CONDENSATION ON GLASS DOORS

Glass door refrigerators use two-pane

reflective, non-heated glass (NHG).

Condensation will form on the glass if the unit

is installed in a high humidity area.

Atmospheric conditions vary depending on

specific operating conditions. Use the chart

below as a guideline when selecting an

installation space.

Room Temperature Relative Humidity

70°F/21.1°C 76%

75°F/23.9°C 72%

80°F/26.7°C 69%

85°F/29.4°C 67%

90°F/32.2°C 65%

*Based on interior cabinet temperature of 38°F/3.3°C.
