Service Central Vacuum System

Locate the main canister unit (usually in the garage, basement, or utility room). Disconnect power before opening. Empty the dirt canister or replace the paper bag when it reaches two-thirds full — a full canister reduces suction by up to 40%. Remove and tap out or rinse the secondary foam/felt filter, let it dry completely before reinstalling. Inspect each wall inlet valve: insert a broom handle to check for clogs, and clean the gasket and spring latch so inlets seal properly. Run the motor for 60 seconds without the hose attached to clear any residual dust from the tubing. Check the exhaust vent to the exterior for obstructions. Lubricate any moving parts per the manufacturer's guide.
