SYSTEM PLANNING AND LAYOUT

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 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 EXHAUST 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.

3 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

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.

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.

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.

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.

AR0019

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.

7 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.

CAUTION

When tubing is run through the wall stud, sole plate, headers or else where building materials will be attached, place a nail (Model 378) over that area (on both sides if necessary) to prevent nails from piercing tubing.

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

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.

FIGURE 30

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.

12 FIGURE 31

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.

INSTALLING THE INLET TUBING

When your planning is complete, you will have to determine where all the inlets and the power unit will be located. You have also mapped out the location of your trunk line and found the access you need to run vertical tubing from one level of your house to another level. You should have acquainted yourself with the methods of joining plastic tubing and acquired the tools you’ll need to install your

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. As explained before, the inlet lines run inside interior walls. You will find access to these walls through your attic or basement. Briefly, you want to find the exact location in the wall, drill an access hole through the wall plate or header, and insert the tubing into the wall cavity.

This part of your installation requires close observation and careful measurements. Take your time and make sure you accurately line up your access holes with the locations you’ve chosen for your wall inlets.

Locating Attic Access Holes

Drill the access holes directly above the inlet location.

To accurately locate the access hole, you must find the space between wall studs where the inlet is to be located.

Observe the area around the inlet location. Look for references you might be able to find in the attic: electrical wiring, ductwork, doorways, etc. Measure and note the distance from these references to the inlet location.

Enter the attic and find the inlet wall. Have a helper downstairs knock on the top of the wall right above the inlet location; locate the general area by following the sound.

Most likely, you will have to clear away insulation. Ask your helper to continue knocking until you locate the area between wall studs directly above the inlet location.

Next, measure the thickness of the wall. Mark the exact center of the wall where you will drill the access hole.

Remember that the access hole must be placed exactly in the center of the wall.

Drywall

AR0021A

Wall Plate

Drywall

Locating Basement Access Holes

To locate access holes in the basement, remove the toe molding or baseboard at the base of the inlet wall. Carefully loosen the molding or baseboard by inserting the blade of a putty knife behind it. Force another putty knife between the first knife and the baseboard or wall. Gently hammer a cold chisel between the two knife blades, prying the loosened molding away from the baseboard or the baseboard away from the wall.

AR0023

Directly below the inlet location, drill a 1/16” reference hole through the floor into the basement. (If you’re drilling through carpet, use an awl to slightly open the weave. This will keep the carpet from wrapping itself around the drill bit.) Insert a piece of scrap wire or a clothes hanger into the reference hole so you can easily find the hole in the basement.

Once you’ve found the location in the partition wall, you must center the access hole in the middle of the wall.

Measure half the thickness of the wall and mark the center of the wall where you will drill the access hole. If you cannot see the plate, you can determine this measurement from upstairs. At the nearest doorway, measure the thickness of the wall, including the baseboard.

In the basement measure a distance equal to half the thickness of the wall, using the reference hole as a starting point.

13 Drilling the Access Holes

Once you are certain that you’ve located the center of the wall directly above the inlet location, use a 2½” 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.

Cut a piece of low voltage wire which is long enough for the complete inlet line, allowing 6” for connections to the inlet wall plate. Secure the wire to the tubing with electrical tape.

Now, use a flashlight to inspect the wall cavity through the access hole. Make sure no hidden obstacles will interfere with the tube installation. (If this inspection reveals an obstacle, find a new inlet location.) Repeat this procedure in your attic or basement until your access holes are drilled.

AO0014

Assembling the Inlet Tubing

Once you’ve drilled the access holes, you assemble the inlet tubing and insert it into the wall cavity. Refer to “Working

With Plastic Tubing” on pages 5-6 before you begin to assemble the inlet lines.

Select a section of plastic tubing and an 8” section of the flexible inlet tubing. Apply cement to the outside of the plastic tubing and to the inside of the flexible tubing. Join the two pieces together and allow 5 minutes for them to dry.

Tuck the 6” wire lead inside the flexible tubing so that it will not snag inside the wall.

If space permits, you can assemble the entire inlet line by joining two sections of tubing with a stop coupling before dropping the assembly AO0015 into the access hole.

(Remember to only glue the outside of the tubing when joining two pieces of PVC tubing.) Oftentimes, tight attic spaces require you to begin your drop and then join the second section of tubing. Of course, the order of assembly, and the length of tubing required depend on your attic space and your wall height.

14

Whatever the case, insert the completed inlet line into the access hole and thread it down inside the wall. The inlet line should be long enough so that it extends above the joists in the attic; at this height, it can be easily connected to the branch and truck lines. When cutting the inlet tubing to length, remember that your inlet will be placed at 18” above the floor.

