Performing A Pre-Installation Check; Locating The Unit; Grilles; Reducing Noise From The Unit - Wine Guardian Sentinel Series Installation, Operation And Maintenance Manual

Performing a Pre-installation Check

✓ Check for the proper installation of the electrical plug configuration.
✓ Check for the properly sized breaker.
✓ Is the cellar built with adequate insulation and vapor barriers?
✓ Are ducts installed above the ceiling or in accessible places properly sized before
being covered?
✓ Is enough space available around the unit for service and repair?

Locating the Unit

Wine Guardian units are typically installed indoors located near the 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 25 feet (7.5 meter) is recommended. If
longer runs are needed use more than one supply opening to reduce the airflow in each duct by
one half, or examine your duct run using our ductwork calculator

See Recommended Flexible Ductwork Sizing Chart on page 49.
Provide a three-foot (1 meter) clearance around the unit for removal of
grilles or ductwork, access to filters and unit maintenance. If the
humidifier is used, provide access space in front of it for service.

Grilles

One grille is provided on the condenser outlet. The grille is removable and can be replaced with
a duct collar should warm air need to be ducted away from the mounting area. 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 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 in a mechanical or storage type space. If exhaust
heat is undesirable, use duct collars and 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 (25 or 50mm) noise dampener between the unit and the wall absorbs and
reduces the 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 vibration transmission.
