2. Electric Defrost- During an electric defrost we shut off the compressor and the Evaporator Fan Motor
but energize an electric heating element at which time the melting snowflake is illuminated.. The electric
defrost is intiated by time every eight hours on G-Series Refrigerators but then terminted when the
Evaporator Coil Temperture reaches 40 degress fahrenheit or a maximum of 25 minutes. After the
defrost heat is terminated a drip time begins during the drip time the coil temperature will continue to
rise until the two minutes of drip time is completed at which time the compresor is energized. Once the
Evaporator coil temperature drops to 30 degrees fahrenheit the Evaporator Fan Motor will be energized.
On G-Series Freezers Traulsen only uses one type of defrost.
Electric Defrost- During an electric defrost we shut off the compressor and the Evaporator Fan Motor but
energize an electric heating element at which time the melting snowflake is illuminated on the display. The
electric defrost is intiated by time every four hours on G-Series Freezers but then terminted when the
Evaporator Coil Temperture reaches 45 degress fahrenheit or a maximum of 30 minutes. After the defrost
heat is terminated a drip time begins during the drip time the coil temperature will continue to rise until the
four minutes of drip time is completed at which time the compresor is energized. Once the Evaporator coil
temperature drops to 35 degrees fahrenheit the Evaporator Fan Motor will be energized.
