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. A bottom mounting bracket is provided for ease of installation, but is not required.
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 unit being installed.
4.The unit is suitable for 0 inch clearance from the unit, and from the supply and return air ducts.
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 and bottom mounting bracket location, if desired. See Figure 3.
3.Mount bottom mounting bracket, if used.
4.Hook top rain flashing under back bend of top. Top rain flashing is shipped secured to the right side of the back.
5.Position unit in opening and secure with 5/16 lag bolts. Use 5/16” diameter flat washers on the lag bolts.
6.Secure rain flashing to wall and caulk across entire length of top. See Figure 3.
7.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.
8.On side by side installations, maintain a minimum of 20 inches clearance on right side of unit to allow access to control panel and heaters, and to allow proper airflow to the outdoor coil. Additional clearance may be required to meet local or national codes.
