RO Installation 7

Plumbing Installation

Refer to the appropriate hydraulic schematic/flow diagram on page 26 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 a 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 upstream 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 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 5) with the addition of a pressure switch which needs
to be wired to the control panel (see page 27 for RO standard wiring). A pressurized water storage kit is available under
part number D1018976.

8 Culligan® Series E2 Plus Reverse Osmosis

8 Cat. No. 01023094

Non-Pressurized Product Water Storage Tank

Pressure Gauge

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 5. 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.

Operation

CP Controller Board

The CP controller board controls the Culligan E1, M1, and E2 commercial RO product lines. This board requires no pro­gramming and has the following capabilities:

• 208-230 VAC single-phase motor up to 1 HP

• Line pressure front side flush prior to startup

• Line pressure front side flush every two hours of continuous make water

• Shut-down upon loss of inlet water pressure and auto-restart

• Power-loss and return auto-restart

• Pretreatment lockout

• Storage tank level (or pressure) switch control

• Diagnostic indicator lights and “Run Now” button

The CP controller is designed for simple control of small RO systems with the following characteristics:

• Inlet pressure switch to detect the presence/absence of feed water pressure to the RO

• Inlet solenoid valve, which is normally closed when the RO is off. The valve opens just prior to startup, remaining

open as long as the RO is in a make-water mode

Controller Behavior when Power First Applied

1. When main power is first applied to the CP controller, the controller will first wait for a one-hour delay. To imme­diately start the system, press the red “Run Now” button on the bottom of the controller. The “Run Now” button
will not work if any of the five events in step 5 are occuring.

2. The controller will then open the RO inlet solenoid valve, waiting for an additional one-minute period. During this
period, feed water under line pressure enters the RO, psses through the pump, flushes through the upstream
(feed water side) of the membranes, and then passes to the drain.

3. Because the line pressure is expected to be fairly low (less 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.

4. 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 begins to produce permeate

water.
b. If there is NOT sufficient pressure, the entire process starts over, beginning with the one-hour delay.
c. As long as there is applied power and water pressure is being supplied to the unit, the RO will repeat

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

5. Once the controller successfully enters the make-water mode, it will continue to operate the pump and produce
RO water until one of the following five events occurs:

• Tank Full switch indication

• Pretreatment lockout indication

• 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 close the inlet solenoid.

6. If the unit has stopped for either tank full or pretreatment lockout conditions, it will remain off until these condi­tions no longer exist. The unit will then reopen the inlet solenoid, wait one minute, and then start the pump to
return to the make-water condition.

7. 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.

8. 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 the 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 minute, the system will return to
make-water mode.

10 Culligan® Series E2 Plus Reverse Osmosis

10 Cat. No. 01023094

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. You must press the Run Now button 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. 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 variation in the feed
water.

7. Slowly close the recirculation valve until the desired 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 (1034 kPa). Excessive pressure will damage the pump and may cause property
damage. Excessive pressure may also damage the membranes, fittings, and tubing,
which may also cause property damage.

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.

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. 01023094

Initial Startup 11

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) and your instruments (I):

a. Feed Water Temperature, °F (I)

b. Feed Water SDI (I)

c. Feed TDS, ppm (I)

d. Inlet Pressure, psig (U)

TCF = Temperature Correction Factor. Refer to Table 1 on page 13 for this value.

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.

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 page 13).

12 Culligan® Series E2 Plus Reverse Osmosis

12 Cat. No. 01023094

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 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: 500 ml/min

2. Measure the feed pressure. Example: 175 psig

3. Measure the product pressure. Example: 35 psig

4. Subtract the product pressure from the feed pressure. Example: 140 psig

5. Divide the product flow by the result from step 4. Example: 500 / 140 = 3.57 ml/min/psi

6. Multiply the result from step 5 by 200. Example: 3.57 x 200 = 714 ml/min

7. Measure the temperature of the feed water, then determine the temperature correction factor from Table 1.

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
50 10 1.71 85 29 0.86
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 1. Temperature Correction Factors

8. Multiply the result of step 6 by the temperature correction factor. Example: 714 ml/min x 1.54 = 1099 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 10% 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)

The Level Control connections are located on the controller board. It is labeled “TANK FULL” on the main circuit board.

This signal is Normally Closed. When OPEN it indicates that the atmospheric storage tank is FULL (or that a Pressurized
storage tank is at FULL PRESSURE.)

Storage Tank Setup When Using a Single High Level Float Switch

Connect the level control (or pressure switch) to the TANK FULL terminals (see Figure 6). 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.

Storage Tank Setup When Using a Pressure Switch

When using pressurized storage, you must use a pressure switch that provides a closed signal when the tank is below the
shut off pressure, such as the switch provided in the Pressurized Water Storage Kit.
