Model and membrane arrangement
Look for CT-340RS-12, CT-340RS-24 or CT-340RS-48 on the label or paperwork. The original arrangement has two short membranes. A retrofit can change the vessels and fittings; compare the installed hardware.

Is this your Catalina 340R Compact?
Remote Manual controls
The remote panel has START, STOP and FLUSH controls. A separate monitoring panel displays the mechanical readings. Connect touchscreen and older MPC controls use different electronics; their parts do not become compatible just because they are also Catalina systems.
340 GPD rated output
Spectra rates this configuration at 14 US gallons / 53 liters per hour, or 340 US gallons per day under its stated baseline of 77°F / 25°C and 33,000 PPM feed water. Output changes with conditions and system health. Model fact sheet ↗
SIZE AND ORDER QUANTITY
Choose the membrane by arrangement
KIT-MB-20F
2 elements · 2.5 × 20 inches
The compact arrangement uses two separate short elements. Each KIT-MB-20F kit replaces one membrane and includes replacement seals. Replacing both original elements requires two kits. Spectra uses 20-inch wording in the fact sheet and 21-inch wording in some parts listings; use the kit SKU and actual short vessels. The standard 40-inch kit is a different arrangement.

FOLLOW THE WATER
How the modules work together
1 · Intake and boost pump
The sea strainer catches larger debris before the boost pump supplies the feed module. Strainer screen and strainer seal are distinct service parts. The illustrated boost pump is an 8–24V component; a 48V system uses a regulated accessory circuit.
2 · Feed pump and prefilter
The magnetic-drive pump head supplies the Clark Pump circuit. Its motor and speed controller are separate components. The 5-micron cartridge removes fine particles; compare its housing and plumbing position with the module drawing.
3 · Pressure and membranes
The 10% Clark Pump recovers pressure energy. The membrane arrangement separates fresh product water from the brine stream: two short membranes in this original configuration. The feed pump, Clark Pump and membrane are different assemblies.
4 · Sample and tank
The product-water plumbing includes a sampling/diversion path. Test product water and follow commissioning directions before sending water to the tank. The Remote Manual controller does not provide the same real-time salinity display as Connect. Product-water plumbing ↗
Freshwater flush circuit
The separate carbon cartridge removes chlorine from freshwater used for flushing. It cannot replace the 5-micron seawater prefilter. An installed Z-Ion option changes the flush-bowl assembly.
Compare your installation
Use the Catalina Remote plumbing schematic ↗ for connections and the model-specific module drawings below. Shared or relocated modules and aftermarket housings need an installed-hardware check.
CARTRIDGES, HOUSINGS AND SEALS
What size filters does the Catalina 340R use?
The documented original seawater cartridge is 5 micron, nominal 10 inches long × 2.5 inches in diameter. The freshwater-flush carbon cartridge is also nominal 10 × 2.5 inches. Nominal sizes can differ from measured end-to-end length; media and end seals must also match.
| Position | Cartridge / size | Pictured housing | Seal and wrench |
|---|---|---|---|
| Seawater prefilter | FT-FTC-5 · 5 micron Nominal 10 × 2.5 in | FT-FTH-10L3PCS · three-piece Verify installed pressure duty | SO-FHS-3PCS10 FT-FHW-3PCS |
| Freshwater flush | FT-FTC-CC · carbon Nominal 10 × 2.5 in | FT-FTH-10L3PCS · without Z-Ion Match any modified Z-Ion bowl | SO-FHS-3PCS10 FT-FHW-3PCS |
| Sea strainer | FT-STN-6S · stainless screen 6-inch strainer class | Identify the sea-strainer/boost module | SO-STN-6SS · strainer seal Not a cartridge-housing O-ring |
Match the housing, not just the cartridge size.
Pages 59 and 62 identify the clear three-piece housing; the general prefilter bulletin describes a different pressure-side arrangement. Confirm the installed housing, pressure duty and module revision with Spectra before replacing a housing. A clear low-pressure housing is not an automatic substitute for a black high-pressure housing. Additional 20-micron stages and Big Blue filters are not established by this original single-5-micron drawing.

REMOTE MANUAL CONTROL
Panel, controller and electrical replacements
Remote panel versus control board
KIT-REM-RPNLA is the Remote Manual panel named on page 61. EL-REM-CBA is a conditional control-board link from the reviewed catalog. They are separate assemblies. Confirm the installed panel, board, connector and harness revision with Spectra before ordering. Neither item alone is a documented complete controls conversion.
System voltage versus component voltage
The pictured EL-MTR-1/6D12 motor is a 12V reference. The 48V schematic shows a 48V-to-24V converter, a 12/24V feed-motor circuit and lower-voltage accessory circuits. Do not order a motor or converter from the system input voltage alone. 48V schematic ↗
Tank-full switch and timed flush
The controller supports a timed freshwater flush and tank-full indication when a suitable float switch is installed. The manual describes a customer-supplied switch; it does not establish a Connect tank-sensor kit as a direct Remote Manual replacement. Tank-switch installation ↗ · Panel operation ↗
48V and changed controller assemblies
Confirm electrical replacements and the regulated accessory supply with Spectra. The manufacturer listing and fact sheet also contain conflicting MFD wording; this guide does not establish MFD operation for the Remote Manual controller.

