What is the maximum timer duration recommended for spas located a minimum of 6 feet horizontally?

The recommended maximum timer duration of 15 minutes for spas located at least 6 feet horizontally addresses safety and health considerations. This duration allows for adequate use of the spa while also minimizing risks associated with prolonged exposure to heated water. Spas often operate at higher temperatures than regular swimming pools, which can elevate the risk of hyperthermia if individuals stay in for extended periods. By establishing a timer maximum of 15 minutes, it encourages users to take breaks for cooling down and allows them to monitor their exposure to the heat effectively. This duration strikes a balance between user enjoyment and the prevention of health hazards, making it a crucial guideline for safe spa operation.
