GBE RO Controller (GROC) Features

System Computes Normalized Flow

The system computes normalized flow and can be set to trigger an alarm if the normalized flow drops below a specified
limit.

Power Up Mode

The system can be configured to either go to standby mode or to automatically return to making RO water in the event of
power loss and restoration.

Storage Tank and Pressure Logic

The system has the ability to monitor high and low level switches in an atmospheric storage tank and a pressure switch in
a pressurized storage tank to automatically put the system into standby mode when the tank is full.

Pretreatment Lockout

Allows for single softener or filter pretreatment that can be set to go into regeneration or backwash cycle at low water use
periods and have the RO in standby until cycle is completed. RO product water tank would need to be sized correctly
based on flow demand if continuous RO product water is required.

GBE Historical Data

The GBE RO Controller stores basic performance data over the lifetime of the membranes as an aid to optimizing RO
performance and determining when the membranes need to be cleaned or replaced.

Flush Options

The system offers five different membrane flush modes to improve performance and extend membrane life.

2 Culligan® Series M2 Reverse Osmosis

2 Cat. No. 01023095

Target TDS

The RO system keeps track of the average product water TDS whenever the RO system is operating, mixing lower quality
water with product water to meet the average product water TDS.

Communications via Modem

An optional modem and monitoring service can be used to remotely monitor the RO performance over time. This service
can also be used to alert the customer and the Culligan dealer in the event that an alarm or error condition occurs.

Wireless Remote Communication

An optional wireless remote can display the current operational status and performance statistics up to 200 feet from the
G1 RO system.

PLC Outputs Available

The GBE Controller collects data once per minute and then streams the data to a customer-owned PLC for data collection
or monitoring. Customer would have to write code to take text information and convert the data for their data collection
system. For more information, see Culligan P/N 01021512 Advanced Communication Manual.

This data, once converted from a text stream, can easily be imported to an excel spreadsheet and the data logged can
then be graphed and trended.

Multi-Unit RO

The GBE RO controller supports two multi-unit modes: Two Pass and Duplex-Alternating.

When in two-pass or duplex-alternating mode, the system is configured to support two GBE RO controllers that are con­nected together using the communication cable (P/N 01016327). One of these boards is set as the master, controlling the
operations of the other unit, also known as the slave. The slave unit performs as a sensing device.

• When in Two-Pass RO mode, the primary unit, identified as the master, issues commands to control the secondary
unit, identified as the slave.

• The GBE RO controller controller is capable of coordinating the alternating operation of two RO units plumbed in
parallel. This operation mode is designed for situations where RO redundancy is desired.

Plumbing Installation

Refer to the appropriate hydraulic schematic/flow diagram on page 71 for further information.

Feed Water Connections

Connect pipe or tubing to the Feed water inlet. Observe the following:

1. To minimize pressure loss, the pipe or tubing size should be at least 3/4”.

2. Install optional pressure gauges (quantity 2 of P/N D1006272) before and after the pre-filter to measure the
pressure differential across the filter cartridge.

3. Install a tee, with an upstream shutoff valve on the branch, before the feed flow meter to provide a connection
for introducing cleaning solutions.

4. If necessary, install a pressure regulator (100 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 1/2" tubing to drain from the outlet of the unit.

2. To prevent siphoning of the water in the unit to drain, raise the concentrate plumbing 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 on the pump side of the unit in either 1/2” piping or tubing. Connect the product plumbing to the
fitting on the flow meter.

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 plumbing to service plumbing will depend on how the product water will be stored.

CAUTION! Reverse osmosis elements will fail immediately if 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 4) with the addition of a pressure switch which needs
to be wired to the control panel (see page 72 for RO standard wiring). A pressurized water storage kit is available under
part number D1018976.

10 Culligan® Series M2 Reverse Osmosis

10 Cat. No. 01023095

Non-Pressurized Product Water Storage Tank

*Use of Pressurized Storage Tank requires use of Pressurized Storage Kit D1018976.

Connect the product tubing to a bulkhead fitting at the top of the storage tank.

CAUTION! The highest point of the tubing should not be higher than four feet above the top of

the reverse osmosis modules, or the elements may be damaged.

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 control. Refer to the wiring section in this manual for
electrical connections.

NOTICE 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 relief valve, and a normally-open (“dump”) solenoid in the product water line
as shown in Figure 4. The pressure gauge will allow the operator to monitor the product water pressure. The relief valve,
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.

