Isotherm SFD00012AA – Water Mixing Valve Kit for Slim-A (Pre-2004) and Slim Square Models

The Isotherm SFD00012AA is an OEM thermostatic water-mixing valve kit designed for Isotemp Slim-A water heaters built before 2004 as well as Slim Square models. This thermostatic assembly blends hot and cold water to maintain a stable output temperature, protecting users from scalding and ensuring consistent performance across the vessel’s hot-water distribution system. It restores correct temperature regulation in older and retrofitted installations where original mixing components may have degraded over time.

Built from marine-grade corrosion-resistant materials, the mixing valve is engineered for durability under continuous exposure to hot water, fluctuating pressure, vibration and marine humidity. Its thermostatic cartridge automatically modulates the blended temperature and reduces thermal stress on the heater and downstream plumbing. The kit serves as a direct OEM replacement and is typically installed during maintenance, system upgrades or refurbishment of legacy Slim-A and Slim Square water heaters.
