Ambient Air Temperature
Locatethedryerindoorswheretheambientairtemperature
willbebetween40°Fand100°F.Intermittentoperationat
ambient temperatures up to 113°F will not damage the dryer
but may result in a higher dew point or dryer shutdown
duetohighrefrigerantdischargepressure(seeFieldService
Guide).
Donotoperateair-cooleddryersatambientairtemperatures
below40°F.Suchoperationmayresultinlowsuction
pressure,causingfreeze-up.
Callyourlocaldistributorifprolongedoperationatambient
temperatures above 100°F or below 40°F is unavoidable.
Location and Clearance
