Grilles
Each of the inlets and one evaporator outlet and one condenser outlet come from the factory
with grilles over the openings. The grilles are removable. Remove the necessary grilles for
installing ductwork between the unit and the cellar. If desired, use the grilles as wall grilles
inside the cellar. The return air, or inlet, to the unit must connect to the return air outlet from
the cellar. Any of the three supply air outlets on the unit can be used for the ductwork to the
supply grille inside the cellar. The factory installed outlet grille 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 the grilles to
install ductwork to move the heat outdoors or to another space. Also, use ductwork to direct
condenser air noise away from occupants.
Reducing Noise from the Unit
Consider noise when locating the unit close to the cellar or an adjacent occupied space. A
piece of 25 or 50mm 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 better grilles or block the
noise with a solid piece of wood or Styrofoam. 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 is
NOT
designed nor approved for direct outdoor installation. If it is
located outdoors, it
MUST
be protected with a rain-proofed 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 the grilles or ductwork and
allow access to the filters.
