Please read through the complete manual before starting your installation. The sys-
tem is easy to operate and maintain as long as it is installed and calibrated correctly.
Spectra Watermakers Land Based Desalination Systems are shipped pre-tested and
pickled with propylene glycol for shipment. The system is ready for installation with the
options specified with your order. Please unpack the system and inspect it to make
sure that it has not been damaged in shipment.
Refer to the shipping list for your system to make sure you have received all of the
components listed.
We will not be held responsible for shortages that are not reported within thirty
days of the ship date. Shipping damage must be reported to the carrier within
24 hours of receiving goods.
Ensure that there is proper clearance around the system for removal of filters and sys-
tem service. We recommend that there is at least 36” in front of the control panel (to
allow for removal of membranes) and 24” on both sides of the watermaker.

Fresh Water Flush
Pressing the ‘Fresh Water Flush’ button
flushes the watermaker with fresh water
from the vessel’s domestic water tanks.
After completing the flush, Spectra Con-
nect will automatically enter the Auto Store
mode.
Stop
Pressing the ‘Stop’ button from the Home
Screen will end the Auto Store mode
countdown timer and leave your watermak-
er in Standby mode.
When you first power up the system, you will get a warning message, asking if the sys-
tem has been stored with chemicals.
If the system has been pickled, winterized, this is the first startup, or the condition
of the system is unknown, go to COMMISSIONING or serious damage may occur.
Start
Pressing the ‘Start’ button once advances
to the Run Mode selection screen.
Spectra Connect Quick Start Guide
Run Mode
Select your desired Run Mode to start mak-
ing water and filling your tanks. See details
on Run Mode options on p. 37
Spectra Connect Modes and Definitions
Auto Store: After the watermaker fresh water flushes, it will start a countdown timer that
can be seen on the Home screen. The timer indicates the next programmed fresh water
flush if the watermaker is not started again, or the ‘Stop’ button is not pressed.
Fill Tank: The watermaker will automatically run until the Tank Full switch in the water
storage tanks closes. Once the Tank Full switch closes, the watermaker automatically
fresh water flushes, then reverts to the Auto Store mode.
Auto Run: The watermaker can be set to run for a number of hours, or for a quantity of
water to be produced. When the desired quantity of water is produced or the run timer
expires, the watermaker will Fresh Water Flush and enter the Auto Store mode.

Product Water tubing
The Product Water Outlet is a 3/4” hose barb x 3/4” female pipe thread fitting. Route the prod-
uct water tube from the product water outlet fitting on the front of the unit into the top of the stor-
age tank. Ideally the product water should fall into the tank so there is no back pressure on the
product line. Install a tee in the water tank fill or tap a pipe thread into an inspection port in the
top of the tank. Do not feed the water into a manifold or bottom of the tank. Make sure there is
no restriction in this plumbing. The top of the water tank must be no more than 10 feet (3M)
above the top of the watermaker frame.
The limit on the system pumping product water is the back pressure created on the mem-
brane when the system shuts down. If you need the unit to pump water over 10 ft. install
a good quality check valve (with low cracking pressure) in the product line as this will
eliminate back pressure on the membrane (from the product) when the system shuts
down. Pressurized product water running back into the system can cause membrane
failure.
A product sampling tap can be installed along the tank fill hose between the outlet and the tank
connection. If a 3-way valve is used as sampling tap or filling manifold is to be installed on the
product water line, then an “open-before-close” type 3 way valve should be used to ensure that
the product water line is never accidentally pressurized.
It is not recommended to use the watermaker as a product water delivery pump. If the product
water must be delivered up hill or to a tank more than 50 feet/15M away, run it to a transfer tank
and use a separate pump to move water to the desired location.

INSTALLATION
The LB series watermakers must be protected from direct sun and weather. UV from
the sun will degrade the hoses, tubes and fittings used in the system. It is recommend-
ed that the unit be under a roof in a permeant enclosure with good ventilation and drain-
age.

