Wine Guardian Wine Cellar Cooling Systems 50Hz (WG 175) - Manual (Page 7)

General Description
View the Overview Illustration on page 8 for details.
The Wine Guardian cooling unit is a professional grade American manufactured, self-contained
climate control unit designed specifically for the storage of wine at cellar temperatures. It is
designed for easy installation and operation. Wine Guardian uses digital electronic controls and
environmentally friendly R-134a refrigerant.
All Wine Guardian 50Hz units carry the CE mark. Each unit is furnished with a sealed, CE-
approved power cord and plug.
The Wine Guardian unit is completely self-contained and includes either an integral air or water
cooled condenser. The unit is functionally divided into two sections, the evaporator or cooling
section and the condenser or heat rejection section. Each section contains a coil to add or remove
heat and a fan to move the air through the coil and into or out of the cellar or adjacent space. The
Wine Guardian unit is designed to be used as a remote mounted unit with external ductwork
connections.
Air from the cellar first enters a filter to remove any airborne dust particles and then enters the
cooling coil. Air passes through the cooling coil and is cooled by the refrigerant inside the coil.
This causes any excess humidity in the air to condense and be captured in the drain pan and piped
outside the unit. Air then enters the fan where it is pressurized and discharged out of the unit.
Optional heating coils are located between the cooling coil and the fan. These coils heat the air to
prevent low temperatures in the cellar. The thermostat, located in the cellar, turns on the cooling
or heating as needed to maintain its set point. It does not allow the cooling and heating to be on at
the same time.
The compressor and condenser sections are activated whenever the unit is cooling. The condenser
fan draws air from the surrounding or ambient space either directly or through a duct. The air is
first drawn through a filter to remove any airborne dust particles to keep the coil clean. Then the
air flows through the condenser coil where it absorbs heat from the refrigerant in the coil. The air
is finally discharged out of the unit by the condenser fan.
The water-cooled Wine Guardian system requires cooling water to be piped to the unit for proper
operation. The cooling water absorbs the refrigerant heat through the unit’s water-cooled
condenser coil. Warm water is then directed out of the unit back to the cooling water system or to
a drain.
IMPORTANT
The air exhaust from the condenser fan is hot and will be 15 to 18 degrees C
above the entering temperature. This may cause overheating problems in the
summer months, especially with high humidity. Exhaust the hot air to the
outside. In the winter, this heated air can help to heat the surrounding space.
