Reducing Noise Generation; Ductwork - Wine Guardian DP50 Installation, Operation And Maintenance Manual

Ceiling Mounting - Construct a structurally sound, level platform to place the unit on
when hanging it from the ceiling joists. The Wine Guardian system is NOT designed to
be suspended from the top of the unit; it must be supported from the bottom. Place the
unit on a platform to ensure that the unit is supported on all for corners. Leave
adequate space on the top of the unit to remove the access doors for service.

In all cases, the unit must be level to within ±0.25" (±6.35mm) end-to-end and ±1/8"
(±3.18mm) side-to-side for proper operation. Locate the unit as close to the wine cellar
as possible to reduce the length of the duct runs. If possible, use straight ducting on
all ductwork.

Reducing Noise Generation

Consider noise when locating the unit close to the cellar or to an adjacent occupied
space. The addition of 0.25in-thick (6.35mm-thick) rubber pads help prevent the
transmission of vibration and noise. A piece of 1" or 2" (25 or 50mm) noise dampener
between the unit and the wall absorbs and reduces the noise from the unit. For air
noise reduction, 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.

Ductwork

Wine Guardian units are typically installed indoors near the wine cellar to minimize the
duct runs. Each unit is provided with one entering or return air inlet and three possible
supply air outlets for each of the evaporator and condenser sections. A maximum
cumulative total length for both supply and return ducts (including bends) of 25ft (7.5m)
is recommended. If longer runs are needed, examine your duct run using our Ductwork
Calculator
