Notes
Changes in operating variables are beyond the control of Watts. The
end user is responsible for the safe operation of this equipment.
The suitability of the product water for any specific application is the
responsibility of the end user.
Successful long-term performance of an RO system depends on
proper operation and maintenance of the system. This includes
the initial system startup and operational startups and shutdowns.
Prevention of fouling or scaling of the membranes is not only a matter of system design, but also a matter of proper operation. Record
keeping and data normalization are required in order to know the
actual system performance and to enable corrective measures when
necessary. Complete and accurate records are also required in case
of a system performance warranty claim.
Changes in the operating parameters of an RO system can be
caused by changes in the feed water or can be a sign of trouble.
Maintaining an operation and maintenance log is crucial in diagnosing and preventing system problems. For your reference, a typical log
sheet is included in this manual.

I. Introduction
The separation of dissolved solids and water using RO membranes
is a pressure driven temperature dependent process. The membrane
material is designed to be as permeable to water as possible while
maintaining the ability to reject dissolved solids.
The main system design parameters require the following:
• Internal flows across the membrane surface must be high enough
to prevent settling of fine suspended solids on the membrane
surface.
• The concentration of each dissolved ionic species must not exceed
the limits of solubility anywhere in the system.
• Pre-treatment must be sufficient to eliminate chemicals that would
attack the membrane materials.

Notes:
•Maximum production based on a feed water of 77° F, SDI < 3,
1000 ppm TDS, and pH 7.6.
Individual membrane productivity may vary (± 15%). May be
operated on other feed waters with reduced capacity.
•Percent Rejection is based on membrane manufactures specifications; overall system percent rejection may be less.
B. RO Overview
Reverse osmosis systems utilize semipermeable membrane elements to separate the feed water into two streams. The pressurized
feed water is separated into purified (product) water and concentrate
(reject) water. The impurities contained in the feed water are carried
to drain by the reject water.

II. Controls, Indicators, and
Components (See Figure 1)
C. Pretreatment
The RO feed water must be pretreated in order to prevent membrane damage and/or fouling. Proper pretreatment is essential for
reliable operation of any RO system.
Pretreatment requirements vary depending on the nature of the feed
water. Pretreatment equipment is sold separately. The most common
forms of pretreatment are described below.
A. General System Component Identification
Media Filter - Used to remove large suspended solids (sediment)
from the feed water. Backwashing the media removes the trapped
particles. Backwash can be initiated by time or differential pressure.
B Reject Control Valve - Controls the amount of reject flow.
AController - Controls the operation of the system and displays
the product water quality.
CReject Recycle Control Valve – Controls the amount of reject
recycle flow.
Water Softener - Used to remove calcium and magnesium from
the feed water in order to prevent hardness scaling. The potential
for hardness scaling is predicted by the Langelier Saturation Index
(LSI). The LSI should be zero or negative throughout the unit unless
approved anti-scalents are used. Softening is the preferred method
of controlling hardness scale.
D Pump Discharge Valve - Used to throttle the pump.
EPrefilter Inlet Pressure Gauge - Indicates the inlet pressure of the
prefilter.
FPump Suction Pressure Gauge – Indicates the prefilter outlet
and pump suction pressure. The difference between this gauge
and the prefilter inlet gauge is the prefilter differential pressure of
the prefilter.
Carbon Filter - Used to remove chlorine and organics from the
feed water. Free chlorine will cause rapid irreversible damage to the
membranes.
The residual free chlorine present in most municipal water supplies
will damage the thin film composite structure of the membranes
used in this unit. Carbon filtration or sodium bisulfite injection should
be used to completely remove the free chlorine residual.
GPump Discharge Pressure Gauge - Indicates the pump discharge pressure.
HMembrane Feed Pressure Gauge – Indicates the membrane
feed pressure.
I Reject Pressure Gauge - Indicates the reject pressure.
Chemical Injection - Typically used to feed antiscalant, coagulant,
or bisulfite into the feed water or to adjust the feed water pH.
Prefilter Cartridge - Used to remove smaller suspended solids and
trap any particles that may be generated by the other pretreatment.
The cartridge(s) should be replaced when the pressure drop across
the housing increases 5 - 10 psig over the clean cartridge pressure
drop. The effect of suspended solids is measured by the silt density
index (SDI) test. An SDI of five (5) or less is specified by most membrane manufacturers and three (3) or less is recommended.
JReject Flow Meter - Indicates the reject flow rate in gallons per
minute (gpm).
KReject Recycle Flow Meter – Indicates the reject recycle flow in
gpm.
L Product Flow Meter - Indicates the product flow rate in (gpm).
M Prefilter Housing - Contains the RO prefilters.
Iron & Manganese - Iron should be removed to less than 0.1 ppm.
Manganese should be removed to less than 0.05 ppm. Special media filters and/or chemical treatment is commonly used.
NAutomatic Inlet Valve - Opens when pump is on and closes
when the pump is off.
pH - The pH is often lowered to reduce the scaling potential.
P RO Membrane Vessels - Contains the RO membranes.
Silica: Reported on the analysis as SiO2. Silica forms a coating on
membrane surfaces when the concentration exceeds its solubility.
Additionally, the solubility is highly pH and temperature dependent.
Silica fouling can be prevented with chemical injection and/or reducing the recovery.
Q Motor starter / transformer enclosure.
O RO Feed Pump - Pressurizes the RO feed water.

