Central vacuum systems rarely come with a manual covering everything because each of the three components that make up a system can be from independent manufacturers. The main suction unit can be from a manufacturer in California, and the hose and tool set may be a dealer's favorite from a distribution center. Below you will find basic help for the three components: 1) the central vacuum unit, 2) the pipe, wiring and inlets, and 3) the hose and accessories.
Maintenance Information Basics
Taking care of a central vacuum unit is quite easy. The only required maintenance is changing or cleaning the filter and dumping the debris. If the top doesn't lift off to access a filter then twist or unlatch the base to perform the maintenance. There is nothing to lube or oil on the central vacuum system including the motor. For more maintenance tips, visit the motor page for your brand in the yellow bar below.

Primarily for MD SilentMaster, ModernDay, Flo-Master, AirMaster. Corresponding components maybe wired the same way in other systems.
Maintenance Information Basics
Taking care of a central vacuum pipe is easy. It rarely, if ever, requires maintenance. However, there is a way to clean out and deodorize the hose and pipes using Tornado Central Vacuum Maintenance Cloths. Maintaining the inlet valves is done as needed. Parts are not sold separately so if a door breaks replace the entire inlet valve. Here is how to fix air leaking inlets.
