1. 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 high by 2 wide It is crucial that you make an accurate cutout and we have supplied a template to help you 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 cutout2. 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 30 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 lev
