Operating altitude -76.2 to 3,048 m (-250 to 10,000 ft)
Non-operating altitude -76.2 to 9,144 m (-250 to 30,000 ft)
NOTE: For safety, the MCS 5042 unit is equipped with a dew point sensor and control system
which creates an alarm that sounds if the chilled water temperature is lower than the dew point
temperature. This condition might create excessive condensation on the heat exchanger.
Therefore, the unit must be operated in non-condensing operating conditions.
