- Plug in the control box and press the "Bubble" button to begin inflation.
- Inflate until the spa walls are firm to the touch, but not over-inflated. Do not use an air compressor.
- Disconnect the inflation hose and securely close the air valve.

3. Control Box Connection
Connect the control box to the spa body's water inlet and outlet ports. Ensure all connections are tight to prevent leaks.
4. Water Filling
Fill the spa with fresh water using a garden hose. Fill to the recommended water level indicated on the spa's interior wall. Do not overfill.
5. Filter Installation
Install the filter cartridge(s) into the filter housing(s) inside the spa. Ensure they are securely twisted into place.
Operating Instructions
1. Control Panel and MSpa Mobile App
The spa can be controlled via the integrated control panel on the external unit or through the MSpa mobile application. The app provides full control over spa functions from your smartphone.

2. Heating Function
Press the "Heater" button on the control panel or app to activate the heating system. The water temperature will increase at a rate of approximately 1.8-2°F per hour, up to a maximum of 104°F (40°C). The display will show the current water temperature.
3. Bubble Massage System
Activate the 138 Air Jets Massage System by pressing the "Bubble" button. The system offers 3 variable bubble speeds for a customized experience. Press the button repeatedly to cycle through speeds or turn off.
4. Smart Filtration
The smart filtration system automatically runs to keep your water clean. Ensure filter cartridges are regularly cleaned or replaced for optimal performance.
5. Anti-Icing System
The anti-icing system automatically activates when the water temperature drops below a certain threshold, preventing freezing and protecting internal components. This feature is designed for use in cold weather conditions.
6. Heating Timer
Utilize the heating timer function to schedule when the spa heater turns on. This allows you to pre-heat the spa to your desired temperature before use, saving energy and ensuring it's ready when you are.
Maintenance
1. Water Chemistry
Regularly test and adjust the spa water chemistry (pH, alkalinity, sanitizer levels) according to recommended guidelines. Improper water balance can damage the spa and cause skin irritation.
2. Filter Cleaning and Replacement
Clean filter cartridges weekly by rinsing them with a garden hose. Replace cartridges every 1-2 months, or more frequently with heavy use, to maintain efficient filtration.
3. Draining and Cleaning
Drain and refill the spa water at least once every two months. When draining, clean the interior surface of the spa with a soft cloth and mild, non-abrasive cleaner. Rinse thoroughly before refilling.
4. Spa Cover Care
Always use the spa cover when the spa is not in use. The included energy-efficient cover significantly improves heat retention, saving up to 50% on energy. Clean covers regularly with a mild soap and water solution. Inspect for damage and repair as needed.
