INTRODUCTION
Leveraging proprietary technology, the Pentair® Everpure® EZ-RO system
provides high quality water for applications, such as premium espresso,
coffee, ice, and blended beverages. The system combines multiple water
treatment technologies, providing superior protection against taste and odor-
causing contaminants.
The system meets ice machine, espresso, coffee and tea equipment and customer
water quality standards, known to significantly reduce scale and corrosion
problems due
to high TDS†, water hardness†, and chlorides while reducing dirt†,
particulates† and dissolved solids that may foul or scale equipment or may
contribute to corrosion.
When installed, serviced and maintained according to Pentair Everpure installation and operation instructions.
These contaminants are not performance tested or certified by NSF®.
GENERAL INFORMATION
EZ-RO for Hardness Minerals and Undesirable TDS
Unfiltered water can degrade equipment and affect product taste, which hits
food service business owners two ways—operational costs and profit loss.
Like most reverse osmosis systems, EZ-RO reduces contaminants before they
enter the equipment and the end user experience.
EZ-RO reduces high TDS (Total Dissolved Solids) on a molecular level. It then
adds back calcium and magnesium from the mineral addition cartridge and allows
you to blend back additional TDS to your specific requirements with the built
in blend valve and TDS meter, making it ideal for ice machines, coffee, tea,
and espresso brewing equipment. It achieves next level quality water through
its ease of use from install through on-going maintenance, water efficiency,
and expandability.
Quality System for Quality Water
EZ-RO features a compact body with a built-in bypass and flush valves, so you
cut down on steps during install and servicing.
From there, we ensure seamless performance. The reimagined RO solution filters
contaminants—all while adding back the minerals you want.
This tailored blending process moderates the right amount of dissolved
minerals to achieve your desired final water quality.
Easy – With more accessible parts and no extra SKUs, this all-inclusive system
makes specification, installation, and maintenance easier.
It’s universal, so contractors know what they’re dealing with after one
encounter.
Expandable – Our system grows with the business by design.
The system is compact, yet customizable to expand no matter how it’s
installed—wall mounted, free standing or under the counter.
Upgrade filters or tanks as operational needs increase, as available.
Efficient – The small footprint optimizes space.
The remineralization technology safeguards the investment to avoid premature
replacements as the high output membrane recovers up to 50% water.

Tubing Preparation
The tubing outside must be free of nicks or gouges.
Cut tubing with a proper tube cutter for a clean, round cut.
After cutting, make sure the end of the tube is round. Fix if needed.
Mark on the tube the depth that it should go in. This will help you see when the tube is fully inserted.
Size and color of tube| Insertion depth to
mark
---|---
1/4″ black| 1/2″ to 5/8″
3/8″ green| 3/4″ to 7/8″
1/2″ blue| 1″ to 1-1/8″
To Remove Tubing
Press collet in to release the grippers while pulling out the tubing.
To Attach Tubing
To lubricate, moisten end of tubing with fresh water.
Push tubing straight in.
You will feel resistance when the tubing meets the O-ring.
Keep pushing past the resistance until the tubing rests against the stop. Check the mark that you made on the tube to make sure the tube is inserted far enough.
WALL-MOUNT INSTALLATION
Locate system near electrical outlet, equipment, drain, and water source.
- Do not block access to controls and filters.
- Leave at least 3″ clearance below the cartridges for removal.
- Mount processor where it is well-supported.
- Using appropriate wall anchors or screws, fasten anchors into concrete or screw directly into studs beneath wall board. If using concrete fasteners, follow manufacturer’s instructions.
NOTE: If mounting on drywall, locate studs. Make sure that at least two of the anchors will be fastened into a stud.
- Remove RO processor top cover by loosening Phillips screw in the back. Using a level, draw a line where the top or bottom of the bracket will be. Hold the RO processor on the line in the position it will be mounted and mark the four holes on the bracket.
- Secure RO processor to wall using appropriate wall anchors. Put in screws with enough clearance to install the bracket.
