TABLE 3: OUTDOOR MEDIUM TEMPERATURE MODELSELECTRIC DEFROST | EZY SETTING=2
SET POINT IS 35° F
These models are intended for cooler applications and have electric defrost. These models are intended for coolers that
may be operated at a lower saturated suction temperature and require electric defrost to clear the coil.
TABLE 4: OUTDOOR MEDIUM TEMPERATURE MODELSAIR DEFROST | EZY SETTING=3
SET POINT IS 38° F
These models are intended for cooler applications and have air (O-cycle) defrost. The controller is pre-programmed for
4 defrost per day. These periods are reprogrammable.
