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, CEapproved 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.
Standard Specifications

IMPORTANT
Design and specifications are subject to change without notice
The Wine Guardian Unit Contains
A thermal expansion valve to control the flow of refrigerant into the evaporator coil
A filter dryer to keep the refrigerant clean and free of contaminant
A sight glass to observe the level of refrigerant
An automatic low pressure switch on the discharge to protect the compressor form high
pressures
The unit uses only environmentally friendly refrigerant F-134a
A built-in condensate drain trap. No external trap is required.
The Wine Guardian meets or exceeds its rated capacities for total watts and cubic litres per second at
design cellar conditions and external static pressures. Both the evaporator and condenser fans are
capable of rated CFM against the external static pressure imposed by recommended ductwork. Both
fans are motorized impeller plug fans, statically and dynamically balanced, and use permanently
lubricated direct drive motors requiring no maintenance.
All exterior framing of the Wine Guardian is powder coated 1.6mm gauge aluminum to prevent rust
and corrosion. All coils are copper tubes with aluminum fins. The unit uses an external drain to
remove excess moisture and not reintroduce it into the cellar or ambient space. Removable, multiple
access doors are provided to facilitate cleaning and maintenance, duct connections, and access to
components and wiring.
Both the evaporator and the condenser coils have pre-filters on the inlet to prevent dust and dirt from
fouling the coils, thereby reducing capacity. Each unit has at least three discharge outlets on both the
evaporator and the condenser coils to facilitate custom installations. Water-cooled units have copper
straight tube connections for both cooling water inlet and outlet.
Each unit is provided with a pre-wired and tested electronic digital thermostat for remote mounting in
the cellar. The thermostat has multiple control functions for the fans, cooling and heating. It has a
fully automatic mode to switch between heating and cooling.
Compressors are rotary, self-lubricating, permanently sealed, hermetic reciprocating type compressors, with internal overload protection and capacitor 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. All external controls are digital
and proprietary to Wine Guardian products. Only approved communication cable and Wine Guardian
controllers are suitable for proper system operation.

Accessories and Optional Equipment
Heating Coils
An optional heating coil is built-in and requires no additional power source. The electric heating
option is factory installed and includes primary and secondary over-temperature protection devices
per UL and NEC.
Water Cooled Option
A water cooled option is available that uses a tube-in-tube heat exchanger in place of the condenser
coil and fan. Waste heat from the refrigerant is transferred to the water. A two-way control valve is
used to regulate the flow of water to maintain head pressure.
Duct Collars and Flexible Ducts
Ducting for the Wine Guardian is sold in kits by size for each unit. Each kit contains two adapter
collars, one 7.62 meter length of round flexible duct and two straps. The number of duct kits needed
depends on the layout. The size of the kit depends on the model Wine Guardian selected. Follow
installation instructions carefully. Poorly or incorrectly installed ducts can degrade the performance
of your unit dramatically.
Extended Compressor Warranty
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 unit, it is recommended that you
purchase the extended warranty option.
Low Ambient Option
A factory installed Low Ambient option is available which makes the Wine Guardian capable of
exposure to low ambient temperatures. This feature controls the condenser fan operation based on
head pressure and heats the oil reservoir. The Low Ambient Option (LAO) is recommended
whenever the condenser section is exposed to air temperatures below 50°C. This can occur if the
unit is placed in a garage or under an outdoor canopy or if the unit is located inside a heated space
but the condenser air is ducted in from the outside.
Condensate Pump
An optional Wine Guardian automatic condensate pump is available
outside. It requires a separate 220/240 volt electrical outlet.
Humidifier and Humidistat
Another popular option for the Wine Guardian is a humidifier. It comes with a sheet metal adapter
box and a pre-wired humidistat. The humidifier is available for field installation and can be
retrofitted onto an existing unit. Each humidifier is furnished with an electronic digital humidistat
to control the humidity in the cellar. The humidifier mounts directly onto the Wine Guardian unit
and uses the common drain. The humidifier requires a water supply and no additional external
power.
CAREFULLY FOLLOW THE INSTALLATIONS INSTRUCTIONS INCLUDED WITH THE HUMIDIFIER. REFER TO THE IN-
STRUCTIONS CONTAINED IN THE BOX FOR THE HUMIDISTAT.
