1.    See “Noise Emission Notes” on page 336 for definitions of noise emissions positions. 
2.    The amount of space needed by the unit during normal operation is indicated by the footprint dimensions.
 
Note:  The recommended operating temperature is 22°C (72°F) or lower. At lower temperatures, the risk of failure in 
the unit is reduced. If the operating temperature is above 22°C (72°F) for long periods of time, the unit will be 
exposed to a greater risk of failure from external causes.
