SYSTEM PLANNING AND LAY O U T The NuTone Central Cleaning System consists of a Power Unit, PVC Tubing and Fittings, Wall Inlets, a flexible Hose and various cleaning Attachments. The Power Unit is designed to be wall-mounted away from the living area of the home and connected to the living area by means of permanently installed in-wall tubing, fittings and inlets.
THE SPLIT-LEVEL HOUSE Like the two-story house, the split level installation commonly calls for a two-level trunk line. Here, the power unit is located in the garage. The intake tubing runs exposed up the garage wall and into the ground level section's attic.
GENERAL INSTA L L ATION GUIDE TOOL LISTING Depending on your installation, you may require the use of these tools. The power tools are recommended to make your installation proceed quickly. • Wire strippers • 1/4" Drill • Level • Flashlight •...

INSTALLING THE TUBING Use the following installation guidelines when installing tubing. 1. Start tubing installation at farthest inlet and work toward the power unit. 2. Tubing run to the power unit should be as straight as possible. 3. When assembling sections with elbows and tees, make sure the curve in the fitting is aligned so that the air flows toward the power unit.
WALL INLET INSTALLATION MODEL CI370 WALL INLET (CF361 and CF361F Rough-In) 1. Remove the cardboard plaster guard. 2. Refer to Figure 14. For some drywall or panel con- struction, the plaster frame will extend beyond the fin- ished wall. In this case, remove plaster frame from mounting bracket by removing mounting screws.
All electrical devices such as the electrified inlet should be reported to the construction electrician for listing on the inspection report for building inspection purposes. NOTE: Plumb inlet to tubing using NuTone Model CF382S 90° Ell fitting. NOTE: All location and installation direct connect...

I N S TA L L ATION IN EXISTING C O N S T R U C T I O N Locating Access Keys in Existing Construction Unless your home is a ranch-style house where a single trunk line can run directly through the attic or basement, you should first investigate your house to find the key to running your tubing from level to level.
NuTone Central Vacuum System. Now, you can begin installation. The first step to install the inlet tubing which connects the wall inlets to the branch lines.

Drilling The Access Holes Once you are certain that you’ve located the center of the wall directly above the inlet location, use a 2 1⁄2” hole saw to cut the access hole through the wall plate or header and into the wall cavity. (A 1⁄2” drill is recommended.) Carefully remove the drill from the hole.
Wall Inlet Installation The wall inlet design allows you to work outside the wall - where assembly is easy and all the parts you need are accessible. First, you make a cutout into in the wall and locate the flexible tubing attached to the inlet line which you previously threaded into the wall.

Obstruction in the hose. A blockage in the hose can be determined by inserting the hose into any Wall Inlet and, while Power Unit is running, check each additional inlet for normal suction by holding the palm of your hand over the open inlet.
Page 37
Possible Remedy 1a. Remove disposable filter bag or empty debris bucket as described in Homeowners Guide and install replacement. 1b. Insert handle end of hose into utility valve at Power Unit. Turn Unit on. This will reverse normal air flow through the hose and dislodge any clogs.
