Place, Assemble, and Install the Support Brackets
Determine the position that the V-support will
be placed within the support rail by placing the
support rail against the back edge of the stool.
Note the nearest side hole location in the
support rail that is past the sill.
Note: If the wall extends past the sill, note the
nearest side hole in the support rail that is past
this construction.
Assemble the V-support to the support rail
using two type D nuts and bolts, at the location
noted. The shortest portion of the V-support
should be placed facing the neck of the
support rail. Repeat for second V-support
and support rail.
Thread a type E bolt about 1/2 of the way into the
outer face of the shortest angle of each V-support.
Line up the V-notches in the support
assemblies on the left and right marks on the
stool. Make sure that the support rail is against
the back of the stool and drill two 1/8
″
pilot
holes into the stool through the holes in the
support rail neck. Attach the support
assemblies to the stool using two type C
screws in each assembly.
Adjust the type E leveling bolts against the
outside wall so that the assemblies have a
slight tilt to the outside. Use a level; about
a 1/2 bubble will be the correct slant
to the outside.
NOTE: Use a wood block between the leveling bolts
and the wall if the wall is weak or if the weight of the
air conditioner falls between the studs in the wall.
