At a Glance Product at a Glance Product type Ducted airflow configuration kit Model number 03-DUCTED-KIT-LRG Included components 2 duct plenums Airflow configuration Fully ducted supply and return airflow Primary compatibility WhisperKOOL Blow-Through 4000 and Blow-Through 8000 evaporators Ductwork required Yes, for both supply and return airflow paths Cooling system included No Electrical connection required No Key Benefits Key Features Two-Plenum Airflow Configuration The kit includes one duct plenum for conditioned-air supply and one duct plenum for cellar-air return, creating a complete ducted airflow path between the evaporator and wine cellar. Supports Concealed Evaporator Placement Fully ducted airflow allows the evaporator to be positioned away from the visible cellar, subject to approved installation, airflow, ducting, ambient-condition, drainage, and service-access requirements. Compatible with Larger Blow-Through Evaporators Model 03-DUCTED-KIT-LRG is intended for compatible Blow-Through 4000 and Blow-Through 8000 evaporators. It is not the smaller ducted kit used with the Blow-Through Mini. Supports Remote Supply and Return Registers The plenums allow supply and return ductwork to terminate at separate cellar registers, supporting more discreet airflow distribution and reducing the visual presence of the cooling equipment. Passive Airflow Accessory The plenums do not require electrical wiring or refrigerant connections. They function as airflow connection components within the complete cooling-system installation. Best Applications Best Applications Mechanical-room evaporator installations Adjacent-room equipment placement Ceiling-mounted or attic installations Soffit installations with remote registers Custom wine rooms requiring concealed cooling equipment Glass-enclosed wine displays Built-in wine walls Projects where direct evaporator airflow is not practical Installations requiring separate supply and return register locations The complete installation must provide properly designed supply and return ductwork, adequate airflow, suitable insulation, condensate management, structural support, and service access. How It Works How the Ducted Configuration Works A fully ducted Blow-Through installation uses one plenum on each side of the evaporator: Return-air plenum: Connects the cellar return-air duct to the evaporator so warmer cellar air can be drawn into the cooling unit. Supply-air plenum: Connects the evaporator discharge to the supply duct so conditioned air can be delivered back into the wine cellar. Supply and return registers should be positioned to promote circulation throughout the cellar. The layout should help prevent conditioned air from immediately returning to the evaporator before it circulates through the conditioned space. Configuration Comparison Ducted vs. Ductless vs. Hybrid Airflow Kits Configuration Included Components Best Use Ducted 2 duct plenums Both supply and return air are routed through ductwork Ductless 2 airflow deflectors Both supply and return air move directly between the evaporator and cellar Hybrid 1 duct plenum and 1 airflow deflector One airflow path is ducted while the other uses direct airflow Select the airflow kit that matches the planned evaporator location and cellar airflow design.

Sold Separately Not Included Blow-Through evaporator Condensing unit Supply or return ductwork Duct insulation Duct collars, transitions, elbows, dampers, or fasteners Registers, grilles, or louvers Refrigerant line set Thermostat or controller Condensate drain materials Electrical components or field wiring Installation labor Installation Planning Installation Considerations The ducted airflow kit should be planned as part of the complete Blow-Through cooling-system installation. The evaporator, plenums, duct runs, registers, insulation, drainage, refrigerant piping, wiring, mounting structure, and service access should be coordinated before construction is completed. Confirm Supply and Return Orientation Determine the required supply and return orientation before mounting the evaporator or fabricating the duct system. The final arrangement should follow an approved Blow-Through configuration. Use Properly Sized Ductwork Undersized, overly long, sharply restricted, or poorly routed ductwork can increase static pressure and reduce airflow through the evaporator. Insulate and Seal Cellar-Side Ducts Supply and return ducts carrying cellar air should be properly insulated and sealed to reduce heat gain, limit air leakage, and help prevent condensation on exterior duct surfaces. Limit Restrictive Fittings Keep duct runs as short and direct as practical. Excessive elbows, abrupt transitions, compressed flexible duct, restrictive registers, and unnecessary length can reduce cooling performance. Preserve Service Access Do not permanently enclose the evaporator or plenums. The installation must preserve access to service panels, refrigerant connections, condensate components, wiring, controls, and removable equipment sections. Use a Qualified HVAC-R Technician A WhisperKOOL split cooling system must be installed and commissioned by a qualified HVAC-R technician. The airflow and duct design should be reviewed as part of the complete system installation. Ducting Guidance Ducting Best Practices Use appropriately sized ductwork for the required system airflow. Keep supply and return duct runs as short and direct as practical. Use smooth transitions rather than abrupt reductions. Limit unnecessary elbows and tight bends. Support flexible ductwork to