Overview of the Wine Guardian Unit
Refer to illustrations on page 10
Cabinet – The cabinet is constructed of aluminum with a powder coated finish for corrosion
protection and an attractive, maintenance-free appearance. Areas in contact with cold
temperatures are lined with insulation to prevent condensation.
Condensing Section - Ambient air is circulated through the condenser section by a direct drive,
permanently lubricated, motorized impeller blower. This section also contains the compressor
and the electrical controls.
Evaporator Section – Wine cellar air is circulated through the evaporator section by a direct drive,
permanently or lubricated motorized impeller blower. The large evaporator coil face area
eliminates condensate carry-over, reduces air pressure drop and optimizes heat transfer. A drain
pan is located directly below the coil to capture condensate and is fabricated from aluminum to
prevent rust and corrosion.
Electrical Controls –All solid state electronic controls are connected internally and/or externally
through a phone cord-type connection. There is no need to open the chassis to access the factory
mounted and wired control. All internal wiring is in accordance with the National Electrical
Code. Wires are numbered and color coded to match the wiring diagrams.
Factory Tested – All Wine Guardian units are factory run-tested and checked for operational
performance.
Internal Drain – Condensate from the evaporator coil is directed to the condensate removal system
at the condenser end of the unit. This allows the drain pan to drain freely. No external trap is
required.
Refrigerant Circuit – The factory-charged circuit includes a capillary tube expansion device, a filter
dryer, and a manual reset high pressure switch. See Refrigeration Illustration on page 10.
Supply/return grilles
– These are made of rugged ABS plastic and factory mounted to automatically
seal to the chassis. Air is introduced through the sides and bottom and discharged through the
front perforated section.
Directional Louvers – Two directional louvers are located within the evaporator supply air dis-
charge opening on the Wine Guardian unit and can be accessed by removal of the wine cellar
side faceplate. The louvers are designed to be manually adjusted to direct air flow from side-to-
side or straight on. The louvers can help direct cold air into the center of the wine cellar should
the Through-the-Wall unit be mounted in a corner of the room.