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 the wall and locate the flexible tubing attached to the inlet line which you previously threaded into the wall. Then, you attach the flexible tubing to the inlet mounting plate, assemble the other inlet parts, and make the wiring connections. You place the inlet assembly into the wall cutout, sandwiching the wall between the inner and outer parts, and secure the inlet tightly to the wall with two screws.

Assemble and install the wall inlet as shown in the illustrations and as explained in the next few pages.

Be careful and patient as you make your first cutout and install your first inlet by following the procedure step by step

—the other inlets will be easy to install in very little time.

Making the Wall Inlet Cutout

The wall inlet should be located 18” on-center from the floor and directly in line with the attic or basement inlet tubing hole you have already drilled in the wall plate or header. the wall inlet cutout must be exactly 3 7 ⁄

” high by 2 7 ⁄

” wide. It is crucial that you make an accurate cutout, and we have supplied a template to help you.

For a basement installation, assemble the tubing to the inlet flexible tubing in the same way and insert it into the access hole. A basement inlet line is necessarily shorter because it must only reach 18” from the floor to the inlet. Most of the time, Basement inlet lines are more easily installed by two people after the inlet hole has been cut in the interior wall. See

“Wall Inlet Installation.”

Complete all your inlet lines, and then proceed to your inlet installations.

Place the template against the wall so that it is 18” on-center from the floor. Use a level along the top edge of the template to make sure it is square to the wall. Mark your wall for the cutout by tracing around the inside of the template.

Then use your pencil to mark the screw hole locations through punched holes at the top and bottom of the template. Remove the template from the wall.

15

Use an awl or icepick to punch pilot holes where you marked the two hole locations. Now, drill two 3⁄8” diameter holes, using the pilot holes as the centers. Locate and drill these holes exactly as marked with the template.

Attaching the Inlet Mounting Plate

Reach through the inlet hole and locate the inlet tubing.

Raise it up inside the wall until you locate the inlet tubing. If the inlet is connected from the basement, have a helper insert the inlet tubing into the access hole until you can see the flexible tubing. Then, pull the flexible tubing through the inlet hole and remove the low voltage wiring from inside the tube. If the end of the flexible tubing is not even, trim it so that it is exactly even.

Also drill four pilot holes in the four corners of the marked area. Make sure these holes are located inside the marked line. Then, using a utility knife, score along the inside of the marked line. For plaster walls, score the plaster deeply, being careful to stay inside the marked line.

Now, remove the nail flange (used for new construction) from the inlet mounting plate. Use pliers to bend this flange along the scored lines until you can break it off.

Pilot holes must be inside marked line

Nail Flange

Next, use a keyhole saw or a sabersaw to make the cutout.

Again, be extremely careful to cut along the inside of the marked line.

CAUTION

When cutting into plaster walls, make sure the plaster is firm and secure around the cutout area.

O0039A

Cut along inside of marked line

Apply cement to both the inside of the flexible tubing and to the outside of the mounting plate’s tube ring.

Insert the mounting plate’s tube ring in the flexible tubing and twisting the pieces as you join them to spread the cement, and align the mounting plate in a vertical position.

Hold the assembly in place for a few minutes as the cement sets; allow 5 minutes for the cement to completely dry.

Installing the Inlet

When you place the inlet into the wall cutout, the mounting plate and tube guard slip inside the wall; the inlet cover remains on the outside.

AO0044

Now, strip the ends of the two low voltage wires, and then connect the wires to the screw terminals on the back of the inlet cover. Make sure the wires are tightly secured under the terminal screws. When the wiring is complete, assemble the inlet cover to the tube guard and mounting plate. Insert the top screw through the entire inlet assembly until the screw engages the mounting plate.

Completing Inlet Assembly

Once you have attached the mounting plate to the flexible tubing, pull the low voltage wire through the top wiring hole in the mounting plate.

Holding the inlet assembly between your thumbs and fingers, angle the bottom of the mounting plate into the cutout. Push the assembly downward until you have clearance at the top of the cutout.

Push the top of the mounting plate into the cutout and lift the assembly upward until the top screw seats in the predrilled hole.

At this point, the wall should be sandwiched between the mounting plate and the frame plate.

Insert the bottom screw into the inlet cover and through the other parts. Give the screw a few turns until it firmly engages in the mounting plate. Now, level and slightly lower the assembly. Make sure the wall is sandwiched between the inner and outer parts—you’ll be able to feel if mounting plate is firmly centered on the inside of the wall.

Hold the inlet in place and gradually tighten down each screw a little bit at a time. (If you completely tighten down one screw at a time, the mounting plate may pull away from the wall at the loose end and slip back into the cutout.)

Complete all your wall inlet installations in this manner.

If your cutouts are accurate, each wall inlet will install more quickly and easily.

NOTE: If the wall for mounting the Model 360 inlet is less than 1⁄2", a spacer must be used. See Figure 23 on page 9 as a guide.