(D1018976)

Figure 4. Direcfeed connection.

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

NOTICE Install a check valve after these valves in case the service line remains under pressure. Product

back pressure will decrease the net pressure pushing water through the reverse osmosis ele­ments. Therefore, the flow of product water will decrease.

GROC Programming

Program Data Input

There are a few items to note that can make programming the Culligan® Global Reverse Osmosis Controller (GROC)
easier:

Slew Rates This term refers to the speed at which the display moves through the input of material. For ex-

ample, holding down the up arrow key for (5) seconds when inputting minutes for Time of Day
will cause the minutes to pass in (10) minute blocks of time. Press the up arrow or down arrow
keys for shorter periods (less than 5 seconds) will slow the rate. To move through the program­ming slowly, do not hold down the up arrow or the down arrow keys.

Beeper A beeper is available to assist the user by providing an audible tone (about 70 decibels) to signi-

fy valid (one beep) and invalid (three beeps) key presses. The beeper can be deactivated in the
programming mode. (If error occurs, beep will still sound even if set to “No” programming.)

Programming
Mode Timeout

Program Input
Acceptance

NOTE The following programming section is used for the G1, M2, G2 & G3 RO systems. The controller used

on the G1 & M2 RO units have the same programming but the controller has fewer features. Unless
otherwise specified, the programming is applicable to all units. Features not available on the G1 and
M2 are noted with a double-cross symbol (‡).

If there is no keypad activity for a one (1) minute period while in the programming mode, the
controller will exit the programming mode and return to the main display. Any setting that was
changed prior to the control timing out will revert to the original value. Pressing the CHECK
MARK button saves the setting.

For programming information to be accepted, the check mark key must be depressed prior to

programming mode timeout.

Flush Modes

The GBE RO controller can be programmed to operate up to six different flush modes. Multiple flush modes can be speci­fied and operating at any one time. If any one or more flush modes are calling for flushing to happen at a certain time, the
flush will take place. Some flush modes require additional plumbing and components such as solenoid valves.

Startup Flush

In this mode the fast flush solenoid (SV-2, Optional) opens for a specified number of minutes each time that the pump
turns on.

Standby Flush

In this mode any time that the system state is in STANDBY, the inlet AND fast flush solenoids open for a specified number of
minutes every specified number of hours. This is a line-pressure-level flush (ie the pump does NOT turn on during this flush).

In this mode, any time that the system state is in RUNNING, the fast flush solenoid (SV-2, Optional) will open for a speci­fied number of minutes every specified number of hours. Note that the pump is ON during this flush.

Flow Trigger Flush

In this mode, any time that the system state is in RUNNING, the fast flush solenoid (SV-2, Optional) will open for a speci­fied number of minutes every specified number of PRODUCT RO water generated. Note that the pump is ON during this
flush.

Quality Flush

If this mode is enabled, the product diversion solenoid (SV-3, NOT INCLUDED) is opened as soon as the pump turns on
when the RO system is RUNNING. This solenoid will remain open until the measured product TDS drops below the speci­fied quality flush TDS setpoint or until the quality flush time period expires. If the TDS does not drop below the setpoint
during this period, the unit will switch to OFFLINE and the “product TDS High” error will be thrown. The Quality Flush sole­noid valve is wired to the AUX board on the GBE RO controller at terminal AUX4. The solenoid valve must be 24 VAC.

Figure 9. RO quality flush.

At startup, SV1 opens, and then the pump turns on. SV3 opens while the system monitors the product TDS level. The
user programs the maximum allowable product TDS and the number of minutes allowed following startup to reach the al­lowable TDS level. Usually at startup, the TDS level starts high and then drops. If the level drops below the allowable level
within the allowed time, then SV3 will close, and the unit is now in service. If the allowable TDS level cannot be reached,
the unit will shut down and generate an error message.

Permeate Flush

If this mode is enabled, the permeate flush solenoid (SV-3, NOT INCLUDED) is opened as soon as the
pump turns off. This solenoid will remain open until the permeate flush time period expires and permits wa­ter from an optional permeate storage tank to flush the membranes. The Permeate Flush solenoid valve is
wired to the AUX board on the GBE RO controller at terminal AUX4 (G1). The solenoid valve must be 24 Volt.

