Reducing Noise Generation - Wine Guardian SP25 Installation, Operation And Maintenance Manual

Wall Mounting - If the Evaporator 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
Evaporator on when hanging it from the ceiling joists. The Wine Guardian fan coil 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 the unit is supported on all four corners.
Leave adequate space above 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 work.

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 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 noise from the unit. For air noise,
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 noise caused by vibration.
