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 contaminants
 A sight glass to observe the level of refrigerant
 A manual reset high pressure switch to protect the system from high pressures
 The unit uses only R-134a refrigerant
 A built-in condensate drain trap. (no external trap is required)
The Wine Guardian meets or exceeds its rated capacities for total BTU/H and CFM 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 that require no maintenance.
All exterior framing of the Wine Guardian is powder coated 0.063" 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.
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.
