General Description
Refer to overview illustrations starting on page 12
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
R-134a refrigerant. The entire unit is tested at the factory and shipped as a single package. All
components are of a high quality, standard commercial grade. The entire unit is approved by ETL
according to UL 1995 and CSA safety standards. All wiring complies with NEC. Each unit is
furnished with a sealed, UL-approved power cord and plug.
The Wine Guardian unit is completely self-contained and includes either an integral air cooled 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 remotely mounted unit with external
ductwork connections.
Air first 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 setpoint. 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. The air
flows through the condenser coil where it absorbs heat from the refrigerant in the coil. The air is
then 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 on air-cooled units is hot and will be 25 to 35 degrees F
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.
