1. See “Noise Emission Notes” on page 336 for definitions of noise emissions positions.
2. 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.
