Objective

To ensure proper sauna functionality, it is critical to follow the correct electrical specifications when preparing your installation space. This guide provides all necessary electrical details for your electrician to set up power correctly.

⚠️ Important: Failure to meet these requirements can lead to reduced performance, slower heating times, and increased wear on electrical components, which may not be covered under warranty.

Voltage Requirements

📌 The HUUM Main Module is rated for 240V.

• If the sauna receives 208V instead of 240V, the heater will lose 50% of its power output.
• To ensure the sauna heats efficiently and effectively, the voltage at the sauna when the heater is on should be no lower than 230V.

✅ What happens if voltage is too low?
If the voltage at the sauna drops below 220V when the heater is on, you may experience:

1. Restricted maximum temperatures – The heater may struggle to reach higher heat settings.
2. Slower heating times – The sauna will take longer to warm up.
3. Increased electrical wear – Low voltage increases amperage, which can prematurely wear out electrical components and heating elements.

🚨 Warranty Notice:
Failures caused by low voltage (below the required specifications) will not be covered under warranty. Ensure your electrician properly measures and confirms voltage at the sauna while the heater is on.

Electrical Specifications by Sauna Model

📌 The power cord does not come with the sauna and must be purchased separately.

• We offer a 10ft power cord as an add-on item for purchase.
• Power cords longer than 25 feet are not recommended, as they can cause voltage drops that reduce sauna performance.
• Ensure your electrician installs the outlet within 25 feet of the sauna to prevent voltage issues.

Installation Recommendations

• Hire a licensed electrician to install the outlet on a dedicated circuit that meets these electrical specifications.
• Verify that the voltage at the sauna meets the requirements when the heater is running.
• Ensure the power outlet is positioned within 25 feet of the sauna to prevent voltage drop.
• If you do not already have a power cord, purchase the correct sauna power cord before installation to avoid delays.
• Share this article with your electrician to avoid setup issues and ensure compliance with electrical requirements.
