Design and specifications are subject to change without notice

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

Themainelectricalcontrolboardandcomponentsarelocatedonaseparatepanelaccessiblethroughasidedoor

panelorbyremovaloftheon/offpanelfromthesystemchassis.

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 airexhaust from the condensing unit is hot and will be 25to 35 degrees F abovethe entering

temperature. The condensing units are rated for a maximum temperature of 115 degrees F. The

condensing units shouldbe installed in a well-ventilated area to ensureproperairflow across the

condenser coil and to limit short cycling.

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

to pump the water to a

remote sink, drain pipe or

outside. It requires aseparate120voltelectricaloutlet.

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.

CAUTION

CAREFULLY FOLLOW THE INSTALLATION INSTRUCTIONS INCLUDED WITH THE HUMIDIFIER.

REFER TO THE INSTRUCTIONS CONTAINED INTHE BOX FORTHE HUMIDISTAT.
