When emptying the dirt container or filter bag, it is recommended to inspect the permanent filter located inside the unit above the intake ports. If the filter surface appears to be caked in dust, please do as follows :
Do not remove the permanent filter!
1. Unplug the power cord to prevent unintentional operation of the central vacuum. Remove the bottom dirt container by lifting the side latches, one at a time. Set the container aside.
2. If using a filter bag, remove it by grasping the cardboard flange on opposite sides and pull away from the bag adapter fitting.
3. Place an open garbage bag or another large plastic bag around the open end of the unit. Seal the bag to the unit by tying it tight or by grasping the excess bag in one hand to prevent dust from escaping.
4. Reach up under the bag into the bottom of the unit using the bag as a glove. Shake the filter gently to dislodge dust from the filter so that the dust falls into the bag.
5. Remove the plastic bag, empty the dirt container contents into it, including the full filter bag (if applicable), and dispose.
6. Install a new filter bag (if required) and re-install the first container. Use the hooks on the body to hang the dirt container and latch both sides at the same time to ensure the container is aligned with the gasket.
7. Plug the power cord in and verify the proper operation of the vacuum.
