Wine Guardian Fan Coil Unit
The Wine Guardian fan coil unit meets its rated capacities for total BTU/H and CFM (watts and M
3
/h
for 50Hz) at design cellar conditions and external static pressures. The fan coil unit is capable of rated
CFM (M
3
/h for 50Hz) 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 aluminum tubes, aluminum fins 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 (RJ-9) and Wine
Guardian controllers are suitable for proper system operation.
Condensing Unit
Compressors are self-lubricating, permanently sealed, hermetic reciprocating-type compressors, with
internal overload protection and capacitor start. The condensing unit includes a two-year warranty.
Compressors are mounted on rubber-in-shear 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 aluminum enclosure suitable for outdoor
installation. The outdoor enclosure has adequate area for ventilation and refrigerant piping penetrations.
All units come factory-configured with low-ambient protection for exposure to cold weather. This
feature controls the system pressures to prevent evaporator coil freezing (based on head pressure) and
heats the compressor coil reservoir
