2. Impostazione
Proper setup is crucial for the performance and longevity of your Intex PureSpa. Ensure you have a flat, stable surface for placement. The spa should not be placed on grass as it can damage the grass and potentially the spa liner over time. A concrete patio or a dedicated spa pad is recommended.
2.1 Disimballaggio e posizionamento
- Rimuovere con attenzione tutti i componenti dalla confezione.
- Lay out the thermal ground cloth (included) on your chosen flat surface. This provides insulation and protection for the spa's base.
- Position the deflated spa on the ground cloth.
2.2 Inflazione
The PureSpa features a self-inflation system integrated into the control unit.
- Collegare il tubo di gonfiaggio dall'unità di controllo alla valvola di gonfiaggio della spa.
- Turn on the control unit and activate the inflation function (usually indicated by a bubble icon).
- Inflate the spa until it is firm to the touch but not overinflated. The walls should be rigid enough to sit on.
- Inflate the insulated cover using the same method.

2.3 Collegamento dell'unità di controllo
- Connect the three hoses from the spa to the corresponding ports on the control unit. Ensure all connections are hand-tight to prevent leaks.
- Plug the control unit into a grounded electrical outlet. The unit is designed for 120V operation.
3. Operating the Spa
The intuitive control panel allows for easy management of your spa's functions.

3.1 Riempimento della Spa
- Fill the spa with fresh water using a garden hose. Fill to the indicated maximum water level line on the interior of the spa. The water capacity is approximately 290 gallons.

- The heating system typically raises the water temperature by 1-2°F (0.5-1°C) per hour. It may take several hours to reach the desired temperature, especially during initial setup.
- Keep the insulated cover on while heating to minimize heat loss.
3.3 Attivazione dei getti di bolle
- Press the bubble jet button on the control panel to activate the 170 high-powered bubble jets.

- Clean the filter cartridges daily by rinsing them with a garden hose.
- Replace cartridges every 1-2 weeks, or more frequently with heavy use, to maintain optimal filtration.
4.2 Trattamento dell'acqua
- The built-in hard water treatment system makes water gentler on skin.
- Regularly test water chemistry using a 3-way test strip (included) and adjust chemical levels as needed (e.g., chlorine, pH, alkalinity).
- Use a floating pool chlorine dispenser for continuous sanitation.
4.3 Pulizia e conservazione
- Svuotare completamente la spa prima di pulirla o di riporla per un lungo periodo.
- Clean the interior and exterior surfaces with a mild soap and water solution.
- Ensure the spa is completely dry before folding and storing it in the provided carry bag.
- Do not leave the spa outside below 39°F (4°C).

5.1 Leaks and Punctures
The spa is made from puncture-resistant 3-ply laminated material. In the event of a small leak or puncture, a repair patch kit is typically included. Follow the instructions in the kit for proper application. Ensure the area is clean and dry before applying the patch.
5.2 E90 Error
An E90 error code usually indicates a circulation issue, often related to clogged filters. Clean or replace the filter cartridges and ensure proper water flow through the control unit.