8
Feed Water Inlet
Feed water must be supplied to the feed water in-
let at a minimum pressure of 20psi (1.3bar) and a
Minimum Available Flow Rate of 6.5gpm
(24.5lpm). Silt density must be less than 3 SDI.
If the water supply has a lot of silt in it a settling
tank and or media filters are recommended.
Brine Discharge
Feed Water Inlet
Note that the brine discharge must go to
an open drain with an air gap so there
is no suction possible.
Route the Brine discharge from the cam lock fitting
back to the feed water source, or to another eco-
logically acceptable location. The brine flow will
be roughly 4.5gpm (17 pm) and will be saltier than
the feed water.
Inlet valve
The system requires a regulated inlet pressure of
20 to 30 psi on the Boost Pressure gauge. It is
recommended that the feed pressure be set as
high as possible with new filters and the pump not
knocking.
Optional Pressure Regulator
The picture at right shows the feed water solenoid
valve and the optional pressure regulator assem-
bly.
Note; If there is no water flowing the pressure reg-
ulator may be set too high so unscrew the adjuster
all the way and then adjust the feed pressure as
water is flowing. Adjust the pressure regulator
with a 3/8” Allan wrench so the boost pressure
shown on regulator gauge is 20 to 30 psi.
INSTALLATION

9
Control Box Electrical Cables
All connections to the control box are clearly
labeled next to the corresponding connector.
Be sure to use a properly sized circuit breaker
between the equipment and the power source.
Use a length of SO cable to connect to the
power source. All units use 24v DC for the
control circuits and a power supply is included
in the box (on AC units).

INSTALLATION Control System Overview
Main Breaker
Service Switch
Connecting the Spectra Connect control
board to an Ethernet Switch or a LAN port on
your wireless router will allow the system to be
controlled from any mobile device.
Initial power-up
When power is first applied to the unit the main
breaker (Emergency Shut-Off) should be in the off
position. The Service toggle switch should be in
the off position.
The Run toggle switch on the speed control
should be in the Auto position for both the main
pump and the optional boost pump.
Note this is Three way Toggle Switch:
Up—AUTO
Middle—OFF
Down—Manual

11
INSTALLATION Control System Overview
VFD Speed controls
The VFD for the Pearson Pump is
mounted for easy access. This
speed control is configured for the
line voltage indicated on your order
and it converts this to 3 phase output
which allows for speed control.
It also provides “soft start” so the
motors will not draw more than their
normal full load.
Systems supplied with the optional
boost pump will use the same speed
control which can be connected to
the water maker (via the attached
control cable) so it will start when the
watermaker starts, or it can be oper-
ated independently.
In normal operation the toggle switch
should be in the AUTO position.
Three way Toggle Switch:
Up—AUTO
Middle—OFF
Down—Manual

Factory Supplied Tank Switches
There are two types of tank float switches available depending on your installation re-
quirements. Often making an assembly as pictured below (right) is a good solution as
there is only a single penetration and it can be above the high water level.
Top mounted float switch EL-SWT-LV
Side mounted float switch EL-SWT-SMLV
Refer to the wiring diagrams for the Terminal Block
numbers for the tank level switches.
Note: If tank switches are not used you must disable
the tank full switch in the system settings.
Tank Level Sensor
Installing a tank level sensor (EL-SSR-5PSI) in the discharge line from your storage
tank will allow the Spectra Connect to track the tank level. See the next page for de-
tailed installation instructions.
Tank Switch or Level Sensor Installation

13
The optional Tank Level sensor allows even greater control of your ship’s fresh water
systems. This unique level monitoring system requires no holes to be drilled into your
tank while measuring tank volume with greater accuracy than a standard resistive float.
Turn off the ship’s domestic water system, close the fresh water supply valve at the
water tank, then bleed off the pressure by opening a tap in the galley or head sink.
Install a tee in the water supply hose at the bottom of the tank, or at the inlet to
the domestic water pump. Connect open leg of the tee to the Tank Level Sensor.
Note: The tank level sensor requires a 1/4” npt connection. We recommend installing
a minimum 1/2” tee, and using a reducing bushing to connect the sensor.

Pump
Route the 3 conductor cable back to the Spectra Connect control board at the feed
pump module. Extend the wires as necessary. If you must extend the wires beyond
50’ contact the factory to ensure proper operation.
Connect the Tank Level Sensor cables to the appropriate terminals in the Control
Junction Box (pg. 10) and refer to the wiring diagram on pg.49 to identify the correct
terminals . Polarity must be maintained!
If a 2nd Tank Level Sensor is going to be installed, it should be installed at the base of
the second tank. If monitoring 2 connected water tanks, they must be isolated
from each other with a valve to read properly.
The wiring connections for the second Tank Level Sensor are located inside the Spec-
tra Connect control box. See System Settings section of this manual for instruc-
tions on enabling the second Tank Level Sensor.
See the Tank Level Calibration (pg. 17) in the Commissioning section of this
manual.
Optional Tank Level Sensor Installation
Note: Be sure the pipe between the tank and the tank lev-
el sensor is large enough to eliminate pressure drop when
the product pump is running.

