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

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).
1. 220V/1-phase systems can also operate on 208V/1-phase and 240V/1-phase power.
2. Wiring and branch circuit protection (Type RK1, J, or T fusing) to be provided by installer in accordance with NEC requirements.
3. 40 psi (280 kPa) minimum supply water pressure.

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.

• 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.

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
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
24
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
DO
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).
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.
FIGURE 26-1: CONTROL VALVES
CAUTION
To prevent concentrate from
precipitating and causing irreversible
fouling of the RO membrane, do not
operate the system with the control
valve completely closed.

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

MAINTENANCE
Maintenance continued
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).

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 MONITORING AND RECORD KEEPING
The system should be monitored and all pertinent data recorded on a daily
basis. This includes cartridge fi lter pressure in/out, system pressure in/out,
fl ow and water quality (TDS) in/out. Data is needed to determine operating
effi ciency and for performing system maintenance. The latter includes cleaning
of the membranes, adjusting the operating conditions as well as replacement
of cartridge fi lters and RO membranes.

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.
