FCI Watermakers MAX-Q+ Installation and operating instructions

FCI WATERMAKERS, INC. 3FCI WATERMAKERS, INC. General
ank you for purchasing FCI Watermakers Reverse Osmosis System. Your choice
of FCI Watermakers proves that quality, crasmanship and performance do matter.
e system you have chosen is of the highest quality, and it is the most advanced
watermaker available today. Over 25 years of experience of engineering and extensive
lab testing has gone into the design of your watermaker. In fact many industry
standards are a result of innovations made by FCI Watermakers, including one‑touch
commands, multiple station operation, remote system control, touchscreen displays,
and automated pressure control. Each component was chosen for its ability to
withstand the marine environment and to provide a lifetime of trouble‑free operation.
Design considerations included noise, size, ease of use and simple maintenance. Its
open‑frame construction allows quick, easy inspections, and it aids in shipboard
or land‑based maintenance without having to move the system from its location.
e intent of this manual is to allow the operator to become familiar with
each component of the reverse osmosis system. By understanding the
function, importance, and normal operation of each watermaker module,
the operator can readily diagnose minor problems. When such problems
rst arise, they usually require minor maintenance and the issue is easily
corrected. However, if le unattended, a problem in one component may
eventually aect the rest of the system and it could lead to further repairs.
FCI Watermakers systems use non‑proprietary membranes that are readily
available worldwide, and the systems are designed to be more tolerant of
water conditions. Your vessel travels around the world and encounters
water that varies in both salinity and particulate. FCI utilizes low RPM
components that allow full function operation in these conditions.
FCI has the most comprehensive warranty on the market. e Max•Q+system
is covered for one year on all non‑consumable parts. A copy of our warranty
is included in this manual. Please read and familiarize yourself with it.
Congratulations on joining an elite group of like-minded boat
and yacht owners, who value their investment and have chosen
the industry’s most reliable and advanced marine reverse
osmosis system available. A great deal of time and eort has
been put into the design and manufacture of your new FCI
Watermakers desalination system. Please take time to read
this entire manual and familiarize yourself with its operation.
It will benet you by insuring long trouble-free operation.

ABOUT SAFETY NOTES
Safety issues requiring users attention are highlighted throughout this manual as follows:
WARNING:
Provides critical information in order to prevent the possibility of injuries and/or death.
CAUTION:
Provides important information to prevent the possibility
of damaging the device or equipment.
NOTE:
Provides additional information to safely and properly operate the equipment.
NEW SYSTEM PERFORMANCE
Although each system has been fully tested prior to shipping, there will be a
break‑in period. During this period, approximately 48 hours, the pumps and
membrane performance will change or settle. Small adjustments will need to be
made to the high‑pressure valve and the water quality and quantity will vary.
For installations without APC, the high‑pressure valve will need to be increased
(turned clockwise) and the water quality produced will improve over this break‑
in period. For systems with APC, this adjustment will be automatic.

FCI WATERMAKERS, INC. 5FCI WATERMAKERS, INC. General
BOUNDARY LAYER / CONCENTRATION POLARIZATION
When water permeates through the membrane, nearly all the salt is le
behind in the brine channel. In any dynamic hydraulic system, the uid
adjacent to the wall of the vessel is moving relatively slow. Even though
the main body of the stream is turbulent, a thin lm adjacent to the wall
(membrane) is laminar. is thin lm is called the boundary layer.
If the feed water ow is insucient, the salts are saturated at the boundary layer
and can readily adhere to and pack into the R.O. membrane element surface.
For this reason, it is important to maintain sucient feed water ow through
the R.O. membrane element and prevent concentration polarization.
BRINE VELOCITY
e brine velocity, or ow, over the membrane surface is very important
to both product water quality and quantity. At low ows, concentration
polarization occurs, causing the water quality to decline.
In addition to inferior product water quality, low brine ows can
increase the precipitation of sparingly soluble salts. e salts will foul
the R.O. membrane element surface (concentration polarization). If
this occurs, the product water ux (production) will decline.
e feed pump integrated design provides a relatively smooth and continual
ow of feed water across and through the R.O. membrane element.
COMPACTION
Some densication of the membrane structure may take place while operating
at elevated pressures, above 1000 PSI. e change is known as compaction
and is accompanied by a reduction in the water permeation rate.
When the R.O. membrane element is subjected to elevated pressures
beyond 1000 PSI, the product water channel becomes squeezed,
resulting in restriction and product water recovery reduction.
OSMOTIC PRESSURE
e transfer of the water from one side of the membrane to the other will
continue until the head (pressure) is great enough to prevent any net transfer
of the solvent (water) to the more concentrated (feed water) solution.
At equilibrium, the quantity of water passing in either direction is equal,
and the head pressure is then dened as the "osmotic pressure" of the
solution having that particular concentration of dissolved solids.
Following terms are helpful in becoming familiar with
a FCI Watermakers Reverse Osmosis System.
GLOSSARY OF TERMS

