Reducing Noise Generation; Ductwork - Wine Guardian D088 Installation, Operation And Maintenance Manual

Wall Mounting - If the unit is to be surface mounted on the wall, adequately support it
on both sides of the wall. Use floor or knee braces to transfer the load of the unit to
the floor or wall.
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 duct runs.

Reducing Noise Generation

Consider noise when locating the unit close to the cellar or to an adjacent occupied
space. The addition of 0.25" (6.35mm) thick rubber pads under the unit will 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