SEE THE MANUFACTURER LAYOUT
Locate the module before choosing a part
Identify the compact two-short-vessel layout
Compare the actual membrane vessels, feed module, flush bowl, sea-strainer/boost module and two remote panels. The fact-sheet dimensions describe modules, not filter-cartridge length.
Open the feed, flush, intake and control drawings
These shared Catalina Remote drawings are identification references. Match any installed revision and voltage differences.
Compact vessel hardware needs its own check.The shared manual’s page 58 depicts a single long vessel. It is not a compact two-short-vessel parts drawing. Confirm compact end plugs, rings, connecting tubes and fittings with Spectra before ordering; those long-vessel links are not inherited into this guide.
Feed module and motor
The drawing labels the magnetic-drive pump head, a 12V motor, speed controller and clear three-piece filter housing. Use the separate wiring for other supply voltages.
Flush bowl with and without Z-Ion
The carbon element is inside the freshwater-flush bowl. Match an installed Z-Ion bowl and controller; the standard housing alone is not an ion-generator upgrade.
Sea strainer and boost pump
Locate the stainless strainer screen and 8–24V boost pump. The page also depicts a separate plastic-screen variant. Match your installed module.
Remote panel, switches and hose connections
Identify the Remote Manual control panel separately from the monitoring/gauge panel. Match the exact fittings and hose ends when replacing a hose assembly.
10% CLARK PUMP SERVICE GROUP
Identify the block, rod and internal seals
The original Catalina Remote assembly uses a 10% Clark Pump. Ratio-specific parts include HP-CB-CB10 center block, HP-CYL-7/8R piston rod and SO-HPP-PR10 rod seals. The shared center-block drawing lists 7%, 10% and 15% seal alternatives; match the actual pump identification.
Reversing-valve group
The upper valve contains the reversing-valve spool, annular rings, seals and distinct A/B end blocks. It is separate from the smaller pilot spool in the center block. Reversing-valve drawing ↗
Center-block group
Locate the pilot spool, pilot pin and check-valve components. The check-valve seat and seat O-ring have similar codes but different functions. Center-block drawing ↗

OPTIONAL EQUIPMENT AND SERVICE PACKAGES
Upgrades are separate from routine replacement parts
Z-Ion system protection
Spectra specifies ZION-AUTO for Remote Manual systems. Identify the installed generation, approved accessory supply and flush module before adding it. Pre-MK2-Z systems may require a separate plug assembly. Confirm the exact package and installation requirements with Spectra before ordering, particularly on 48V systems. Manufacturer selection guidance ↗
Housing or intake changes
A revised housing, added oil/water separator or boost-module replacement must match the actual pressure circuit, ports and supply. The oil/water separator cartridge is an optional filter-stage item; it is not a drop-in replacement for the existing 5-micron cartridge. Optional additional filtration ↗
Cruising and workshop spares
Basic Cruise Kit A and offshore service kit appear in Spectra’s spares list. The 10% distributor rebuild kit serves a different workshop task. Compare kit contents against your planned work and existing supplies. Suggested spares ↗
CARE, STORAGE AND DIAGNOSIS
Choose supplies by the task
Routine filter service
Inspect the seawater prefilter and replace dirty elements. Spectra advises replacement rather than washing dirty cartridges. Inspect and clean the strainer separately. Strainer and prefilter service ↗
Freshwater-flush protection
Replace the carbon cartridge at least every six months, following Spectra’s water-volume limit if reached sooner. Follow the flush procedure for the installed standard bowl or Z-Ion equipment. Carbon-filter service ↗ · Carbon-filter capacity ↗
Low output or poor quality
Check feed voltage, restrictions, feed flow and Clark Pump balance before concluding that a membrane needs replacement. Spectra calls for a flow test before membrane cleaning. Product quality is a separate diagnostic question. Catalina flow test ↗ · Water-quality diagnosis ↗

COMMON BUYING QUESTIONS
Before you choose a replacement
Which membrane kit and how many?
The original CT-340RS arrangement uses two short membranes: KIT-MB-20F. One kit replaces one element; replacing every original element requires 2 kit(s). Check the installed vessels after any retrofit.
Are seawater and carbon filters interchangeable?
No. The 5-micron cartridge is the seawater prefilter. The carbon cartridge removes chlorine from freshwater used for flushing. Both are nominal 10 × 2.5 inches, but the media serve different circuits.
Does every 10-inch housing use the same O-ring?
No. SO-FHS-3PCS10 is tied to the identified three-piece housing. Other housing designs use different seals and wrenches. Identify the body and installed pressure duty before choosing hardware.
Can I use a 12V accessory on a 48V Catalina?
Only through the documented, suitable accessory circuit. The 48V schematic contains voltage conversion; the system input rating does not become the rating of its boost pump, flush valve or controller. Confirm the actual component and supply with Spectra.
Is this a Connect or MPC controller guide?
No. This guide covers Remote Manual control. A similar system name, membrane or Clark Pump does not make Connect or MPC electronics interchangeable. Board/panel links need an installed-revision check.
Can I use the long-vessel drawing for Compact parts?
The shared manual’s long-vessel picture does not establish the two-short-vessel fittings, end plugs or tube lengths. Confirm those exact compact parts with Spectra before ordering.
Is ZION-MAN the option because the controls are “Remote Manual”?
Spectra groups Remote Manual with its automated controls for ZION-AUTO. ZION-MAN is for the analog-control group. Confirm generation, plug, plumbing and accessory supply before selecting a package.
