Cycling the Unit
The fans continue to free-wheel for several minutes when the unit cycles off. This is normal.
If the unit is furnished with a low ambient control, the condenser fan also cycles on and off during cooling. This
maintains the head pressure on the compressor under low ambient conditions, and is normal. The bottom of the
compressor stays warm even when the unit is off to keep the lubricating oil warm and separated from the
refrigerant.
Setting the Thermostat
Normal settings are between 54 and 58°F. If the optional heating coil is furnished, enter a separate
temperature setting to maintain the lower setting. To prevent the unit from short cycling, the setting
between heating and cooling cannot be closer than 3°F.
Regulating the Wine Cellar Temperature
Wine cellars have a natural temperature gradient of 5 to 10 0 between floor and ceiling. To increase or
decrease the temperature in various zones, change the air flow patterns.
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.
NOTE
To monitor the Cellar Temperature, place thermometers in various locations in the
cellar to monitor the temperature zones. Change the temperature in various zones by
shifting the air flow patterns.
Changing the Air Flow Direction
The grilles furnished with Wine Guardian are single directional.
Rotate the grilles to change the direction of the air flow.
When using multiple supply ductwork balance the air flow between the ductwork. If too much air flows though
one duct but not enough air flows from the other duct, install a damper or other restriction into the duct with too
much air. That will force more air to flow out the other duct.
