4328 SENSIBLE BTUH @ 55F.
CellarPro’s AH4500Si-ECX ducted cooling units (1/2 Ton Nominal) are engineered for wine cellars up to 1250* cubic feet in both commercial and residential wine cellars. This ducted unit uses 8-inch ducting and requires insulated ducting on the cold side.

This unit maintains optimal cellar temperature and humidity conditions in extreme conditions up to 110F. AH4500Si units use energy-efficient EC fans and are significantly quieter than comparable units from other brands. Visit our Learning Center for data tables, performance charts and product comparisons among different brands.

Our Compressor Heater (P/N 1727) is included to protect the compressor from in temperatures down to 20F. For installation of the condensing unit in environments below 20F down to -20F, our Fan Cycling Switch (P/N 6972) is a required addition, and Electronic Configuration is required.

*Assuming R19 insulation throughout the cellar, 55F inside the cellar and 85F outside the cellar. Cold-side ducting, glass and/or uninsulated walls, extreme humidity, altitude and other factors may affect the sizing calculation.

Our cooling units are designed to be used in properly-constructed wine cellars that are adequately insulated, airtight and sealed with a vapor barrier. In improperly-constructed cellars, the cooling unit will create excess condensation, leading to damage and premature failure of your cooling unit (not covered by warranty).

CONFIGURATIONS:

• CellarPro AH4500Si-ECX units are designed to be ducted, with the evaporator near (or inside) the cellar, and the condensing unit in a remote interior location up to 100 feet away.
• The evaporator and the condensing unit each can be ducted up to 100 Equivalent Feet (50 Feet per Duct) with 8-inch ducting .
• CellarPro’s split configuration allows multiple ducting alternatives, as follows.
  1. Collars or grills for EXHAUST (ie Supply) are located at the front (shown at left), top or rear of the cooling system, and are interchangeable to meet your specific requirement.
  2. Collars or grills for INTAKE (ie Return) are located at each end (left: evaporator, and right: condenser), and include professional-grade air filters to protect the unit.
• We recommend pulling the fresh air intake (hot-side) from a temperature-controlled environment (must be outside the cellar). If the hot-side exhaust will be directed to a different space than the intake, always make sure that both spaces are sufficiently voluminous so that you don’t run into issues with negative pressure.
• A bottle probe temperature sensor (10′ cord) plus your choice of duct collars, indoor grills and blank plates are included in the price of the cooling system.
• CellarPro Air Handler Split systems offer a choice of 110V / 60Hz wiring and power configurations:
  1. Two permanent power connections for the evaporator (2.0 amps / 15 amp circuit breaker) and the condensing unit (10.7amps / 15 amp circuit breaker). This wiring configuration is recommended for Valve Control.
  2. One permanent power connection for the entire system (15 amp circuit breaker). In this configuration, the condensing unit must be wired to the evaporator, and must be used with Electronic Control.
  3. The amp data above is not valid when the integrated heater and/or humidifier are configured with the cooling unit – please consult those Owner’s Manuals for the additional amps required when using those upgrades.
• When the control panel is difficult to access, we offer a remote control display kit which is wired to the cooling unit and allows the digital display to be mounted inside or outside the cellar.
• The condensing unit requires 12 inches of unobstructed space in front of the coils, and requires approx. 600-700 CFM of ventilation when installed in a confined space.
• For installations in environments below 40F, AH4500Si-ECX units require our Compressor Heater (P/N 1727) (included).
• For installation in environments below 20F down to -20F , Electronic Control is the required configuration, and our Fan-Cycling Switch (P/N 6972) is required in addition to the compressor heater (both sold separately).
• The evaporator should never be exposed to temperatures below 32F.
• Access to the left and right side of the evaporator unit is required for installation.
• All split systems must be installed and charged on site by a qualified HVAC professional. Line-set equivalent feet must be calculated in accordance with ASHRAE guidelines; refer to our Line Sizing Chart for more information.
• A CellarPro cooling unit must always be used in the upright position, and should never be operated on its side or upside down.
• We ship these units strapped to a pallet via common carrier with curbside delivery. Inside delivery is available for an additional charge.
• To activate your warranty, you must complete and return our Installation Checklist.
