5. Indoor Unit Installation Positioning for mounting console unit Step 2 Mount the support brackets. Be sure that the brackets have been fixed firmly enough to withstand 4 times the weight of the unit. If wall anchors are needed for the four side screws, install them at this time.

6. Indoor Unit Installation Marking hole location Step 1 The piping and wiring can exit the console unit in one of six directions. Left side, right side, back left, back right, left down and right down. Knockouts are provided on the left and right sides of the unit for piping exiting either of these positions.

8. Indoor Unit Installation Drilling the hole in the wall to install the piping Step 1 When the piping and wiring exits the console unit at the back of the unit, special attention is required for the angle of the hole drilled. Find the location on the exterior wall where the piping and wiring will exit the building. Drill a 2 ½” diameter hole at a slight downward angle from the inside wall towards the outdoor wall so that the outside hole is a ¼” lower than the hole on the inside.
