General Description
The Wine Guardian Cabinet cooling system is a professional grade, self-contained climate control
system 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. The entire system is run-tested at the factory and shipped as a single
package. All components are of a high quality standard commercial grade. The entire system is
approved by ETL (Equipment Testing Lab) according to UL (Underwriters Laboratory) 484 and
CSA (Canadian Standard Association) safety standards. All wiring complies with NEC (National
Electrical Code). All 50Hz Wine Guardian equipment is CE certified. Each system is factory
installed with a sealed, UL-approved power cord and plug. Wine Guardian products are made in
the USA.
The Wine Guardian Cabinet system is completely self-contained and includes an integral air
cooled condenser. The system 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 our or out of the cellar or adjacent space.
Air from the cabinet first 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 internally evaporates as it comes in contact with the integral
condensate removal coil. Air then enters the fan where it is pressurized and discharged out of the
system. The thermostat (remote interface controller) turns the cooling on and off as needed to
maintain its set point.
The compressor and condenser section are activated whenever the system is cooling. The
condenser fan draws air from the surrounding or ambient space. The airflows through the
condenser coil where it absorbs heat from the refrigerant in the coil. The air is finally discharged
out of the system by the condenser fan, and can be ducted outside or to an unused space through
optional duct collars.
CAUTI ON
THE AIR EXHAUST FORM THE CONDENSER FAN IS WARM AND CAN BE 20 DEGREES F
ABOVE THE ENTERING AIR TEMPERATURE.

Wine Guardian Controls
Wine Guardian’s digital electronic control system offers a versatile solution for controlling and
monitoring your cabinet temperature and humidity. This system consists of three controls; a main
control board; a remote user interface; and a remote temperature and humidity sensor. The system
only requires the use of the main control board and the remote user interface to function. However,
users have the following options to customize the control capabilities for their application: (See
pg. 8 for description of control boards and optional sensors).
The Wine Guardian’s digital electronic controls are designed to control the operation of the
compressor, condenser fan, evaporator fan, and optional humidifier. There also is pressure switch
monitoring with a dry contact alarm output that will energize in the event of a pressure switch fault
or a high/low temperature or humidity alarm. The remote user interface controls employ user-
friendly, menu-driven programming features that can easily be accessed by holding the mode
button on the control for five seconds. Once in the program menu, the user can scroll through the
settings by pressing the mode button and can adjust each setting by using the up and down arrows.
The programming mode allows the user to customize features such as °F or °C temperature scale,
high/low temperature and humidity alarm set points, an adjustable 0-10 minute compressor anti-
short cycle delay, sensor averaging options, enable or disable the defrost feature, differential and
dead band adjustments, room temperature calibration, enable or disable the humidifier, and
automatic or continuous fan option. To exit the programming mode the user may either hold the
mode button for 5 seconds or the control will automatically store the settings and exit the
programming mode after 10 seconds of inactivity. Each remote user interface control will also
employ an ON/OFF button that turns the system on or off respectively.

Accessories and Optional Equipment
Extended Compressor Warranty---U.S. and Canada only
The Wine Guardian uses only the best commercially available compressors on the market.
However, since the compressor is the single most expensive component in the system, it is
recommended that you purchase the extended, five-year warranty option.
Duct Collar Adapter
Optional duct collar adapters are available for ease in directing the warm condenser air away
from the cabinet or for directing cold conditioned air to the cabinet from the cooling unit.
Remote Temperature/Humidity Controller
The remote temperature/humidity controller (Remote Interface Controller) is intended to provide
a means for user interface at a remote location. The controller can be used as a remote
sensor/controller mounted within the cabinet. The controller can also be used as a remote indicator
(without sensor) mounted directly outside of the cabinet. The Remote Interface Controller includes
a backlit face for temperature and humidity indication along with controller set-up and operational
functions. Up to two (2) remote interface controllers can be used on one Wine Guardian Cabinet
unit.
Remote Temperature/ Humidity Sensor
The remote temperature/humidity sensor is intended to provide a means of sensing one or more
locations within the wine cellar and designed to work in conjunction with the Remote Interface
Controller or Local Interface Controller integral to the Wine Guardian Cabinet system. Multiple
sensor readings are averaged and controlled to a single point. The sensors do not have any
temperature or humidity indication and must be mounted within the cabinet.
Heater Option
The electric heat option includes an integral electric heating element, thermal overload protection
device and controls. The Wine Guardian will either cool or heat the air, but it is not designed to
do both at the same time. The Wine Guardian electric heat option must be specified at time of
order and installed at our factory.
