752721-100 American Standard Multi Speed Control System

Reclaim the soothing power of your whirlpool with the 752721-100 American Standard Multi Speed Control System—a modern replacement designed to fit your tub without patching or invasive renovations. This carefully engineered upgrade delivers smoother, more reliable control, easier installation, and flexible operation that adapts to a variety of setups.

What’s included:

• 1× 120V 8.5A Variable Speed Pump — robust performance, engineered as a seamless stand-in for ITT MARLOW and other brush motor pumps.
• 1× 120V Control Box (VSPC) — compact, easy to install, and designed to fit beneath most tub configurations.
• 1× Waterproof Floating Remote Control — batteries included, with High, Medium, Low speeds, On/Off, and a convenient 30-minute timer.
• Free union included for convenient piping connections.

Key features that matter:

• Variable speed operation — switch between High, Medium, and Low to tailor jet intensity and ambiance to any mood or room layout.
• Remote with battery included — cordless control from anywhere around the tub, plus a built-in 30-minute timer to help manage energy use and comfort.
• Compact, installer-friendly design — pump base is designed for stability and the control box mounts under the tub, often without any plumbing changes.
• Compatibility and reliability — a dependable replacement for ITT MARLOW brush motor pumps and other similar units, delivering consistent whirlpool performance.

How it works — Power runs on a standard 120V circuit to the variable speed pump, delivering smooth, adjustable jet action. The floating remote communicates wirelessly with the control box, enabling quick speed changes and the built-in 30-minute timer for automated shutoff. If you prefer, you can keep your existing keypad in place—the kit is designed to coexist with current setups, minimizing renovation work.

Installation & compatibility — designed for straightforward installation; in most cases no plumbing modifications are required. The pump base must be replaced with a stable platform to reduce vibrations, and the old base will not fit the new pump. Requires a dedicated GFCI-protected circuit for safety, and 120V operation is essential (if your tub is 240V, conversion to 120V is necessary for this kit to work). A free union is included to simplify piping connections and future maintenance.

Why choose this replacement — enjoy precise, quiet, and dependable jet control with flexible integration options. This modern system brings intuitive wireless control, a practical 30-minute timer for energy efficiency, and a compact footprint that simplifies installation. It’s not just a swap—it’s a transformative upgrade to your hydrotherapy experience.
