of all connected
equipment.
Access the “Cof fee TDS” view screen on the controller to 3.
observe a real-time reading of the TDS quantity in the water
flowing to the “COFFEE” line.
Compare TDS value on controller to application requirement. 4.
If controller reading is higher than requirement, slowly close
FBV until TDS value is met. If controller reading is lower than
requirement, slowly close DBV until TDS value is met.
Figure 6. RO Blend Valve Locations
PLACING ENVI-RO INTO SERVICE
Once the car tridges have been activated, the storage tank and
distribution piping sanitized, the ENVI-RO can be placed into ser vice.
During normal operation, the valves on the ENVI-RO should be in the
following positions:
System inlet and outlet valves – openA.
System by-pass valves – 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 9 to record this information.
OPERATION
During normal operation, a continuous supply of water must be 1.
available to the system.
The system inlet and outlet valves must be open, the sample 2.
outlet and flushing valves must be closed and the drain line must
be unrestricted.