- How to use the supplied drywall/stud anchors:
- Using #2 Phillips screwdriver, press drywall/stud anchor tip slightly into drywall. Applying pressure, turn anchor. If wood stud is hit, increase pressure. Continue turning anchor until flush.
- Insert screw into anchor and mostly screw it in.

IMPORTANT: Do not plug in to power yet.
OVERALL VIEW OF COMPLETED INSTALLATION
SYSTEM STARTUP AND FLUSHING PROCESS
REJECT FLOW RESTRICTOR SELECTION
-
Install prefilter into far left position and mineral addition cartridge in middle position. Align cartridge lugs with heads in bracket. Press up and twist a quarter turn.
-
Make sure the membrane plug is installed.The processor comes with a pre-installed standard reject flow restrictor (gray). Water conditions and RO membrane filter size will determine what color flow restrictor may be required to have your EZ-RO system operating the most efficiently.
Record the feed water conditions of incoming TDS measured in ppm (parts per million) and the incoming water pressure measured in psi.
Then see the “Reject Flow Restrictor Chart” on page 13. Follow chart per system size EZ-375 or EZ-650.
If the chart recommends using the gray flow restrictor, skip steps 3 through -
The reject flow restrictor that will need to be replaced is located on the left side of the 1/4″ Tee fitting on the top of the processor connected to the black tubing.
-
Press the gray collet into the fitting and pull the left black tube away from the 1/4″ Tee fitting. See “Using Push-to-Connect Fittings” on Page 7. Pull out the gray capillary flow restrictor. This task may require small pliers.
-
After reviewing the “Reject Flow Restrictor Chart”, choose from the bag located with the manual the color of flow restrictor that best fits your water requirements. Colors included: green, blue, white, orange. (Gray is pre-installed.)
-
Insert the selected flow restrictor into the 1/4″ black tubing. Firmly insert black tubing into 1/4″ Tee fitting. FLUSHING PRE FILTERS
-
Open the reject flush valve.
It’s the side middle blue handle.
Open = pointing down. -

It’s the side bottom blue handle.
Closed = pointing left. -
Turn the RO processor valves to the following positions: Inlet valve: top black handle pointed down (open). Outlet valve: bottom black handle pointed to right
(closed). -
Turn on incoming feed water from source. After step 11 connecting to power:
- Water will begin to fill RO processor and prefilter.
- Pressure gauge will show increase pressure.
- Check for any leaks. Shut off incoming water and repair leaks if required. Restart step 10.
-
Connect tank power supply to wall outlet.
-
Check system status light: yellow indicates tank is at low level.
- RO Processor will power solenoid and water will begin to flow from drain and through the TO TANK line that is secure in the sink.
- Check for any leaks. Shut off water and repair leaks if required. Turn incoming feed water back on when corrected.
NOTE: The pump might turn on quickly and then it should turn off. If pump continues to run, disconnect power, check ATM tank to ensure the low level sensor is connected and no water is in tank. Reconnect power. See Troubleshooting.
5 MINUTE FLUSHING OF PREFILTER AND MINERAL ADDITION CARTRIDGE.
-
Flush prefilter and mineral addition cartridge for five minutes or until water runs clear.
- With power on, and solenoid valve open, flushing will proceed through reject outlet and through TO TANK port at this time.
REMOVE SYSTEM PRESSURE
- With power on, and solenoid valve open, flushing will proceed through reject outlet and through TO TANK port at this time.

TWENTY-FOUR HOUR MEMBRANE FLUSH
-
Make sure system pressure is down to 0 psi.
-
Remove the membrane plug. Rotate left and pull down.
-
Store plug under system cover for future use.
-
Install supplied RO membrane cartridge (EZ-375 or EZ-650) into the farthest right position.
-
Turn on incoming feed water from source.
- Water will begin to fill the RO processor.
- Water will start to run from reject outlet at full flush and TO TANK port tubing.
- Ensure both lines are secure with water flowing to drain or sink.
