Everpure ENVI-RO User Manual
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
correct capillary tube combination.
Locate the correct capillary tubes from the par ts kit. Remove the 6.
2 - 1/4"OD tubes from the upper Y-connector. Insert the capillar y
tubes into each line and re-assemble to the Y-connector.
NOTE: In some cases, the capillary tube requires trimming. Use a
SHARP utility knife to cut the tube cleanly without tearing or
crushing the tube.
Remove Reject Needle valve assembly and reconnect 3/8" tube. 7.
Plug-in power cord. Allow system to run and fill tank. This will
take 5-10 minutes.
Refer to Table 2 again. Under the column labeled “Flush Time in 8.
Seconds”, find the value that corresponds to the Raw Water TDS.
Enter this value in the controller under “FLUSH TIME X1”. Adjust
“FLUSH INT X2” to 1.5 Hours.
