On wood frame walls, the wall construction mustbe strong and rigid enough to carry the weight ofthe unit without transmitting any unit vibration.3. Concrete block walls must be thoroughly inspectedto insure that they are capable of carrying theweight of the installed unit.MOUNTING THE UNIT1. These units are secured by wall mounting bracketswhich secure the unit to the outside wall surface atboth sides. A bottom mounting bracket is providedfor ease of installation, but is not required.2.
