OVERVIEW

Water quality and component overview

WATER QUALITY

Supply water must be softened and dechlorinated before being supplied to the reverse-osmosis system. If water is not properly dechlorinated or softened, it can damage reverse osmosis membranes. If you are not installing DriSteem water pretreatment components, verify that your water has had chlorine removed and is softenened.

DECHLORINATOR REMOVES CHLORINE

The dechlorinator removes chlorine from supply water before it enters the reverse osmosis membranes.

Supply water enters the dechlorinator and passes through a charcoal sieve, which neutralizes chlorine before entering the water softener. The dechlorinator is automatically backﬂ ushed whenever a programmed calendar date or water meter usage is met. During automatic backﬂ ushing, clean water ﬂ ows through the dechlorinator to rinse the charcoal, and then ﬂ ows to drain (tank dechlorinators only).

WATER SOFTENER REMOVES CALCIUM, MAGNESIUM, AND IRON

The water softener removes dissolved hard water minerals from supply water before it enters the reverse osmosis membranes.

Water passes from the dechlorinator into the softener where dissolved minerals are removed by an ion-exchange process. Softened water exits through a water meter to enter the reverse osmosis membranes. When the water meter ﬂ ow setpoint is satisﬁ ed, the softener will take brine from the brine tank to regenerate the resin. Water will be rejected to drain during this period of rinsing.

REVERSE OSMOSIS MEMBRANES ELIMINATE REMAINING MINERALS AND ORGANICS

CAUTION

Dissolved minerals and organics must be eliminated from the water in order to keep system components operating properly. Potable water passes through a dechlorinator and duplex water softener to take out chlorine and hard water deposits. The softened water enters the RO station, then ﬂ ows through a 5 micron ﬁ lter cartridge. Thereafter, a multi-stage pump pressurizes the water to

Water supplied to the reverse-osmosis system that does not meet the required water quality standards will cause premature component failure and void the DriSteem warranty.

approximately 125 psig (860 kPa), depending on the quality of water and the desired ﬂ ow. Then, water is forced to cross a reverse-osmosis membrane, which removes most dissolved minerals. The water is now puriﬁ ed and contains very few minerals (typically less than 10 ppm) and is then stored in the pressurized storage tank. A portion of the rejection water may be recirculated; the rest, which is saturated with minerals, is sent to the drain.

COMPONENT OVERVIEW

Your system may include all or some of the following components.

• Water pretreatment components

- Dechlorinator (tank style ﬂ oor mount recommended on all sizes, cartridge style wall mount available for RO models 401 and 402)

- Single or duplex water softener and brine tank

• RO storage options include:

- Pressurized RO holding tank

- Atmospheric RO holding tank with UV sterilization and booster pump

DRISTEEM WATER TREATMENT SYSTEMS INSTALLATION, OPERATION, AND MAINTENANCE MANUAL

Water quality and component overview

OVERVIEW

DESIGN BASIS

• Systems rated at: 50°F (10°C) using 1000 PPM sodium

chloride solution operating at 200 psi pressure.

• Minimum feed pressure to RO System: 40 PSI. System

capacity changes signiﬁ cantly with water temperature. For higher TDS a water analysis must be supplied and could result in modiﬁ cations to the system.

• Chlorine must be removed if present in feed water prior to

RO with a dechlorinator.

• Water must be pretreated with a softener to avoid scaling

the membranes.

• Feed water turbidity: Less than 1 NTU; Feed water

silt density index (SDI): 3 maximum. If exceeded, pretreatment with media ﬁ lter recommended. All pretreatment equipment are available from DriSteem.

• Capacity Basis: 24 hrs/day

DESIGN NOTES

1. Pump flow/Feed flow: The pump has been designed to include recycle flow (if any) coming back to the pump inlet from the concentrate stream based on desired recovery. The sum of permeate flow, concentrate flow and recycle flow (if any) will equal the pump design flow.

Important:

• System pressure is a variable. It is important to adjust the pressure to get the correct permeate and concentrate flows. The exact value of the pressure is not important.

• Permeate flow will increase at higher temperature.

CAUTION

Damage to pump

Do not close the valve. Do not operate the pump below minimum combined ﬂ ow rate (permeate + concentrate + recirculating).

