The machine should be located in a clean dry place
where there is free circulation of clean air such that air
movement in through the front and out through the
back will not be restricted. Dirt and dust that can be
drawn into the machine should be kept to a minimum.
Failure to observe these precautions can result in
excessive operating temperatures and nuisance shut-
down of the machine.

making sure the two holes in the base rails of the
unit being stacked on top are over the two pins
located on the top front corners of the unit it is
being stacked on.