At shutdown, the pump turns off and SV1 closes. Then fast flush solenoid valve SV2 and permeate valve SV3 open for a
programmed number of minutes. During this time, RO produt water stored either in an elevated atmospheric tank or in a
pressurized storage tank floods through the pump and the feed side of the membrane, and then SV2 and SV3 close. This
process provides RO-quality water during shutdown on both sides of the membrane to keep the membrane clean. This
process also ensures that the RO will provide high quality product water the next time the pump is turned on.

Any time that a Flush is actually taking place while the system state is RUNNING, the system will ignore the following er­ror limits: delivered product TDS high, %recovery low, %recovery high, %reject low, membrane pressure drop, pump feed
pressure low. Once the flush ends, the error checking will resume. If the inlet pressure switch reports LOW pressure for
at least XX (XX is programmable at 1-30 seconds, at the main menu/setup/accessories/switch inputs menu) continuous
seconds, even if this is during or even partially during a flush time, the system will still recognize this instance as an error

Modem

NOTE The modem can be installed into either the back of the RO controller or the back of the remote control

board. The functionality of the modem is the same in either installation.

NOTE Use of the modem kit requires a one-year subscription to either a Level 1 or Level 2 Telecom package.

Self-service registration is available at www.myculligan.com.

1. Before installing the modem into the back of the RO Controller board or the back of the remote, the RO
Controller circuit board or the remote must first be powered off.

2. When handling all circuit boards, take care to only touch the edges of the circuit boards—not the metal pins.
The electronics on all circuit boards can be damaged by static electricity.

3. Make sure all of the pins at all four connectors are aligned between the modem board and the main controller
board. Make sure that the modem board is fully seated into all four sockets.

4. When all connections have been made restore power.

5. Connect the modem to the telephone line by plugging a standard RJ-11 phone extension cord into the modem

board.

NOTE The GBE RO Controller is designed to plug into an analog telephone line (standard residential phone

line). This includes phone lines connected to most residential VoIP (voice over Internet) phone sys­tems and to residential DSL phone systems. If you are connecting the RO to a DSL phone system,
follow the DSL provider recommended method to connect standard phones to the DSL service. Many
systems recommend or require the use of DSL line filters between the phone jack and the device.

NOTE Try to place the RO Controller or Remote Display near a telephone jack. A splitter might be needed if

the jack is already in use.

Installing the Modem on the GBE RO Controller Board

Open the controller cover and locate the modem connection on the back of the board (see Figure 13). Insert line modem
board (part number 01020747) into the socket on the back of the board. Make sure that all of the pins in all four connec­tors are aligned and make sure the modem is fully seated into all of the sockets.

Test Modem

This menu attempts to send a test message. The screen indicates whether or not this process is successful. Sending a
test message will also update the time and date on the Smart Controller to the correct time. If the modem is installed on
the main controller (as opposed to installed in the remote control) then this testing process will also check to see if there is
an updated version of firmware available on the Culligan servers.

After conducting a phone line test, it is important to verify that the new time and date settings on the controller are correct.
If the new time setting has the incorrect value for the hours it is likely that the time zone setting on the control is incorrect.
The time zone setting found under the Main Menu / Setup / Accessories / Modem screen is displayed in the format of

Terms:

“PS Sw Delay”: This delay applies when the RO is in “RUNNING” mode (pump is actually ON). It determines how long

the pump will continue to run after a loss of pressure at the dry-contact pressure switch input

“SV1 Delay”: This delay applies when the RO is in “STARTING” mode (pump is actually OFF). It determines how long
the system should stay in “starting mode” before checking the pressure switch status and deciding whether or not to start
the pump.

“Auto-restart”: In the event of a low pressure shutdown, an auto-restart attempt should be made. Basically, the system
goes into “starting” mode again. There can be a maximum of 5 restart attempts. After the 5th successful restart, the next
low pressure shutdown should put the system into OFFLINE mode with error code “problem found”.

NOTE This five-time counter on the number of restarts allowed resets to zero every night at midnight and

The pressure switch is prewired at the factory to the GBE RO controller AUX board POSITION (J1) pins utilizing pins 2
and 4. The switch is factory set to 18 psi. The pressure can be adjusted from 6 psi to 30 psi by turning the knurled ring on
the body of switch clockwise to increase the pressure and counter-clockwise to decrease. One revolution is approximately

6.5 psi.

Multiple Unit ROs

The GBE RO controller supports two multi-unit modes: Two Pass and Alternating.

When in two-pass or alternating mode, the system is configured to support two GBE RO controllers that are connected to­gether using the communication cable (P/N 01016327). See Figure 22. One of these boards is set as the master, control­ling the operations of the other unit, also known as the slave. The slave unit performs as a sensing device.