Models 401-402: 4 gpm (15.2 L/ min) Models 403-412: 6 gpm (22.7 L/min)

2. Permeate flow: Indicates design flow rate from RO membranes as product water for use.

3. Concentrate flow: Water flowing to the drain. Concentrate flow is critical for proper system operation.

4. Recycle flow: Flow stream that returns from the concentrate line back to the pump intake, rather than to the drain.

System piping

PLUMBING

Plumbing materials can signiﬁ cantly contribute to the contamination of the water. Care must be exercised over the choice of thread sealants. PTFE tape is suitable for all threaded connections in this system. Pipe dope can leach objectionable impurities into the water and must be avoided.

FEED WATER CONNECTION

Connect the raw water supply to the inlet of the solenoid valve, observing the following:

• The line size shall be ¾ inches (19 mm) or larger to minimize pressure loss.

• A manual valve should be installed on this line to shut off the water supply if it will ever be needed. Be sure that this valve in no way restricts the water ﬂ ow when it is fully open.

• Water supply min pressure 40 psi (276 kPa). A pressure regulator may be required if pressure is above 70 psi (483 kPa).

CAUTION

This unit produces high quality water which could cause corrosion or leaching of the plumbing following the system. Use only plumbing components of inert material that are compatible with the application. Copper plumbing cannot be used.

Important:

All plumbing is to be done in accordance with state and local codes.

CAUTION

CONCENTRATE/REJECT CONNECTION

Connect a line to the single point drain outlet on the skid. The drain must have a minimum capacity which meets or exceeds the combned output of all system drains.

PERMEATE/PRODUCT WATER CONNECTION

Connect the product water line to the product connection point on the system. Run this line to your storage tank or other downstream equipment, observing the following:

• Run this line in such a manner as to minimize static head pressure in the product line.

• The product line should have no restrictions to the product ﬂ ow.

• Inspect to insure that no ﬂ exible pumping lines have been kinked or damaged during installation.

RO membranes will fail immediately if the product water is allowed to ﬂ ow backward into the elements.

CAUTION

The highest point of the tubing should not be higher than four feet above the top of the RO modules, or the elements may be damaged.

CAUTION

Do not fully close the manual valve located directly after the RO pump. This could cause cavitation and premature pump failure.

CAUTION

DRISTEEM WATER TREATMENT SYSTEMS INSTALLATION, OPERATION, AND MAINTENANCE MANUAL

Damage to pump

Do not close the valve. Do not operate the pump below minimum combined ﬂ ow rate (permeate + concentrate + recirculating).

WIRING

• Ladder style wiring diagrams (included with unit, separate from this manual)

show power, control, and equipment-to-control-cabinet interconnection requirements.

Note: If using a ﬁ eld supplied ﬂ oor water leak switch (terminals P15-3 and

P15-4) remove factory jumper from the control board.

• External connections diagrams (included with unit, separate from this

manual) show connection points to the microprocessor-based controller and wire terminals for external safety and control devices.

All wiring must be in accordance with all governing codes and with wiring diagrams.

ELECTRICAL INSTALLATION

Wiring and branch circuit protection is provided by the installer per NEC (or IEC 60364 in Europe) requirements.

For power supply and machine ground con nec tions, size the wire using the 75 °C wiring table, per NEC (or IEC 60364 in Europe) requirements. Then use copper conductors rated for a 105 °C en vi ron ment. The wiring from the control cabinet to the equipment must be rated for 105 °C.

Verify electrical current characteristics (voltage, phase and amp draw) and capacity requirements against those listed on the name plate.

SERVICE DISCONNECT

A service disconnect must be installed per NEC requirements and governing codes.

PREVENTING ELECTRICAL NOISE

INSTALLATION

WARNING

Electric shock hazard

Only qualiﬁ ed electrical personnel should perform ﬁ eld wiring installation procedures. Improper wiring or contact with energized circuits can cause property damage, severe personal injury, or death as a result of electric shock and/or ﬁ re.

Do not open control cabinet, pump motor, or subpanel access panels until electrical power is disconnected.

CAUTION

Damage from debris

When drilling penetrations in the control cabinet, protect all internal components from debris, and vacuum out the control cabinet when ﬁ nished. Failure to comply with this directive can damage sensitive electronic com po nents, cause erratic operation or failure, and void your DriSteem warranty.

Electrical noise can produce undesirable effects on electronic control circuits, thereby affecting controllability. Electrical noise is generated by electrical equipment such as inductive loads, electric motors, solenoid coils, welding machinery, or ﬂ uorescent light circuits. The electrical noise or interference generated from these sources (and the effect on controllers) is difﬁ cult to deﬁ ne, but the most common symptoms are erratic control or intermittent operational problems.

