Hot Spring Freshwater III Ozone System Complete Kit — Corona Discharge Replacement for 1995+ Spas, High-Output

Hot Spring Freshwater III Ozone System Complete (item 72602) is a compact, high‑output corona discharge ozonator designed to reduce foaming and refresh hot tub water for compatible Hot Spring, Tiger River and Limelight models.

If you own a compatible Hot Spring spa and want clearer, fresher‑smelling water with lower reliance on sanitizer, the Freshwater III offers a direct replacement that upgrades ozone output and longevity compared with many ultraviolet units. The kit arrives ready to install with the ozonator, injector, ozone‑resistant tubing and a check valve, plus a direct‑connect power cord. Designed for 1995 and newer models, it balances simple DIY installation with professional performance in small‑footprint housings.

How does the Freshwater III reduce foam and improve water smell?

The Freshwater III uses a corona discharge (CD) method to generate ozone, producing a higher concentration of ozone gas per minute than many UV style ozonators. Ozone acts on organic contaminants and oils that cause foaming and odors, breaking them down so filters and sanitizers can remove the residue more effectively.

• Corona discharge generation for elevated ozone concentration (higher PPM).
• Targets oils, lotions and organic debris that lead to foam and unpleasant scents.
• Works alongside your existing chemical routine and filtration system.
• Produces fine ozone bubbles that give spa water a fresh "rain" aroma.

Will the Freshwater III fit my spa and how long does installation take?

This replacement unit is compatible with Hot Spring, Tiger River and Limelight spas manufactured from 1995 to present. It arrives as a complete kit to simplify swapping in the new ozonator, and most owners can finish installation in under an hour with basic tools.

• Compatible with 1995‑forward Hot Spring, Tiger River and Limelight models.
• Includes injector, tubing, check valve and direct‑connect power cord for straightforward replacement.
• Estimated installation time: about 45 minutes for a standard swap‑out.
• Low power draw: 8 watts, 0.21 amps—minimal electrical load on spa systems.

What makes this ozonator different from ultraviolet alternatives?

Unlike ultraviolet ozone generators that use UV light to convert oxygen, the Freshwater III uses corona discharge to create ozone at a higher and more stable concentration. That means peak ozone output remains effective over years of use rather than gradually declining as some UV bulbs lose intensity.

• Corona discharge method yields higher initial ozone concentration and long‑term consistency.
• Designed to maintain performance without the frequent output drop associated with some UV bulbs.
• Compact design fits into existing spa equipment bays with a direct power connection.
• Produces visible fine bubbles that enhance water circulation and distribution of ozone.

What comes in the complete Freshwater III kit and what are the specs?

The complete replacement kit (item 72602) contains everything needed to replace older ozonators and start producing higher levels of ozone right away. The system is engineered for low electrical consumption and practical service life in typical residential spa environments.

• Package includes: Freshwater III CD ozonator, injector, ozone‑resistant tubing and check valve, and direct‑connect power cord.
• Item number: 72602—matched for Hot Spring replacement parts ordering.
• Power consumption: 8 watts, 0.21 amp draw—energy efficient operation.
• Installation is straightforward; keep manufacturer guidelines for plumbing and electrical steps.

Who is this for? The Hot Spring Freshwater III Complete Ozone System is intended for spa owners who want an easy, effective replacement ozonator that improves foam control and water freshness without overhauling their chemical routine. It suits DIY installers or service technicians caring for Hot Spring, Tiger River or Limelight models manufactured from 1995 onward, particularly those seeking a compact, long‑lasting corona discharge solution that maintains higher ozone output over time.