Two-Pass RO Start Up Sequence

When configured for two-pass RO, the master unit runs a start up sequence described as follows:

• The SV1 on the GBE master opens

• The system waits for the amount of time set on the master as “SV1 Delay”

• If the pressure-switch-1 shows that pressure is present, then the GBE master turns on the pump for the first unit.

• The system waits for the amount of seconds set on the master as the “PASS 2 DELAY”.

• If the pressure-switch-2 shows that pressure is present at pressure-switch-2 then the master sends an operation

command to the slave unit that turns on the second pass pump.

The master will turn off the slave’s motor output any time it detects that one of the inlet pressure switches is off for more
than the specified “PS SW DELAY”. After the slave unit pump turns off, the master will wait three (3) seconds and then
turn off the master pump. The units follow the same procedure if operating conditions trigger the PTLO or the Tank Full
switches.

Duplex-Alternating RO Mode

The GBE RO controller controller is capable of coordinating the alternating operation of two RO units plumbed in paral­lel. This operation mode is designed for situations where RO redundancy is desired. As long as both RO units remain
functional, the controllers will direct one of the units, called “Unit A,” to be in the “ready-to-run” mode for a one hour block
of time beginning at the top of the hour. During that one hour block, Unit A will produce RO water as long as the storage
tank is NOT full and as long as there is no pre-treatment-lockout condition in effect. During this first hour, Unit B will be in
standby mode. At the beginning of the next hour, control switches to Unit B and Unit A will switch to Standby. During that
second hour, Unit B will produce RO water as long as the storage tank is NOT full, and as long as there is no pre-treat­ment-lockout condition in effect. The units will continue to switch over control at the top of each hour indefinitely.

For example, the master RO pumps on even hours (12:00 to 1:00, 2:00 to 3:00, 4:00 to 5:00, etc.), and the slave RO
pumps on odd hours (1:00 to 2:00, 3:00 to 4:00, 5:00 to 6:00, etc.).

If at any time while in duplex-alternating mode either Unit A or Unit B stops functioning, or enters an “error state” (for ex­ample if the product TDS exceeds the maximum allowable product TDS level) then the other unit will take over operation
and will continue to operate as a single stand-alone mode until an operator clears the error on the first unit.

If at any time while in duplex-alternating mode the two units lose communication with each other (for example if the com­munication cable is cut or becomes unplugged), then both units will switch into single stand-alone mode until communica­tions are re-established and an operator instructs the units to return to duplex alternating mode using the GROC menu
screens.

In Alternating-Mode, each RO unit has its own GROC controller. A standard communication cable (P/N 01016327) is
used to connect the two GROC controllers together as shown in Figure 23 and the units are plumbed as shown in Figure

24. It is necessary that each RO unit have its own independent storage tank level (or pressure) switch and that, if a

pre-treatment lockout system is to be used, that each RO have its own independent dry contact closure signal from the
pre-treatment system wired to the individual GROC controllers.

When either unit is the “running” unit, it operates as a single unit.

SV3 (Solenoid Valve) Mode/TDS Target

Solenoid valve SV3 is physically connected to the mini-aux board AUX4. When connected to AUX4, the TDS probe is set
up as PRODUCT.

NOTE Unlike SV1 and SV2, which operate at line voltage (220VAC for M2), SV3 must be a 24VAC solenoid

valve such as P/N 01021310.

SV3 has three possible modes of operation: quality flush, permeate flush, and TDS target.

Quality Flush

Solenoid valve SV3 is open whenever the RO system is in Quality Flush mode. This is the default SV3 mode.

Permeate Flush

Solenoid valve SV3 is open whenever the RO system is in Permeate Flush mode.

TDS Target

Target TDS: The RO system keeps track of the average product water TDS whenever the RO system is operating, mixing
lower quality water with product water to meet the average product water TDS. The average TDS measurements of the
RO product water are taken once per second, over an interval specified by the “TDS Target Time.” The controller opens
and closes valve SV3 every few seconds in order to produce product water with a TDS level near the programmed value.

Initial Startup

1. Open the feed water supply valve.

2. Direct the product water tubing to drain.

3. Open the recirculation valve (HCV-1) fully counterclockwise, then close two turns.

4. Connect the system to the power supply. Turn the power switch to the ON position.

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. Set the inlet pressure regulator (installed ahead of the Pre-filter) to 10 psig (69 kPa) below the minimum read­ing shown on the inlet pressure gauge, but no lower than 20 psig. This will allow for pressure variations in the
feed water.

