Objective

This step-by-step guide will walk you through testing your sauna with the LED wires unplugged from the HUUM Main Module.

This test helps determine whether the LED system is causing the house breaker to trip. A breaker trip could be due to:

• A short in the LED wiring
• The customer using a GFCI breaker, which may not be compatible

By testing the sauna without the LED connected, we can identify if the LED is the source of the issue.

Tools Required

• Philips screwdriver
• T25 Bit (Mini Model only)
• Flathead screwdriver

Step-by-Step Instructions

1. Power Down the Sauna

• Unplug the sauna power cord from the power receptacle.

⚠️ Important: Never attempt to modify wiring while the sauna is plugged in. Ensure the power cord is fully unplugged before proceeding.

2. Remove the Electrical Box Cover

XL & Standard Models:

• Use a Philips screwdriver to remove the cover mounted on the outside of the heater panel.

2. Using a flathead screwdriver, loosen the terminal screws securing the LED wires.
3. Carefully remove the LED wires from the terminals.
4. Ensure that no exposed wires are touching other connections in the module.

5. Restore Power & Test the Sauna

1. Replace the HUUM Main Module cover and secure it with screws.
2. Do NOT reconnect the LED wires yet.
3. Plug the sauna power cord back into the power receptacle.
