Therma-Kleen Steam Cleaner

Frequently Asked Questions
It is highly recommended to use distilled, softened, or bottled water. This prevents mineral deposits (limescale) from building up in the boiler and internal components, which is a common cause of performance issues and is not covered under warranty.
Always use cold water when filling the tank. The machine is designed to heat the water to the proper temperature. Using hot water (above 140°F) can damage the pump and other components.
No, only water should be put into the main water tank or boiler. Adding other substances can damage the machine, create a safety hazard, and void the warranty. On certain models with an optional external injection system, chemicals can be used outside the main water flow.
The machine is ready when the temperature gauge reads the optimal temperature (e.g., around 330°F), and on electric models, the red heater indicator light goes out.
This indicates a low water level in the reservoir or boiler. Turn off the heater switch, release remaining steam, and carefully refill the tank with cold water.
Regularly flushing the boiler to remove mineral deposits is critical. This should be done every other week or more often depending on water hardness. Always completely empty all water from the unit after each use and before storage to prevent damage from freezing temperatures.
