Having a good preventive maintenance program for your vacuum equipment ensures years of reliable operation. Most furnace manufacturers and third-party suppliers can provide training on their systems, offer troubleshooting advice and help design preventive maintenance programs, which always need to be customized to the individual company running the equipment. Often, however, help with process applications is outside the scope of their work, so if this is needed, it should be negotiated before purchase.
Vacuum are not unique. As with any piece of manufacturing equipment, proper maintenance at regular intervals is essential to extend service life and provide (relatively) trouble-free operation. The operating and maintenance manuals supplied with most furnaces provide detailed information on maintenance and troubleshooting. While these manuals should be read and understood before commencing furnace operation, this is seldom done. Instead, people refer to the manual only when a problem occurs. Reading the manual first, as a preemptive step, helps to more quickly maintain the furnace.