Most electrical noise problems can be prevented by using proper wiring practices and techniques to prevent coupling or inducing of electrical interference into control circuits. The following wiring practices should minimize interaction of noise and controls:

• Connect unit and control cabinet to a code approved earth ground.

• Separate the line voltage wiring from low voltage control circuit wiring

when routing electrical wiring inside the control cabinet.

DRISTEEM WATER TREATMENT SYSTEMS INSTALLATION, OPERATION, AND MAINTENANCE MANUAL

Important:

Failure to follow these wiring procedures can result in erratic operation or failure.

This product has been tested at the factory for proper operation. Product failures resulting from faulty handling, incorrect wiring, or shorting of wires together on external components are not covered under your DriSteem warranty. Review information and di a grams before proceeding.

Page 22

INSTALLATION

Connecting components

GROUNDING REQUIREMENTS

The approved earth ground must be made with solid metal-to-metal connections and must be a good con duc tor of radio frequency interference (RFI) to earth (multistranded conductors).

Ground wire should be the same AWG (mm2) size as the power wiring or sized per NEC requirements (in Europe, IEC 60364 requirements).

When the control cabinet is mounted remotely from the unit, a ground wire is necessary from the machine ground lug on the unit to the machine ground lug in the control cabinet. The bonding machine ground wire should be the same AWG (mm2) as the largest heater wire or sized per NEC or IEC 60364 requirements.

CAUTION

On three-phase units ensure proper supply line voltage wiring. Incorrect wiring will cause the RO pump to run backwards and void your DriSteem warranty.

OPERATION

Start-up checklist

If an item in the Start-up checklist below does not apply to your system, skip to the next item and continue the process.

☐ Read this manual and all other information that was provided with your system. ☐ Verify that all ﬁ eld wiring is done according to the instructions in this manual and in the unit wiring diagram. ☐ Conﬁ rm that proper grounding and an approved earth ground are provided. ☐ Conﬁ rm that the keypad/display is mounted with its modular cable routed away from high-voltage circuits and

connected to the Display connector on the Vapor-logic board.

☐ Install cartridge ﬁ lter and check for leaks. (See “System Piping” on Page 20.) ☐ Precharge pressurized RO storage tank to 28 psi (195 kPa).

Note: This precharge pressure is for pressurized RO storage tank cut-in and cut-out switch points at 30 and 50 psi

(210 and 345 kPa) respectively.

☐ Turn on the water supply, and conﬁ rm there are no leaks. ☐ Turn on power to the unit, and conﬁ rm the Main menu is displayed on the keypad/display. The display may take

several seconds to appear as the controller powers up.

☐ Conﬁ rm in the Main Menu that the mode is “Auto” and that status is “Idle.” ☐ When “Idle” appears in main menu, conﬁ rm that the inlet pressure is at least 40 psi (276 kPa) on the display. ☐ With sufﬁ cient water available, the system in Auto mode, and the storage tank pressure less than 30 psi (210 kPa),

verify that the pump is activated.

☐ Set perm ﬂ ow and recirc ﬂ ow meter to desired setting. ☐ Systems with tank-style carbon ﬁ lter with control valve: Ensure that elastomeric Drain Line Flow Control restrictor

washer is installed correctly in drain outlet plumbing assembly. This is required to prevent overﬂ ow and potential

carry-over of carbon to the drain system. See “Dechlorinator” on Page 18 of this manual. ☐ If you experience difﬁ culties, have the keypad/display information available along with the serial number and unit

Model, and call DriSteem Technical Support at 800-328-4447. Note: Instructions on how to properly care for the freeze protect chemical that is shipped with the system is available

OPERATION

Start-up

START-UP PROCEDURE

Check component installation per the layout shown in Figure 14-1 (depending on your model). After all components are installed and connected properly:

1. Perform all applicable “Start-up checklist” items on Page 23.

2. Read and follow instructions in the “Operation” section of Vapor-logic Installation and Operation Manual.

Note: During start-up, do not leave the system unattended.

TEST OPERATION

Using the keypad/display or web interface, place the zone controllers (if DriSteem controlled) and pump station in Auto mode. For each zone, perform the following procedure:

If the system has a full RO holding tank, create a call for water by draining

water from the tank until the pressure falls below 30 psi (210 kPa).

