There should be at least 12 inches of space between the power unit and the ceiling for adequate motor cooling. If mounting on concrete walls, use a masonry bit to drill holes and then secure the mounts with plastic or lead anchors for added stability. Doing so will ensure a secure fixture that is adequately supported. If mounting on plaster or panel walls, secure the unit to the studs to prevent movement or damage.

Cyclonic units, which separate dirt and debris using centrifugal force, must be vented outdoors to expel fine particles. Other types of power units can also be vented outside, though it is optional. Proper venting is crucial to maintain indoor air quality and ensure the longevity of your central vacuum system.

Running PVC Piping

To install a PVC piping system for a central vacuum, you need to connect multiple inlets to the power unit to ensure a smooth flow of dirt and debris. The piping is usually installed behind the walls, and each inlet valve is connected to the central vacuum unit. It’s important to use long sweep elbows instead of short elbows to maintain vacuum efficiency and airflow.

When cutting PVC tubing, follow these steps:

  1. Make sure to measure accurately from the base of the pipe stop on the inside of the fitting.
  2. Cut the tubing as straight and square as possible, using a mitre box if available.
  3. Remove rough edges with a utility knife, coarse sandpaper, or a pipe deburring tool.
  4. Dry-fit the pieces before gluing them to ensure proper alignment.
  5. Apply cement to the tubing and twist it a quarter turn when inserting it into the fitting to distribute the cement evenly.
  6. Remove any excess cement to maintain airflow and prevent clogs.
  7. The PVC solvent cement creates an airtight seal by chemically welding the fitting to the tubing.

Installing Inlet Valves

The installation of inlet valves requires precision and an eye for detail. Here are the steps to follow:

  1. Use a stud finder to locate a suitable site between studs, ensuring open space behind the wallboard.
  2. Before proceeding, check the opposite side of the wall for any obstructions, such as utilities or outlets.
  3. Avoid installing inlets behind doors or in walls that house pocket doors.

To install the inlet valve, follow these steps:

  1. Drill a hole in the wallboard with a diameter between 2-1/4 and 2-1/2 inches to ensure a proper fit for the valve.
  2. During installation, connect the low-voltage wires to the terminals labelled ‘low voltage only’ to ensure proper system functionality.
  3. Ensure the gap for connecting the low-voltage cable to the inlet valve is approximately 5/8 inches to provide enough space for a secure and proper connection.