2. Cut a length of tubing that will extend from inlet opening to a point below floor level (or above ceiling level in attic installation). Tape low voltage wire to tube and insert tube through predrilled hole to a level opposite the wall opening.

3. Apply cement to tube and install flanged wall fitting.

Make sure fitting is well seated and sealed (Figure 33).

ASSEMBLING THE TUBING SYSTEM

Once you have installed all your inlets, you can complete the network of tubing that connects your inlets to the power unit. This network consists of the following parts:

90° Elbows – Used for connecting the inlet lines to the branch lines.

Also used for making smooth 90° turns in branch lines or trunk lines.

Beginning the Trunk Line

Start the inlet line which is farthest from the power unit.

Place 90° elbow onto a section of tubing and align it with the inlet tubing at the height it will run across the attic joists.

Mark the inlet tubing where the elbow will join, allowing 5/8˝ for the tubing that inserts into the fitting collar.

45° Elbows – Used for a 45° tubing turn in branch or trunk lines.

90° Tees – Used to connect branch lines to the trunk lines.

Stop Couplings – Used to join two lengths of tubing.

Flexible Tubing – Used to bypass obstacles or to make difficult S-turns in branch lines. This tubing is supplied in a 36” length; it is not the same as the inlet flex tube.

Now, cut the inlet tubing at the marked line. Make sure the cut is straight and even. Attach the elbow and check its fit.

Then, insert the first section of tubing into the other end of the elbow.

PVC Tubing – 8’ straight sections of tubing used for inlet, branch and trunk lines.

AA0012

Use the tubing and fittings to run branch lines from the inlet tubing to a main trunk line. Begin at the farthest inlet from the power unit and work your way toward the power unit.

When you assemble sections with elbows and tees, make sure the curve in the fitting is aligned so that the air flows toward the power unit.

Assemble the entire network of tubing and fittings, making sure every joint is accurately cut and aligned. Then, go back and cement all the joints. You may run the wiring and make the wiring connections after the network is assembled and cemented, or you may make the wiring connections as you assemble the network. Use the method that best suits your needs.

26 Connecting a Branch Line

A branch line connects the inlet line to the trunk line. Follow the methods previously described for aligning, marking and cutting the inlet tubing. Attach a 90° elbow and run tubing from the inlet line to the trunk line.

Joining Straight Lengths of Tubing

Both branch lines and the trunk lines may require lengths of tubing longer than those 8´ sections supplied. Use stop couplings to join two straight lengths of tubing. Insert one end of the tubing into the stop coupling; join the second length of tubing into the other end of the stop coupling. Stop couplings are also used to join long vertical branches which run from one level to another level of a house.

To align and measure the branch line, attach a 90° tee fitting to the trunk line. Make sure the tee connects with the air flow going toward the power unit. Align, measure, and mark the branch line for inserting it into the tee fitting. Then, cut the branch line to length and insert it into the tee. Check to make sure the cut is straight and even. Connect the next section of tubing to the out-take side of the tee fitting. Continue the trunk line until you come to another branch line junction point.

Make sure air flows toward

Power Unit

To Power Unit

Circumventing an Obstacle

Wherever possible the branch lines should connect to the trunk line in straight paths. The fewer turns in a tubing system, the more efficient air flow. Accordingly, you should locate the inlets to avoid zig-zags in the branch lines. But, sometimes, when you just can’t avoid an obstacle, you are required to construct the tubing around it.

In the example illustrated here, you might run the branch line at an angle to avoid a chimney. Then, once the branch line has run past the chimney, you can use a 45° elbow to turn the branch line back perpendicular to the trunk line. Again, the branch line and the trunk line connect with a 90° tee.

Completing the Trunk Line

Continue to run the trunk line toward the power unit, connecting all branch lines as you go along. Again, make sure you connect all fittings with the air flow toward the power unit.

Bring the trunk line to the access hole you have drilled for the power unit’s intake tube. Place a 90° elbow over the hole and cut the trunk line to fit into this final elbow. Allow 5⁄8˝ of tubing to fit into the elbow’s collar. Connect the elbow to the trunk line so that it aligns over the intake access hole. You will make the intake tube connection itself after you have installed the power unit.

AR0037

You can also use the supplied 36˝ piece of flexible tubing to run a branch line around an obstacle. See “Using Flexible

Tubing,” on page 30.

28

AO0061

When you are satisfied that all fittings and tubing are aligned for maximum air flow, make sure that all your cuts are square and that all joints are tight. Then, prepare the tubing and cement the joints as described in “Working With Plastic

Tubing,” page 5.

Connecting the Low Voltage Wiring

Ideally, you will run the wiring and make all the wiring connections after you have completed the tubing system. Of course, the inlet wiring must be run at the time the inlet tubing is threaded through the walls.