3. Monitor system performance, and watch for leaks.

4. If a leak is found: a. Remove demand signal, and put the system in Standby mode. b. Tighten any loose connections. c. Return system to Auto mode. d. If a leak persists, replace tubing or ﬁ tting that is leaking.

Important

If the system is not in operation within six months of shipment, it is strongly recommended to use an organic cleaning cartridge prior to performing the start-up checklist to ensure proper operation. See page 36 for information and part number.

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. Leave system in Auto mode. It will automatically refill the RO holding tank when pressure falls below 30 psi (210 kPa).

INITIAL SYSTEM START-UP

1. Close the manual valves to both the RO holding tank and all downstream equipment. Open the manual valve leading to the drain.

2. Open the feed water supply valve.

3. Open the system pressure (pump throttle) control valve fully counterclockwise (if applicable). Open the concentrate control valve fully counterclockwise. Close the recycle valve.

4. Put the system into 'Auto' mode. Note inlet water pressure must be at least 40 psi (276 kPa).

5. If incoming pressure is too high, an inlet pressure regulator (not included) may be installed. This should be set at 40 psi (276 kPa).

6. Some fittings may have loosened during shipment. Check for leaks at all tube fittings and threaded joints.

7. Allow the unit to run for at least 30 minutes to flush the preservative solution from the system.

DRISTEEM WATER TREATMENT SYSTEMS INSTALLATION, OPERATION, AND MAINTENANCE MANUAL

Page 25

Start-up

OPERATION

8. Once the preservative solution has been flushed from the system, shut

down the system by putting the system into 'Standby' mode on the Vaporlogic keypad and close the manual valve going to the drain. Open the manual valves to both the RO storage tank and downstream equipment.

9. Put the system back into 'Auto' mode.

10. Adjust the throttle valve to get the specified permeate flow (if applicable).

11. Adjust the concentrate valve and recycle valve until the specified permeate

flow and recycle flow are obtained. It may be necessary to readjust the throttle valve. See Table 26-1.

12. Test the operation of the pressure switch by slowly closing the inlet water

supply valve. The unit should shut off after a short 5 second time delay.

13. Once all the desired flows are set, allow the system to run for

approximately 30 minutes. Then record the performance information using the system operation data log on page 42. The values recorded at startup will be important for determining system performance at a later date.

OPERATING DO'S AND DONT'S

1. Change the cartridge filters regularly

2. Monitor the system and keep a log daily

CAUTION

Do not operate the system with the control valve closed.

Important:

By setting 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 be run continuously when possible, rather than go through frequent start/stop cycles.

CAUTION

Damage to pump

Do not close the valve. Do not operate the pump below minimum combined ﬂ ow rate (permeate + concentrate + recirculating).

Models 401-402: 4 gpm (15.2 L/ min) Models 403-412: 6 gpm (22.7 L/min)

3. Run the system, as much as possible, on a continuous basis.

4. Adjust the system recovery to the recommended value

DON’T

1. Permit chlorine in the feed water.

2. Shut down the system for extended periods. If system will be down for

more than one month, treat the system with a membrane preservative. See page 37 for instructions.

3. Close the throttle valve completely.

4. Operate the system with insufficient feed flow.

OPERATION

System operation

SHUTDOWN

1. Put the system in 'Standby' mode or remove power. Close the isolation valve if it is installed on the feed line.

2. If the unit is to be shut down for more than one week, a membrane preservative should be used. To accomplish this, perform 30 second flush using cartridge filter insert (see page 24 and 36 for more information). After 30 seconds, press the power button OFF, and close the concentrate valve. This will hold the preservative in the pressure vessel.

3. When the system is restarted after an extended shutdown, follow initial system start-up procedures.

Maintenance information

MAINTENANCE

MAINTENANCE TIPS

Maintain proper operating conditions:

• Do not exceed 60-90 psi (414-620 kPa)on the system inlet pressure gauge.

• Do not over use recycle ﬂ ow. This can cause premature scaling of the

membrane. A proper concentrate ﬂ ow is required for a long membrane life. See page 10 for maximum recycle ﬂ ow.

• To ensure no chlorine reaches the RO membranes, test the water from your

dechlorinator periodically for chlorine break through.

WHEN TO CHANGE SEDIMENT FILTERS

Sediment ﬁ lters should be changed regularly to maintain proper pressure and ﬂ ow.

