With our duct kit, CellarPro 1800 cooling units can be ducted up to 50 equivalent
feet per duct. When calculating equivalent feet, each 90 degree turn in the ducting
approximately equals 8’ of ducting. Be sure to use gradual turns to avoid restricting
airflow inside the ducting. Consult your HVAC professional for further information.
INSIDE THE CELLAR
CellarPro cooling units are designed to turn on when the temperature near the ceiling
inside the cellar exceeds the Minimum Set Point plus the Temperature Differential,
and turn off when the temperature inside the cellar drops below the Minimum Set
Point. The Minimum Set Point and Temperature Differential can be set according to
instructions in the following Chapter. For example, if the Minimum Set Point is 58°F
and the Temperature Differential is 4°F, the cooling unit will turn on when the
temperature inside the cellar rises above 62°F, and turn off when the temperature
falls below 58°F. In this example, the cellar temperature will average 60°F.
1. Evaporator Air Intake. The evaporator coils are located on the face of the cooling
unit behind the grill. CellarPro cooling units are designed to be mounted at the
highest point inside wine cellars, so that warm air – which rises – will be the first to
pass over the evaporator coils, which will remove the heat from the air. To ensure
proper airflow, a minimum of 3” of clearance is required in front of the cooling unit.
2. Evaporator Air Exhaust. Cold air is exhausted through the bottom of the cooling
unit. Because CellarPro cooling units are located at the highest point inside wine
cellars, the cold air will fall to the bottom of the cellar. To ensure proper airflow and
reduce temperature stratification inside the cellar, the space below the cold air
discharge should be clear of any obstructions, including wine bottles, wine racks, etc.
 Power Requirement
CellarPro 1800 cooling systems require a dedicated 15-amp circuit. We recommend
using a surge protector to protect the internal components in case of a power surge.
The cooling unit uses approximately 3 amps during its “on” cycle. The cooling unit
also offers a grounded 115V AC outlet, which is rated for 3 amps.
A number of variables, including the minimum set point, the temperature in the
ambient environment, the insulation of the cellar, and the thermal mass inside the
cellar, will affect the cooling unit’s runtime. It is normal for the cooling unit to run up
to 75 percent of the time in order to maintain proper conditions inside the cellar.
