The power cord attached to the control box must be disconnected from the power sources prior to working on any part of the electrical system.
CAUTION Clean only with a dry cloth. Never pressurize equipment above specified test pressure. See Wine Guardian Specification sheet on page 13. Do not use the Wine Guardian near water. Do not block any supply or return air register or duct. Install in accordance with the instructions in this manual. Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades with one wider than the other.
Installation CAUTION SHARP EDGES RISK OF SERIOUS INJURY Sharp edges are present inside the Wine Guardian system. Pre-installation Test Test the system before installing it to check for non-visible shipping damage. To test the Wine Guardian fan coil section: Set the system on the floor or a sturdy level surface. Plug in the system. Press the on/off switch to see if the control illuminates. This indicates the system has power.
RISK OF PERSONAL INJURY OR DAMAGE TO EQUIPMENT Modification to the equipment may cause injury or damage to the equipment . DANGER This equipment is heavy. Place the unit on the floor or on a level and stable surface that can support the full weight of the unit. Do not modify the equipment. Modifications may cause damage to the equipment and will void the warranty. Never place anything on top of the unit. Never block or cover any of the openings or outlets to the unit.
Planning the Installation IMPORTANT Installation of residential and commercial split systems must be performed by qualified service technicians with proper training in the installation, start up, service, and repair of these systems. Certification to handle refrigerants is also required.
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 25 feet is recommended.
Ceiling Mounting Construct a structurally sound, level platform to place the unit on when hanging it from the ceiling joists. The Wine Guardian is NOT designed to be suspended from the top of the unit; it must be supported from the bottom. Angle brackets are available as an option for these types of applications. Place the unit on a platform to ensure that the unit is supported on all four corners. Leave adequate space on the top of the unit to remove the access doors for service.
Rod Mount Fig.2 Shelf Mount Fig. 3 Optional ductwork connection on same wall Fig.
Installing the Ductwork and Grilles Duct Collars One inlet duct collar and one evaporator outlet are supplied with each fan coil unit as standard equipment from the factory. The duct collars are removable. The return air, or inlet duct collar must connect to the return air outlet from the wine cellar. Any of the five supply air outlets on the unit can be used for the ductwork to the supply grille(s) inside the wine cellar.
General Duct Recommendation Support the flexible duct often to prevent sags or bends. Stretch the duct to make for a smoother interior for less air resistance. For a 90 degree bend, insert a metal elbow inside the flexible duct to avoid crimping. Do not squeeze or reduce the inside diameter of the ducts. This restricts the airflow. Use short and straight ductwork.
Installing the Condensate Drain Connection The Wine Guardian unit provides dehumidification for the inside of the wine cellar. It cools the air down to the dew point corresponding to the temperature setpoint of the remote interface controller. If the vapor barrier of the wine cellar is poorly constructed or excess moisture is in the basement, the unit may remove excessive amounts of moisture from the wine cellar. The moisture appears in the condensate drain of the unit.
Wiring the Fan Coil Unit for Power DANGER ELECTRICAL SHOCK HAZARD RISK OF SERIOUS INJURY OR DEATH The electrical outlet and wiring installation must meet the national and local building codes. DO: Match the electrical wiring to the cord provided on the Wine Guardian. Provide dedicated circuit and wiring for the system. Match the wiring and breaker size to the rated load as shown on the serial plate and in this guide. See sample serial plate illustration below.
Installing the Condensing Unit Condensing units are factory assembled with a sheet metal outdoor hood for protection from the elements. A minimum of 12 inches is required around the perimeter of the condensing unit for proper airflow across the coil, and to provide an adequate discharge airflow path through the louver section. Any obstructions to this airflow will result in a decrease in performance, and possibly premature failure due to a buildup of high pressure within the system.
quarter inch, a vibration eliminator should be installed close to the motor compressor in a horizontal parallel to the compressor, crankshaft or in a vertical position 90 degrees to compressor crankshaft. NOTE: The suction line should be clamped near the inlet end of the vibration eliminator. The vibration eliminator is located between the clamp and the compressor.

Starting-up and Operating the Wine Guardian Split System Now that the installation is complete, check to make sure all ductwork and electrical connections are secure. Replace all panels that were removed during installation. Check that all of the openings in the unit are covered with a blank panel, a ductwork connection or a grille. CAUTION RISK OF PERSONAL INJURY COVER ALL OPENINGS OF THE UNIT TO PREVENT A HAND OR FINGER FROM ACCESS INSIDE THE UNIT. Turn on the Unit Plug in the unit.
Cycling the Unit The fans continue to free-wheel for several minutes when the unit cycles off. This is normal. The unit is furnished with a low ambient control so the condenser fan also cycles on and off during cooling. This maintains the head pressure on the compressor under low ambient conditions, and is normal. The bottom of the compressor stays warm even when the unit is off to keep the lubricating oil warm and separated from the refrigerant.
Maintenance General WARNING BEFORE PERFORMING MAINTENANCE ON THE UNIT, READ AND UNDERSTAND THE SAFETY INFORMATION CONTAINED WITHIN THE SAFETY CHAPTER OF THE WINE GUARDIAN MANUAL. DANGER HIGH VOLTAGE - RISK OF SERIOUS INJURY OR DEATH HIGH VOLTAGES ARE PRESENT IN THE CABINETS. TURN OFF ALL POWER. USE THE LOCKOUT/TAGOUT PROCEDURE BEFORE OPENING PANELS. CAUTION SHARP EDGES RISK OF SEROUS INJURY SHARP EDGES ARE PRESENT ON THE FAN WHEELS, HOUSING, FINS AND COILS.
Cleaning the Condensate Drain System The condensate drain system traps dust and dirt. Clean the drain system once a year. 1. Shut off the rocker switch and unplug the unit. 2. Remove the duct on the evaporator inlet. 3. Inspect the drain pan under the coil. 4. If drain pan appears soiled, pour some hot water mixed with liquid bleach (diluted solution) along the length of the pan to flush the dirt down the drain tube. 5. Continue this treatment until the drain appears clean and free of dirt. 6.
Maintenance Schedule Monthly (or quarterly depending on experience with individual cellar) Check and drain trap – clean if needed. Check for noise or vibration. Check for short-cycling of the unit – a turning on and off of the compressor unit more than eight times/hour.
