Wine Guardian Fan Coil Unit

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-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 steel enclosure suitable for outdoor installation. The outdoor enclosure has adequate area for
ventilation and refrigerant piping penetrations.
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.
