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.

Introduction to the system
The large control box contains the:
 Spectra Connect control panel
 Main circuit breaker for the system
 The Run Manual, Run Auto and Service
switch.
 Start and stop buttons for manual operation
The small control box is for the feed/boost pump
and includes;
 Auto (run) and Manual switch
 Off (down), Auto run (middle), Manual start is
up (spring loaded)
 See the speed control manual (from the man-
ufacturer) for more detailed instructions
The main valve panel for each LB-10,000 watermaker is identical and all the valves
and gauges are clearly labeled.
The system contains both pressure transducers (for the Spectra Connect controller)
and pressure switches for operation in manual mode.
Note that all the valves in this picture are in the off position. There is an arrow on the
yellow handle that shows the direction of flow. To open the valve turn the arrow in the
direction you want the water to flow to (or from).
For example the inlet/
service valve needs to
point down to run the sys-
tem so water will flow from
the pre-filters.

Both of the watermakers are identical and are capable of fully automatic operation or can be
run manually. In manual mode the system is still protected from loss of feed pressure and ex-
cess membrane pressure, which are the two main things that can cause a fault.
Note that the valves (yellow handles) are shown in the off position.

Introduction to the system
Feed/boost pumps
The two Boost pumps pressurize water from
the feed tank connected to the container.
There is a basket strainer on each pump that
can be checked through the clear window on
the top of the unit.
Note that these pumps must be full of water
before starting. Running these pumps dry will
damage the unit very quickly. The pump
speed is controlled by the small control box
below the main control.
See the boost pump manufacturers manual in
the binder for more detail.
Chlorine Injection
There are two Chlorine Injectors (one for each
system) that add chlorine when the unit is mak-
ing product water (the injection pump is powered
when the diversion valve is open. The manufac-
turers operation manual is in the binder.
Media filters
Each system has two media filters connected
in parallel. Pressurized water from the Boost
Pump is pushed into the media filters and
then on to the cartridge filters.
The pressure gauges on the end of the mani-
folds show the pressure in and out of each
media filter pair. Note what the normal pres-
sure drop is after the filters are back-flushed
and monitor the pressure difference (pressure
drop) across the filters. Back flush the filters
when the pressure drop is 3-5psi.
See the media filter manufacturers manual in the binder for more detailed instructions.

Introduction to the system
Cartridge Pre-Filters
Each system uses two 4x20” 5 micron filters as the final
stage of filtration before going to the Pearson Pump and
the seawater membranes.
There is a button on top of each housing to bleed air out
of the housing after changing filters. There are pressure
gauges on both the inlet and outlet to monitor pressure
drop across the filters. When the pressure drop across
the filters is 5 to 10psi (maximum) the filters should be
replaced.
Test Ports
There are product water test ports for each system so
the operator can confirm the produce quality. Note
that measuring the chlorine concentration should be
measured from the product tank as the chlorine injec-
tion point is too close to the sampling valve for ade-
quate mixing.
The black ABS Drain Manifold is the drain for the
brine discharge and the back-wash from media filters.
This manifold is open (vented) at the top and it should
be noted that if the drain line outside the watermaker
is too small or is not graded properly that this vent pipe
may need to be extended through the top of the con-
tainer.
Carbon Block Filters
Product water from the storage tank needs to be pres-
surized and connects to the “Flush Water” port on the
outside of the container. The flush water goes through
Carbon block filters for removing chlorine from the
flush water to protect the membranes.

11
Introduction to the system
Input / Output Manifold
The ports that allow the plumbing connections to go in and out of the container are lo-
cated at the floor level.
The bottom two ports are feed water to the boost pumps.
The next two are chlorinated product water out to the storage tank (on the left) and
pressurized chlorinated water back from the storage tank.
The top connection is the drain that is connected to the brine discharge from both wa-
termakers and the back-flush drain from all four media filters.
A wash down hose is connected to unchlorinated product water (after the charcoal fil-
ter to use for rinsing after filter changes and filling the chlorine injectors with water.

INSTALLATION
Recommended Site Layout
It is always preferable to draw feed water from a Borehole or Beach Well. Drawing
water directly from the open ocean creates additional maintenance requirements, as
pipes, pumps and the filtration system are exposed to sea life. All of this is avoided by
using the local geology as a barrier to sea life. The feed water from a Borehole or
Beach Well will typically run quite clear after the system has been running for a few
days.
Feed water is moved and pressurized by either a Jet Pump or a Well Pump depend-
ing on site specific conditions. If the system cannot be installed close to the feed water
source, the Jet Pumps provided with the system can be relocated closer to the water
source. Jet Pumps are more efficient when placed close to the feed water source and
will self-prime up to 10ft. (3m). The pipe runs for each of the two systems should be at
least 1-1/2” up to 50 ft. (15m) and be increased to 2” (or more) f it needs to be longer.
Please consult our application engineers to select the correct pump and pipe diame-
ters for your installation.
If the feed water has high turbidity (cloudy water) a Settling Tank may be a good addi-
tion to the installation. A Settling tank is also useful if the feed water intake varies due
to tides or other site specific constraints.
The input and output connections to the Container are outlined on the next page.
The Product Water Tank should ideally be sized to so there is enough storage to sup-
ply water for at least 24 hours to allow for service and maintenance. Water going to
the product tank will be chlorinated by the chlorine injection system in the Container.
The Potable Water Delivery System (by others) needs to provide pressurized water
20-50 psi (1.5 to 3.5 bar) to the Fresh Water Flush Connection on the container.

