2) A fan speed control may be used to adjust the air flow to achieve the
specified CFM. The fan will run from the minimum speed to full speed with the
control knob at the lowest and highest speed position. To adjust the minimum
speed, turn control knob to the lowest speed position, then rotate the setting
(located on the side or front) clockwise to decrease the minimum speed or
counter-clockwise to increase the minimum speed. The minimum speed
should be adjusted until it supplies the required CFM.

3) The subcooling at the condensing unit shall be around 10°F. The charge may
be complete when there are no more bubbles forming in the liquid indicator.
4) The head pressure shall be 120 ~ 150 psig at 70 ~ 90 °F condensing unit
operating temperatures.
5) The evaporator’s constant pressure expansion valve is set around 30 ~ 35
psig (35 ~ 40°F) at factory. This pressure setting gives a dew point to
maintain the proper humidity for storing wine.
6) The temperature split across the evaporator shall be 8 ~ 10°F at 55°F wine
cellar temperature.
7) Again, you must verify if the superheat at the evaporator unit is 9 ~ 18°F at
55 °F ~ 65 °F wine cellar temperatures.
