4.2 Inflation
- Connect the inflation hose from the control unit to the spa's inflation valve.
- Press the inflation button on the control panel. The spa will inflate automatically.
- Once fully inflated (approximately 5 minutes), disconnect the hose and securely close the valve.
- Inflate the energy-efficient spa cover using the same method.
4.3 Connecting the Control Unit
Connect the three hoses from the spa to the corresponding ports on the control unit. Ensure all connections are hand-tightened only to prevent damage and ensure a watertight seal. Do not use tools for tightening.
4.4 Filling the Spa
Fill the spa with water using a garden hose until the water level is between the minimum and maximum fill lines indicated on the spa's interior. This typically takes 1 to 1.5 hours.
5. Operating the Spa
5.1 Control Panel Overview

The control panel features a digital display and various buttons for easy operation:
- Power Button: Turns the spa on/off.
- Temperature Adjustment Buttons (Up/Down Arrows): Adjust the desired water temperature (68-104°F / 20-40°C).
- Heater Button (Flame Icon): Activates the heating system. The PTC heater will maintain the set temperature.
- Bubble Massage Button (Bubbles Icon): Activates the 120 high-powered bubble jets.
- Filter Button (Filter Icon): Controls the water filtration cycle (e.g., 2, 4, 6 hours, or off).
- Celsius/Fahrenheit Button (C/F Icon): Switches between temperature units.
5.2 Heating the Water
After filling the spa, ensure the energy-efficient cover is in place to minimize heat loss. Press the Heater Button on the control panel and set your desired temperature. The spa will gradually heat the water. Heating time varies based on ambient temperature and initial water temperature, typically taking 12-24 hours to reach maximum temperature from cold fill.

5.3 Using the Bubble Massage
Press the Bubble Massage Button to activate the 120 air jets. Note that using the bubble massage feature, especially in colder temperatures, may cause a slight decrease in water temperature as it pulls in ambient air.
6. Maintenance
6.1 Water Chemistry and Treatment
Regularly test your spa water using test strips to ensure proper chemical balance. The built-in Hard Water Treatment System helps reduce calcium buildup, but additional chemical treatment may be necessary. Refer to the included spa water chemistry and balance charts for guidance on adjusting pH, alkalinity, and hardness.

6.2 Filter Cartridge Care
The spa uses a filter cartridge to keep the water clean. Regularly clean and replace the filter cartridge as recommended in the full user manual to maintain optimal water quality and pump efficiency.
6.3 Energy Efficient Cover
Always use the energy-efficient spa cover when the spa is not in use. This cover significantly reduces heat loss and helps maintain water temperature, leading to energy savings.

7. Troubleshooting
7.1 Common Issues
- E90 Error Code: This error often indicates a flow issue or a problem with the heating element. Ensure the filter cartridge is clean and properly installed, and check for any obstructions in the water circulation system. Consult the full user manual for detailed E90 troubleshooting steps.
- Water Not Heating: Verify the heater button is activated and the desired temperature is set. Ensure the spa cover is securely in place. Check the filter for clogs.
- Bubbles Not Working: Ensure the bubble massage button is pressed and the air blower is functioning. Check for any blockages in the air jet system.
