Thank you for your purchase of a Spectra Catalina 340c system. When properly installed and
maintained, it will provide years of trouble free service. Professional installaon is strongly
recommended. Like any piece of mechanical equipment, the system will require inspecon
and service, so plan ahead for service access and install “service loops” in cabling. If a dealer is
installing the system for you, review the locaon of the components to ensure the installaon
will meet your approval upon compleon.
Catalina Installaon Quick Start
Important Details for Installer
1. The system must have a dedicated sea water inlet to guarantee a constant ow of water to
the system. The inlet should be as low in the boat as possible with a dedicated, forward-facing
scoop-type thru-hull ng.
2. Both the Catalina 340c feed pump module and the Clark Pump/Membrane module must be
installed in a well venlated compartment where temperatures will not exceed 113°F (45°C).
Many engine compartments exceed this temperature when underway. Warranty will be void if
the installaon does not meet this requirement.
3. Follow the wire gauge charts in the instrucons! Using larger wire than specied is
acceptable.
4. If you are separang the Clark Pump/membrane assembly, please review the high pressure
tube assembly instrucons. Improper assembly will cause failure!
5. Run, test, then sea trial the complete system before assuming it is operaonal. If the boat is
in fresh or dirty water, see Dry Tesng the System. Aer tesng, make sure the ush cycle
operates properly. The water going overboard at the end of the ush should measure <1000
PPM Total Dissolved Solids.
6. The Spectra Connect control must have DC power connuously to achieve the full benets
of the fresh water ush system. The domesc fresh water pressure must be on and the fresh
water tank level maintained. Calculate about 7 gallons (27 liters) per ush.
7. The Spectra Connect control must be de-powered (DC power o) aer the system is pickled
or winterized.
8. Spectra dealers are responsible for educang the vessel owners on the operaon and
maintenance of the system. Please walk through the enre installaon with our customer.
9. The equipment owner should ll out the warranty card or register online.

Installaon Basics
• Read the direcons!
• Avoid ght hose bends and excessive runs.
• Use heavy gauge wire.
• Install feed pump module as low as possible.
• Boost pump module must be installed below the waterline.
• Use a dedicated thru-hull with scoop-type strainer.
• Do not mount components over electrical devices.
• Avoid geng dirt or debris into the piping or hoses during
assembly. A small bit of debris can stop the system!
Thru-hull Locaon: The system must be connected to a dedicated 3/4” to 1” forward-facing
scoop-type intake thru-hull and seacock.
Install the thru-hull intake as far below the waterline and as close to centerline as possible to
avoid contaminaon and air entering the system. Do not install the intake close to, or
downstream of, a head discharge, behind the keel, stabilizer ns, or other underwater xtures.
Thru-hulls in the bow area are suscepble to air intake in rough condions. Sharing a thru-hull
can introduce unforeseen problems such as intermient ow restricons, air bubbles,
contaminants, and will void the warranty. For racing boats and high speed boats traveling above
15 knots, a retractable snorkel-type thru-hull ng is preferred because it picks up water away
from the hull.
The brine discharge thru-hull should be mounted above the waterline, along or just above the
boot stripe, to minimize water li and back pressure.
Double clamp all hose connecons below the waterline.
Avoid restricons or long runs on the enre inlet side of the plumbing from the thru-hull to the
feed pump module.
Secure the piping away from moving objects such as engine belts and hatches. Prevent chafe on
the tubing as required. Test and inspect all piping and hose clamps aer several hours of
operaon.
Pipe Fing Instrucons: To seal plasc-to-plasc ngs, wrap 6 to 8 layers of Teon tape over
their threads. Hold the ng in your le hand and ghtly wrap the threads clockwise. For
smoother assembly, do not tape the rst (starng) threads.