Run the low voltage wiring along the trunk line; at approximately 12˝-18˝ intervals, use electrical tape to secure the wire to the tubing. Then, run wiring along the branch lines from the inlet lines to the trunk line. Also secure this wiring with electrical tape.

At the joint of the inlet line and the branch line, make a two-wire connection. Use wire nuts to make the connections and insulate each connection with electrical tape.

Ass embling a Basement Trunk Line

Basically, the tubing network is assemble the same way for a basement installation. Begin the trunk line at the farthest inlet line from the power unit. Measure and cut the inlet tubing to the length required to align the trunk line with the joists or ceiling. Cement the inlet tubing and connect at 90° elbow. Then, run the trunk line until you reach a branch line junction point.

At the junction of every branch line and the trunk line, cut the trunk line wire and connect it to the branch line wire.

Connect this wiring in groups of 3–one branch wire, one in-coming trunk line wire and one outgoing trunk line wire.

Insulate all wire connections with electrical tape.

Complete all wiring connections up to the power unit’s intake access hole. You will make this connection when you mount and connect the power unit. If, for some reason, you want to connect the wire as you go along, make the same two-wire and three-wire connections where required.

29

Attach the tubing to the joists or ceiling with either perforated metal or support strapping (support strapping is available from NuTone).

Make all branch line connections in the same way you would an attic installation. Make sure that all branch lines enter the trunk line at an angle that is at least levelled with the trunk line. Make sure all the fittings are oriented so the air flows toward the power unit. Complete the trunk line to the power unit location.

Using Flexible Tubing

The supplied 36˝ length of flexible tubing may be used to circumvent an obstacle or to make a difficult turn. In the example illustrated here, the flexible tubing is used in order to run a branch line under a support beam. Attach this tubing to the PVC tubing, cementing only the outside of the

PVC tubing as you would for a hard-fitting connection.

Whenever you use the flexible tubing, you must secure both ends of it with support strapping.

TROUBLESHOOTING GUIDE

Read Before Calling Service Center

Trouble

1. Loss or decrease of vacuum occurs.

Possible Cause

1a. Disposable filter bag or debris bucket are completely full.

1b. 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. If normal suction is felt at all other inlets, insert the hose into a second inlet. If the blockage still exists it is located in the hose. However, if the blockage does not occur when the hose is changed, the blockage is probably located in the tubing system leading to the original inlet.

1c. Obstruction in the tubing system inside the walls.

1d. Wall inlet cover not properly sealed.

1e. Exhaust tubing or vent clogged.

2. Power unit does not start, or shuts off during normal operation with no LED showing red or illuminated.

2a. Defective inlet. Check other wall inlets.

2b. Thermoprotector has been activated OR there is a tripped circuit breaker on the unit.

2c. Blown fuse or tripped circuit breaker on house electrical panel.

2d. Defective hose.

2e. NOTE: This would apply only to the VX550 & VX1000: microprocessor lockup.

3. Power unit fails to stop when the hose is removed.

4. Power unit shuts off during normal operation, lights on unit, wall valve and hose are all red.

5. For VX550 & VX1000 Series. All lights on control panel flash when unit is first plugged in.

2f. Low line voltage.

2g. Bag full sensing has been activated.

3a. An electrical short has occurred somewhere in the system.

4a. Debris bucket and/or direct door not fully closed or attached.

5a. Two or more hoses may be plugged into system.

36 Possible Remedy

1a. Remove disposable filter bag or empty debris bucket as described in Homeowner’s 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.

1c. Insert hose end into any inlet with power unit running, place the palm of your hand over the opposite end of the hose. When you can feel the suction increase, hold your hand over the hose end for a few seconds and then quickly remove your hand.

This procedure repeated several time should clear the obstruction. If the blockage is not cleared, contact your nearest

Service Center.

1d. Check all wall inlet covers to be sure they are closed and sealed tightly.

1e. Inspect and remove any blockages.

2a. Replace defective wall inlet.

2b. Turn unit off for 20 minutes then plug unit back in. If unit does not start, look for the tripped circuit breaker behind the unit, a white button has popped up, push it back to reset it. If circuit breaker trips again, unplug your unit and contact your local

Service Center.

2c. Replace fuse or reset circuit breaker on wall panel.

2d. Replace hose as required.

2e. 1) Push Reset button while unit is engaged OR

2) Unplug unit completely for 60 seconds.

2f. Contact your local Service Center.

2g. Remove and replace disposable filter bag as described in Homeowner’s Guide.

3a. A complete check of all wall inlet and power unit low-voltage control lead connections. Contact your local authorized

Service Center.

4a. Check and close direct door and make sure debris bucket handles are fully locked.

5a. Check all other wall inlets, utility valve at power unit and sweep inlet valve.