-
Flush the system through reject outlet and TO TANK port for one hour.
-
After one hour close the reject flush valve.
It’s the side middle blue handle.
Closed = pointing left.
At this time, turn blending valve fully closed by rotating knob clockwise until it stops. -
Continue to flush for another 23 hours.
-
Recommended: Using a graduated cylinder, record the optimized water flow and reject flow in ounces/minute or milliliters/minute.
Fill the graduated cylinder for one minute for each. Record the values here:
Optimized water____oz. or ml /min Reject water____oz. or ml /min
NOTE: Reject water volume in one minute will probably exceed 32 oz./1,000 ml. Use a large container or collect samples in multiple containers and add all of the collected volumes together.
ATM TANK FILL AND PUMP STARTUP
-
After 23 hours, stop system flush by closing inlet valve: rotate 90 degrees so that it points to the right.
-
Run 3/8″ blue TO TANK tubing line to TANK INLET through bracket so tank cover will close correctly. Cut tubing to length allowing some slack for maintenance of system and tank.
-
Install the end of the 3/8″ blue TO TANK tubing line to atmospheric tank ATM TANK INLET.
-
On RO processor, turn inlet valve to open position (pointing down).
-
On tank, open ATM TANK INLET valve. Check for any leaks at inlet valve or float switch. Repair if required.
-
Unplug tank power supply.
-
Open the ATM tank’s 6″ lid/access port and insert optimized outlet 1/2″ gray hose into tank to add water to the ATM tank.
-
Turn the inlet valve and outlet valve to bypass position (both pointing to the right). Hold hose securely.
-
Add water to the tank until it is 1/4 full.
-
Once ATM tank is filled to approximately 1/4 full, open inlet valve (pointing down) on the RO processor. Water should stop flowing from gray hose. Reattach gray hose to clean sink for flushing the buffer tank. IMPORTANT: Keep outlet valve on the RO processor in closed position (pointing to the right).
-
Connect power supply to wall outlet.
-
Pump should begin to run and will flow water from the pump into the buffer tank. The ATM tank systems status should show a flashing green light. Check to make sure ATM tank outlet valve is in the open position.
-
If light is flashing yellow, there is a possibility that the low level sensor did not recognize water at first power up. The flashing yellow light will flash for five minutes then pump will activate again.
-
If light is solid yellow, that indicates that the low-level sensor does not see any water and the tank will need to be filled higher before the pump will activate.
-
Pump will shut down when buffer tank and line reach 60 to 70 psi of pressure.
NOTE: It could be helpful to quickly open and close the outlet valve on the RO processor to release any trapped air in line. Two to three times should be fine. Release trapped air and water out of the optimized outlet ½” gray tubing into the drain or sink. -
Water will be filling the ATM tank now also from RO processor. When filling without pump, system status light will be blue.
-
-
Let ATM tank fill until tank is full. ATM tank system status light turns from blue to green.
- System status solid green indicates ATM tank is full and high-level sensor is met.
NOTE: If water does not stop and system status does not turn green, check high level sensor connection. See troubleshooting guide.
- System status solid green indicates ATM tank is full and high-level sensor is met.
FLUSH BUFFER TANK
-
Unplug tank power supply.
-
Slowly open outlet valve on RO processor to begin to drain buffer tank water through gray hose attached to sink. When flow rate from the outlet hose stops, buffer tank is empty.
-
Close outlet valve on RO processor when buffer tank is empty.
NOTE: Steps 2 and 3 can alternatively be completed using the ATM TANK OUTLET VALVE. -
Connect power supply to wall outlet. Pump should begin to run and fill buffer tank as in step 11 on previous page.
-
REPEAT STEPS, 1 through 4 a total of 5 times to flush buffer tank. After 5th time flushing buffer tank, move to step 6.
-
Open outlet valve on RO Processor to allow water to drain from ATM tank completely. Pump will be running water this entire time.
-
Pump should shut down when tank is near empty or low-level sensor has been exposed. System status light should be yellow. Drain buffer tank to empty also – water flow from optimized outlet will come to near stop.
