INSTALLATION INSTRUCTIONS
WALL MOUNTING INFORMATION
1.These units are secured by wall mounting brackets which secure the unit to the outside wall surface at both sides.
2.On wood frame walls, the wall construction must be strong and rigid enough to carry the weight of the unit without transmitting any unit vibration.
3.Concrete block walls must be thoroughly inspected to insure that they are capable of carrying the weight of the installed unit.
MOUNTING THE UNIT
1.Two holes, for the supply and return air openings, must be cut through the wall as shown in Figure 3.
2.Locate and mark lag bolt locations, if desired. See Figure 3.
3.Hook top rain flashing under back bend of top. Top rain flashing is shipped attached to the back of the unit on the right side.
4.Position unit in opening and secure with 5/16 lag bolts; use 7/8 inch diameter flat washers on the lab bolts.
5.Secure rain flashing to wall and caulk across entire length of top. See Figure 3.
6.For additional mounting rigidity, the return air and supply air frames or collars can be drilled and screwed or welded to the structural wall itself (depending upon wall construction). Be sure to observe required clearance if combustible wall.