14
Site requirements for container
The container weighs a little under 20,000 lbs (9090 kg.) and should be mounted on a concrete pad in accord-
ance with local regulations.
The ideal installation has a gentle slope that allows water drain out the door and drain holes. The far end of
the container needs to be elevated 5-6” (130-155mm) from flat. With the container sloped toward the door
from the far end, the right side (when standing at the door end) of the container needs to be 1-1/2 to 2” higher
than the left side.
Note that there is also a catch basin on the container floor around the feed pumps and the cartridge filters so
that water will drain out under the input/output manifold plate built into the left side of the container. Allow for
drainage at the door and under the input/output manifold with a gravel catch basin.
Pipe connections:
The drain for the brine discharge is 2”
NPT (pipe thread) and should be sloping
away from the container if at all possible.
With both units running the flow through
the drain will be 28 gpm (106 lpm), so if
the drain is not sloped correctly the vent
pipe inside the container may need to be
extended.
Feed water from settling tank is 1-1/2”
NPT (pipe thread) and it is recommended
that this connection is made with flexible
hose. If relying on the feed pumps in the
unit be sure the lowest level in the feed
tank is no more than 10ft (3m) below the
floor of the container.
INSTALLATION, continued...

15
The Fresh Water Flush is a 1” NPT (pipe thread) fitting.
Connect the pressurized fresh water supply from the
potable water delivery system to this connection. The
potable water system must supply 5 gpm (20lpm) of po-
table water at 30psi (2 Bar) to fresh water flush the sys-
tems.
The Product Water Outlet is a 1” NPT (pipe thread).
Route the product water pipe from the container to the
top of the storage tank. Ideally the product water
should fall into the tank so there is no back pressure on
the product line. Do not feed the water into a manifold
or bottom of the tank and make sure there is no re-
striction in this plumbing. Backpressure on the prod-
uct water line can cause membrane damage.
The top of the water tank must be no more than 10
feet (3M) above the top of the desalinators frame
and if you need the unit to pump water over 10 ft.
install a transfer tank and a delivery pump.
It is not recommended to use the desalinator as a prod-
uct water delivery pump. If the product water must be delivered up hill or to a tank more than 50
feet/15M away and/or more than 10feet/3m up run it to a transfer tank and use a separate pump to
move water to the desired location.
Electrical
Connect the main in-
coming power feed to
the AC main discon-
nect panel.
Connect all wires in
accordance with local
regulations.
Wire should be sized
for 30Amp max current
draw at 220VAC.
Note: The photo above shows the temporary wiring we used for testing the unit. Follow all local codes
and best practices when making the connections to the power source on site.
All internal wiring is complete to the main distribution panel, with separate circuits that are clearly la-
beled. All equipment should be in the off position when applying power for the first time.
INSTALLATION, continued...

16
Optional 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
The Terminal Block for the tank level switches is on the
right side of the control box .
The control system is designed to shut down when the
tank switches close. When tank is full, both switches
must be closed.
Note: If tank switches are not used you must disable the
tank switches in the system settings.
Tank Level Sensor
Installing a tank level sensor (KIT-SC-TNKSS) in the discharge line from your storage
tank will allow the Spectra Connect to track the tank level. Once the sensor is installed
connect to the Terminal Block above referring to the wiring diagram for terminal loca-
tion.
Tank Switch Installation

The optional Tank Level sensor allows even greater control of your fresh water storage
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 freshwater supply pump, 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.

Route the 3 conductor cable back to the Spectra Connect control box and extend the
wires as necessary. If you must extend the wires beyond 50’ contact the factory to en-
sure proper operation.
Connect the Tank Level Sensor cables to the appropriate terminals in the control board
inside the main Control Box (pg. 14) and refer to the wiring diagram on pg.54 to identi-
fy 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. 22) in the “New System Start-Up” 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. Any pressure drop will ef-
fect the tank level sensor accuracy.

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.
 Confirm there is oil in the crankcase
(check the dip-stick)
 Pressure Relief Valve is OPEN one full turn
Use this procedure when the system contains preservative or cleaning chemi-
cals.
Warning! Damage will occur if the system is not purged of the storage chemicals
before pressurizing the system.
Maintenance note; Get into the habit of recording the pressures and
flow rates of the system in the Log Book. Knowing what is normal
for this installation is one of the best tools you will have to keep the
system running properly.
Initial power-up
When power is first applied to the unit the
main breaker (Emergency Shut-Off)
should be in the off position. The Run
toggle switch should be in the AUTO po-
sition.
