Installing the Fan Coil Unit
Wine Guardian fan coil 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 five possible supply air
outlets. A maximum cumulative total length of flexible ductwork, for both supply and return
ducts (including bends) of 8 meters is recommended. If longer runs are needed, use more than one
supply opening to reduce the airflow in each duct by one-half, or install rigid ductwork that is
typically less restrictive. Do not exceed 16 meters of total ductwork without using of booster fans.
See Recommended Flexible Ductwork Sizing Chart on page 33
.
Provide a three-foot clearance around the unit for removal of ductwork, or access for unit
maintenance. If the humidifier is used, provide access space in front of it for service. (See
separate humidifier manual.)
The fan coil unit can be located either above, or below the condensing unit in height. Wine
Guardian strongly suggests that any height difference be kept as minimal as possible.
The fan coil unit is equipped with an On/Off switch, two communication ports, and an optional
humidifier connection. One communication port is always used for the factory-supplied remote
interface controller and is supplied with 16 meters of communication cable. The second
communication port can be used for other factory options, such as remote temperature/humidity
sensors.
CAUTION
RISK OF PERSONAL INJURY OR DAMAGE TO EQUIPMENT
Check supporting structure for load bearing capacity to support the Wine Guardian.
All supports must be designed to meet applicable local codes and ordinances.
If in doubt, consult a qualified architect, engineer or contractor.
NOTE: Review Fig. 1 through Fig. 4 on the following pages before mounting the unit .
Floor Mounting
Mount the Wine Guardian fan coil on a plywood surface at least 30cm above the floor to
keep it away from water. Allow adequate space for the external drain.
Wall Mounting
If the unit is mounted onto a wall, provide adequate support on both ends of the unit to
accommodate the weight of the system. Use knee braces to transfer the load of the unit to the
wall. A shelf can be constructed to support the unit or a wall mount kit can be purchased
through a Wine Guardian distributor.
IMPORTANT
The fan coil unit is supplied with a plastic control box that houses a control relay/contactor.
The control box must be wired per supplied schematic to supply the 24 volt signal to
energize the condensing (outdoor) unit on a call for cooling. Mount this control box in the
most well protected location accessible to both the fan coil unit and condensing unit.
Mounting it directly inside the housing of the condensing unit is recommended, if the
installer concurs there is ample space to do so.
