Reverse Osmosis In order to understand reverse osmosis, we must first define osmosis. Osmosis is the passage of a liquid through a semi-permeable membrane. A semi-permeable membrane is a membrane which allows one component of a solution to pass through it and not the others. In osmosis, there is a tendency for a liquid to go from an area of less concentration to an area of more concentration through a semi-permeable membrane. Figure 1 shows the osmotic process.

Figure 1. Osmotic process.

If sufficient pressure is applied to the concentrated solution, reverse osmosis will take place. The pressure causes a flow through the semi-permeable membrane into the dilute solution. The semi-permeable membrane acts as a barrier to most ions and many other contaminants and does not allow them to pass through into the dilute solution. When applied to water, this means that the product water has a reduced total dissolved solids content as a result of the passage of water molecules through the membrane while the mineral ions are rejected. See Figure 2.

Figure 2. Effect of pressure on reverse osmosis.

Rejection and Recovery Feed water entering the system is split into two streams, a product stream and a concentrate stream. See Figure 3.

Figure 3. Feed water product stream and concentrate stream.

During the process of reverse osmosis, some of the water has its dissolved solids content reduced by approximately 98 percent. This high quality product water is sent to service.

The rest of the feed water contains the dissolved solids removed from the product water; this concentrate water is sent to the drain.

The amount of total dissolved solids rejected by the system is expressed as a percentage. A 90 percent rejection means that 90 percent of the dissolved solids have been removed from the feed water by the system. To calculate the percent rejection, use the following equation:

Introduction 7Cat. No. 01022940

(Feed TDS - Product TDS)

(Feed TDS) x 100 = % Rejection

Where Feed TDS is the total dissolved solids content of the water going into the system, and Product TDS is the total dissolved solids content of the high quality product water. The TDS needs to be measured with a handheld meter.

For example, if the Feed TDS is 600 ppm and the Product TDS is 24 ppm, 600-24 x 100 = 96% Rejection

The amount of high quality water recovered for use as a percentage of the water fed into the reverse osmosis system is called percent recovery. Use the following equation to calculate percent recovery:

Product Water Flow Rate (PFLOW)

Feed Water Flow Rate (FFLOW) x 100 = % Recovery

NOTE! Numbers used in these examples might not reflect those of your unit.

CAUTION!

An understanding of rejection/recovery percentages and temperature compensation is essential for monitoring and evaluating the performance or condition of the reverse osmosis system.

DO NOT operate the system before becoming familiar with these concepts.

Temperature Compensation As the feed water temperature decreases so will the product water production. The rated product flow (gallons per minute, gpm) as shown for the various models on page 8 is based upon the feed water temperature equal to 77° F.

Feed Water Limits Before starting the installation, verify that the feed water meets the limits shown in Table 1 and that a water softener is used for pretreatment.

Table 1. Feed water limits.

Property Minimum Maximum Turbidity (NTU) 0.0 1.0 pH* 6 11

Chlorine (ppm) 0.0 0.1

Total Dissolved Solids (ppm) 50 2500

Temperature (°F) 33 100

Silt Density Index 0.0 5.0

Iron (ppm) 0.0 0.1

*Short term cleaning is acceptable for pH ranges between 2.0/12.0. Additional treatment is required when chloramines are present and the pH levels exceed 9.0.

NOTE! In some applications, a water softener is not required. Consult an independently operated Culligan dealer for further information on these special applications.

Membranes Before mounting the membrane housings, the membranes must be inserted into the housings.

Take care to not damage the end cap O-rings or membrane brine seal.

The membranes are shipped in a sealed package. Use extreme caution when opening the package with a sharp instrument. Any damage to the membrane can cause poor quality coming from the unit.

1. The membrane housings have directional arrows on them that indicate direction of flow.

Install the membranes in the direction of flow.

2. Remove the end caps from all vessels by removing the two Allen head screws that hold down the retaining clips.

The clips are pushed into an internal groove in the housing, so completely remove the screws so the clip can be slid out of the groove. Note placement of the caps to assure reinstallation in the same orientation.

3. Check the O-ring seals on the membrane and end plug, and the membrane brine seal for damage. If an O-ring is cut or crimped, it may cause high flow and poor quality. Replace any suspicious-looking O-rings.

4. Remove a new membrane from its plastic bag. Lightly lubricate the O-rings with a silicone-based lubricant or use a mixture of 70 percent glycerin and 30 percent water.

CAUTION!

Do not use a petroleum-based lubricant; it will damage the synthetic rubber and the membrane.

5. The brine seal on the membrane is to be installed toward the inlet side of the membrane housing.

The brine seal end should go in last.

