NuTone manufactures central vacuum systems comprised of a power unit, PVC tubing, wall inlets, a flexible hose, and cleaning attachments. These systems are designed for residential use and involve permanent in-wall tubing connecting the power unit to inlets located throughout the home. Installation requires careful planning and adherence to safety guidelines. This article details system planning, installation procedures for various construction types, and provides an overview of available models based on provided documentation.
System Planning and Layout
Proper system planning is crucial for optimal performance. The NuTone central cleaning system is designed with a power unit intended for wall mounting, separate from living areas, connected via permanently installed in-wall tubing and inlets. Generally, installations require between three and four inlets, with approximately 16 to 20 feet of tubing allocated per inlet.
When determining inlet locations, it is recommended to position them on interior walls in central locations. This allows for cleaning multiple rooms from a single inlet using a 30-foot hose. Caution should be exercised to avoid outdoor installations. Safety precautions, including wearing safety glasses and gloves, are recommended during installation, servicing, and cleaning.
Installation in New Construction
Specific details regarding installation in new construction are limited within the provided documentation. However, the documentation references dimensional charts and mounting/wiring instructions for models CV350, CV353, CV450, and CV553. These instructions, as detailed in the CV350 series installation manual, cover mounting and wiring procedures for the power unit itself.
Installation in Existing Construction
Installation in existing construction can be approached from below (basement or crawl space) or above (attic). The process involves accessing the partition wall and centering an access hole. To determine the center of the wall, measure half its thickness, accounting for baseboards if present.
For basement installations, tubing is assembled to the inlet flexible tubing and inserted into the access hole. Basement inlet lines typically require shorter runs, approximately 18 inches from the floor to the inlet. It is often recommended that basement installations be performed by two people after the access hole has been cut.
Wall Inlet Installation – Specific Models
The documentation details specific installation instructions for the CI367 VacuSweep® inlet valve. Three connection methods are outlined: connection from below, connection from behind, and connection in a wall.
Connection From Below
This method involves measuring the distance (X) between the kickplate face and the inside edge of the cabinet. Add 2 ¾ inches to this measurement to determine the reference mark for drilling.
Connection From Behind
Similar to the connection from below, this method also requires measuring distance (X) and adding 2 ¾ inches to establish the reference mark.
Connection in a Wall
For wall installations, locate studs and position the inlet valve clear of vertical studs, ensuring free access for connection to the central vacuum tube.
Tubing and Cementing Procedures
When joining flexible tubing to plastic tubing or an inlet mounting plate, cement should be applied to both the inside of the flexible tubing and the outside of the plastic tubing or mounting plate tubing ring. The pieces should then be twisted together to evenly distribute the adhesive. A five-minute setting time is required for the cement to cure. It is important to ensure the ends of the flexible tubing are even, trimming if necessary, before cementing.
