Directory of Terms
AmbientAir – The surrounding area outside the cellar such as a room, basement, garage or outside.
BTU/H – British Thermal Unit per Hour is a unit of heat measurement. For example, one ton of cool-
ing equals 12,000 BTU/H.
CFM– Cubic feet per minute. Aunit of measurement for the amount of air handled by the fan.
Cellar – The wine storage area being conditioned by theWine Guardian unit.
Condensate / Condensation – The water formed out of the air when it is cooled below a certain
temperature (called dew point). Often referred to as “sweating” on pipes and cold surfaces. This
water collects at the bottom of the evaporator or cooling coil and drains out of the unit through the
drain line.
Condenser (heat rejection) Section / Coil – The Condenser Section uses the compressor, 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.
ExhaustAir – The air leaving the evaporator or condenser section of the Wine Guardian unit.
Evaporator(cooling)Section/Coil–TheEvaporatorSectionusesthecooling coil and the fan to remove

General Description
View the Overview Illustration on page 9 for details.
The Wine Guardian cooling unit is a professional, USA 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 environmen-
tally friendly R-134a refrigerant. The entire unit is run 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 CSAsafety standards.All wiring complies with
NEC. Each unit is furnished with a sealed, UL approved power cord and plug.
TheWine Guardian unit iscompletely self-contained and includes anintegral air or water cooled

IMPORTANT
The air exhaust from the condenser fan 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.

Design and specifications are subject to change without notice
The Wine Guardian Unit Contains
√ Athermal expansion valve to control the flow of refrigerant into the evaporator coil
√ Afilter dryer to keep the refrigerant clean and free of contaminants
√ Asightglass to observethelevelof refrigerant

√ TheunitusesonlyenvironmentallyfriendlyrefrigerantR-134a.
√ Abuilt-in condensate drain trap. No external trap is required.
The Wine Guardian meets or exceeds its rated capacities for total BTU/H and CFM 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 per-
manently lubricated direct drive motors requiring no maintenance.

Accessories and Optional Equipment
Heating Coils
Anoptional heating coil is built-inand requires no additional powersource.The electric heating option is
factoryinstalled and includesprimaryandsecondaryover temperature protectiondevicesperUL 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.Acontrol value 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 24ft. 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 modelWine Guardian selected. Follow installation instructions
carefully. Poorly or incorrectly installed ducts can degrade the performance of your unit dramatically.
Extended Compressor Warranty
TheWineGuardianusesonlythebestcommerciallyavailablecompressorsonthemarket.However,sincethe
compressor is the single most expensive component in the unit, it is recommended that you purchase the
extendedwarranty option.
Low Ambient Option
Afactory installed LowAmbient option is available which makes the 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 LowAmbient Option (LAO) is recommended whenever the condenser sec-
tion is exposed to air temperatures below 40°F. 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
Anoptional WineGuardianautomaticcondensatepumpisavailable topumpthewatertoasinkoroutside. It
requiresaseparate 115 volt electricaloutlet.
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 humid-

7
ityin the cellar.The humidifier mounts directlyonto theWineGuardian unit and uses the common drain.
The humidifier requires a HOT water supply and no additional external power.
CAUTION
CAREFULLY FOLLOW THE INSTALLATIONS INSTRUCTIONS INCLUDED WITH THE HUMIDIFIER. REFER TO THE IN-
STRUCTIONS CONTAINED IN THE BOX FOR THE HUMIDISTAT.

Overview of the Wine Guardian Unit
Refer to illustrations on page 9
Cabinet – The cabinet and access doors are constructed of aluminum with a powder coated
finish for corrosion protection and an attractive, maintenance free appearance.Areas in contact
with cold temperatures are lined with insulation to prevent condensation.
Condensing Section-Ambient air is circulated through the condenser section by a direct drive,
permanently lubricated, motorized impeller blower. This section also contains the compressor
and the electrical controls. If the water cooled option is purchased, a heat exchanger is used in
place of the condenser coil and blower.
Evaporator Section – Cellar air is circulated through the evaporator section by another blower
the same as above. The large evaporator coil face area eliminates condensate carry-over, re-
duces air pressure drop and optimizes heat transfer. A drain pan is located directly below the
coil to capture condensate and is fabricated from aluminum to prevent rust and corrosion. The
electric heating coil, if ordered, is factory installed between the evaporator coil and the blower,
and is complete with contactor(s) and limit controls.
ElectricalControls–Mostoftheelectricalcomponentsandcontrolsarelocated in a separate area
accessible through the condenser section.All wiring is in accordance with the National Electrical
Code.Wiresarenumberedandcolorcodedtomatch the wiring diagrams.
Factory Tested – All Wine Guardian units are factory run-tested and checked for operational
performance.
