•The evaporator’s constant pressure expansion valve is set around 38- 40°F at factory. This pressure setting gives a dew point to maintain the humidity for storing wine.

•The superheat at the evaporator unit shall be around 9-18°F under low and high load at 75°F ambient temperature.

•Low side pressure: 33 psig

•High side pressure: 130 -150 psig at 75 -90 °F ambient temperatures