6. Repeat for the remaining membrane housings. There may be one to four housings on each model.

NOTE! The RO elements (membranes) require a 24 hour pre-service flush.

Plumbing Installation Refer to Figure 13 through Figure 18 and the hydraulic schematic/flow diagram on page 47 for further information.

Feed Water Connections Connect tubing to the Feed water inlet. Observe the following:

1. To minimize pressure loss, the tubing size should be at least 1/2”.

2. Install an optional pressure gauge (part number D1006272) before the pre-filter.

This allows you to measure the pressure differential across the filter cartridge.

3. Install a tee, with a shutoff valve on the branch, to provide a connection for introducing cleaning solutions.

4. If necessary, install a pressure regulator (50 psi downstream max. setting) in the inlet plumbing, to assure constant pressure and to prevent harmonic vibration.

5. Install a shutoff valve in the inlet plumbing to simplify maintenance and service.

6. If the feed water can be used for a short period, install bypass plumbing around the unit.

Concentrate Water Connections

1. Direct 3/8” piping to drain from the outlet of the unit.

2. To prevent siphoning of the water in the unit to drain, raise the concentrate piping above the level of the modules and provide an anti-siphon loop.

WARNING!

An air gap must be provided between the end of the concentrate tubing and the drain to prevent back-siphoning of drain contents

Product Water Connections The product water exits the unit at the top of the module housings.

Connect the product tubing as shown in Figure 13 through Figure 18.

CAUTION!

This unit produces high quality product water. This water can be contaminated by plumbing following the unit or it can corrode the plumbing. Use only plumbing components of inert material that are compatible with the application.

The connection of the main product tubing to service plumbing will depend on how the product water will be stored.

CAUTION!

Reverse osmosis elements will fail immediately if pressurized product water is allowed to flow backward into the unit.

Pressurized Storage Tank The product water can be stored in a pressurized storage tank with the reverse osmosis unit controlled by a pressure switch. Use the same components used for direct feed (see Figure 19) with the addition of a pressure switch which needs to be wired to the control panel, refer to the pressurized storage kit manual part number 01882263 for connections. A pressurized water storage kit is available under part number D1013880 (110 V) and part number D1018976 (220 V). Connect the product tubing to a pressurized storage tank such as P/N 01005095 (2 gallon), P/N 01004776 (3-gallon), or P/N 01004765 (9-gallon).

Non-Pressurized Product Water Storage Tank Connect the product tubing to a bulkhead fitting at the top of the storage tank.

Depending on the type of application, a level control may be required to turn the unit off when the storage tank is full.

Install the level control according to the instructions provided with the Level Control. Refer to the wiring section in this manual for electrical connections.

NOTE! If a repressurization pump is used, an additional level control is recommended to prevent the pump from running dry if the storage tank is empty.

To maintain high water quality, a hydrophilic air vent filter, vacuum breaker, pop-off valve, ultraviolet lamp, and pressure relief valve may be required.

Direct Feed If the product water is to be used directly, without storage, a few precautions are necessary to prevent damage to the elements. Install a pressure gauge, pressure switch, and a normally-open (“dump”) solenoid in the product water line as shown in Figure 19, or use pressurized storage kit (P/N D1013880 (110 V) or P/N D1018976 (220 V).

The pressure gauge will allow the operator to monitor the product water pressure. The switch, which should be set to open at 40 psig, will prevent the product water pressure from exceeding 40 psi. The dump solenoid will relieve all pressure when the unit is off.

Figure 19. Direct feed connection.

Wire the direct feed/pressurized storage solenoid valve in parallel with the motor.

Valve SV4 closes when the RO pump runs; SV4 opens when the pump stops, allowing all membrane back pressure to be relieved.

NOTE! Product back pressure will decrease the net pressure pushing water through the reverse osmosis elements; therefore, the flow of product water will decrease.

Electrical Installation

WARNING!

The system must be grounded. Do not remove grounding prong!

An improperly grounded unit could cause injury from electrical shock!

CAUTION!

Observe the cautions listed below before the electrical installation of the controller.

Failure to do so might cause permanent damage to the RO controller.

CAUTION!

Before performing any electrical wiring refer to the electrical schematics.

WARNING!

Disconnect ALL power supplies when performing any electrical wiring.

A 120 VAC/60 Hz/1 phase grounded electrical receptacle with 15 Amp fuse protection is required for use with the six-foot, three-wire power cord.

Pre-Installation Recommendations

• Follow the local electrical code requirements.

• Be sure electrical power is off and disconnected at the source before completing any wiring/cabling connections.

