Through-the-Wall Installation
Make certain a wall receptacle is available close to
the hole location or make arrangements to install
a receptacle.
The cord length for the 115-volt models is 72
² to
the right and 47² to the left. For the 230/208-volt
models the cord length is 65² to the right and 39²
to the left.
The air conditioner wall case may be installed
flush with the inside wall or flush with the outside
wall.
The finished sides of the opening should be
structural wall members.
Lintel
—Use a lintel in brick veneer and brick and
block types of wall to support the bricks or blocks
above the opening. Do not allow the wall case to
be used in lieu of a lintel.
Flashing
—Install flashing (drip rail) as shown to
prevent water from dripping inside the wall and
down the outside of the building.
