Operating your Supertub
See the following sections for more details on how to operate your Supertub and how to navigate the UI.

Via the Permafrost™ chiller display

1. Temperature display
Displays the current temperature of the water in Celsius or Fahrenheit. To switch between Celsius and Fahrenheit, press the "Settings" icon on the bottom left of the main display interface, and toggle the °C or °F icon at the top right of the settings interface.

2. Temperature slider
Set your desired water temperature by tapping the and icons, or dragging the temperature slider to the right or left.



3. Switch icon
Tap to turn on or switch off the water flow between the chiller and the Supertub.

To turn on water flow between the chiller and the Supertub, you will need to both turn on the power switch at the back of the chiller, and tap the Switch icon.

It is possible to set your chiller to auto-power mode, which turns on water flow once the power switch at the back of the chiller is switched on. To turn on auto-power mode, press the "Settings" icon on the bottom left of the main display interface, and toggle the “Power on” icon at the top left of the settings interface.

However, we do not recommend turning on auto-power mode, as that increases the likelihood of user errors such as accidentally turning on the water flow when there is not enough water in the chiller or when the water valves are closed, which may cause damage to the chiller.



4. Fault warning icon
Appears if there is an issue with your Permafrost™ chiller. If the Fault Warning icon appears, tap it to view more information. The error message should include steps to troubleshoot the issue.

If you are unable to fix the issue on your own, contact Customer Support (support@hydragun.com) for help.

Tips for beginners
1. Start slow
• We recommend starting at a higher temperature (e.g. 50°F (10°C)), and gradually lowering the temperature over several sessions as your body gets used to the cold.

• The water should feel uncomfortably but not painfully cold in each session. We also recommend starting with less frequent sessions (e.g. 2-4 times a week) and gradually increasing them as you become comfortable with the routine.

• Finally, we recommend starting with shorter sessions (e.g. 1-2 minutes) and increasing to up to 5 minutes as you become comfortable.

While using the Supertub, pay attention to how your body is responding to each session, and make sure you are using the right temperature settings and session durations for you. If you feel any unexpected pain or discomfort during a session, stop use immediately and consult your physician.

2. Breathe
Focus on taking slow, deep breaths. Your body might react to the cold with short, shallow breaths, so it’s important to slow down and focus on your breathing.

3. Warm back up naturally
After you exit the Supertub, dry off with a towel and let your body warm back up naturally to experience the full benefits of cold water immersion therapy.

When to use your Supertub
Use your Supertub for a maximum of one time daily to:
• Boost physical recovery after high-intensity exercise
• Increase energy and focus for many hours after use
• Build mental fortitude and grit
• Enhance your mood
• Speed up metabolism
