ENVI-RO™ High Efficiency Reverse Osmosis System  
Mineral Reduction System For Foodservice Applications  
IntroductIon  
The Everpure ENVI-RO™ Mineral Reduction System is a pre-  
engineered, 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.

Pre-Installation checklist  
1. Can the unit be mounted within a reasonable distance of the  
water supply and drain facilities?  
5. Control System with Power Supply  
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.  
2. Is there an un-switched 115 VAC GFIC (ground fault interrupter  
circuit) protected receptacle available for powering the system?  
The Dual-Head booster pump increases the inlet pressure to  
maintain consistent permeate production, plus eliminates back-  
pressure on the permeate output. This innovative approach to both  
boosting and eliminating back-pressure allows for maximum system  
efficiency.  
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 listed below?  
a. A minimum of 25 PSI pressure on a consistent basis  
b. Less than 1,000 ppm of Total Dissolved Solids (TDS)  
c. pH level between 7.0-9.0  
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.  
d. Turbidity less than 1 NTU  
Once the RO water is produced, it is stored in the 6-Gallon RO Water  
Storage Tank. This tank serves two 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.

3. Refer to figure 1 for mounting bracket details. Position the top  
row of holes 1-9/16" inches below the top of the processor when  
installed. Install the wall mount bracket to a suitable vertical  
surface. Use no less than 4 - #12 fasteners to secure the bracket  
to the surface.

5. Measure and install 2 - #12 fasteners on 16" centers to engage  
the top edge of the processor backplate - leave 1/4" gap. Lift  
the processor and “hook” the key-hole slots on the processor  
backplate. Tighten the 2 fasteners.  
6. Install 2 - #12 minimum fasteners in the 2" wide slots along the  
bottom edge of the processor backplate.  
Piping/tubing connections  
1. Refer to figure 2 and the drawing on Page 14 for general views  
of the piping, with a description of major components and  
connection points. These major components and connections  
will be referred to in the following steps.  
2. A parts kit has been provided, which includes valves and tees to  
configure a system by-pass. Assemble the parts to the system  
using the example shown in figure 3.  
3. Prepare the plumbing to accept the RO system.  
note: The product water tubing/piping and associated fittings  
connecting the RO product outlet to the equipment being  
serviced should be food grade material that meets NSF  
Standard 51 or 61 with a minimum pressure rating of 100-PSI.  
The product water may react with metal piping, creating a  
corrosive condition, in addition to imparting an objectionable  
taste. Plastic pipe or reinforced tubing are generally very  
good choices for RO water distribution materials. The size of  
the product water tubing/piping should be 3/8" ID minimum.  
Distances of 25 feet or greater from the RO to the equipment  
being serviced should be 1/2" ID minimum.  
4. Shut-off the supply of water to the existing filtration system, and  
relieve pressure. Connect a line from the treated water outlet of  
the filtration system to the inlet of the ENVI-RO system.  
5. Connect the appropriate size and type of tubing/piping and  
associated fittings to the corresponding ENVI-RO outlet  
connection. Route the line(s) to the equipment being serviced  
(i.e.; espresso, coffee, etc.). Close the inlet, outlet and by-pass  
valves. Apply pressure to the existing filtration system and place  
it back into service.  
figure 4. Reject Y-Connector Detail  
6. Check the storage tank pre-charge pressure. It should only be  
checked and adjusted when the storage tank is empty. A 30 psi  
pre-charge pressure is required.  
7. Connect a 3/8" OD tube to the reject Y-connector (labeled  
WASTE) located in lower right corner of processor. Route the  
other end of the tubing to a drain nearby, securing it properly.  
Allow an air gap at the drain, following any applicable local and  
national codes. See figures 2 and 4.  
WARNING  
Refer to “Reject to Drain, Maximum” under RO  
Production in the Performance Table (page 8) to  
determine the maximum gallon per minute waste  
flow rate. Verify drain has ample capacity for this  
waste flow, plus all other sources of waste flow  
sharing this drain.  
8. Locate the needle valve from the parts kit. Attach a short section  
of 3/8" tubing to this valve.  
note: This assembly will be used to adjust the system recovery in  
the following section, then removed.  
9. Remove the 3/8" tube from the reject Y-connector and install the  
needle assembly between the reject Y-connector and 3/8" tube.

2. Using 2 - 32 oz. or 1,000 ml graduated containers, apply power  
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.

3. Once the ratio of Permeate-to-Reject closely matches the data  
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.  
4. Unplug power cord. Close storage tank drain valve.  
5. Return to page 6, Table 2. Find the volume range in the column  
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.  
6. Locate the correct capillary tubes from the parts kit. Remove the  
2 - 1/4"OD tubes from the upper Y-connector. Insert the capillary  
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.  
7. Remove Reject Needle valve assembly and reconnect 3/8" tube.  
Plug-in power cord. Allow system to run and fill tank. This will  
take 5-10 minutes.  
8. Refer to Table 2 again. Under the column labeled “Flush Time in  
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.

dual outlet and blend adjuStment  
When cartridge 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.  
The ENVI-RO system is capable of producing two water qualities,  
which are detailed below.  
The outlet marked “STEAMER” provides water directly from the  
RO Membrane. The TDS of this water is very low, ideally suited  
for applications such as flash steamers and other equipment that  
“boils away” the water. This outlet requires no adjustment.  
1. Locate the 3/8" OD tubing that connects to the inlet (left side)  
of the storage tank. Disconnect the end which connects to the  
elbow fitting at the processor. Measure 1 ounce of 5.25% bleach  
for every 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.  
2. 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. 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.  
3. Allow the storage tank to fill until the booster pump turns off.  
Allow the chlorinated water to remain in the storage tank and  
distribution piping for 10 minutes.  
4. Unplug the power cord. Drain the storage tank by demanding  
water downstream and allow the storage tank to drain. Once the  
storage tank is empty, stop demanding water downstream.  
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.  
1. Open the feedwater blend valve (FBV) and dilution blend  
valve (DBV) fully. See figure 6 for location of these valves.  
2. Demand flow on the “COFFEE” line. The flowrate should  
equal the maximum expected demand of all connected  
equipment.  
3. Access the “Coffee TDS” view screen on the controller to  
observe a real-time reading of the TDS quantity in the water  
flowing to the “COFFEE” line.  
4. Compare TDS value on controller to application requirement.  
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.  
5. Apply power to the system by plugging the power cord into the  
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.  
figure 6. RO Blend Valve Locations  
6. Allow the storage tank to fill until the booster pumps turns off.  
7. Unplug the power cord. Drain the storage tank by demanding  
water downstream and allow the storage tank to drain. Once the  
storage tank is empty, stop demanding water downstream  
8. Repeat steps 5-7 until no residual chlorine odor is detected from  
the water exiting the storage tank or connected equipment.  
PlacIng enVI-ro Into SerVIce  
Once the cartridges have been activated, the storage tank and  
distribution piping sanitized, the ENVI-RO can be placed into service.  
During normal operation, the valves on the ENVI-RO should be in the  
following positions:  
A. System inlet and outlet valves – open  
B. System by-pass valves – closed.  
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  
1. During normal operation, a continuous supply of water must be  
available to the system.  
Dilution Blend
