Environmental

The following environmental conditions shall be observed:

Table A-12. Environmental Conditions for Storage or Transport

Temperature
-40 °F to +158 °F
(-40° C to +70° C)

Table A-13. Environmental Conditions for Operation

Temperature
+41 °F to10 4 °F (+5°C to 40°C)
Under extreme conditions of use that are beyond the recommendations above but within the limits of
a supply voltage of –20%, compared to the nominal temperature or the combination of a temperature
of 113 °F (45 °C) and humidity of 75% HR, the ventilator should not malfunction nor endanger the
user. However, operating the device for prolonged periods or repeatedly under such extreme
conditions could result in premature aging of components and more frequent maintenance.