FCI WATERMAKERS, INC. 6FCI WATERMAKERS, INC. General
PRESSURE
e operating pressure has a direct eect on product water quality and quantity.
Both factors will increase as the system pressure increases (within design limits).
e system must be operated at the lowest pressure required to achieve
the designed product water ow rate. is parameter also minimizes
compaction, which occurs faster at higher pressures and temperatures.
At low temperatures or high salinity feed water, the system will have to operate at
higher than normal pressure to maintain the specied amount of product water
ow. is is normal and is due to the design characteristics of the system.
SPIRALWOUND MEMBRANE
e spiral‑wound membrane consists of multiple membrane envelopes, each
formed by enclosing a channelized product water carrying material between two
large at membrane sheets. e membrane envelope is sealed on three edges with
a special adhesive and attached with the adhesive to a small diameter pipe.
A polypropylene screen is used to form the feed water channel between the membrane
envelopes. A wrap is applied to the membrane element to maintain the cylindrical
conguration. e center tube is also the permeate (product water) collecting channel.
Several elements may be connected in series within single pressure vessel
or multiple pressure vessels.
WATER TEMPERATURE EFFECT
e product water ow through the membrane is signicantly aected
by the water temperature. At any given pressure, this ow increases with
increasing water temperature and is reduced at lower temperatures. e system
pressure will need to be adjusted to maintain a precise amount of product
water ow. For systems with APC, this adjustment will be automatic.

Your FCI Reverse Osmosis Desalination System is designed to provide lasting
performance using high‑grade materials and uncompromising engineering. FCI
systems utilize high‑grade alloys in critical components, where competing brands oen
use inferior material that compromise system operation and jeopardize the vessel.
NEW SYSTEM PERFORMANCE
Although each system has been fully tested prior to shipping, there will be a
break‑in period. During this period, approximately 48 hours, the pumps and
membrane performance will change or settle. Small adjustments will need to
be made to the high‑pressure valve. e water quality and quantity will vary.
For a typical installation, the high‑pressure valve will need to be increased
(turned clockwise) and the water quality produced will improve over this
break‑in period. For systems with APC, this adjustment will be automatic.
FCI watermakers are the most advanced desalinating systems
available, which produce potable water from seawater or brackish
water. For over a twenty years, FCI Watermakers, Inc. has pioneered
technology and innovated features that have become standards
for today’s desalinators: one-touch commands, multiple station
operation and remote system control and monitoring, touchscreen
displays, and automated pressure control. As both engineers
and crasmen, we specialize in high-performance, value-driven
watermakers and are proud of the thousands of continuously
operating units that have been cruising the globe for decades.
GENERAL INFORMATION

FCI WATERMAKERS, INC. 17
FCI WATERMAKERS, INC. General
SEMIPERMEABLE MEMBRANES
Reverse Osmosis Membranes are a spiral wound ltration system using alternating
semipermeable and permeable materials to process and separate the product uid from
the concentrate solution. eir ltration capabilities and application are dependent
on several factors: chemical composition of the uid to be ltered, properties of the
semipermeable material required due to this composition, uid temperature, operating
pressure, total dissolved solids to be removed, as well as several other small factors.
e lter size or permeate ow rates are determined as a function of the square foot of
semipermeable material used in the membrane, as well as the factors described above.
e typical rejection rate of reverse osmosis lters is 90 to 99.9 percent of Sodium
Chloride, as well as many other impurities. is constitutes an excellent utilization of
available water resources for large scale water purication requirements. Filter sizes for
both commercial and residential applications generally range from 2" X 12" to 8" X 40".
ese sizes will meet almost all applications in today’s water purication industry.
TYPICAL MEMBRANE ELEMENT
e typical membrane element has the following properties:
• Semipermeable Materials
• in Film Composite (TFC)
• Chlorine sensitive, chlorine must be removed up stream of the membrane
• Bacteria resistant
• pH range is 3.0 to 11.0
• Highest water production rate of all reverse osmosis membranes
THEORY OF OPERATION (continued)

FCI WATERMAKERS, INC. 18Pre-Installation
2/ PREINSTALLATION
e FCI Watermakers system is supplied with an installation kit which
includes an assortment of hoses needed to install the system. Because of the
various options with regard to location, voltage and optional accessories, wire

Do not over tighten PVC ttings. If threaded pipe ttings leak aer installation,
remove the tting, clean the mating threads, apply 3 to 4 wraps of Teon tape to
the male threads, apply liquid Teon pipe sealer sparingly, and thread the parts
back together. PVC ttings should only be hand tightened without the use of a
wrench. e sea cock valve, in-line pressure gauge (if equipped), sea strainer,
rinse-clean inlet valve (if equipped), and low pressure pump should be installed
at or below water level. is will aid the low pressure pump in priming.
Always allow hoses and tubes to enter and exit straight from the
connection for a minimum of one inch prior to a bend. If stress is placed
on the tting due to a tight bend the tting will leak and may break.

contact, ush repeatedly with water and notify a physician immediately.
R.O. membrane elements are stored in “sodium bisulte.”
NEVER mount liquid-holding component above any electrical or
electronic device. Extensive damage to the electronic device will result if
liquid enters device during maintenance and or component failure.
CONNECTION LINE CAUTIONS— All connection lines
should be as short and straight as possible using minimum
ttings. e connection lines must not be “kinked.”
ACCESSIBILITY CAUTIONS— is is a simple rule: Install the system
and its supporting components in an accessible manner. e electrical control
display or panel must be accessible for operation and monitoring of the system.
ELECTRICAL POWER REQUIREMENTS— Ensure that
the power source is suciently sized to provide the correct voltage
and cycles during start up and operation. If unsure, please consult
with your local installation specialist or qualied electrician.