New System Start-Up and Testing
1. First Check that:
• Brine discharge is directed to a suitable location. The
brine discharge will contain a small amount of
propylene glycol (non-toxic potable anti-freeze)
during the purge cycle.
• The tape is removed from the oil vent cap on the
top of the crankcase, confirm there is oil in the
crankcase.
• Pressure Relief Valve is OPEN one full turn.
2. Feed flow and pressure gauges
The feed flow gauge will show feed water flowing on
start-up. The Product flow gauge will not show flow
until the flush tank if full.
At start-up the feed water solenoid will open and
Boost Pressure gauge will show the feed pressure
after the filters.
3. Confirm the inlet valve is in the RUN position.
4. Confirm the service toggle switch on
the front panel is in the off position
and toggle switch on the speed con-
trol is in the auto position
5. Turn on the power to the system and the Spectra Connect screen will display, “Has
the system been stored with chemicals?” Press ‘Yes’, to start the Purge sequence.
Note: The watermaker will shut down if the pressure relief valve is left closed during
the Purge mode.
Use this procedure when the system contains preservative or cleaning chemicals.
Warning! Damage will occur if the system is not purged of the stor-
age chemicals before pressurizing the system.

15
6. The system will start purging and the display
will show the progress and time remaining
for the purge cycle.
7. Note that the Filter Pressure gauge is after the electric feed
valve so it will only read feed pressure when the system has
been started (so the feed valve opens and shows the feed
(boost) pressure, which should be about 20 psi during opera-
tion.
If the optional boost pump was included the pressure can be
adjusted with the knob on the boost pump control box.
8. Using the buttons on top of the filter housings, bleed out the air in
the filter housings until water is coming out.
9. Check the brine discharge for water flow. The system
should fully prime within 60-90 seconds and all air
should be out of the feed water hoses. The pump will
should sound smooth and if there is any knocking ad-
just the feed pressure up or down until the pump is
running smoothly. Note if the boost pressure drops
below 10 psi, the system will alarm and tell you to check the pre-filters.
Note: If you must stop the purge sequence for any reason, the control will de-
fault back to the beginning of the purge cycle to protect your system.
New System Start-Up and Testing continued...

10.After the purge sequence the display will
alarm with the message “Close pressure
relief valve.” Close the valve and proceed
by pressing Ok to resume the Purge Cycle
running pressurized and purging the prod-
uct water to drain.
11. The system will now run under pres-
sure and desalinate water. This mode
diverts the product water overboard in
case there is any residual chemicals in
the membrane. Carefully inspect for
leaks over the entire system! Shut
down the system and repair any leaks
you find.
12. After the Product Purge cycle completes, the system will prompt to Restart, then
advance to the Main Menu. If this is a NEW INSTALLATION, continue to the Cali-
bration Instructions to finalize the installation. If you are putting your watermaker
back into service after storage or cleaning your system is now ready for use.
If the system is stored with Propylene Glycol, additional purging time may be re-
quired if there is chemical odor to the product water, or if salinity remains high
after the purge sequence. All systems are shipped from the factory stored with
Propylene Glycol.
Note that the flush tank will fill first and then product water will be diverted to your stor-
age tank.

3. When the Calibration Sequence is com-
plete, press the button in the upper left
corner to return to the Main Menu.
When prompted by the display, Click Save
to make sure that the Calibration is stored
in the system memory.
4. The Filter Condition gauge has now been
calibrated to match your installation.
1. During the calibration sequence the system will automatically start, begin to make
water for several minutes and then shut itself down. Make sure that new filters are
in place before proceeding.
2. Follow the steps in Figures 1—4 below to initiate the Calibration Sequence.
Sensor Calibration
Many of the settings on your system have been pre-calibrated during standard factory
testing, however, there are a few settings that will vary based on the installation condi-
tions. If the system has just been installed you must calibrate the Pre-filter Con-
dition graph before proceeding.
This procedure does not need to be done with each filter change under normal opera-
tion, it should ONLY BE DONE IF THE FILTER CONDITION GAUGE WON’T RESET
TO 100% WITH NEW FILTERS.
