Measure the length of pipe, making sure your cuts are straight and clean. Use a sharp knife or sandpaper to eliminate burrs that might collect dust or hair that could form a dirt trap. Starting with the inlet valve farthest from the power unit, begin test fitting then gluing together sections of piping. Join sections of piping to the main trunk line which ties into the Beam power unit. Splice together the low voltage wires along the trunk line. Run and connect the trunk line to the Beam power unit. If mounting the power unit in the garage, drill a pilot hole through the wall using a wire coat hanger to check location and for obstructions. Then cut a 2 1/2" hole though the wooden joist above the masonry wall between the basement and the garage. Feed piping into garage to unit.
