THE RANCH STYLE HOUSE

Here the power unit is mounted in the garage. The intake and exhaust tubing, the only exposed tubing in the installation, runs up the garage wall and into the attic. The trunk line runs horizontally through the attic from the power unit to the farthest inlet location. Branch lines spread throughout the attic, connecting the trunk line to the inlet tubing. Each inlet tube is threaded vertically through an inside wall. Located in hallways and in large rooms, the inlets are placed to provide maximum access to all cleaning areas. See Figure 1.

THE TWO-STORY HOUSE

A double-trunk line system is commonly used in two-story houses. In the installation shown at right, the power unit is mounted in the basement. The intake tubing runs up the basement wall and connects to the main trunk line, which runs along the unfinished basement ceiling. Two first-floor inlets are connected to the basement trunk line by vertical inlet lines run through interior walls. In the center of the house, a vertical branch line runs from the basement trunk line, through stacked closets, up into the attic. A second trunk line runs across the attic and two branch lines connect to inlet lines which are dropped down through upstairs interior walls. See Figure 2.

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.

Generally, an installation will require 3 to 4 inlets and 16 to 20 feet of tubing per inlet. It is suggested that a floor plan be used to more accurately determine the quantity of materials needed.

Use the following examples as an aid in planning the installation in either new or existing construction. You should be able to adapt the examples shown to your specific home layout.

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. Two branch lines connect this part of the trunk line to inlet lines which are dropped inside interior walls. A vertical branch line runs to the upstairs attic, where the trunk line branches into a T-shape. This trunk line connects to two upstairs inlet lines and to one inlet line which drops through an upstairs wall and down into the third-level utility room to service this entire level. See Figure 3.

LOCATING THE POWER UNIT

• Locate the power unit at the lowest possible position away from the general living area in an accessible location for changing the filter bag or debris bucket.

• When planning, remember the power unit is equipped with an inlet to service a garage, basement, utility room, etc., wherever it is located.

• Locate the power unit within six feet of a grounded electrical outlet. The VX475 and VX550 power units require a 120 V, dedicated 20-amp branch circuit with a NEMA 5-20R receptacle. The VX1000 power unit requires a 240 VAC, dedicated 20-amp branch circuit with a NEMA 6-20R receptacle.

• Do not locate the power unit close to a source of extreme heat (i.e., water heater) or in an area with a high ambient temperature (i.e., attic, furnace room).

• If the power unit is located in a closet or a small utility room, make sure the area is well-ventilated (i.e., with door louvers).

• Exhausting the power unit to the outside is recommended for optimal performance. The exhaust should not be vented into a wall, a ceiling or a concealed space in the house. The exhaust line should be vented outside the home using a Model 393 or CI330 wall caps.

TUBING AND WALL INLET LOCATIONS

1. Locate inlets on interior walls, choosing central locations which allow several rooms to be cleaned from a single inlet using a 30-foot long hose.

2. The tubing installation should consist of a main trunk line running from the farthest wall inlet to the power unit location, with branch lines running to each additional inlet. Keep all tubing lines as straight as possible and use as few fittings as possible.

3. Beginning at the area farthest from the power unit, choose a tentative inlet location. Measure 30 feet from the proposed inlet location to the farthest corner of the rooms to be cleaned by that inlet to determine if inlet location is proper. If working from blueprints (or building plans drawn at 1⁄4" = 1 ft. scale), use a 7½" chain as your guide to determine inlet locations.

4. Locate inlets within six feet of an electrical receptacle to allow use of optional current-carrying hose.

5. Be sure inlets will not be blocked by doors or furniture.

6. Be sure inlets will not interfere with electrical, plumbing or other mechanical installations.

7. Move tentative inlet location if necessary. Use the same procedure to determine each additional inlet location, always working toward the power unit.

WORKING WITH PLASTIC TUBING

Cutting the Tubing

Before you cut a length of tube, accurately measure the length you need. Allow 5/8” of tubing for inserting into fittings and 1 ½” for placing into flexible tubing. Cut the plastic tubing with a hacksaw, making sure that the cut is exactly square. (You can use a tube cutter if one is available.) Use wire cutters or tin snips to cut flexible tubing. The 8” lengths of flexible tubing supplied with each inlet should not be cut. See Figure 4.

Use a small knife to remove any burrs from the inside of the tube. You can also use steel wool to remove burrs. The burrs must be removed or they may impede air flow of form clogs by snagging hair and carpet thread. See Figure 5.