• Maintain a distance of at least 10 feet between the controller and any electrical distribution panels, raceways carrying 300 volts or more.

• Use the cabling provided. Failure to do so may affect performance of the controller adversely.

High Voltage Connections To open the control panel, unscrew the door screws in the counter clock-wise direction and swing the door open.

Timers/Jumper Switches

Timers/Jumper Switches In order to change the timing for the startup, pump motor startup, and flush mode, follow these instructions:

A This is the delay time for startup of the unit without using the red button and has two options, 60 minutes or 15 minutes. Without the jumper the delay will set at 60 minutes. If the 2 holes opposite each other are jumpered, it will change that delay to 15 minutes.

B This is the delay time for startup of the pump motor after pushing the button. Without the jumper, the inlet solenoid comes on and the pump will start in 60 seconds. If the 2 holes opposite each other are jumpered, it will change that delay to 15 minutes.

C This is for the flush mode. If the RO runs for 2 hours straight without shutting off, the unit goes in to a flush mode for 60 seconds. If the 2 holes opposite each other are jumpered, it will go into flush mode every hour.

Dump Solenoid Connection For direct feed applications, the dump solenoid is wired to the 120 Volt motor cord contacts L1 and L2. When the motor is running the dump solenoid valve is energized and closes. When the unit shuts down, the dump solenoid valve opens to drain.

Dry Contact Connections The dry contact terminal strip is located on the bottom right of the circuit board (see Figure 21).

Do not apply any voltage to these terminals. Use dry contacts only.

Start-Up 29Cat. No. 01022940

Start-Up

1. Open the feed water supply valve.

2. Direct the product water tubing to drain.

3. Open the recirculation valves HCV-1 and HCV-2 fully counterclockwise.

4. Turn the power switch ON. You must press the RUN NOW button (see Figure 21 on page 25) for the unit to start up without delay.

NOTE! If the inlet pressure falls below 20 psi during operation, a booster pump will be necessary.

CAUTION!

If the pump chatters loudly, it is starving for water (cavitating). Turn the unit OFF immediately to prevent pump damage. Correct the low pressure condition before proceeding.

5. Check for leaks at all tube fittings and threaded joints.

6. Slowly close the waste valve until the product and waste flows are approximately equal.

7. Slowly close the recirculation valve and adjust the waste valve to match the membrane feed pressure and system recovery flow rates (see “Specifications” on page 8).

NOTE! The RO elements (membranes) require a 24 hour pre-service flush.

CAUTION!

As the concentrate flow is reduced, the system pressure will increase.

Open the system pressure control valve as required to prevent the system pressure from exceeding 150 psi (1034 kPa). Excessive pressure will damage the pump and may cause property damage.

NOTE! Depending on the feed water quality, it may be possible to operate the unit with a lower concentrate flow rate, which would decrease operating costs. Refer to the printout from the Culligan® CAAP® (Computer Aided Application Program) software, which indicates maximum allowable recovery. If a printout is not available, contact the Culligan dealer.

CAUTION!

DO NOT exceed 150 psi (1034 kPA) or the membranes may be damaged.

The fittings and tubing may also fail and may cause property damage.

NOTE! By adjusting the feed pressure as low as possible to meet the application requirement, the service life of the pump and RO elements will be optimized. The system should run continuously, rather than go through frequent start/stop cycles. Do not exceed specified product flow rate!

30 Culligan® M1 RO 30 Cat. No. 01022940

8. Once all the desired flows are set, allow the system to run for approximately 30 minutes, and then record the following measurements using the units gauges (U) and your instruments (I):

a. Feed Water Temperature, °F (I)

b. Feed Water SDI (I)

c. Feed TDS, ppm (I)

d. Inlet Pressure, psig (I)

e. System (pump outlet) pressure, psig (U)

f. Waste Flow, gpm (U)

g. Product Pressure, psig (I)

h. Product flow, gpm (U) x TCF1 =

i. Feed Flow (=Waste Flow + Product Flow)

j. % Recovery (see page 6)

k. % Rejection (see page 6)

1TCF = Temperature Correction Factor. Refer to Table 2 on page 33 for this value.

9. Turn the power OFF. Connect the product tubing to the service plumbing.

10. Apply power to the unit, and then press the RUN NOW button.

11. Test the operation of the inlet pressure switch by closing the inlet water supply valve. The unit should shut down the pump and inlet valve immediately. The POWER and READY lights should remain on.

CAUTION!

If the unit does not automatically shut down, turn the unit power switch OFF immediately to prevent pump damage. Disconnect electrical power source, then check the wiring and replace the switch, if necessary.

12. Open the inlet water supply valve, apply power, and press the RUN NOW button.

The unit should begin producing RO water.