NOTE: Water will be filling the ATM tank From the RO processor at this time. This is expected.- Once low-level sensor sees water again, the system status light will turn to blinking yellow indicating that the pump is on delay for five minutes.
-
Close outlet valve on RO processor to allow ATM Tank to continue to fill.
- Water will be filling ATM tank from ATM TANK INLET
- ATM tank system status will indicate low level –once water meets low level switch – pump delay will begin with flashing yellow light. (Pump delay is five minutes.)
- Pump will begin to cycle to fill ATM buffer tank and will probably cause low level situation repeatedly until ATM tank Outlet line pressurizes to 70 to
60 psi. This is normal. Fill ATM tank full. System status will indicate a solid green light and drain flow/to tank water flow will stop.
-
Let ATM fill until tank is full. ATM tank system status light turns from blue to green.
-
Repeat Steps 6 through 8 for final flush of ATM tank. ADJUST BLENDING VALVE
-
Adjust blending valve during ATM tank filling to TDS levels per desired settings. Review TDS levels from digital TDS meter.
-
Adjust values plus or minus on the blend valve. Monitor consistency when set.
-
Let the tank fill completely with the set optimized water. ATM tank system status light turns from blue to green. CONNECT TO EQUIPMENT
-
Connect end of outlet tubing to equipment.
- If garden hose connection is not required –use alternate connection to ½” ID tubing (not included).
- If using garden hose fitting to ½” hose, secure with clamp.
- A Separate the hose barb adapter into three parts: threaded fitting, barbed flange, gasket. Slide band clamp onto hose first and threaded fitting second.
- B Insert barbed flange into hose.
- C Push until edge of flange is flush with hose tip.
- D Insert gasket into threaded fitting.
- E Slide band clamp to end of hose and tighten screw.
-
Open outlet valve on RO processor to allow optimized water to enter equipment.
- Water will begin to enter equipment.
- Complete final check for leaks.
- Reinstall ATM tank cover and 6″ access lid.
SYSTEM INSTALL AND FLUSHING COMPLETE
Treated water is in use at equipment.
It may take several hours to completely fill the tank and fully pressurize the system. Make sure to check for leaks when fully pressurized.
NOTE: The blended water tubing/piping and associated fittings connecting
the RO blended water outlet to the equipment being serviced should be food-
grade material that meets NSF® Standard 51, 61, or similar, with a minimum
pressure rating of 100 psi (6.9 bar, 0.69 MPa).
The RO/blended water may react with metal piping, creating a corrosive
condition in addition to imparting an objectionable taste.
Plastic pipe or reinforced beverage tubing are generally very good material
choices for RO water distribution piping.
The size of the blended water tubing/piping should be 1/2-inch (12.7 mm) O.D.
minimum.
FILTER CHANGE AND FLUSHING PROCEDURE
RECOMMENDED: Replace mineral feed cartridge every 6–12 months.
For 375 systems use 4CM cartridge. For 650 system use 7CM cartridge. RO
membranes should be replaced every 12-24 months.
Refilters should be replaced every 4-6 months when capacity is reached, or
when feed water pressure or flow becomes inadequate.
RECOMMENDED: Replace air filter on the ATM tank every 12 months.
REMOVE SYSTEM FROM INCOMING PRESSURE
NOTE: Following this process will allow water remaining in ATM Tank to
continue to supply water to equipment.
-
Turn inlet valve right to the OFF (horizontal) position.
NOTE: Feed water is shut off to filters in this “filter change” position. -
On the ATM tank, close ATM TANK INLET valve.
-
To catch water from sample port valve, place bucket beneath processor. Release system pressure, open sample port valve (pointing down).
NOTE: The ATM system requires the solenoid to be open to remove pressure. If tank water level is low or the system status light is blue, the ATM tank is filling with water and the solenoid is activated. Initiating a permeate flow test is not required. -
If system status light is green, press and hold the white button on the electronic control box for two seconds. This will open the solenoid. REMOVE FILTERS
-
Make sure incoming pressure is at 0 psi.
