Safety Information
WARNING: Keep away from naked flame or direct heat sources.
- Always supervise children in and around the spa.
- Do not use electrical appliances near the spa.
- Consult a physician before use if you have health conditions.
- Ensure the spa is placed on a flat, stable surface capable of supporting its weight when filled.
Setup Guide
1. Site Selection
Choose a suitable location for your spa. The area must be flat, level, and free of sharp objects. Ensure adequate drainage is available. The spa dimensions are 216 x 216 x 71 cm and it weighs approximately 46.4 kg when empty, significantly more when filled with water and occupants.
2. Inflation
The PureSpa™ features a FastFill Inflation System for quick and easy setup. Connect the inflation hose from the control unit to the spa's inflation valve. Use the touch button control panel to activate the inflation function.

3. Water Filling
Once inflated, fill the spa with water to the recommended level, typically indicated by a fill line inside the spa. Ensure the drain valve is securely closed before filling.
4. Initial Heating
After filling, activate the heater using the control panel. The spa can heat water to a range of 20-40° Celsius. Note that initial heating may take several hours depending on the ambient temperature and water volume.
Operating Instructions
Control Panel
The PureSpa™ features an intuitive touch button control panel. This panel allows you to activate the bubble massage, adjust temperature, and manage filtration.

Bubble Massage Function

Hard Water Treatment System
The built-in Hard Water Treatment System makes water gentler on skin and helps prevent calcium buildup, which can limit water flow and reduce the spa's lifespan. This system operates automatically to maintain water quality.

Maintenance
Water Quality and Filtration
Regular maintenance of water quality is crucial for the longevity of your spa and user health. This includes regular cleaning of the filter cartridge and chemical treatment of the water. Refer to the control panel for filter cleaning indicators.

Spa Cover
Always use the included insulated spa cover when the spa is not in use. This Energy-Efficient Spa Cover helps maintain water temperature, reduces energy consumption, and keeps debris out of the spa.

Cleaning and Storage
For long-term storage, ensure the spa is thoroughly cleaned and completely dry before deflating and packing away. This prevents mold and mildew growth and extends the product's life.
Troubleshooting
- Slow Heating: Ensure the spa cover is on when heating. Check ambient temperature; colder conditions will increase heating time. Verify filter is clean.
- Bubbles Not Working: Check power connection. Ensure the bubble function is activated on the control panel.
- Water Quality Issues: Regularly test water chemistry and adjust as needed. Clean or replace filter cartridges frequently. The Hard Water Treatment System helps, but additional chemical treatment may be necessary.
- Display Not Working: Ensure power supply is stable. If the display remains unresponsive, contact customer support.
- Air Leakage: Check all valves and caps are securely tightened. Inspect the spa body for any punctures.