Components
Feed Pump Module
Mount the feed pump module on a vercal surface, up to 3-
feet (1.0M) above the waterline. It is preferable to mount as
low as possible. Locate in an area that allows easy access to
both the lters, and the le hand side of the enclosure. Keep
future maintenance in mind when choosing a locaon, and do
not mount above water-sensive equipment. The feed pump
has overheat protecon and will not operate properly at
ambient temperatures over 113°F (48°C).
Sea Strainer and Boost Pump Module: Mount close to the
intake through-hull, below the waterline, in a locaon that
can handle water spillage during service. The boost pump
power cable will connect to the feed pump module.
Fresh Water Flush Module: The fresh water ush module
may be located in any convenient locaon near the feed
pump module. It should be mounted with the lter housing
vercal and accessible, with 2” below the housing for lter
changes. Do not install over electrical equipment. The unit
contains the charcoal lter, a solenoid shut o valve, and a
ush water ow regulator.

Double rubber mounts
to absorb vibraon
This module must be installed in an area that maintains a temperature below 113°F (45°C). It
may be placed as high in the boat as you desire, and mounted in any posion, even upside
down. Make sure that the area around and under the pump does not have any water sensive
equipment, as water will be spilled during any repairs or if a leak occurs. Allow for easy access
to the pressure relief valve.
The Clark pump and membrane module comes complete with a mounng system. Be sure to
use the supplied washers on the rubber feet.

Plumbing Detail
Your system includes 25-feet of 1/2-inch vinyl hose with a Quick
Connect ng on one end and a 1/2-inch John Guest stem
ng on the other, both crimped on with ferrules. You will CUT
THIS HOSE and, using the ngs found in the installaon kit,
use one end for the feed water inlet hose and the other for
the fresh water ush hose:
Fresh Water Flush: Route a feed line from the domesc cold pressure water system to the
1/2-inch hose barb on the fresh water ush module. This needs to be pressurized when the
boat is unaended for the fresh water ush system to funcon properly. The domesc fresh
water pump must be able to deliver 1.5 gallons per minute (6 LPM) at 25 PSI (1.7 bar).

Product to tank: Route the product water into the top
of a vented tank, or a tee in the water tank ll hose.
DO NOT feed into a vent line, manifold, or into the
boom of the tank. Bladder tanks will create too much
back pressure. There must be no restricon or back
pressure whatsoever in this piping.
Salinity Probe (under)
Diversion Valve
The 1/4”(6mm) product water tubing is pre-plumbed from the membrane into the electric diversion
valve. The diversion valve will reject product water into the overboard brine stream unl the
Connect controller determines the product water is below 750 PPM salinity. Once below 750 PPM,
the Connect controller opens the diversion valve and product water is diverted into the fresh water
tank. The salinity probe must be mounted in a vercal posion with the cable coming out the
boom. If the Clark Pump/Membrane Module is mounted vercally or upside down the diversion
valve/probe assembly MUST be remounted in the proper orientaon.

Factory Supplied Tank Full Switch
Installing the supplied tank full oat switch at the top of your water tank
allows the Spectra Connect to ll your water tank then automacally stop,
fresh water ush and return to Auto Store mode with no addional user
commands.
Note: The oat may need to be ipped 180 degrees to work properly. The
oat can be easily ipped by removing the clip opposite the wire.
Drill and tap a 1/8” npt port into the top of the fresh water tank that is being lled by the
watermaker. This can be installed on a tank access cover, or directly into the water tank. If
installing on an access cover, be sure to leave a service loop on the oat switch wiring to allow
removal of the tank access cover.
For Instrucons on ‘Auto Fill’ mode and installing a Tank Low switch, see ‘Auto Fill’ mode
instrucons later in this manual.
Watermakers should never be run unaended.
Your watermaker comes with the top-mounted Tank Full Switch (EL-SWT-LV) and is designed
to be mounted to the top of the water tank. The side-mounted oat switch (EL-SWT-SMLV)
can be sourced from your local dealer or Full Service Provider if you cannot access the top of
your tank.
If you do not install the Tank Full switch in your tank, you MUST DISABLE the Tank Full
Switch in the system sengs. See System Sengs instrucons later in this manual.
