Wine Guardian Wine Cellar Cooling Systems 50Hz (WG 175) - Manual (Page 44)

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 12 and 14°C. 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 2°C.
Regulating the Wine Cellar Temperature
Wine cellars have a natural temperature gradient of approximately 3°C 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.