-
Turn filters 90 degrees to left, pull down to remove.REPLACE PREFILTER AND MINERAL ADDITION CARTRIDGES, ADD PLUG TO MEMBRANE PORT
-
Add new refilter to position 1 (insert and turn 90 degrees to right).
- Add new mineral addition cartridge to position 2 (insert and turn 90 degrees to right).
- Add RO membrane bypass plug (stored under cover) to the farthest right position (insert and turn 90 degrees to right).
FLUSH PREFILTER AND MINERAL CARTRIDGES
-
Turn reject flush valve to open position (pointing down).
-
Close the permeate sample port valve (pointing left).
-
On the TO TANK LINE – Run Tee sample line into bucket or drain. Open tee sample port. Water will flush out of this line.
-
Turn inlet valve to open position.
- Water will start to fill prefilter and mineral cartridges. Water will run from reject/sample port and tank sampling valve.
- The solenoid valve needs to remain open; a permeate flow test may be required again if the ATM system status light is green. See image 4.
-
Flush refilter and mineral addition for five minutes or until water runs clear.
RETURN EXISTING RO MEMBRANE OR REPLACE WITH NEW RO MEMBRANE (IF REQUIRED) -
Turn processor inlet valve to closed position. (horizontal).
-
The pressure gauge will reduce to 0 psi.
-
Remove membrane bypass plug (turn 90 degrees, left and pull down). Store under cover.
-
Insert RO membrane into the farthest right position (insert and turn 90 degrees to right).
-
Turn inlet valve to open position (vertical).
-
Water will start to flush through membrane. Water will run from reject and TO TANK line sample port when solenoid valve is still open.
IF REUSING EXISTING MEMBRANE, SKIP TO STEP 22
FLUSH NEW MEMBRANE
Before flushing new membrane: The ATM tank requires water level to be low indicated by a blue ATM system status light.
This requires the solenoid valve to remain open during the flush time. -
Ensure tank inlet valve is closed as in step 2 .
-
Ensure the TO TANK LINE Tee sample line is open and running to a drain as in step 10.
-
-
Put system into partial bypass to continue to supply feed water to equipment during membrane flush:
- Turn inlet valve 45 degrees.
- Turn outlet valve to the right.
NOTE: Partial bypass allows feed water to go to equipment and also allows water to flush RO membrane.
-
Continue to flush membrane for one hour with reject flush valve open.
-
After one hour close reject flush valve. Closed = pointing left.
-
Continue to flush membrane for 23 hours. NOTE: Permeate water can be flushed through thetank sampling port.
You can run additional tubing from the tank sampling port to a drain.
RETURN RO SYSTEM TO NORMAL SERVICE -
After new membrane flush, or initial flush of existing membrane (step 17) ensure reject flush valve (step 20) and all sample ports/valves are closed.
-
Ensure system inlet and outlet are returned to service positions. Inlet (pointed down), outlet (pointed up).
-
On ATM tank, turn ATM tank inlet valve to open position to allow water to enter ATM tank.
-
Adjust TDS blend per step 11-13.
Filter change and flushing complete.
Optimized water is now in use at equipment.
TDS MONITOR
This model of the EZ-RO comes preinstalled with a TDS (Total Dissolved Solids)
monitor.
This TDS monitor measures the combined TDS from the mineral feed cartridge and
blend valve going to the storage tank.
Total Dissolved Solids is the total amount of inorganic elements, including
minerals, salts or metals, dissolved in a given volume of water, other than
the pure
water molecules (H2O) and suspended solids. TDS is expressed in parts per
million (ppm).
Additional hook and loop is supplied to attach the TDS monitor to another
surface within the maximum length of wire.
