How to inspect the ELB (Earth Leakage Breaker)?

Step 1: Press the ELB button.
Step 2: The ELB Reset Lever should slide down and the current supply is actively cut off. Step 3: Push up the ELB Reset Lever. The ELB indicator LED will light up, indicating the set is ON.

How often should I check if my ELB is working?

Regularly checking the ELB once a month is important to protect users and avoid potential harm, including property damage, severe injury, or death.

Is it dangerous not to turn off the main switch after showering?

The main switch controls the Live line of the internal circuit. For safety, especially if the ELB fails and there's an issue with the electricity supply, turning off the main switch is crucial. It ensures that no electricity flows through the product, preventing any electrical hazard risk.

How do I clean a blocked showerhead?

Use a soft brush to clean the holes on the Shower Head. It is recommended to clean weekly.
