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
√ An automatic low pressure switch to prevent low suction pressures and frost formation
on the coil
√ A manually reset high pressure switch on the discharge to protect the compressor from
high pressures
√ The unit uses only environmentally friendly refrigerant R-134a.
√ 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 per-
manently lubricated direct drive motors requiring 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 compo-
nents 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.
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 manufac-
turers 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 24 volt
supplied from an internal transformer. The 230 volt units are capable of operating at 208 or 240 volts
by changing the leads on the control transformer. See Wiring Diagrams .