III. Operation
D. Startup
1.Verify that the pretreatment equipment is installed and working
properly. Verify that no free chlorine is present in the feed water.
A. Installation
2. Verify that the controller on/off switch is in the off position.
1.The water supply should be sufficient to provide a minimum of
20 psig pressure at the design feed flow.
3.Close the pump discharge completely then open it one turn.
Note: All valves on this unit turn clockwise to close.
2.Proper pretreatment must be determined and installed prior to
the RO system.
4. Install five micron filter cartridges in the prefilter housing.
5.Open the reject control valve completely by turning it counterclockwise.
3.A fused high voltage disconnect switch located within 10 feet of
the unit is recommended. This disconnect is not provided with
the RO system.
6.Close the reject recycle control valve completely by turning it
counterclockwise.
4.Responsibility for meeting local electrical and plumbing codes
lies with the owner /operator.
7. Open the feed water shutoff valve installed in step III-B-1 above.
5.Install indoors in an area protected from freezing. Space allowances for the removal of the membranes from the pressure
vessels should be provided. This system requires 42" minimum
clear space on each side.
8.Engage the safety switch or disconnect (installed in step III-C-1
above) to apply electrical power to the RO system.
9.Turn the key switch on by rotating it clockwise. Press the power
button. There will be a 10 second delay and the pump will start.
Press the power button as soon as the pump starts to shut it
down and look at the motor fan as the pump stops to determine
if the pump rotation is correct. The fan should rotate in the direction indicated by the rotation arrow on the pump. Continue with
the startup if the pump is rotating in the proper direction. If the
pump rotation is backwards, reverse the rotation by shutting off
the power and swapping any two of the three power lines connected in step III.C.3 above. Verify correct pump rotation before
continuing with startup.
B. Plumbing Connections
Note: It is the responsibility of the end user to ensure that the
installation is done according to local codes and regulations.
1.Connect the pretreated feed water line to the inlet side of the
prefilter housing. (Figure # 1 item # 1) A feed water shutoff valve
should be located within 10 feet of the system.
2.Temporarily connect the outlet of the product water flow meter
to drain. (Figure # 1 item # 2) The product water line should
never be restricted. Membrane and/or system damage may occur if the product line is blocked.
10.Turn the system on and allow the product and reject water to go
to drain for 15 minutes.
3.Connect the outlet of the reject water flow meter to a drain. (Figure # 1 item # 3) The reject drain line should never be restricted.
Membrane and/or system damage may occur if the reject drain
line is blocked. An air gap must be located between the end
of the drain line and the drain. The use of a standpipe or other
open drain satisfies most state and local codes and allows for
visual inspection and sampling.
11.Adjust the reject control valve, the reject recycle control valve
and the pump discharge valve until the desired flows are
achieved. Closing the reject valve increases the recycle and
product flow and decreases the reject flow. Closing the reject
recycle valve increases the reject and product flow and decreases the recycle flow. Opening the pump discharge valve
increases all of the flows. See the temperature correction table in
the appendix to determine the flow rates for different operating
temperatures.
C. Electrical
12.Allow the product water to flow to drain for 30 minutes.
Note: It is the responsibility of the end user to ensure that the
installation is done according to local codes and regulations.
13.Turn off the system and connect the product line to the point of
use. The product water line should never be restricted. Membrane and/or system damage may occur if the product line is
blocked.
1.A safety switch or fused disconnect should be installed within
10 feet of the system. The disconnect and fuses should be sized
accordingly.
14.Restart the system and record the initial operating data using the
log sheet in the next section.
2.Verify that the disconnect switch is de-energized using a
voltmeter.
15.See the controller section for detailed information about the
controller.
3.Connect the outlet of the disconnect switch to the top of the
motor starter relay. (Figure #1 item Q and Figure #2). Attach the
power supply ground to the controller ground.
4.Do not apply power to the RO unit at this time.
