Component Overview - Wine Guardian SP25 Installation, Operation And Maintenance Manual

Component Overview

Cabinet – The cabinet (outer housing) is constructed of aluminum with a powder-coated
finish for corrosion protection.
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 – Cellar air is circulated through the evaporator section by another
blower, similar to the condensing section. 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. The electric heating coil, if ordered, is factory
installed between the evaporator coil and the blower and is complete with contactors
and limit controls.
Electrical Controls – Most of the electrical components and controls are in a separate
area accessible on the side of the unit. All wiring is in accordance with the NEC. Wires
are numbered and color coded to match the wiring diagrams.
Internal Drain Trap - Water condensate from the evaporator coil fills the trap and forms a
seal to prevent air from being drawn back through the drain tube. This allows the drain
pan to drain freely. No external trap is required.
Supply/Return Duct Collar – A composite-material, single-direction duct collar is
provided for both the inlet and outlet of the evaporator section. Two duct collars are
provided with the unit; every duct collar is interchangeable with access doors to control
and direct the airflow. These duct collars can be removed via the two quarter-turn
screws.
Refrigerant Circuit – The factory charged circuit includes a thermal expansion valve with
an external equalizer, sight glass with moisture indicator, a filter dryer, an automatic
low-pressure switch, and a manual reset high-pressure switch. For the Extreme Climate
Protection option, an automatic pressure switch controls the operation of the condenser
blower, and a heating element is added to the compressor oil reservoir.
Removable Panels – Insulated composite-material removable panels are provided on
the evaporator of the unit. These panels can be removed via the two quarter-turn
screws.
