Start by marking the location of the power unit’s mounting bracket (Image 1). The unit is heavy and must be mounted to a wall stud for support. Choose a spot that is accessible to the main trunk line pipe and has enough open area around it to allow you to empty the canister.
Mount the bracket and ensure that it is level. Attach the power unit canister to the bracket (Image 2).
Use a probe to mark where the trunk line pipe needs to come through the wall to meet the power unit’s vacuum inlet (Image 1).
Using a drill-mounted hole saw, cut the hole in the wall. Feed the pipe through the hole (Image 2).
Pull the low voltage wiring from the vacuum inlets through the hole.
If installing the power unit in the garage, place a fire stop bracket over the pipe hole (Image 3). This is a fire code requirement.
Cut off the incoming trunk line pipe. Leave a stub end long enough to fit into an angle fitting (Image 1).
Use PVC cement to glue the angle fitting to the incoming pipe stub (Image 2). The angle opening should fit into the power unit vacuum inlet, but do not glue it in place as you will need to remove the canister to clean it from time to time.
