95°F (35°C), it should be turned off and allowed to return to normal temperature

 

before use. The unit may be damaged by exposure to temperatures below -22°F

 

(-30°C) or above 167°F (75°C), or by exposure to humidity in excess of 95%. If

 

a unit exposed to such conditions fails to operate after it returns to a normal

 

operating temperature, contact your local service representative.
