Impact is a crucial step in ensuring water quality and proper functioning of the luxury spa hot tub. The impact time is generally 10–20 minutes, which can be extended to 30 minutes for larger water volumes or complex systems. Frequency is recommended once a week or after each use, depending on the actual situation.

• If you plan to use your luxury spa hot tub during the winter, ensure it's insulated enough to operate safely in cold temperatures. • If you plan to leave it unused for the entire winter, drain it thoroughly, clean it, and seal it tightly to prevent any residual water from freezing.
