Swim spa hot tubs are typically maintained at a temperature of 33°C to 38°C. Warm water initially dilates blood vessels, followed by slight vasoconstriction as the body regulates temperature. This temperature cycle makes the nervous system more active, thus triggering a "wrinkle response."

1. Preparation • Check water temperature • Check pH level • Wear protective equipment 2. Flushing Operation Steps • Calculate dosage • Dissolve the flushing agent evenly • Start the circulation system • Check residual chlorine or bromine concentration 3. Post-Flush Water Treatment • Maintain circulation • Clean the filter • Check and adjust pH level

In fact, the active ingredient in bleach does share the same chemical basis as some chlorine-based disinfectants. Both rely on the bactericidal effect of hypochlorous acid (HOCl). The differences are: • Bleach directly contains sodium hypochlorite solution (highly alkaline, unstable).

• Drainage time: 30 minutes to 3 hours, depending on conditions. • Refilling time: Depends on the water flow rate. Household tap water typically flows at 10-20 liters per minute. If a bathtub has a capacity of 3,000 liters, filling it may take 2-5 hours.

The water level in a luxury swim spa hot tub is not necessarily better the higher it is, nor should it be too low. Generally, when using a luxury swim spa hot tub in a home or private setting, the water level should be controlled at 70%-90% of the total tub depth.

The space required to install a swim spa hot tub depends on its type, size, and usage environment: • Compact: At least approximately 5.5m × 3m; • Standard: Approximately 6.5m × 3.5m; • Large or dual-zone: At least 8m × 4m; • Equipment and maintenance space: It is recommended to add an extra 1m safety margin to the main dimensions.
