How to use: This heater car is designed to be used in electric service areas. Just place it in the appropriate area, and it will provide steam for heating passenger cars. Note that it has no couplers, so you'll need to handle the connection part carefully. If you want to add couplers, make sure to use the existing mounting screws. Maintenance: Since it's unpainted with minimal tarnish, you don't need to do much for appearance maintenance. However, keep it in a dry place to prevent further tarnishing. When storing, use the original box and foam to protect it from scratches. In case of any issues, contact us right away. We offer a 30 - day no - questions - asked money - back policy for your peace of mind.
