What precaution should be taken when deliming boilers or steamers that use floats?

When deliming boilers or steamers that use floats, removing the floats before adding chemicals is essential to ensure safety and proper function. The floats are usually made of materials that could be sensitive to harsh chemicals used in the deliming process. Adding chemicals with floats still installed may lead to damage of the float mechanism, which can affect the operation of the boiler or steamer.

Additionally, if the floats are in place, the chemicals might not reach all necessary areas for effective cleaning, potentially leaving scale deposits inside the unit. By removing the floats, the chemicals can work more effectively on the surfaces needing treatment, leading to optimal cleaning results and maintaining the equipment's efficiency and longevity.
