    Heat Gain / Loss – The amount of cooling or heating expressed in BTUH and watts transferred between the wine cellar and the ambient space. The Wine Guardian must offset this heat/gain loss. Inlet Air – The air returning from the wine room to the Wine Guardian fan coil.

  • Page 8: Receiving, Inspecting And Unpacking The Wine Guardian Unit

    Wine Guardian Ductless Split System consists of two separate components, the Wine Guardian fan coil and condensing unit. Each Wine Guardian component is shipped in a corrugated box. A shipment may include one or more boxes containing accessories. ✓ Lift at the designated handhold locations only or fully support from underneath.

  • Page 9: General Description

    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 and plug.

  • Page 10: Wine Guardian Fan Coil Unit

    Wine Guardian Fan Coil Unit The Wine Guardian fan coil unit meets its rated capacities for total BTU/H and CFM (watts and M for 50Hz) at design cellar conditions and external static pressures. The fan is a motorized impeller type, statically and dynamically balanced, and uses permanently lubricated direct drive motors requiring no maintenance.

  • Page 11: Accessories And Optional Equipment

    Each humidifier is furnished with a communication cable connection to plug into the Wine Guardian fan coil unit. It is then controlled by the same user interface controller that is used for the operation of the Wine Guardian unit. The humidifier requires a water supply and drain for operation.

  • Page 12: Heater Option

    Heater Option The electric heat option includes an integral electric heating element, thermal overload protection device and controls. The Wine Guardian will either cool or heat the air, but it is not designed to do both at the same time.

    Following is a typical example of a Caution message as it could appear in the manual: CAUTION RISK OF PERSONAL INJURY OR DAMAGE TO EQUIPMENT Improper installation may result in the equipment malfunctioning and a safety hazard. Read all of the installation instructions before installing the Wine Guardian unit.

  • Page 21: Lockout/Tagout Procedure

    Lockout/Tagout Procedure 1) Turn off the power switch (indicator light should be off) 2) Unplug the unit from the electrical outlet and cover the outlet to prevent accidently plugging in the unit. 3) Turn off circuit breaker or disconnect switch at condensing unit. Safety Considerations The equipment covered by this manual is designed for safe and reliable operation when installed and operated within its designed specifications.

  • Page 22: Equipment Safety Interlocks

    Main Power Switch The main power switch is located on the front user interface of the Wine Guardian unit. It shuts off the power to the fan coil unit. A separate disconnect switch will be wired to the condensing unit.
  • Page 23 CAUTION • Clean only with a dry cloth. • Never pressurize equipment above specified test pressure. See Wine Guardian Specification sheet on page 10. • Do not use the Wine Guardian near water. • Do not block any supply or return air openings. Install in accordance with the instructions in this manual.

  • Page 25 ✓ Use only dedicated power outlet boxes of the correct capacity and configuration for the unit model. CAUTION RISK OF PERSONAL INJURY OR DAMAGE TO EQUIPMENT Improper installation may result in the equipment malfunctioning and a safety hazard. Read all installation instructions before installing the Wine Guardian unit.

  • Page 26: Installing The Fan Coil Unit

    Provide ample clearance around the unit to access for unit maintenance. 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 to a minimum.
  • Page 27 ✓ Where to locate the unit? Location is usually predicated by the racking that can be  reached for control panel access. ✓ How to mount the unit? Use the Wine Guardian supplied sleeve for through-the-wall  installation and our surface mount bracket for surface mount installations.

  • Page 28: Mounting The System

    IMPORTANT The Installation Sleeve must be installed level within the wall opening to provide proper operation of the Wine Guardian system. Failure to do so may result in improper drainage, excessive ware, vibration and noise.

  • Page 35: Leak Checking And Evacuation Process

    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 36: Refrigerant Charging – For Low Ambient Models Only

    Refrigerant Charging – for low ambient models only NOTE: The SS018 and WGS25 with low ambient option utilize a Headmaster control valve to control head pressure at low ambient applications, therefore require a specific initial charging procedure as outlined below.
  • Page 37 Charging of Systems with head pressure Control in temperatures below 70° F (21°C) (After normal evacuation procedures): NOTE: When charging in ambient below 70°F (21°C) the procedure is very critical. Be sure to adhere to the following steps. Failure to do so will result in overcharging the system.

  • Page 38: Superheat

    If you are not sure how to measure superheat or sub-cooling Superheat • Get an accurate suction line temperature on the suction line as close to the compressor inlet as possible. At same time, attach a compound pressure gauge set to the system so as to read the low side suction pressure at the suction service valve port (back seated valve stem to allow un- restricted refrigerant flow from evaporator back to the compressor).