prevent sagging or compression. Seal duct joints to reduce air leakage. Insulate ductwork exposed to warmer surrounding air. Protect insulation from moisture and physical damage. Keep registers clear of racks, bottles, cases, furniture, and decorative obstructions. Position supply and return registers to encourage circulation through the cellar. Airflow Requirements Register and Louver Requirements Decorative registers, grilles, and louvers must provide sufficient open free area for the cooling system. WhisperKOOL airflow guidance calls for approximately 50% to 65% open free area across the total register face. Register face dimensions alone do not determine usable airflow. Slat angle, blade spacing, decorative mesh, screens, backing material, finish coatings, and interior framing can significantly reduce actual free area. Restrictive ductwork or registers may contribute to: Reduced cooling output Higher operating noise Increased static pressure Reduced airflow Evaporator coil freezing Condensate-management problems Uneven cellar temperatures Reduced equipment life Technical Data Technical Specifications Manufacturer WhisperKOOL Product name 4000/8000 Ducted Airflow Kit Model 03-DUCTED-KIT-LRG Accessory type Blow-Through evaporator airflow configuration kit Configuration Fully ducted Quantity included 2 duct plenums Intended airflow paths 1 supply-air path and 1 return-air path Compatible series WhisperKOOL Blow-Through Series Compatible evaporator sizes Blow-Through 4000 and Blow-Through 8000 Cellar-side ductwork required Yes Cooling equipment included No Electrical connection None; passive airflow accessory Refrigerant connection None The supplied source materials do not provide separate published dimensions, weight, material, duct-connection diameter, or finish specifications for model 03-DUCTED-KIT-LRG.

The kit is intended for compatible WhisperKOOL Blow-Through 4000 and Blow-Through 8000 evaporator configurations. Is this kit compatible with the Blow-Through Mini? No. The Blow-Through Mini uses a smaller ducted airflow kit. Model 03-DUCTED-KIT-LRG is intended for the larger 4000 and 8000 evaporators. Is this airflow kit required? It is required when a compatible Blow-Through 4000 or Blow-Through 8000 evaporator will use a fully ducted supply and return airflow configuration. Does this kit include ductwork? No. It includes the two evaporator duct plenums only. The supply and return duct runs, fittings, insulation, supports, registers, and installation materials must be supplied separately. Does the kit include a cooling system? No. It is an airflow accessory only. A compatible Blow-Through evaporator and the appropriate condensing unit are required separately or as part of a complete system. What is the difference between the ducted and ductless kits? The ducted kit includes two plenums for connecting both airflow paths to ductwork. The ductless kit includes two airflow deflectors for direct airflow between the evaporator and cellar. What is the difference between the ducted and hybrid kits? The ducted kit uses two duct plenums. The hybrid kit uses one plenum and one airflow deflector, allowing one airflow path to be ducted while the other uses direct airflow. Can the evaporator be installed outside the wine cellar? A fully ducted configuration can allow the evaporator to be positioned in an adjacent or concealed space, provided the installation follows WhisperKOOL requirements for airflow, ducting, ambient conditions, drainage, mounting, and service access. Should the ductwork be insulated? Yes. Cellar-side supply and return ducts should be properly insulated and sealed when they pass through warmer spaces to reduce heat gain and help prevent exterior condensation. Can flexible ductwork be used? The duct design should follow WhisperKOOL guidance and be reviewed by the installing HVAC-R professional. Flexible duct must not be crushed, sharply bent, unsupported, or installed in a manner that restricts airflow. Why should duct runs be kept short? Longer duct runs and additional fittings increase airflow resistance. Excessive static pressure may reduce airflow, cooling performance, and temperature consistency. Can decorative registers be used? Yes, provided they offer sufficient open free area. WhisperKOOL guidance calls for approximately 50% to 65% open free area across the register face. Where should the supply and return registers be positioned? They should be positioned to encourage circulation through the wine cellar and prevent conditioned air from immediately returning to the return register. Final placement should be coordinated with the cellar layout and HVAC-R installer. Does ducting affect cooling performance? Yes. Duct length, diameter, insulation, fittings, register free area, air leakage, and static pressure can affect airflow and the performance of the complete cooling system. Does this accessory require electricity? No. The plenums are passive airflow components and do not require a separate electrical or refrigerant connection. Can I install the kit myself? The plenums are part of a split wine cellar cooling-system installation. Their orientation, duct connections, airflow, and surrounding construction should be coordinated with the qualified HVAC-R technician installing the complete system. Are the plenum dimensions published? The supplied product resources do not provide separate dimensions, weight, duct-connection size, material, or finish specifications for model 03-DUCTED-KIT-LRG. Compatibility should be confirmed by the accessory model and evaporator size.