13. If installed, test the storage tank level control shutdown and the pretreatment lockout function.

Start-Up 31Cat. No. 01022940

Controller Behavior when Power First Applied

press the RUN NOW button on the bottom of the controller. The controller opens the RO inlet solenoid valve.

NOTE! The RUN NOW button will not work if any of the following five events are occurring:

• Tank Full switch is OPEN (open status indicates the water level in the tank has reached the TANK FULL state)

• Pretreatment lockout switch is OPEN (open status indicates a device upstream of the RO is requesting that the RO not be in service)

4. Wait for an additional one-minute period. The INLET VALVE OPEN LED is lighted. During this period, feed water under line pressure enters the RO, passes through the pump, flushes through the upstream (feed water side) of the membranes, and then passes to the drain.

5. Because the line pressure is expected to be fairly low (lower than 100 psi) very little permeate water is created during this flush time. Instead, any high-TDS water on the membrane feed side is flushed to drain.

6. When the one-minute period has elapsed, the controller checks to see if there is sufficient incoming water pressure to operate the RO.

a. If there IS pressure, the controller turns on the main pump and the RO produces permeate water.

The PUMP ON LED is lighted.

this delay, flush, and attempt to start cycle indefinitely up to 24 restart attempts per day.

7. Once the controller successfully enters the make-water mode, the first four LEDs will be lighted: red, green, green, and green. The pump will continue to operate and produce RO water until one of the following five events occurs:

• Tank Full switch is OPEN

• Pretreatment lockout switch is OPEN

• Loss of electrical power

• Loss of inlet pressure

• Two-hour continuous make-water timer expiration When any of these five events occurs the system immediately ceases making RO water.

The pump will turn off, and the inlet solenoid will close.

8. If the unit has stopped for either tank full or pretreatment lockout conditions, it will remain off until these conditions no longer exist, and the LED indicating POWER status will be lighted. Once the tank is full or the pretreatment lockout condition ends, the LED indicating READY is lighted and the unit will then reopen the inlet solenoid. Wait one minute, and then start the pump to return to the make-water condition.

9. If the unit has stopped because of either an electrical power loss or loss of inlet pressure, the system will follow the behavior described in step 1.

10. If the unit stops because it has been in a continuous make-water operation for the previous two hours, the pump will remain off for one minute. During this time, the inlet solenoid valve will remain open, and the system will perform a line-pressure front-side membrane flush to drain. The first three LEDs will be lighted.

At the end of the minute, the system will return to make-water mode. The fourth LED will now be lighted again.

If the system includes an optional TDS probe, and the measured product TDS rises above the customer-set threshold for at least three minutes, then the product quality is too low. The system will shut off the pump (to stop making water) and close the inlet valve. The LEDs for POWER, READY, and HIGH TDS will be lighted.

32 Culligan® M1 RO 32 Cat. No. 01022940

Setting the TDS Threshold (If your system is equipped with the optional TDS Probe) There is a bank of DIP switches located along the left side of the CP Plus controller. See Figure 21 on page 25. Each switch can be set to either ON or OFF. The system continuously monitors the product water TDS while it is making RO water. If the product TDS falls below the specified threshold for more than three minutes, the system will stop making RO water. The threshold specifications is selected as shown below:

Dip Switch

Dip Switch

Dip Switch

Dip Switch

Dip Switch

Product Water TDS Approximate Threshold

ON OFF OFF OFF OFF 25 ppm max TDS

OFF ON OFF OFF OFF 50 ppm max TDS

OFF OFF ON OFF OFF 75 ppm max TDS

OFF OFF OFF ON OFF 100 ppm max TDS

OFF OFF OFF OFF ON 125 ppm max TDS

NOTE! DIP switch settings are not designed to perform accurately when multiple DIP switches are in the ON position. Setting more than one switch to the ON position will result in a reading less than either switch setting.

Normal Operation During normal operation, the system usually will start up and shut down based on signals from a level control or pressure switch. Adjust the feed pressure as required (no higher than 150 psig) to maintain a constant product flow. Record the performance data regularly and compare it to the performance on initial start up. If any changes are noticed, the product flow should be normalized to determine if cleaning is required (see “Product Flow Calculations” below).

Product Flow Calculations The product flow rate depends primarily on feed water pressure, product water pressure, and temperature. All Series E and M units have specified nominal flow rates based on approximately 105 psig net pressure and 77°F temperature. However, in most applications the temperature and pressure are lower, so the product flow rate is lower than the nominal flow rate. The actual flow rate must be converted to flow under standard conditions, then compared to the initial performance (also converted to standard conditions) to determine whether the system is still working properly.