SPECIFICATIONS
- TDS Range: 0-9990 ppm
- Resolution: 1 ppm (0-999); 10 ppm (1000-9990, indicated by a blinking ‘x10’ image)
- Accuracy: +/- 2%
- Cable Length: 24.5″ (including sensor)
- Power Source: 2 x 1.5V button cell batteries (size: LR44) (included)
- Battery Life: approximately one year
- Dimensions: 7.6 x 2 x 4.7
USAGE
- Press the “ON/OFF” button.
- The monitor will display the TDS level.
- The displayed TDS will be most accurate after approximately 10 seconds.
- Turn off the unit. It will automatically shut off after 10 min.
CHANGING THE BATTERIES
- Unscrew the three metal screws (not the orange plastic screw) on the rear of the unit and remove the back panel.
- Remove the batteries.
- Replace with two new LR44 batteries. Ensure the polarity is correct.
- Close the back panel and replace the screws.
RECALIBRATION
Your monitor was factory calibrated to 342 ppm (NaCl).
This level is suitable for most tap water/filtered water applications.
However, you may need to recalibrate based on your needs, as well as from
time-to-time to ensure best results.
-
Purchase a calibration solution from your dealer that is correct for your needs.
-
Disconnect the T-Fitting from its hose. Do not remove the sensor from the T!
-
Ensure the orientation of the sensor to the fitting is correct, as in the illustration.
-
Turn on the monitor and place the T-Fittings (with the sensor in it) into the calibration solution. You will get a reading.
-
If the reading on the monitor does not match the solution, adjust the reading up or down by gently turning the orange screw on the rear of the monitor clockwise or counter-clockwise.
-
The monitor should read approximately 10% below the calibration solution. The monitor is designed for flowing water and this discrepancy will compensate for that.
NOTE: If you are calibrating with a flowing solution, ignore this. -
Once the reading is correct, turn the monitor off and remove from the solution.
Your monitor is now calibrated.
CARE, MAINTENANCE
- Never touch the sensor pins, as skin oils may adversely affect the TDS measurement.
- To clean the sensor pins, clean with rubbing alcohol and let air dry.
- If you notice the readings are off from what they should be, replace the batteries or re-calibrate.
If your meter displays an ‘ERR’ message this could be for one of the following reasons:
- The TDS level is out of the range of the meter (over 9,990 ppm).
- The sensor connector has been pulled out of the monitor.
- There is something wrong with the unit. Contact Pentair customer service.
TROUBLESHOOTING
Problem | Possible Cause | Solution |
---|---|---|
No water running to equipment. | Water supply is turned | |
off. | Turn on the water. |
Water supply is blocked.
Refilter is plugged.| Clear blockage.
Change refilter.
Membrane cartridge is fouled.| Replace membrane cartridge.
Incoming water line is crimped or pinched off.| Check incoming line and verify
no crimps in line. Remove any pinch points.
Running out of optimized water| Operating pressure
reduced| Refilters need to be replaced.
Very cold feed water| Feed water temperature too low, increase water
temperature up to 80°F to increase production with tempering valve or check if
larger RO membrane or tank can be added.
Valves are in incorrect positions| Ensure the inlet valve and outlet valve on
the RO processor are open. See hang tag for normal operation. On the
atmospheric tank, ensure the inlet valve is open and the buffer tank outlet
valve is open.
Atmospheric tank not working- No power| See “depressurization pump does not
turn on” page 23.
Demand exceeds system capacity| Check RO permeate flow. Water temperatures of
48°F will reduce permeate output by 50%. Inlet pressures of 30 psi will reduce
permeate output by more than 50% compared to 60 psi inlet. Consult with
technical support if permeate flow is too low. Determine if the demand is
unusual or inconsistent, or resize system with higher capacity membrane and/or
tank.
Atmospheric tank -Low water level- Atmospheric tank system status yellow or
flashing yellow| If system status is yellow, water will need to fill to
minimum level. After water refills tank above low level sensor, the status
light will flash yellow and the depressurization pump will start after 5
minute delay.
Atmospheric tank- Depressurization pump running, but not pumping water| Pump
is air locked. Remove outlet pressure from pump by draining outlet to reprise
pump.
