Modules are arranged here for identification; their installed positions vary. The supplied CAD shows selected components. Internal seals and other service items may appear in the parts list without separate 3D geometry.

Parts identified in the supplied CAD

Match the installed connections to the modeled arrangement. The 3/4-inch hose fittings below are CAD-size matches; later Deluxe plumbing can use 5/8-inch hose. These links do not expand the model finder’s compatibility list.

Modeled componentPart or referenceWhat to check
Prefilter elbows · 3/4-inch hosePL-HBE-3/4X3/4Two 90-degree fittings connect the prefilter housing to the hose. Each is named 3/4-inch NPT × 3/4-inch hose barb in the supplied CAD. The supplied CAD uses a 3/4-inch hose barb here. Check your installed hose inside diameter: later Deluxe plumbing can use 5/8-inch hose. Match both ends before ordering. Manufacturer reference ↗
Flush-filter elbows · 3/4-inch hosePL-HBE-3/4X3/4These are the two separate hose elbows at the carbon-filter assembly. The CAD name supplies the 3/4-inch male pipe thread and 3/4-inch hose barb; the geometry shows the elbow shape. The supplied CAD uses a 3/4-inch hose barb here. Check your installed hose inside diameter: later Deluxe plumbing can use 5/8-inch hose. Match both ends before ordering. Manufacturer reference ↗
Intake straight fitting · 3/4-inch hosePL-HBS-3/4X3/4Straight fitting at the intake service-valve connection: 3/4-inch NPT to 3/4-inch hose barb in the original CAD. The supplied CAD uses a 3/4-inch hose barb here. Check your installed hose inside diameter: later Deluxe plumbing can use 5/8-inch hose. Match both ends before ordering. Manufacturer reference ↗
Clark Pump hose elbow · 5/8-inch hosePL-HBE-3/8X5/8The CAD identifies this Clark Pump connection as a 3/8-inch NPT × 5/8-inch hose-barb elbow. The older Ventura Deluxe parts drawing names PL-HBE-3/8X5/8 at the pump. Check the installed port and brine-hose arrangement when replacing an older module. Manufacturer reference ↗
Brine hose · complete pigtail optionSUB-CT-Z-HPILHAThe selected piece is the short brine hose. SUB-CT-Z-HPILHA is the documented complete Clark Pump pigtail assembly, with end connections, rather than a bulk-hose SKU. Compare the installed ends with the drawing before replacing the assembly. The separate threaded mating body is identified as PL-QDC-BD3/8. Manufacturer reference ↗
Membrane-support bracket end capsFM-PVB-PBE (manufacturer reference)These two shaped mounting caps bridge the membrane-support base. Spectra identifies the plate-bracket end cap as FM-PVB-PBE. They are outside the pressure vessel and are different from the pressure-vessel end plugs. Reference identification only; this SKU has no listing in the supplied store catalog. Manufacturer reference ↗
High-pressure module plate bracketFM-PVB-PB (manufacturer reference)This is the larger support base with raised membrane saddles. The manufacturer drawing identifies the plate bracket as FM-PVB-PB. It is separate from the small flat mounting plate directly beneath the Clark Pump. Reference identification only; this SKU has no listing in the supplied store catalog. Manufacturer reference ↗
Ventura feed-pump mounting bracketFM-VT-ITM (manufacturer reference)The folded sheet-metal chassis supports the feed pump and service controls. Spectra calls this Ventura feed-pump bracket FM-VT-ITM. This label identifies the bracket; it does not include the pump, filter or separately modeled fasteners. Reference identification only; this SKU has no listing in the supplied store catalog.

HP-TB-ARP

Annular ring

Two annular rings sit inside the valve block around the reversing spool. The four annular-ring O-rings are separate items.

Drawing · page 54 ↗
KIT-HP-10VSA

Reversing spool assembly

The Deluxe drawing labels this assembly KIT-HP-10VSA; the 2024 rebuild sheet uses KIT-HP-VS10 for 7%/10%. These reference labels are not treated as a verified replacement chain or mapped to a bare spool listing.

SUB-MTS-3/8X1/2

Cylinder tube fitting

The Deluxe drawing calls this stainless; the current store record with this exact code says bronze. The 2024 rebuild sheet specifies PL-MTS-3/8X1/2S. No purchase link is assigned until the installed material and revision are verified.

Drawing · page 56 ↗
HD-CPS-5/16X3

Valve-block mounting bolt

The drawing identifies four longer bolts joining the valve block to the center block. Dimensions are omitted because the Deluxe annotation and SKU differ.

HD-CPS-5/162.75

End-block bolt

The rebuild sheet shows eight shorter bolts for the end blocks. The illustration does not specify installation torque.

Match the mounting bracket

Spectra labels these mounting parts in the Deluxe drawings. Compare the installed bracket shape and mounting-hole arrangement with the drawing.

  • FM-VT-ITM — Ventura feed-pump bracket (page 51).
  • FM-PVB-PB — plate bracket (page 50).
  • FM-PVB-PBE — plate-bracket end cap (page 50).

A plate-bracket end cap is mounting hardware; it is different from the membrane pressure-vessel end plug.

Prepare for storage

Use the storage procedure for your installed preservation equipment. SC-1 is for storage, not membrane cleaning or freeze protection. Follow the manual’s quantities, flushing and return-to-service steps.

SC-1 storage compoundStorage instructions · page 36 ↗
Low output? Check the system before buying a membrane.

The manufacturer calls for a flow test before membrane cleaning. Use its troubleshooting procedure to distinguish feed, pump and membrane issues.

ANSWERS FOR DELUXE OWNERS

Filters, membrane and configuration questions

What size filters does the Ventura 150 Deluxe use?

The documented FT-FTC-5 seawater prefilter and FT-FTC-CC carbon flush cartridge are nominally 10 inches long by 2.5 inches in diameter. Check the cartridge part number as well as its size: these filters serve different water circuits.

Are the carbon filter and seawater prefilter interchangeable?

Use FT-FTC-5 in the documented seawater prefilter stage and FT-FTC-CC in the freshwater flush stage. The carbon element removes chlorine from flush water; the 5-micron prefilter captures particles in the seawater feed.

Which membrane fits the original Ventura 150 Deluxe?

The original short-vessel 150D arrangement uses one KIT-MB-20F membrane. Spectra uses both 20-inch and 21-inch wording for this short kit. Identify it by part number and installed vessel; the separate end plugs and retaining rings are vessel service items.

How do I choose the 12V or 24V feed pump?

Read the voltage on the installed motor label, then select that voltage above. The guide shows KIT-FP-SF12 for the documented 12V configuration or KIT-FP-SF24 for 24V. Check the product's contents and configuration requirements before ordering.

Does this guide cover Ventura MPC or Connect systems?

This page covers Ventura 150 Deluxe configurations. MPC, Connect and other control arrangements have separate finder selections. Check the installed controls and any replaced modules instead of choosing solely by the Ventura name.

Can I identify every internal part in the 3D model?

The manufacturer CAD shows the main assemblies. A separate Clark Pump reconstruction illustrates the exterior and internal service groups from the manual. Its dimensions and fine details are approximate; use the original drawings and product requirements for identification.

References: membrane drawing, page 50; filters and feed pump, page 51. Cartridge dimensions and pump-package requirements are detailed on the linked product pages above.