To convert the data to standard conditions,

1. Measure the product flow. Example: 1000 ml/min

2. Measure the feed pressure. Example: 120 psig

3. Measure the product pressure. Example: 5 psig

4. Subtract the product pressure from the feed pressure. Example: 115 psig

5. Divide the product flow by the result from step 4. Example: 1000 ÷ 115 = 8.69 ml/min/psi

6. Multiply the result from step 5 by 105. Example: 8.69 x 105 = 913 ml/min

7. Measure the temperature of the feed water, then determine the temperature correction factor from Table 2.

Example: At a temperature of 55°F , the factor is 1.54.

Start-Up 33Cat. No. 01022940

Table 2. Temperature Correction Factors

Temp. °F Temp. °C Correction Factor Temp. °F Temp. °C Correction Factor

40 4.4 2.12 75 24 1.04

60 16 1.39 95 35 0.72

65 18 1.26 100 38 0.66

70 21 1.14

8. Multiply the result of step 6 by the temperature correction factor. Example: 913 ml/min x 1.54 = 1406 ml/min.

NOTE! To convert ml/min to gallons per day, multiply by 0.38. For example, 1406 ml/min x 0.38 = 534 gpd.

9. Compare the current standardized flow to the initial standardized flow.

If the flow has decreased by 15% or more, it is time to clean the elements.

Example: If the initial standardized flow was 570 gpd, and the current standardized flow is 470 gpd, the flow has decreased by 100 gpd, or 18% (100/570) = 0.18. The elements should be cleaned.

10. If the problem cannot be corrected with the troubleshooting guide and assistance is required, please have the following information available when calling the Culligan dealer:

• Product flow rate

• Concentrate flow rate

• Feed pressure

• Product water quality

• Feed water quality

• Feed water temperature

• Prefilter outlet (and inlet if the optional prefilter inlet gauge was installed)

• Product pressure

Pretreatment Lockout The controller allows an external contact closure to cause the RO to go into a “pre-treat lockout” condition. This signal is Normally Closed. When OPEN it indicates that the system should STOP because a piece of pretreatment equipment is in a regeneration state.

When this event occurs, the system immediately stops making RO water and the pump will turn off and close the inlet solenoid. It will remain off until this condition no-longer exists and then it will re-open the inlet solenoid, wait one minute and then start the pump to return to the “make water” condition.

Timeclock controlled softeners, such as the Hi-Flo® 3, do not offer pretreatment lockout. If these units are used for pretreatment, they should be duplexed, or regenerated by a timeclock so that regeneration can occur when the RO unit is not in operation.

34 Culligan® M1 RO 34 Cat. No. 01022940

Flush Modes Line Pressure Front Side Flush Prior to Startup When main power is first applied to the CP Plus controller, the controller will first wait for a one-hour delay and will then open the RO inlet solenoid valve and waits for an additional period of one minute. During this one minute, feed water under line pressure enters the RO, passes thru the pump and flushes through the upstream (feed water side) of the membranes and then passes to drain. When the one-minute time is elapsed, the controller checks to see if there is sufficient incoming water pressure to operate the RO. If there IS pressure, the controller turns on the main pump and the RO begins to produce permeate water. If there IS NOT sufficient pressure, the entire process starts over beginning with the one-hour delay.

Line Pressure Front Side Flush Every Two Hours of Continuous Make Water The unit will stop when it has been in a continuous make-water operation for two hours. The pump will remain off for one minute. During this time, the inlet solenoid valve will remain open and the system will perform a line-pressure front-side membrane flush to drain. At the end of the one minute, the system will return to the “make-water” mode.

Level Control/Float Switch The RO controller accepts a dry contact signal that causes the RO to turn off when the water level inside an atmospheric storage tank reaches a high-level float switch. A normally closed (NC) high-level float switch is required.

The RO is in the RUN state when the dry contact input is closed. When the water in the tank reaches the high-level float switch, the switch should open. When the switch opens, the controller will turn off the RO.

Figure 25. RO level control switch.

Connect Level

Control Here

A NORMALLY CLOSED Level

Switch is required. The switch is closed when the tank water level is below the switch.

STORAGE TANK

Connect the level control (or pressure switch) to the TANK FULL terminals (see Figure 25). These terminals are intended for dry-contact wiring using 18-24ga wire. Remove the installed jumper wire when making this connection.

When this event occurs, the system immediately stops making RO water and the pump will turn off and close the inlet solenoid. It will remain off until this condition no-longer exists and then it will re-open the inlet solenoid, wait one minute and then start the pump to return to the “make water” condition.