Next, use a file to slightly bevel the outside of the tube so that it will easily slide into the fitting. Use steel wool or a light grained sandpaper to buff the surface of the tube which will be glued. This will clean the tube and assure a good seal. See Figure 6.

GENERAL INSTALLATION 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. Also, plan a mask when cutting ducting (PVC dust) and gloves when using glue.

WARNING

When applicable local regulations comprise more restrictive installation and/or certification requirements, the aforementioned requirements prevail on those of this document and the installer agrees to conform to these at his own expenses.

Making a Joint

Insert the tube into the fitting, aligning the two parts as they will be installed. Mark the tube and the fitting so that you can quickly realign the joint. See Figure 7.

Apply cement only to the outside of the tube. Dab the cement generously in an inch-wide band. Insert the tube into the fitting with the alignment marks a quarter turn apart, and then quickly push and turn the fitting to align the marks and spread the cement. Allow one minute for the joint to dry. You may also use electrical tape or duct tape to further seal the joint. See Figure 8.

Cementing Flexible Tubing

Make sure the ends of the flexible tubing are even—trim if necessary. When you join flexible tubing to plastic tubing or to an inlet mounting plate, apply cement to both the inside of the flexible tubing and the outside of the plastic tubing or mounting plate tubing ring. Twist the two pieces as you join them to evenly spread the glue. Allow five minutes for the cement to set in flexible tubing. You may also use electrical tape or duct tape to further seal the joint.

Secure Wire to Tubing

The low-voltage power wiring is run along with the tubing. To insure that the wire is secure and will not hang-up in a wall, use electrical tape to attach the wire to the tubing. Tape the wire approximately every 12-18 inches. See Figure 9.

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.

4. Branch lines should always join the trunk line from above or from the same level. Never join a branch line from an angle below the trunk line.

5. Refer to Figure 25 on page 9. Run low voltage wiring (Model 376UL) and secure wiring to tubing as tubing is installed. Model CF380 Pipe Support can be used to support long runs of tubing (position near joists) and to clip wire along tubing. Secure tubing to joists or studs. Leave approximately 6" of wire for connection to each inlet.

6. Cut a 2 ½" diameter hole in sole plate, header or stud directly in line with opening of inlet bracket fitting.

NOTE: See Figure 13 for center line dimensions.

7. Refer to Figure 14. Measure length of tubing needed to connect inlet to trunk line. Allow approximately 3⁄4" of tubing for inserting into fittings.

8. Refer to Figure 15. Cut tubing, keeping cut square.

9. Refer to Figure 16. Remove burrs from both inside and outside of tubing.

10.Before cementing, pre-assemble section to inlet fitting, check for proper length.

11.Refer to Figure 17. Apply PVC cement (Model 379) to outside of tubing. Coat tubing approximately 1" back. Take care to keep cement from inside of tube.

12. Refer to Figure 18. Insert tubing into fitting with a twisting motion to evenly spread cement. Be sure tubing is firmly seated in fitting.

13. If fittings have been attached to tubing at the end opposite the inlet bracket, be sure alignment is proper before cement sets.

14.Refer to Figure 19. Tape wire to tubing to hold in place and insert through hole in inlet bracket.

15.Connect each inlet line and branch line into main trunk line. Complete low voltage wiring as main trunk line is continued back to power unit.

WALL INLET INSTALLATION

Model CI370 Wall Inlet (CF361 and CF361F Rough-In)

1. Remove the cardboard plaster guard.

2. Refer to Figure 20. For some drywall or panel construction, the plaster frame will extend beyond the finished wall. In this case, remove plaster frame from mounting bracket by removing mounting screws.

NOTE: When using the model CF361 and CF361F inlet bracket on walls thinner than 1⁄2", use a 1⁄4" spacer (not furnished) between the wall and the inlet bracket. See Figure 23. Spacer may be made from plywood, Masonite™, etc. Contact cement may be used to hold spacer in place during assembly. Configuration of spacer may vary depending upon installation.

3. Refer to Figure 21. Connect the red striped wire of the 2-conductor low voltage cable to the unused terminal screw on the inlet. Connect the remaining wire to the black pigtail wire. Cap off both wires using wire nut (supplied).

NOTE: The LED indicator light used in the CI370 is polarity sensitive. If the 2-conductor cable used to connect the inlet to the power unit does not have a polarity marking and the CI370 is wired backwards, no damage will result; however, the indicator will light RED instead of GREEN when the hose is inserted into the inlet. To correct this condition, simply reverse the 2-conductor connections at the CI370 inlet.

