R150VS19C Gemini Plus Pump Replacement System

Revitalize your spa with the R150VS19C Gemini Plus Pump Replacement System—a modern, energy-conscious upgrade built to replace the aging Gemini Plus setup. This kit delivers precise control, streamlined installation, and a more enjoyable spa experience without the guesswork.

Key to a better spa is how you control water flow and massage intensity. The R150VS19C puts you in command with 20/20 precision: a variable-speed pump lets you dial in High, Medium, and Low settings to match your spa size, mood, and energy priorities. Say goodbye to overshooting your desired massage and hello to exactly the comfort you want, every time.

What makes this upgrade stand out

• Variable-speed sophistication—The new 8.5 amp, 120V pump provides seamless transitions between speeds, so you can tailor the flow for a deep-tissue soak or a gentler warm-up.
• Dynamic massage modes—In addition to standard speeds, Wave and Pulse modes deliver resort-style massage patterns for deeper relief or soothing relaxation as you prefer.
• Compact, integrated control—The CG AIR SYSTEMS Control Box 115 is designed to tuck neatly under most tub setups, keeping the area tidy and accessible for service if needed.
• Intuitive keypad design—A 2.5" white square keypad fits a square 2.5" faceplate, with a clean surround for a finished look that’s easy to operate from behind the tub rim.
• Plug-and-play plumbing—Includes a free union to connect to your existing plumbing with no extra purchases required, simplifying the swap-out process.
• Stable, quiet operation—Plan a solid base for the new pump (the new base is not reused from the old unit) to minimize vibration and noise from day one.
• Electrical safety first—Connect to a dedicated, GFCI-protected circuit for reliable, safe operation around water.

What’s included in the Gemini Plus Pump Replacement Kit

• New 120V 8.5 amp Variable-Speed Pump compatible with existing plumbing
• CG AIR SYSTEMS Control Box 115, engineered for variable-speed operation
• Variable-Speed Keypad in White (fits a 2.5" square opening)
• Free union for seamless connection to current plumbing
• Installation and setup guidance to streamline the upgrade

Installation and compatibility at a glance

• 120V operation—This kit is designed for 120V use to simplify wiring and setup. If your spa runs on 240V, a power-source conversion is required for proper operation.
• Fits your existing plumbing—The kit is designed to align with your current plumbing layout, making the swap straightforward and minimizing downtime.
• Under-tub compatibility—Compact control box is easy to tuck away, preserving space around the tub and making servicing convenient.
• Stable base required—A sturdy base protects against vibration and ensures long-term reliability; plan this during setup.

Why this upgrade matters for your spa

Longevity and reliability: Replacing obsolete Gemini Plus components with a modern variable-speed system and a robust control box restores consistent performance and can extend the life of your spa. Energy efficiency is not just a buzzword here—precise speed control means you use only the water flow you truly need, cutting unnecessary energy consumption while maintaining your preferred massage experience.

Ideal for

• Home spa owners updating an aging Gemini Plus system
• Customers seeking more consistent massaging action and energy efficiency
• Anyone wanting a compact, tidy control solution that’s easy to access for maintenance
• DIY-friendly installations where plumbing is already configured for 1-1/4" connections with a free union

Before you power up, ensure the spa is wired to a dedicated GFCI circuit and that the base is solid to minimize vibration. If you’re upgrading a 240V setup, plan the necessary power-source conversion in advance. With the Wave and Pulse modes, try pairing a higher speed with intermittent pulses for a revitalizing full-body massage, then ease back to Low for a relaxing wind-down.
