Your Therma-Kleen Vapor Steam Cleaner MUST BE PLUGGED INTO A GROUNDED OUTLET, or electrical shock can occur. Check with a certified electrician if there is any doubt that the outlet is grounded. Do not modify the Power Cord/Plug provided with the Therma-Kleen Vapor System. If it will not fit the outlet, have a properly grounded outlet installed by a certified electrician.


If the unit should malfunction or break down, grounding provides a path of least resistance for the electrical current to pass, reducing the risk of electrical shock. All Therma-Kleen units are equipped with a power cord with an equipment grounding conductor and plug. The plug must be inserted into an appropriate outlet which is properly grounded in accordance with national & local electrical codes and ordinances.  

Therma-Kleen® units are designed for use with a normal 110/120-volt circuit and has a grounded cord and plug such as what is illustrated in picture “A”. In no cases should a “2” adaptor (which is illustrated in picture “B”) plug be used to adapt “3” prong grounded plug to an ungrounded electrical outlet.


If an electrical extension cord is used with this system, it must be at a minimum, 12-gauge, 3 wire, grounded, SJ Quality, 60 Degree C, less than 50 ft. long.

DO NOT remove the ground prong on the power cord. This will void the warranty on your machine and can be dangerous because it does not protect the user.