7. Slowly close the recirculation valve until the desired (normalized) product flow rate is attained. Check again for
leaks.

8. Allow the unit to run so that the shipping solution (sodium bisulfite and glycerin) is flushed from the system. Test
the concentrate water for sulfite; continue flushing until no sulfite is detected.

CAUTION! As the concentrate flow is reduced, the system pressure will increase. Open the sys-

tem pressure control valve as required to prevent the system pressure from exceeding
150 psi (1553 kPa). Excessive pressure will damage the system.

NOTICE Depending on the feed water quality, it may be possible to operate the unit with a lower concen-

trate 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.

9. Measure the product flow. Adjust the feed pressure with the system pressure control valve until the product
flow is approximately 10% higher than the flow required for the application.

CAUTION! DO NOT exceed 150 psi (1553 kPA) or the pump may be damaged. The fittings and tub-

ing may also fail and may cause property damage.

NOTICE 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!

Cat. No. 01023095

10. 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), GROC information screens (G), and your instruments (I):

TCF = Temperature Correction Factor. Refer to Table 6 on page 57 for this value.

NOTICE The Global RO Controller has a feature which records historical data. The intial startup data is kept

in the controllers memory. It is still a good idea to record the values on a separate sheet of paper
and keep the data near the unit in case of electrical problems.

11. Turn the power switch OFF. Connect the product tubing to the service plumbing.

12. Test the operation of the pressure switch by closing the inlet water supply valve. The unit should shut off imme­diately, and the Low Pressure light should turn on.

CAUTION! If the unit does not shut off, turn the unit OFF immediately to prevent pump damage.

Disconnect electrical power source, then check the wiring and replace the switch, if
necessary.

13. Open the inlet water supply valve. The unit should restart and the light should go out.

14. If connected, test the storage tank level control shutdown and the pretreatment lockout function.

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 on the next page).

56 Culligan® Series M2 Reverse Osmosis

56 Cat. No. 01023095

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 100 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 6.

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

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

40 4.4 2.12 75 24 1.04
45 6.7 1.90 80 27 0.95

55 13 1.54 90 32 0.79
60 16 1.39 95 35 0.72
65 18 1.26 100 38 0.66

70 21 1.14

Table 6. Temperature Correction Factors

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

NOTICE To convert ml/min to gallons per day, multiply by 0.38. For example, 1099 ml/min x 0.38 = 417 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.

Calibration

Calibrating the Flow Meters

The flow meter(s) on the RO systems are calibrated by means of a K-Factor. This value is set at the factory and should
not need to be changed, even if the flow sensor is replaced.

Should it become necessary to recalibrate or reenter the K-Factor, you can use one of the two methods below. An ex­ample of this would be when replacing the circuit board.

Method A Method B

This method involves resetting the K-Factor to the factory
setting. Every unit shipped has a data sheet in the control­ler which lists the factory settings for that unit. This sheet
will list the K-Factor setting(s) for the unit. Simply reenter
the value(s).

If the data sheet is not available, contact Culligan and pro­vide the unit serial number. The values will be looked up.

If method A is not possible, then the meter can be calibrat­ed with an external calibrated flow meter or a bucket and
stopwatch. If Method B becomes absolutely necessary,
please consult a Technical Service Specialist at Culligan in
Rosemont.

Calibrating the TDS Probe

The probes can be easily field calibrated using a calibrated handheld TDS meter. Disconnect the probe from the RO
plumbing and submerge it into a solution of known TDS. Enter the ACTUAL TDS value at main menu / setup / accesso­ries/ TDS.

Prefilter Cartridge Replacement

The prefilter cartridges should be changed when the pressure drop across the prefilter increases by 15 psi (103 kPa).
Refer to the diagram in the installation section.

CAUTION! The pressure after the prefilter should not be less than 15 psi (103 kPa), or the pump

might be damaged.

Replacing the Prefilter Cartridge

1. Turn the unit OFF, then shut off the inlet water supply.

2. Unscrew the filter bowl.

3. Remove the old cartridge.

4. Clean the filter bowl with a damp cloth, rinse thoroughly.

5. Remove the wrappers from a new cartridge (10” P/N 00403232, 20” P/N 01000222). Install the cartridge in the
bowl, making sure it seats in the bottom of the bowl.