Change the ﬁ lters when the difference between ﬁ lter pressure gauge increases by 10 psi over the initial pressure difference. For example, if initial readings are 60 psi in and 58 psi out, the difference is 2 psi. Therefore, when that difference reaches 12 psi, it is time to replace the sediment and carbon cartridges.

WHEN TO CLEAN MEMBRANES

In normal operation, the membrane in reverse osmosis elements can become fouled by mineral scale, biological matter, and grime. These deposits build up during operation until it causes loss in water output or loss of salt rejection, or both. Elements should be cleaned or replaced whenever the water output rate drops by 10 percent from its initial ﬂ ow rate (the ﬂ ow rate established during the ﬁ rst 24 to 48 hours of operation) or when TDS in the product water (permeate) rises above 50. Use the factory mounted TDS sensor located on the right side of the system.

FIGURE 33-1: SEDIMENT FILTER

DriSteem replacement part

• 2½" x 20" - Model 401-404 (part number: 550026-003)

• 4" x 20" - Model 406-412 (part number: 550026-004)

It should be noted that the water output rate will drop if feed water temperature decreases (about 1.5% per °F). This is normal and does not indicate membrane

fouling. A malfunction in the pretreatment, pressure control or pump can cause a drop in feed water delivery pressure, feed water ﬂ ow, product water output, or an increase in salt passage. If such adjustments are needed, the element may not require cleaning.

MEMBRANE CLEANING AND PRESERVATIVE CARTRIDGES

• Clean and preserve membranes without removing them from your system

• Reduce downtime

• Maintain your system performance at a higher level

• Prolong membrane life by regular use of cleaning cartridge

SEDIMENT PRE-FILTER CARTRIDGE

WHEN TO CHANGE SEDIMENT PREFILTER CARTRIDGE

Sediment ﬁ lters should be changed regularly to maintain proper pump pressure and ﬂ ow. If the pressure drop across the cartridge ﬁ lter (as indicated by the differential between the ﬁ lter inlet and ﬁ lter outlet pressure gauges) increases by 10 psi, the sediment ﬁ lters should be changed.

CHANGING CARTRIDGE FILTERS

1. Put the system into 'Standby' mode and shut down the RO system.

2. Close inlet supply valve.

3. Un-assemble the filter housing (twist the sump counter-clockwise).

4. Remove and inspect the cartridge. Replace as needed.

5. Before replacing housing, insure that O ring seal is lubed and placed in groove of housing. Inspect seal and replace as needed.

6. Assemble housing (turn the sump clockwise into the cap until tight).

Components

GAUGES AND VALVES

Verify proper operation by visual inspection during operation.

DECHLORINATOR

1. Visually inspect components for leaks or breakage.

2. Monthly, have a water sample taken after dechlorinator to check for

chlorine. If 2 ppm or greater, replace carbon media.

WATER SOFTENER

1. Check brine tank salt level at least weekly. Maintain salt level above the

half-full mark at all times. Note: DriSteem recommends using pulverized salt because it dissolves

easily.

2. Visually inspect all components for leaks or breakage.

3. Annually, have a water sample taken downstream from water softener to

check for hardness. If water hardness is 15 ppm or greater, make sure there is salt in brine tank. If there is salt, and water hardness if 15 ppm or greater, contact DriSteem for water softener resin replacement.

MAINTENANCE

4. See water softener service manual for recommended service.

PRESSURIZED RO HOLDING TANK

1. Precharge pressurized RO holding tank with air to 26 to 28 psi (180 to

195 kPa) using Schrader valve on top of the tank.

2. Set pressurized RO storage tank to cut in at 30 psi (210 kPa) and cut out

at 50 psi (345 kPa). See instructions that shipped with Pressurized RO holding tank and RO station interface kit.

3. Check cut-in and cut-out pressures as follows:

Drain pressurized RO holding tank until RO generation cycle begins. Verify that starting and stopping pressures are approximately 30 psi and 50 psi (210 and 345 kPa) respectively.

System operation temperature

DriSteem rates reverse-osmosis systems at 50°F (10°C). This is lower than the industry standard of 77°F (25°C).

To ﬁ nd the membrane permeate rate at a different temperature, follow these steps:

1. Find the temperature correction factor (TCF) from the below table.

2. Multiply the rated permeate flow from Table 10-1 on page 10 by

the temperature correction factor.

The result is the permeate ﬂ ow at the desired temperature.
