General Description
IMPORTANT
Design and specifications are subject to change without notice
View Fig. 1 and Fig. 2 on page 13 for details
The Wine Guardian cooling unit is a professional grade, American-manufactured, split two-piece
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 R-134a
refrigerant. The entire Wine Guardian fan coil section is tested at the factory and the condensing unit is
shipped separately. All components are of a high quality standard commercial grade. The entire system
is approved by ETL according to UL 1995 and CSA safety standards. All wiring complies with NEC.
Each Wine Guardian fan coil section is furnished with a sealed, UL-approved power cord and plug.
The Wine Guardian Ducted Split System Contains
1. A Wine Guardian Fan Coil Unit with:
A thermal expansion valve to control the flow of refrigerant into the evaporator coil
A built in condensate drain trap. No external trap is required.
A removable control panel for ease of service

Wine Guardian Fan Coil Unit
IMPORTANT
The air exhaust from the condensing unit is hot and will be 25 to 35 degrees F above the entering
temperature. The condensing units are rated for a maximum temperature of 115 degrees F. The
condensing units should be installed in a well-ventilated area to ensure proper air flow across the
condenser coil and to limit short cycling.
The Wine Guardian fan coil unit meets its rated capacities for total BTU/H and CFM at design cellar
conditions and external static pressures. The fan coil unit is capable of rated CFM against the static
pressure imposed by recommended ductwork. The fan is a motorized impeller type, statically and
dynamically balanced, and uses permanently lubricated direct drive motors requiring no maintenance.
The Wine Guardian fan coil section operates as 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 through one of five openings. Optional heating coils are located between the cooling
coil and the fan. These coils heat the air to prevent low temperatures in the cellar.
All exterior framing of the Wine Guardian is powder coated 0.063 inch gauge aluminum to prevent
rust and corrosion. All coils are copper tubes, aluminum fins, with an electrocoating to protect against
premature corrosion. 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. The fan coil has at least five
discharge outlets to facilitate custom installations.
Each unit is provided with a pre-wired and tested remote interface controller for remote mounting
within the wine cellar. The remote interface controller has multiple control functions for cooling,
heating and operation. It has a fully automatic mode to switch between heating and cooling.
Electrical Controls
The main electrical control board and components are located on a separate panel accessible through a side door
panel or by removal of the on/off panel from the system chassis.
All wiring is in accordance with the NEC.
Wires are numbered and color coded to match the wiring diagrams.
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.
Condensing Unit
Compressors are rotary, self-lubricating, permanently sealed, hermetic reciprocating-type compressors,
with internal overload protection and capacitor start. They include a minimum of 20 months
manufacturer’s warranty and an optional five-year warranty. Compressors are mounted on rubber-inshear isolators to reduce noise and vibration. Additional features include a liquid line filter drier,
Sporlan Head Master Controls, a liquid line receiver and refrigerant sight glass. Each unit is housed in
a painted steel enclosure suitable for outdoor installation. The outdoor enclosure has adequate area for
ventilation and refrigerant piping penetrations.

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.
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 25 foot length of round flexible duct and two straps. The number of duct
kits needed depends on the wine cellar layout and application. 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 – Standard on all Wine Guardian Ducted Split Systems
A factory-installed low ambient option is available that 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 compressor oil reservoir. The low ambient option is
recommended whenever the condenser section is exposed to air temperatures below 40
degrees F.
Condensate Pump
An optional Wine Guardian automatic condensate pump is available
remote sink, drain pipe or
outside. It requires a separate 120 volt electrical outlet.
to pump the water to a
Humidifier
Another popular option for the Wine Guardian is a humidifier. The humidifier is available for
split system installation and can be retrofitted onto any existing Wine Guardian unit. Each
humidifier is furnished with a communication cable connection to plug into the side of the
Wine Guardian fan coil unit. It is then controlled by the same remote interface controller that
is used for the operation of the Wine Guardian unit. The humidifier mounts directly onto the
Wine Guardian unit and requires a water supply and drain for operation.
CAREFULLY FOLLOW THE INSTALLATION INSTRUCTIONS INCLUDED WITH THE HUMIDIFIER.
REFER TO THE INSTRUCTIONS CONTAINED IN THE BOX FOR THE HUMIDISTAT.
