condenser coil and fan to remove heat from the refrigerant to the ambient air outside the wine
cellar. The word condenser refers to the condensation of the refrigerant from gas to liquid phase.
CE – Certificate of European conformity
Exhaust Air – The air leaving the evaporator or condenser section of the Wine Guardian unit.
Evaporator (Cooling) Section / Coil – The Evaporator Section uses the cooling coil and the
fan to remove heat from the air inside the wine cellar to the refrigerant, cooling the air and
condensing moisture out of the air. The word evaporator refers to the evaporation of the
refrigerant from liquid to gas phase in the coil. The Evaporator Section is connected to or inside
the wine cellar.
Heat Gain / Loss – The amount of cooling or heating expressed in watts transferred
between the wine cellar and the ambient space. The Wine Guardian must offset this load.
Inlet Air – The air entering the evaporator and condenser sections of the Wine
Guardian unit.
NEC – National Electrical Code
Recovery – The amount of cooling the unit does to return the cellar to its set point
temperature after some new load is introduced, such as people or new cases of warm wine
entering the cellar.
Return Air - The air leaving the cellar and returning to the inlet of the evaporator coil.
SP – Static pressure. Unit of measurement (inches of water column) of the pressure of the air
handled by the fan.

Factory-installed options
System accessories
If any items listed on the packing slip do not match your order information, contact the place
of purchase immediately.
Check the unit for:

General Description
The Through-the-Wall Wine Guardian 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. All 50Hz Wine Guardian equipment is CE certified.
Each system is factory installed with a sealed, CE-approved power cord and plug that can be
mounted on either end of the cooling system. Wine Guardian products are made in the USA.
The Wine Guardian Through-the-Wall 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 cellar 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 pressured and discharged out of the
system. The thermostat, located on the system, or through the optional 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 by an
optional condenser duct kit.

Wine Guardian Controls
Wine Guardian’s digital electronic control series offers a versatile solution for controlling and
monitoring your wine cellar temperature and humidity. This series consists of four controls; a
main control board; a local user interface; a remote user interface; and a remote temperature and
humidity sensor. The system only required the use of the main control board and one of the user
interfaces (local or remote) 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 local and 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 setting 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, an optional keypad lockout code, 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 user interface control will also employ an ON/OFF button that turns the system
on or off respectively.

All exterior framing of the Wine Guardian is powder coated, 0.063" gauge aluminum to prevent
rust and corrosion. All coils are copper tubes with aluminum fins. The evaporator is coated with
an “E” coat finish to prevent premature corrosion. The system uses an internal drain system to
remove excess moisture and does not reintroduce it back into the cellar. An auxiliary drain port
is located at the condenser end of the unit should there be a need to physically remove the
excessive moisture.
Each system is provided with a pre-wired and tested electronic digital thermostat (local user
interface) as standard, or an optional remote mounted thermostat (remote user interface) in the
wine cellar. The thermostat has multiple control functions for the fan, operation, cooling (if
equipped), and maintaining humidity.
Compressors are self-lubricating, permanently sealed, hermetic reciprocating type compressors,
with internal overload protection and capacity start with a minimum of one-year manufacturer’s
warranty and an optional five-year warranty. Compressors are mounted on rubber-in-shear
isolators to reduce noise and vibration.
Electric power is supplied by a single, factory-furnished cord and plug that can be connected on
the cellar side or the condenser side of the unit. Units are shipped from the factory with a plug
attached on the condenser side. All controls are 24-volt supplied from an internal transformer.

Accessories and Optional Equipment
Humidifier Connection: You can locate the low voltage connection for field
optional remote humidifier on side of control panel on the wine cellar side of
the WG cooling unit. The optional humidifier comes pre-wired to fit directly to
this connection for the WG unit to control cellar humidity level desired.
Installation Sleeve
Each Wine Guardian system includes an EasyMount™ installation sleeve to be used in the
mounting of the system through-the-wall at the desired location. The sleeve is essential for the
proper support of the Wine Guardian system and ease of installation. The maximum dimensions
of the wall opening should be 386mm wide by 413mm high.
For proper operation of the system, including drainage and undue noise and vibration, the
Installation Sleeve must be mounted level within the wall cutout and securely fastened to the
wall studs on either side of the sleeve as shown on page 18.
Extended
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.