Reverse osmosis membrane fouled| Replace reverse osmosis membrane every 12-24
months. See “Short membrane life” page 23 for additional information.
Low feed water pressure| Install optional feed water pressure booster pump to
get pressure up to 60-80 psi. Check outlet pressure of existing booster pump
if already installed.
Tank overflowing| High level sensor and tank float shut-off failing|
Check sensor connection, verify if connected to wire harness. Replace if
needed.
Open tank cover and check float shut-off by raising float; replace if
necessary.
Poor quality optimized water| Blend valve out of adjustment|
Follow steps on page 17 to adjust blending valve.
Low TDS rejection < 75%| Inlet and outlet valve not in normal
operation| See Hang tag for normal operation. Measure reject flow rate and
compare to reject flow restrictor chart on page 13. Replace refilter,
capillary flow control and RO membrane as needed. When moving inlet and outlet
handles from bypass to service positions, you may detect a pressure imbalance
that prevents the outlet handle from reaching full final position. Correcting
this issue by turning the valve outlet or inlet handles open and closed again,
will help equalize pressure to allow inlet and outlet valves handles to fully
engage to the service position.
Blend valve out of adjustment| Follow steps on page 17 to adjust blending
valve.
Membrane failure| Measure TDS out of permeate sample port. Measure reject flow
rate. Replace refilter and RO membrane as needed. Check to see if the
capillary flow control is plugged. Replace capillary flow control as needed.
Nonblended optimized water
< 25 ppm
| Mineral feed cartridge exhausted| Replace mineral feed cartridge with 4CM
for 375 system, 7CM for 650 systems every 6–2 months.
Problem| Possible Cause| Solution
---|---|---
Short membrane life| Permeate /reject water ratio not adjusted
correctly| Measure and adjust the reject flow rate per page 13.
Poor feed water quality, presence of Hydrogen sulfide, iron, manganese, silica
or hard water| Determine feed water quality by obtaining a water quality
report from the city water supply utility or contact your Ever pure dealer for
a water test. See incoming water requirements on page 6.
High chlorine levels in feed water| Contact your Ever pure dealer for a
recommended refilter change schedule.
Refilter filtering capacity has expired| Change refilter every 6 months or as
needed.
Short refilter life| Heavy sediment loading| Change refilter
more often or add an additional 10 micron coarse refilter before system (E-10
10 inch filter EV9795-80 or E-20 20 inch filter EV9795-90).
Processor drain does not shut off| High level sensor
malfunction| If water continues to flow to the drain after the tank is full
and the system status shows a blue light (tank filling), this indicates the
high level sensor does not detect water. Check to make sure that the high
level sensor harness is connected correctly. Remove sensor and test it to see
if replacement is required.
Processor solenoid malfunction| If water continues to flow to the drain after
the tank is full and the system status shows a green light (tank full), this
indicates the RO processor solenoid valve is not closing. Disconnect the M12
connector cable from the RO processor to check if water continues to drain. If
so, solenoid is stuck in open position. Service solenoid and replacement might
be required.
TDS Monitor will not turn on| Display will not turn
on| Battery life expired: Replace batteries. Sensor module damaged: Replace
TDS unit.
Tank full of water but water will not
dispense| Tank valve closed| Open tank valve.
Pump failure| See “Depressurization Pump Does Not Turn On” below.
Bladder ruptured| If tank does not hold recharge pressure or water is coming
out of Schrader valve, replace tank.
Depressurization pump does not turn on| System
status light off (on top of control box, under atmospheric tank lid)| If
system status light is Off, ensure power cord is plugged into an outlet with
power (check circuit breaker), and that water is in the tank. If LED will not
turn On (with power and water in the tank), there may be a problem with the
control. Contact your service provider for additional help.
System status light is green or blue| Check power cable connections to pump.
Check to make sure tank outlet valve is open and RO processor valves are in
service positions. If pump continues to not run, call for service to replace
pump.
