Electrical Hazards Working on the equipment may involve exposure to dangerously high voltage. Make sure you are aware of the level of electrical hazard when working on the system.
Main Power Switch The main power switch is located on the side of the Wine Guardian unit. (See Overview Sketch on page 10 ) It shuts off the power to the unit. Energy Type Electrical Hazard........................Electrocution, electrical burns and shock Magnitude..................120 Vac and 230 Vac, 1 phase, 60 cycles Control Method...........Disconnect power cord and On/Off Switch DANGERS • Never reach into a unit while the fan is running.
CAUTIONS • Clean only with a dry cloth. • Never pressurize equipment above specified test pressure. See Wine Guardian Specification Sheet • 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 the Wine Guardian 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 Unit. Pre-installation Test Test the unit before installing it to check for non-visible shipping damage. To test the unit: √ Set the unit on the floor or a sturdy level surface √ Plug in the unit √ Turn on the rocker switch. The switch light comes on. This indicates the unit has power √ The built in timer prevents short cycling and keeps the unit from turning on right away.
WARNING 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, it may cause damage to the equipment and voids the warranty. √ Never place anything on top of the unit. √ Never block or cover any of the openings or outlets of the unit.
Planning the Installation Addressing Items in the Planning Process √ Where to locate the unit? Should it be built into the wall or mounted remote and ducted into the cellar. √ How to mount the unit? √ Decide where to locate the supply and return grilles in the room to achieve the temperature gradient and circulation preferred. √ Locate the electrical power outlet close to the unit.
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’ is recommended. If longer runs are needed use more than one supply opening to reduce the airflow in each duct by ½.
Installing the Unit Outdoors The Wine Guardian is NOT designed nor approved for direct outdoor installation. If it is located outdoors, it MUST be protected with a rain proof enclosure. • Mount it above the ground on a solid, waterproof base to protect the unit from ground water. • Do not locate it where grass clippings or leaves can blow into the unit. • Keep the area around the unit clean and free of debris. • Protect from damage when the unit is located in a garage or unheated shed.
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. 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 +/- 1/4" end to end and +/- 1/8" side to side for proper operation.
Priming the Drain Trap The internal drain trap primes itself automatically once the unit has run for a period of time and after the unit cycles off. This is confirmed by water dripping from the drain. Wiring the 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 outlet to the plug provided on the Wine Guardian.
DO NOT: √ DO NOT MODIFY THE PLUGS IN ANY WAY! √ Do not use extension cords. IMPORTANT The electrical power supply must be either 115 volt or 230 volt AC 1 phase 60 cycle, depending on the model of the unit, and cannot vary more than +/- 4% or damage may occur to the unit. Plug the unit into the wall outlet. Gently pull on the plug to make sure it is tight. Electrical Plug Configuration Installing the Thermostat and Control Wiring Each Wine Guardian unit comes with a thermostat and 25’ of wiring.
Reinstalling the Wires 1) Realign color coded wires 2) Wrap each wire around the screw and tighten the screw. Adding Additional Wiring √ Splice onto the factory furnished wire √ Match the wire colors for continuity √ Insulate the splice with electrical tape on each wire CAUTION RISK OF DAMAGE TO EQUIPMENT Misconnected thermostat wiring results in improper operation and/or causes damage to the unit and thermostat.
Note installation setup number and setting changed from the factory settings. Setup Number 3 - Changed to 1 Setup Number 5 - Changed to 9 Setup Number 9 - Changed to 5 Setup Number 12 - Changed to 1 Wiring diagram Fig .6 applies (Conventional 1 heating/1 cooling system with one transformer) The thermostat can receive a battery to light the panel in case of a power failure. It serves no other purpose and is not required for operation or restart after a power failure.
Installing the Ductwork Use ductwork to connect the unit to the supply and return outlets in the wine cellar. Use only insulated ductwork to minimize cooling loses, prevent sweating, and to reduce noise. Use ductwork on the condenser section to redirect or absorb sound, to bring in outside air to the unit inlet, and/or to exhaust the hot air out of the ambient space. NOTE Do not exceed a total of 25’ for each length of ductwork run.
Uninsulated ducts and surfaces cause bare exposed metal surfaces to sweat, further degradation of the insulation and a loss of equipment cooling capacity. 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 90° 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.
Using Ductwork Cold Air to/from Wine Cellar √ Remove supply air grille or access door panels to install ductwork between the Wine Guardian unit and the cellar. √ Connect the supply air ductwork from the cellar to the Supply air outlets at the Wine Guardian Unit. √ Connect the return air ductwork from the cellar to the return air inlet at the Wine Guardian Unit. Warm Air to/from Condenser √ Connect ductwork on the condenser to direct heat and the air noise away from occupants.

Inspection and Start-up Checklists Receiving and Inspecting Unit received undamaged Unit received complete as ordered including accessories Handling and Installing Unit mounted on solid level surface Sufficient space allowed for access to unit and accessories Proper electrical service provided Hot water provided to humidifier Drain lines and trap installed properly Ductwork, fittings and grilles installed properly All cold duct surfaces insulated Low ambient control included if freezing
Starting-up and Operating the Wine Guardian Now that the installation is complete, it’s time to start the unit up. Check to make sure all ductwork and electrical connections are secure. Replace all panels which were removed during installation. Check that all of the openings in the unit are covered with either a blank panel, a ductwork connection or a grille. CAUTION Rick of personal injury. Cover all openings of the unit to prevent a hand or finger from access inside the unit.
Cycling the Unit The fans continue to free-wheel for several minutes when the unit cycles off. This is normal. If the unit is furnished with a low ambient control, 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 Filters The evaporator and condenser coils are provided with reusable, washable air filters. The filters protect the coils from becoming coated or plugged by dust. Frequency of cleaning the filters is based on the amount of dust or dirt generated in the cellar or basement. 1. Remove the grille or duct collar on the inlet end of the unit 2. Remove the filter covering the face the coil 3. Wash it under warm water 4. Shake off excess water 5.
Heating Coil Option It is located between the evaporator coil and blower inside the transition duct. It contains the heating element and high temperature limit switches. The heating coil is wired to work in conjunction with the thermostat. Since the thermostat prevents the heating and cooling circuits from being energized at the same time, no additional power wiring is needed. We do recommend using the auto mode on the thermostat so it can switch from heating to cooling automatically.
√ Clean condensate pan under the evaporator coil by flushing. Be careful to keep the drain pans clear of any and all debris. √ Inspect cabinet for corrosion or rusting – clean and paint √ Inspect for dirt buildup on or inside the unit. Clean unit by vacuuming or wiping it down.

Seal openings around doors (gasket and sweep) Humidity Too High When Unit is Running and Cooling Possible Cause Solution Too much moisture in cellar Poor vapor barrier installation Humidifier malfunction refer to the Humidifier instructions.
High Pressure Switch has Shut the Unit Down Every Wine Guardian unit has a manual reset high pressure switch in the refrigeration system. This switch shuts the compressor and condenser down if the head pressure in the system is too high. It is intended to protect the compressor. Restricted airflow through the condenser is the most common reason for the pressure to become too high. This can be caused by dust covering the filter or an obstruction blocking the airflow in the duct or grille.
Advanced Troubleshooting IMPORTANT THIS SECTION IS INTENDED FOR QUALIFIED REFRIGERATION SERVICE TECHNICIANS ONLY. THE TECHNICIAN SHOULD REPEAT ALL OF THE PREVIOUS TROUBLESHOOTING STEPS BEFORE TAKING ACTION ON THESE MORE TECHNICAL SOLUTIONS.
