    When performing maintenance, always use the Lockout/Tagout procedure, which is described in this chapter. Observe the maintenance safety guidelines in the Wine Guardian Manual. 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.

  • Page 5: Lockout/Tagout Procedure

    When receiving the unit, ensure the unit is undamaged and includes all ordered accessories. Note: Wine Guardian units are factory assembled and tested prior to shipment. Wine Guardian units are shipped in individual corrugated boxes. ✓ Lift only at the designated handhold locations or fully support from underneath. A shipment may include one or more boxes containing accessories.

    • Grille or Diffuser – Inlet or outlet plates to direct the airflow or protect the inside of the unit. • Heat Gain / Loss – The amount of cooling or heating expressed in watts transferred between the wine cellar and the ambient space. The Wine Guardian must offset this load.

  • Page 7: General Overview

    All wiring complies with NEC. Each Wine Guardian fan coil section is furnished with a sealed, UL-approved power cord and plug. All Wine Guardian 50Hz units carry the CE mark. Each unit is furnished with a sealed, CE-approved power cord.
  • Page 8 ✓ Low ambient refrigeration controls (see page 10 for Extreme Climate Protection option). The Wine Guardian Pro Split System models meets or exceeds its rated capacities for total BTU/H and CFM at design cellar conditions and external static pressures. Both the evaporator and condenser fans are capable of achieving the rated CFM against the external static pressure imposed by recommended ductwork.

  • Page 9: Accessories/Options

    Extreme Climate Protection This bundle includes both a factory-installed Low-Ambient-, and a factory-installed High- Ambient upgrade. Low-Ambient protection makes the Wine Guardian capable of exposure to low ambient temperatures. This feature controls the condenser fan operation based on head pressure and heats the oil reservoir, including a 3R Condenser Fan.
  • Page 10 Instructions. Duct Collar Kits Ductwork for the Wine Guardian system is sold in kits by size for each unit. Each kit contains two adapter collars, one 25-foot (7.3 meters) length of round flexible duct, and two straps. The number of duct kits needed depends on the installation layout. The size of the ductwork kit depends on the selected model of Wine Guardian system.

  • Page 11: Component Overview

    Component Overview Cabinet – The cabinet (outer housing) is constructed of aluminum with a powder-coated finish for corrosion protection. Condensing Section – Ambient air is circulated through the condenser section by a direct drive, permanently lubricated, motorized impeller blower. This section also contains the compressor and the electrical controls.

    Install Fan-Coil Floor Mounting - Mount the Wine Guardian fan coil on the floor but elevate it 4” (10cm) as a minimum on a frame with a plywood surface to keep it away from water. Allow adequate space for the external drain.

  • Page 21: Reducing Noise Generation

    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.

  • Page 22: Ductwork

    Ductwork Wine Guardian units are typically installed indoors near the wine cellar to minimize duct runs. Each unit is provided with one entering (or return) air inlet and five 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 ft (7.5 meter) is...

  • Page 24: Drain Line

    Do NOT install an external trap on the drain line, every ducted Wine Guardian unit is built with an internal trap. Allow enough height for the drain line to function properly. If draining into a nearby sink, the unit must be elevated higher than the rim of the sink in order for the water to drain by gravity.

  • Page 25: Installing The Condensing Unit

    Do NOT modify the plugs in any way. Do NOT use extension cords. Depending on the model, the electrical power supply must be either 115-volt or 230-volt AC, 1 phase, 60 cycle, and the electrical power cannot vary more than ±4% or damage may occur to the unit.

    Sample line Set Configurations Leak Checking and Evacuation Process • Pressurize and leak test the interconnecting lines, including the fan coil unit, fittings, and brazed joints using the intended operating refrigerant, nitrogen, or dry air for leak testing. A pressure equal to the low-side test pressure marked on the unit nameplate is recommended for leak testing.

  • Page 29: Start-Up

    Recommended Unit Minimum AWG SP25 Start-Up Prior to charging the system and start-up ensure the system has been powered for at least 24 hours. This is required so the compressor’s crankcase heater has ample time to warm the system to avoid premature failure.

  • Page 36: Maintenance

    Risk of Serious Injury Sharp Edges are present on the fan wheels, housing, fins, and coils Maintenance on Wine Guardian units requires working with high voltage and sheet metal with possible sharp edges. Only qualified personnel should perform maintenance. Some tasks require knowledge of mechanical and electrical methods. Make sure you are familiar with all hazards, general safety related procedures, and safety labels on the unit.

  • Page 37: Cleaning The Humidifier (Optional)

    Cleaning the Humidifier (Optional) If the unit was furnished with a humidifier, it requires periodic maintenance. Follow the instructions in the humidifier guide. Electric Heat The heating coil 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.

  • Page 38: Yearly

    Yearly (in addition to monthly) • Replace filters if worn or plugged beyond cleaning. • Check evaporator and condenser coils for dirt – use a vacuum with a brush attachment to clean the coils. • Clean condensate pan under the evaporator coil by flushing. Be careful to keep the drains pans clear of all debris.

  • Page 39: Troubleshooting

    Resetting the High-Pressure Switch High-Pressure Switch Has Shut Down the Unit 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.