System status light flashing
yellow or solid yellow
| If Status LED is solid yellow, depressurization pump is off because of low water level. Allow processor to partially fill tank with water. Flashing yellow LED indicates depressurization pump will start after delay of five minutes and
additional water will fill the tank. Pump will activate after delay and will turn off when the outlet line pressure reaches >60 psi or tank runs low of water and LED turns yellow.
Depressurization pump brushes worn| Try bumping the depressurization pump with
your hand. If it turns on temporarily the brushes are probably worn. Replace
pump.
Depressurization pump is damaged| Call for service to replace pump.
Depressurization pump is leaking| Possible seal wear or
O-ring damage| Call for service to replace pump.
Problem| Possible Cause| Solution
---|---|---
Repressurization pump runs intermittently or roughly|
Air trapped in pump head| Unplug pump temporarily. Open valve downstream to
remove outlet pressure from pump. Plug in pump to reprime pump. When water
flow is steady, close valve downstream.
Repressurization pump motor brushes worn| Call for service to replace pump.
Bad power supply| Upon starting up the pump, the pump may struggle to start or
fail to start. At the same time the system status light will start blinking
red. Call for service to replace power supply.
Repressurization pump cycles on-off frequently| Low air
precharge in buffer tank| Empty buffer tank and precharge air pressure to 20
psi through Schrader valve.
Low water pressure at water using equipment|
Tubing between reverse osmosis system and equipment too small| Increase tubing
size between reverse osmosis and equipment to 1/2″ or larger.
Incorrect precharge in tank| For atmospheric system, precharge tank to 20 psi
when empty.
Out of adjustment pressure switch on repressurization pump| Adjust pressure
switch on repressurization pump to turn off at 60-70 psi.
Bladder ruptured| If tank does not hold precharge pressure or water is coming
out of Schrader valve, replace tank.
Objectionable water odor or taste| Storage tank requires
sanitization| Sanitize storage tank. See tank sanitization section.
Additional post filtration needed| Add additional carbon filtration on outlet
of system.
Reject water flow rate too low or decreases over
time| Drain line restricted| Check/correct any restrictions in drain line
tubing, no loops or kinks. Make sure to allow an air gap at the drain. Close
RO processor inlet valve, wait for pressure gauge to read zero, disconnect
reject line at quick connect fitting and inspect for obstruction or damage.
Replace tubing and flow control as needed.
System status flashing red
To rule out these possible causes go
through the following steps from A to D.|
A. High motor current detected: short circuit| Disconnect motor cable
connection. Open faucet downstream of tank. If ATM tank is empty, bypass water
into tank until low level sensor is covered. Unplug tank from electrical
outlet and plug back in. If error goes away, motor will need to be replaced.
Contact your service provider. If error does not go away, plug in motor cable,
and refer to “Short in solenoid or cable” in troubleshooting
B. Short in solenoid or cable| 1) Disconnect solenoid cable
connection from solenoid valve. Unplug tank from electrical outlet and plug
back in. Press and hold button on ATM controller for
2 seconds, if error goes away, processor solenoid will need to be replaced. Contact your service provider. If error does not go away, proceed to step 2.
2) Disconnect ATM solenoid cable connection from the processor M12 solenoid cable connection. Unplug tank from electrical outlet and plug back in. Press and hold button on ATM controller for 2 seconds, If error goes away, processor solenoid cable will need to be replaced. Contact your service provider. If error does not go away, refer to water level sensor issue troubleshooting.
C. Water level sensor issue| High level sensor senses water with low
level sensor not sensing water. Ensure Low tank sensor is pressed firmly up
against tank wall, Inspect low level sensor cable and connection, and/or
replace low level sensor.
Unplug and reconnect low level sensor connection. If error goes away, low
level sensor may need to be replaced.
D. Controller issue| If error does not go away, remove power cord from
outlet, power down system, and contact Pentair technical support.
Pentair hub status LED is always blue| Pentair
hub not present| The Pentair hub status feature is currently not available.
The hub status LED can be ignored.
