The air conditioner is constructed with removable

aluminum panels. The front access panel provides

access to the control box, control panel, and

tests the air conditioning filter and regulates the

amount of air returned to the unit. The condenser

coil grille and fan guard protects the condenser

coil and fan. A fresh air inlet screen permits the

entry of outside air and is controlled by the

damper door with the control spring and chain.

An intake cover provides for attachment of a

panel covers the top of the unit.
