50-423-719Vacuum Systems for MMMP Trades (C-10)
Course Information
Description
Course introduces principles of vacuum systems and interpreting vacuum system schematics. Apprentices will then develop skills related to installing, repairing, replacing and applying troubleshooting principles to vacuum systems and components. Course examines preventative maintenance techniques commonly used on the job. This course was formerly the C-10 module in related instruction for the MMMP apprenticeship.
