Grilles
Grilles can be purchased as an option for installation inside the cellar or room. The return air, or
inlet, to the unit must connect to the return air outlet at the cellar or room. Any of the three supply air
outlets on the unit can be used for the ductwork to the supply grille inside the cellar or room. The
factory installed supply duct can be relocated to any of the other two openings. The procedures
below apply to both the evaporator and the condenser sections. In most cases, no ducts are installed
on the condenser section because the unit is located in a mechanical or storage type space. If exhaust
heat is undesirable, use ductwork to move the heat outdoors or to another space.
Reducing Noise from the Unit
Consider noise when locating the unit close to the cellar or an adjacent occupied space. A piece of 1
inch or two-inch dense rubber or Styrofoam with foil face in between the unit and the wall absorbs
and reduces the noise from the unit. For air noise use larger grilles or use flexible ductwork to absorb
the noise. Sound usually travels as a line of sight. Sound is reduced when it turns a corner, such as
passing through a bend in ductwork. If the unit is supported from a wall or joist, using a rubber pad
under the unit will reduce vibration transmission.
Installing the Unit Outdoors
The Wine Guardian PRO is NOT designed nor approved for direct outdoor installation. If it is
located outdoors, it MUST be protected with a rain-proof enclosure.
✓ Mount it above the ground on a solid, waterproof base to protect the unit from
ground water.
✓ Do not locate it where grass clippings or leaves can blow into the unit.
✓ Keep the area around the unit clean and free of debris.
✓ Protect from damage when the unit is located in a garage or unheated shed. In both
cases, the unit MUST have the low ambient controls built into the unit.
✓ Double insulating ducts with exterior grade insulation is recommended to keep the ducts
dry and effective. Wine Guardian suggests installing one sized flexible duct inside the
next larger size duct where ductwork is exposed.
✓ Allow enough space at both ends of the unit to remove ductwork and allow access for
service.