4. Guide excess wire back through the hole in inlet bracket and flanged fitting.

5. Refer to Figure 26. Place inlet into mounting bracket and secure.

NOTE: When wall inlets are installed in walls that are less than 1⁄2" thick or when inlets are installed back-to-back in a wall, the tube of the wall inlet may extend into elbow area of the flanged fitting and cause blockage. Shorten the wall inlet tube to prevent this condition. Refer to Figure 24.

For extra thick walls, use Model 399 Extension Sleeve to connect inlet to the flanged fitting.

Model 360 Wall Inlet (CF361 and CF361F Rough-In)

1. Follow steps 1-2 as above.

2. Refer to Figure 25. Connect 2-conductor low-voltage wire to terminal screws on back of wall inlet.

3. Follow steps 4-5 above.

CI390 & CI395 ELECTRAVALVE™ELECTRIFIED INLET INSTALLATION (CI395RK ROUGH-IN)

1. See Figure 27. Fasten the mounting plate to a stud within three studs (48") of an electrical outlet box. Measure and mark the wire 10" from the plug (A). Feed the wire through the top hole in the mounting plate (just above the circular opening). Snap the molded plug into the mounting plate as pictured (B). This will keep it secure and out of harm’s way during drywalling and finishing. Line up the wire at the previously measured 10" mark with the strain of relief channel on the back of the mounting plate. Secure it in place with the supplied wire tie (C).

2. Run the inlet wire to the adjacent electric box. If you must run wire through a stud, drill directly through the center of the stud (D).

3. See Figure 28. Place the exposed ends of the two wires into the electrical box through a strain relief channel (E). Tighten the strain relief channel (do not overtighten) on the white sheathing leaving 1⁄2" of this sheathing exposed inside of the outlet box.

Fold the 6" of black and white wire into the outlet box. Leave the wires to be connected by the electrician when plug receptacles are being installed. (Attention: Power tools such as routers are not recommended for use with the inlet installation, as removal of drywall with these devices may cause damage to the mounting plate and/or inlet plug).

4. Once drywall and finishing processes have been completed, remove molded plug from mounting plate (with the aid of a slot screwdriver) and snap it into the wing slot at the back of the inlet (F). (NOTE: molded plug fits one way only, with the narrow opening at the top). Insert inlet into the mounting plate and secure inlet to mounting plate with screws provided.

NOTE: 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.

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. Look for an accessible area free from obstructions that will accommodate the 2" tubing.

If you understand how your existing home is constructed, it can be relatively easy to find access routes to run the tubing. Refer again to the illustrations on pages 3-4 as you consider your home construction.

Some of the keys you might find in your home are illustrated here.

Stacked Closets or Laundry Chute

Many homes will have an upstairs closet located directly above a downstairs closet. It is easy to run the tubing from one floor level to another inside these stacked closets. In these installations the tubing is often left exposed inside the closets. See Figure 30. A laundry chute could also provide access from basement to upper floors. You may also want to consider running exposed tubing through cabinets or cupboards.

Cold-Air Return

A cold-air return often provides a straight run from basement to other levels of the house. See Figure 31. The ductwork is easily cut for access. Seal around the tube when completing the installation.

Use the following procedures for installation in existing construction. Wall inlets in existing construction may be accessed from below (basement or crawl space) or from above (attic). Instructions apply to either method.

Starting from farthest wall inlet location, install each inlet as described below. Working back toward power unit, connect each inlet line and branch line into main trunk line. See page

26. Complete low voltage wiring as main trunk line is

continued back to power unit. Mount power unit and complete wiring. See pages 31-33.

AVOIDING IN-WALL OBSTACLES

The tubing which connects the inlet into the trunk line is threaded through interior partition walls. After you’ve chosen an inlet location, make sure the wall doesn’t contain some hidden obstacle which will prevent you from running tubing to the inlet.

Exterior Walls

. The insulation in these walls will

prevent you from running tubing through them.

Electrical Wiring

. Wiring may not obstruct your

tubing, but you should always make sure that tubing does not damage the wiring. Electrical outlets and wall switches are signs of wiring.

Ductwork

. Avoid choosing a section of wall that

contains ducting. If you see signs of ductwork—such as floor or ceiling registers—move your inlet location to another section of the wall.

Plumbing

. Plumbing may or may not prevent you from

running tubing through a wall. If you must choose a plumbing wall for an inlet location, be extremely careful when making a cutout in the wall.

Wall Studs

. Make sure your location is between wall

studs. Locate studs by tapping walls, looking for electrical outlet (usually fastened to studs), or noticing finishing nails in the floor molding.