6. Check the O-ring seal for dryness and cuts. Replace the seal if necessary and use silicone lube as needed.

CAUTION! Do not use petroleum-based lubricants, which destroy the synthetic rubber seal.

7. Screw the filter bowl back onto the filter head.

8. Turn on the inlet water supply.

Membrane Replacement

Replace an element that has been damaged or cannot be cleaned. (Refer to Figure 26).

1. Turn off the system. Allow pressure to be completely relieved. Turn main feed line to RO off.

2. Remove retaining clips from both ends of all vessels.

3. Remove end caps from all vessels, with the tubing remaining in place. Note placement the caps to assure re­installation in the same orientation.

4. Remove the RO element from the housing. Note orientation of membranes to assure re-installation in same
orientation. Brine seal will be facing the incoming feed to the vessel. Flow direction is indicated by the arrow on
the outside of the membrane vessel.

5. Check the o-ring seals on the element and end plug, and the element brine seal for damage. If an O-ring is cut
or crimped, it may have caused high flow and poor quality. Replace the O-rings and retest before replacing the
entire element.

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

CAUTION! DO NOT use a petroleum-based lubricant, because it will damage the synthetic rubber

and the membrane.

7. Make sure the brine seal is located in the direction of the incoming feed to that vessel according to the flow
arrow and the original membrane orientation.

Testing Modules

If the product flow calculations or NFLOW values show a loss of flow, or the product quality has become poor, one or
more elements will require cleaning or replacement. Because poor performance might be due to only one element, test
the product flow and quality from individual housings.

To test each element:

1. Disconnect the product tubing from the housing to be tested.

2. Choose GO TO RUNNING from the main menu.

3. Measure the product flow and TDS from the test element.

4. Choose GO TO OFFLINE from the main menu.

5. Reinstall the tubing.

6. Continue testing the elements as needed to determine which should be cleaned or replaced.

Cleaning Modules

During the operation of any reverse osmosis system, dissolved solids and particulate matter are concentrated inside the
module element. If these contaminants are present in relatively low concentrations, the concentrate flow from the system
flushes them to drain. In most cases, water pretreatment such as filters and softeners will prevent the deposit of these
contaminants.

When these deposits occur, there will be a decrease in the product water flow and quality. When these symptoms be­come excessive, the modules must be cleaned before they are permanently damaged.

To determine when cleaning is needed, compare the current system performance to the performance of the system when
the reverse osmosis elements were new. Use Table 7 to obtain data and compare the performance of the system, “new”
and “now” (record the data in pencil).

Table 7. System performance—new vs. present.

NOTICE If new data is not available, use the specifications listed earlier in these instructions. However,

keep in mind that the new elements may have exceeded these specifications, so performance may
have decreased even if the unit still exceeds specifications.

In addition to differences in product flow and quality (TDS), determine whether there were any changes in concentrate wa­ter flow, feed water TDS, feed water temperature and feed or product pressures. Changes in these values provide clues
to indicate the cause of any problems with the product water.

If there were changes in feed water temperature or pressure, the product water flow rates will have to be converted to flow
rates under standard conditions (77° F and 200 psig) in order for any comparison to be valid. Refer to the Product Flow
Calculation section to calculate flow rates under standard conditions, then compare the converted values. A decrease in
the product water flow may have been due only to a decrease in temperature or pressure, in which case cleaning would
not be indicated.

If any change in the performance of the elements was not due to a change in operating conditions, it may be time to clean
the elements. In general clean the elements:

1. When the product flow rate decreases by 10% (or when the feed pressure must be increased by 10% to main­tain the same product flow), or

2. When the percent of rejection decreases below specification.

NOTICE Replace the prefilter cartridges if they are discolored by iron.

NOTICE Because strong chemicals are used to clean the elements, maintenance cleaning is not recom-

mended. If the elements need to be cleaned frequently (more than twice a year), the pretreatment
may be inadequate. Obtain a current water analysis and test the Silt Density Index and the Total
Chlorine level of the water on-site to review what changes in pretreatment may be needed.

When cleaning is required, the type of material which is fouling the element should be identified, if possible. Refer to
Table 8 to determine the possible causes of the performance change.

Percent

Rejection

Low Hardness Scale Hardness Scale (light) or Iron Membrane Damage

High Silt or Biofouling — Membrane Damage (light)

For example, if the product flow is low but the percent rejection is normal, the likely causes of the problem are silt or
biofouling. Please note that if the product flow rate has increased (with no increase in temperature or pressure) the likely
reason is damage to the membrane, which cannot be repaired by cleaning.

