Design and specifications are subject to change without notice
The Wine Guardian Unit Contains
 A thermal expansion valve to control the flow of refrigerant into the evaporator coil
 A filter dryer to keep the refrigerant clean and free of contaminant
 A sight glass to observe the level of refrigerant
 An automatic low pressure switch on the discharge to protect the compressor form high
pressures
 The unit uses only environmentally friendly refrigerant F-134a
 A built-in condensate drain trap. No external trap is required.
The Wine Guardian meets or exceeds its rated capacities for total watts and cubic litres per second 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 permanently
lubricated direct drive motors requiring no maintenance.
All exterior framing of the Wine Guardian is powder coated 1.6mm gauge aluminum to prevent rust
and corrosion. All coils are copper tubes with aluminum fins. 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.
Both the evaporator and the condenser coils have pre-filters on the inlet to prevent dust and dirt from
fouling the coils, thereby reducing capacity. Each unit has at least three discharge outlets on both the
evaporator and the condenser coils to facilitate custom installations. Water-cooled units have copper
straight tube connections for both cooling water inlet and outlet.
Each unit is provided with a pre-wired and tested electronic digital thermostat for remote mounting in
the cellar. The thermostat has multiple control functions for the fans, cooling and heating. It has a
fully automatic mode to switch between heating and cooling.
Compressors are rotary, self-lubricating, permanently sealed, hermetic reciprocating type compres-
sors, with internal overload protection and capacitor start with a minimum of one-year manufacturer’s
warranty and an optional five-year warranty. Compressors are mounted on rubber-in-shear isolators to
reduce noise and vibration.
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.
