Locating Access Keys inExisting ConstructionUnless your home is a ranch-style house where a singletrunk line can run directly through the attic or basement,you should first investigate your house to find the keyto running your tubing from level to level. Lookfor an accessible area free from obstructions that willaccommodate the 2" tubing.If you understand how your existing home is constructed,it can be relatively easy to find access routes to run thetubing. Refer again to the illustration on page 2 as youconsider your home construction.Some of the keys you might find in your home areillustrated here.Stacked Closets or Laundry ChuteMany homes will have an upstairs closet located directlyabove a downstairs closet. It is easy to run the tubingfrom one floor level to another inside these stacked clos-ets. In these installations the tubing is often left exposedinside the closets. See Figure 30. A laundry chute couldalso provide access from basement to upper floors. Youmay also want to consider running exposed tubingthrough cabinets or cupboards.Cold-Air ReturnA cold-air return often provides a straight run from base-ment to other levels of the house. See Figure 31. Theductwork is easily cut for access. Seal around the tubewhen completing the installation.Use the following procedures for installation in existingconstruction. Wall inlets in existing construction may beaccessed from below (basement or crawl space) or fromabove (attic). Instructions apply to either method.Starting from farthest wall inlet location, install each inletas described below. Working back toward power unit,connect each inlet line and branch line into main trunkline. See page tbd. Complete low voltage wiring as maintrunk line is continued back to power unit. Mount powerunit and complete wiring. See page 8.Avoiding In-Wall ObstaclesThe tubing which connects the inlet into the trunk line isthreaded through interior partition walls. After you’ve cho-sen an inlet location, make sure the wall doesn’t containsome hidden obstacle which will prevent you from run-ning tubing to the inlet.Exterior Walls. The insulation in these walls will pre-vent you from running tubing through them.Electrical Wiring. Wiring may not obstruct your tub-ing, but you should always make sure that tubing doesnot damage the wiring. Electrical outlets and wall switch-es are signs of wiring.Ductwork. Avoid choosing a section of wall that con-tains ducting. If you see signs of ductwork-- such as flooror ceiling registers—move your inlet location to anothersection of the wall.Plumbing. Plumbing may or may not prevent you fromrunning tubing through a wall. If you must choose aplumbing wall for an inlet location, be extremely carefulwhen making a cutout in the wall.Wall Studs. Make sure your location is between wallstuds. Locate studs by tapping walls, looking for electri-cal outlet (usually fastened to studs), or noticing finishingnails in the floor molding.
