9WALL INSTALLATIONTo install the room air conditioner in the wall, performthe following procedure:1. Remove air conditioner from shipping box. Do notinstall window installation parts (noted inTable 2).2. Determine the location for air conditioner. Makesure there is adequate clearance on the inside andoutside of the wall. Ensure that the power cordwill reach the available socket without an exten-sion cord. Air conditioner can be installed in wallsup to 7 in. thick. Side louvers must never beblocked. Select a wall surface that:•does not support major structural loads such asthe frame construction at ends of windows andunder truss-bearing points•does not have plumbing or wiring routed inside•is near existing electrical outlets or near where anew outlet can be installed•faces the area to be cooled and is not blocked byobstructions•allows unblocked airflow from rear (outside) ofinstalled air conditioner3. The following parts will need to be provided by theinstaller:•wood frame•wood shims•wood screws (no. 10, 1-in. long)4. Working from the inside of the room, find a wallstud nearest the center of the area where the airconditioner will be installed. This can be deter-mined by sounding walls or using a stud finder.5. Cut or knock out a hole on each side of the centerstud. See Fig. 20.6. Measure between the inside edges of every otherstud as shown in Fig. 20.7. Follow all local building codes when building andinstalling frame. Build a wooden frame that willbe placed around the unit in the wall. The framewill reinforce the hole in the wall where the airconditioner is installed and is used to secure theair conditioner to the wall. The frame should havean inner dimension of 20.5-in. width by 14.8-in.height for 73KC_101P air conditioners or 22.8-in.width by 15.7-in. height for 73KC_121P air condi-tioners to ensure that the air conditioner will fitinside the frame. See Fig. 21. The depth of theframe should approximately match the depth ofthe wall. The thickness of the frame will need tobe added to the dimensions to determine the sizeof the hole in the wall.For example, if using 3 /4 -in. thick wood for theframe, the hole would need to be:20 1/ 2 + 3 /4 + 3 /4 = 22-in. wide.8. After the frame has been constructed, check tomake sure that the air conditioner fits correctlyinside it. If the frame is too tight or too loose,adjust the size or re-construct.9. Measure the outer dimensions of the frame anduse those dimensions to cut the hole in the wall.Make sure the hole is level or condensate will notdrain properly.10. Install wooden frame into hole in wall. Make sureframe is properly secured. Fill in the spacebetween the frame and the studs with wood shims(spacers). Nails spacers to studs. If required, pro-vide studs around entire frame to reinforce stabil-ity of wall. See Fig. 22.IMPORTANT: Read entire instructions before cut-ting hole in wall.IMPORTANT: Be sure to measure air conditionerto check size before constructing frame.IMPORTANT: If thickness of the wall covers topand side vents of the air conditioner when it isinstalled, the outer portion of the wall openingmust be widened. The top and side vents must beclear and uncovered.FIGURE 20 — WALL INSTALLATIONLOCATIONFIGURE 19 — STORM WINDOW APPLICATIONS
