Central Vacuum Power Unit Mounting Instructions

Read all installation instructions carefully before installing your built-in vacuum power unit.

Improper installation of this unit could void your warranty. Installation should be performed only by a qualified built-in vacuum specialist.

  1. Install the mounting bracket high enough to allow the bottom of the power unit to hang a minimum of 6 inches above the floor. Secure mounting bracket to wall using two (2) #10 x 1 1/2 inch screws. Holes are provided for 13" to 16" stud centers. If a stud cannot be located, use wall anchors or toggles for maximum strength.
  2. Run two inch (2") vacuum tubing from wall inlet on right or left side of power unit. Do Not glue or cement the connection to the unit! Use the red or white cap provided to seal the power unit intake not used.
  3. Connect the two low voltage wires from the wall inlet to the leads on the power unit using the blue wire nuts provided.
  4. Make sure that filters and bag gasket are properly in place and that the lid is on the unit.
  5. Plug in the power unit.
