1) Evacuate the system; both discharge and suction valves must be in the

middle positions during evacuating.

2) Charge the system through both suction and discharge valves with refrigerant

using the suggested amount; both discharge and suction valves must be in

the middle positions during charging.

3) Connect the power to start the system and check the following temperatures

and pressures.

9. Adjusting and Completing the Installation

1) 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.

2) Head pressure range: 125 ~ 150 psig at 70 ~ 90 °F condensing unit ambient

temperature.

3) 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.

4) The temperature split across the evaporator shall be 8 ~ 10°F at 55°F wine

cellar temperature.

5) Again, you must verify if the superheat at the evaporator unit is around 9 ~

18°F at 55 °F wine cellar temperature under high ~ low ambient temperatures.

6) If the superheat is high, check the subcooling first to know if the refrigerant

charge is sufficient. If the charge is not sufficient, add more refrigerant. If the

charge is good, then increase the evaporator suction pressure by turning the

hex nut (5/16”) clockwise. Liquid must always be charged into the hide side

when the compressor runs.

7) If the superheat is low, then decrease the evaporator suction pressure by

turning the hex nut (5/16”) counter-clockwise.

8) Both discharge and suction valves must be in the back positions before

disconnecting.

9) Close all service valves and disconnect all manifolds and hoses.
