Overview
(Refer to call-outs on Fig. 2.0)
Adapter plates – metal plates used to mount the humidifier to the different sizes of Wine
Guardian cooling units. Refer to Fig. 5 on page 16.
Humidifier Housing – the cabinet and access doors are constructed of ABS
(Acrylonitrile
Butadiene Styrene)
plastic. This provides corrosion protection and an attractive, maintenance-
free appearance.
Drip tray – the plastic water trough into which the water drips and is distributed evenly over the
drip pad through several holes evenly spaced in the trough.
Water drain connection – collects excess water at the bottom of the pad and is piped to an
external drain.
Electrical controls – most of the electrical components and controls are located inside the
humidifier enclosure. All wiring is done in accordance with the National Electrical Code. Wires
are numbered and color coded to match the wiring diagrams.
Drip pad – the expanded metal pad through which the cellar air flows and the water drips down
the surfaces.
Important: Black mark on pad indicates top.
Fan – turns "On" and "Off" on signal from the humidistat when humidity in the cellar is
required. The fan draws air across the evaporative drip pad to absorb moisture.
Front cover assembly – for freestanding applications only. Used to separate the inlet air from
the discharge air.
Orifice – small fitting with a very small hole in the center to restrict the flow of water. Refer to
Figure 8 on page 22.
Strainer – conical shaped stainless steel screen in a plastic frame to capture any sediment in the
water and keep it from plugging the orifice. Refer to Figure 8 on page 23.
Water solenoid valve – opens and closes to control the flow of water into the distribution trough
on signal from the humidistat. Refer to Figure 8 on page 23.