Once the foulant has been identified, choose the recommended cleaning chemical(s) from Table 9.

Membrane Problem Cleaning Chemical

Hardness Scale Hydrochloric acid, phosphoric acid

Iron Hydrochloric acid, phosphoric acid

Silt Phosphoric acid and sodium hydroxide

Biofouling Phosphoric acid and sodium hydroxide

Table 9. Recommended membrane cleaning chemicals.

Because phosphoric acid can be used by itself or in combination with sodium hydroxide to clean almost all types of fou­lants, it is generally recommended over hydrochloric acid when choosing a “stock” acid.

NOTICE Some municipal surface water supplies are treated with alum. Aluminum fouling results in low flow

and, occasionally, in low rejection. If aluminum fouling is suspected, use only hydrochloric acid.

Use a pH meter to prepare acid and caustic solutions, and to monitor pH changes as the solutions react with any foulants.

Materials required:

1. Solution tank (50 gallon capacity, minimum), to prepare and store the chemical solution.

2. Tank stand, to elevate solution tank to level above pump.

CAUTION! The bottom of the tank must be higher than the pump on the RO unit to prevent cavita-

tion of the pump when solution is drawn from the tank.

3. Tubing 1/2” O.D. to connect cleaning adapter ahead of Pre-filter.

4. A pH meter.

5. A pre-filter cartridge (P/N 00955004).

Before proceeding record the “NOW” values in Table 7 on page 66.

Prepare the Equipment for Cleaning

1. Choose GO TO OFFLINE from the main menu.

2. Place the solution tank on the tank stand. Connect the tubing to the cleaning adapter then place the other end

of the tubing at the bottom of the solution tank.

NOTICE The tubing length should be as short as possible to prevent excessive pressure drop. Cut the tub-

ing as required to minimize the length.

3. Remove the product tubing from the service connection and place the end in the solution tank. The concentrate

tubing should still be directed to drain.

4. Replace the Pre-filter cartridge.

5. Choose GO TO RUNNING from the main menu.

6. Fill the tank with 30-40 gallons of RO product water.

CAUTION! DO NOT turn on the RO system unless water can flow from the product and waste

lines.

NOTE Soft water is an acceptable substitute for RO water. When the solution tank is filled, direct the product

tubing to drain. Next, open the pump system pressure control valve until the system pressure is ap­proximately 50 psig.

Cat. No. 01023095

Service and Maintenance 67

7. Choose GO TO OFFLINE from the main menu. Remove wires from terminals 3 and 4 (Pressure switch) and
install a jumper wire across those two terminals.

8. Open the cleaning valve to allow feed water to displace air in the cleaning tubing, then close the inlet water
shutoff valve.

Clean the Tank

1. Choose GO TO RUNNING from the main menu.

CAUTION! If the pump is noisy, cavitation is occurring and the pump will be damaged. Turn the

power switch OFF and check for any obstructions to flow. Reduce the pump pressure
as required to prevent cavitation.

2. Record the pump pressure and measure the product water flow at low pressure. This flow will be used to esti­mate if cleaning has been successful. Turn the power switch to OFF.

3. Add enough acid to the solution tank until the pH is between 2.0 and 2.5.

NOTE If the foulant to be removed is silt or a biofilm, use phosphoric acid.

WARNING! Acid and Sodium Hydroxide are strong chemicals that must be handled carefully to

avoid injury. Wear protective clothing and have a source of water nearby to flush any
spills.

CAUTION! Local codes may prohibit the discharge of acid and caustic solutions to drain. If

necessary, an extra tank can be used to neutralize the solutions before discharging to
drain.

4. Choose GO TO RUNNING from the main menu. After approximately 5 gallons have been drawn from the solu­tion tank, Choose GO TO OFFLINE from the main menu.

5. Allow elements to soak for 15 minutes. Choose GO TO RUNNING from the main menu. Draw another 5 gallons
from the solution tank. Choose GO TO OFFLINE from the main menu.

6. Remove the end of concentrate tubing from the drain and place it in the solution tank.

7. Choose GO TO RUNNING from the main menu. Allow the acid solution to circulate for 30 minutes. During recir­culation, monitor the pH of the solution. If the pH rises above 3.0, add acid to reduce the pH to 2.0.

CAUTION! The temperature of the chemical solution will rise as it is recirculated. If the tempera-

ture exceeds 95°F, turn the power switch to OFF and allow the solution to cool to
prevent damage to the RO elements.

