General Description

Refer to overview illustrations starting on page 12
The Wine Guardian PRO cooling units are professional grade, American manufactured, self-
contained climate control units designed specifically for the storage and preservation of wine, fur,
musical instruments, and data rooms and other specialty environments. They are designed for
easy installation and operation. Wine Guardian PRO uses R-134a refrigerant and the units are
tested at the factory and shipped as a single package. All components are of a high quality,
standard commercial grade. The entire units are 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 PRO systems come in horizontal models, are completely self-contained and
includes either an integral air cooled or water-cooled condenser .The units are 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 PRO units are 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.
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 ducted 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.
