This tank is designed specifically for AIR-O-SWISS humidifier models 7133 and 7135. Please read this manual thoroughly before use to ensure optimal performance and longevity of your humidifier.
Setup and Installation
This section details the steps for installing your new replacement water tank onto your AIR-O-SWISS Ultrasonic Humidifier base.
Unpacking the Water Tank
Carefully remove the water tank from its packaging. Inspect the tank for any visible damage. If damage is present, do not use the tank and contact customer support.
Filling the Water Tank
- Remove the water tank from the humidifier base, if it is currently attached.
- Turn the water tank upside down. Locate and unscrew the tank cap.
- Fill the tank with clean, cool tap water. Avoid using hot water or adding any additives (e.g., essential oils, medication) directly into the water tank, as this may damage the humidifier.
- Securely screw the tank cap back into place. Ensure it is tightened to prevent leaks.
Placing the Water Tank on the Base
- Ensure the humidifier base is clean and free of debris.
- Carefully place the filled water tank onto the humidifier base. The tank should sit firmly and level on the base.
- Once placed, water will begin to flow from the tank into the base reservoir. This is a normal process.