NOTE A plastic gallon jug filled with ice may be placed in the solution to cool it.

8. When 30 minutes have passed, adjust the system pressure to the pressure recorded in Step 9. Measure the
product flow rate, then compare this flow to the flow recorded in Step 9. If cleaning is successful a noticeably
higher product flow should now be observed.

9. Choose GO TO OFFLINE from the main menu. If the cleaning was for removal of hardness scale or iron only,
go to “Finish Cleaning Procedure” on page 69.

Clean Silt or Biofouling

1. If the cleaning was for silt or biofouling, take a 250 ml sample of phosphoric acid solution and carefully add
sodium hydroxide until the pH is at least 12. If the solution turns cloudy, it contains hardness and/or iron.

68 Culligan® Series M2 Reverse Osmosis

68 Cat. No. 01023095

Discard the contaminated acid and prepare a fresh 30 gallons of phosphoric acid solution.Add sodium hydroxide
to the phosphoric acid solution. The pH of the solution should be increased to 11.0-11.5.

NOTE The result is an alkaline solution of tri-sodium phosphate (TSP), a common ingredient in detergents.

2. If the solution remains clear, then direct the concentrate tubing to drain, then choose GO TO RUNNING from

the main menu. Check that the unit is drawing chemical solution.

CAUTION! If the pump is noisy, cavitation is occurring and the pump will be damaged. Choose

GO TO OFFLINE from the main menu and check for any obstructions to flow. Reduce

the pump pressure as required to prevent cavitation..

3. After approximately 5 gallons have been drawn from the solution tank, choose GO TO OFFLINE from the main

menu.

4. Allow the elements to soak for 15 minutes. Turn the power switch to ON. Draw another 5 gallons from the solu-

tion tank. Choose GO TO OFFLINE from the main menu.

5. Remove the end of concentrate tubing from the drain and place it in the solution tank. Choose GO TO

RUNNING from the main menu. Allow the alkaline solution to circulate for 30 minutes. During recirculation moni­tor the pH of the solution. If the pH drops below 10.0 add sodium hydroxide to increase the pH to 11.5.

NOTE If the caustic solution becomes dark brown (like coffee), it probably is saturated with organic material.

Discard the solution and prepare a fresh batch of phosphoric acid and sodium hydroxide.

For more accurate testing, use a Hach Model DE-2 detergent test kit or equivalent to ensure that the
product water is less than 0.05 ppm detergent.

A plastic gallon jug filled with ice may be placed in the solution tank to cool the solution.

CAUTION! The temperature of the chemical solution will rise as it is recirculated. If the tempera-

ture exceeds 95°F, choose GO TO OFFLINE from the main menu and allow the solution
to cool to prevent damage to the RO elements.

Finish Cleaning Procedure

1. When 30 minutes have passed, adjust the system pressure to the pressure recorded during low pressure.

Measure the product flow rate, then compare this flow to the flow recorded during low pressure. If cleaning is
successful a noticeably higher product flow should now be observed.

2. Choose GO TO OFFLINE from the main menu. Remove the concentrate and product tubing from the solution

tank and direct them both to drain. Choose GO TO RUNNING from the main menu to draw most of the remain­ing cleaning solution from the tank.

CAUTION! Do not allow the unit to draw air from the tank, or the pump will be damaged.

3. Choose GO TO OFFLINE from the main menu. Close the cleaning valve, reconnect the wires to the pressure

switch, then open the feed water valve.

4. Choose GO TO RUNNING from the main menu and flush the cleaning solution from the unit for 30 minutes or

until the pH levels of the concentrate water and the product water remain constant.

CAUTION! Soft water must be used to flush the caustic solution, or hardness will precipitate. If

soft water is not available, use temporary portable exchange softener tanks.

Service and Maintenance 69

5. Adjust the system pressure to the normal value. Measure all flows, TDS levels, pressures, and temperature.
Compare these values with the “new” and “now” values to determine if cleaning has been successful. If clean­ing has not been successful, contact the service department at Culligan International Company for suggestions
on alternate cleaning chemicals. If cleaning has been successful, note which chemicals were effective. Use the
same chemical(s) when the unit is cleaned again.

6. Replace the Pre-filter cartridge.

7. After cleaning and rinsing have been completed, connect the product tubing to the service line. Remove the
jumper installed and reconnect the pressure switch. Rinse the cleaning tank and tubing with fresh water.
