Start-Up - Wine Guardian DP50 Installation, Operation And Maintenance Manual

Start-Up

• Check over the installation and ensure all wiring connections are correct
• Examine all duct connections, grilles, and panels in case any are not connected
• Start the unit
• Check ducts and duct connections for any possible air leaks
• Confirm condenser airflow is unrestricted
Now that the installation is complete plug in the unit. Turn-on the on/off switch on the
side of the unit. The on/off switch lights up to indicate power to the unit. The unit may
not turn on right away due to the timer built into the circuiting to prevent compressor
short cycling. The fan will only run when the system has a call for cooling which will
occur when the wine room's temperature is above the setpoint. Once the unit begins
cooling wait the allotted 5 minutes for the compressor to run. To check if the
compressor is running, check if cool air is leaving the evaporator or if you can hear a
humming noise from the compressor itself.
During the initial start-up, the unit may run continuously for several hours, up to a day or
more, while it lowers the cellar temperature. Once the unit reaches the set point
temperature, it shuts off and starts to cycle on and off as it continues to lower the bottle
temperature to the set point. The cellar air reaches the set point before the bottles. If the
cellar temperature started at 75 °F (24 °C), the supply air temperature discharged from
the unit will probably be 15 °F to 20 °F (-4 to -7 °C) colder. As the cellar temperature
decreases to 55 °F (13 °C), the supply temperature differential decreases 8 to 12 °F
(4.4 to 6.7°C) colder.
To decrease the run-time of the unit it is recommended to use a step down process. For
example, if you are aiming to hit a 55 degrees F setpoint then you would set an initial
set point of 63 degrees F. Once the system has reached 63 degrees F change the set
point to 60 degrees F, then 55 degrees F. Drop the setpoint in increments, so the
system has time to cycle instead of running continuously to reach the preferred set
point.
