Note!
To prevent excessively quick scaling of the heating element when used in water, we recommend the following measures:
• Clean the device regularly, if the water hardness is >7°dH.
• Instigate appropriate measures to reduce the calcium content in the water
• Set the controller to a temperature below 60°C.
–
The temperature of the medium can be continuously adjusted using the temperature selector (if fitted).
– Determine the actual temperature of the medium for a selected setting by trial.

To remove deposits between the heating elements, you must first remove the device.
• Lower the water level in the storage tank for the heating elements to be clear for removal.
• Carefully clean the heating elements to ensure that the pipe jackets of the heating elements are not damaged.
• Ensure that the heating elements are not bent during cleaning.
–
Do not use a wire brush for cleaning.
• Replace the device if you are unable to remove deposits without damaging the element.
8.2 Storage
Complete the following steps to store the device:
• Ensure that the storage location for the device is dry and free of dust to avoid corrosion damage during storing.
