Therma-Kleen Electric Steam Cleaner

Frequently Asked Questions
Use distilled, softened, or bottled water. This is crucial for preventing mineral buildup (limescale) in the boiler and on the heating element, which can shorten the machine's life and is not covered under the warranty. Tap water should only be used as a last resort.
Always use cold water when filling the water tank or connecting to the water inlet. The machine is designed to heat the water to the specified high temperatures.
Heating time varies by model. For units like some vapor models, it can take around 8-13 minutes, or up to 25 minutes to reach optimal temperature (around 330°F).
No, only water should be put into the main water tank or boiler. Adding chemicals can damage the internal components and void the warranty. On certain high-pressure models like the Ultra series, an external chemical injection system might be available as an option, but harsh chemicals should still be avoided in the internal system.
This is normal during start-up. Excess condensation in the system needs to bleed out before the steady, dry steam appears. This usually lasts only a few seconds. Also, ensure you have waited for the machine to fully heat up and build pressure before using the trigger gun.
The most critical maintenance is to flush the boiler regularly to remove mineral deposits. This should be done every other week or more frequently if using hard tap water. Also, always empty the machine completely of all water after each use and before storing to prevent damage from freezing.
