Testing the Fan
Scroll through configurations settings to 17 for “On” or “Auto” operation. It is factory default to “Auto”.
•
ON means the fan runs continuously and indicates that the power is on and the
control circuit is energized and operating.
•
AUTO means the fan runs only when the thermostat is calling for cooling or humidi-
fication.
Running the System
√
Check system to confirm the compressor is running. When the compressor is on,
the system will blow cold air to the wine cellar and warm air from the condensor
section.
√
Check for any unusual noise or vibration, such as clanking or rubbing.
Important:
It is normal for the display to read a “high temperture” default alarm upon initial start-up while
trying to pull the wine cellar down to operating conditions as factory default is set at 60
0
F and its likely the cellar
may be above this condition upon initial start-up in a new application. The system will continue to cool until it
gets within 2 % +/- of the set point.
Initially, the system may run continuously for several hours, up to a day or more, while it lowers the cellar
temperature. Once the system reaches the set point temperature, it shuts off and starts to cycle on and off as
it continues to lower the cellar temperature to the set point. The cellar air reaches set point before the bottles.
If the cellar temperature started at 75
0
F, the supply air temperature discharged from the system will probably
be 15 to 20
0
F colder. As the cellar temperature decreases to 55
0
F, the supply temperature differential de-
creases 8 to 12
0
F colder.
Cycling the System
The fans continue to free-wheel for several minutes when the unit cycles off, if fan set to “auto” only. This is
normal.
Regulating the Wine Cellar Temperature
To keep the entire wine cellar at the same temperature, set the thermostat to run the supply fan continuously,
and not just when the cooling is operating. Set Fan switch to ON instead of AUTO.
Changing the Air Flow Direction
The grilles furnished with Wine Guardian are single directional, but the wine cellar airflow can be directed
horizontally manually by setting the louvers behind the plastic panel to desired direction. You must first remove
the 2 screws in the bottom of the plastic front to remove the front to gain access to turn the air directions as
desired.
