NuTone CV554 Locating the Power Unit, Tubing and Wall Inlet Locations, Stacked Closets or Laundry

LOCATING THE POWER UNIT

•Locate the power unit away from the general living area in an accessible location for emptying the lower dirt cannister and periodically cleaning the filter.

•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 power unit requires a 120vAC power source.

•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 but is not required. The exhaust should not be vented into a wall, a ceiling or a concealed space in the house. If the exhaust line is vented outside the home, Model 393 Wall Cap or a roof vent are recommended.

WARNING: Power unit must not be mounted in a high ambient temperature area such as attic, furnace room, etc.

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. 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.

3.If working from blueprints (or building plans drawn at

1⁄4" = 1 ft. scale), use a 71⁄2" chain as your guide to determine inlet locations.

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

5.Be sure tubing will not interfere with electrical, plumbing or other mechanical installations.

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

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

LOCATING ACCESS KEYS IN

EXISTING CONSTRUCTION

Let's say, for example, you have a two-story house and you want to locate the power unit in the basement. If you can't find interior walls on both the first and second floors which line up and are free from obstacles. How do you get from the basement to the attic?

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 illustration on page 2 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	TUBING
4. A laundry chute could also
provide access from basement
to upper floors.

FIGURE 4

Built-In Appliances. You will often find a hollow space behind built-in kitchen appliances. If this space lines up with an obstruction-free interior wall above or a closet, this might be a key to your installation. See Figure 5.

You may also want to consider running exposed tubing through cabinets or cupboards.

FIGURE 5

Cold-Air Return. A cold-air return often provides a straight run from basement to other levels of the house. See Figure 6.

The ductwork is easily cut for access. Seal around the tube when completing the installation.
