5.2 Initial Heating
After filling, press the 'Heat' button. The spa will begin heating the water to your set temperature. This process can take 12-24 hours depending on ambient temperature and initial water temperature. Keep the spa covered during heating to minimize heat loss.

6. Maintenance
6.1 Water Chemistry
Regularly test and adjust your spa water chemistry. Maintain pH levels between 7.4 and 7.6, and ensure proper sanitizer levels (e.g., chlorine or bromine) to prevent bacterial growth. Use the included chemical dispenser for even distribution.
6.2 Filter Cartridge Cleaning and Replacement
Clean the filter cartridges weekly by rinsing them with a garden hose. Replace cartridges every 2-4 weeks, or more frequently with heavy use, to ensure efficient filtration.
6.3 Draining and Cleaning
Drain and clean your spa every 1-3 months, or as needed. Connect a garden hose to the drain valve, open the valve, and allow the water to empty. Clean the interior surfaces with a mild, non-abrasive cleaner and rinse thoroughly.
6.4 Storage
For long-term storage, ensure the spa is completely drained, cleaned, and dry. Deflate the spa and store it in a dry, temperate location, away from direct sunlight and extreme temperatures.
