CellarPro 1800 cooling units are self-contained, fully-charged and ready for installation out of
the box. They are designed to be installed through-the-wall, and can operate in temperatures ranging
from 40 to 95 degrees Fahrenheit. With the addition of our optional factory-installed compressor
heater, these cooling units can operate in temperatures down to 20 degrees Fahrenheit.
Cooling Unit Selection
To select the best cooling unit for your cellar, start by gathering the following information:
1. The cubic feet of the cellar,
2. The R-Value of the insulation inside the ceiling and walls,
3. The ambient temperature outside the cellar (during the warmest time of the year), and
4. The desired temperature inside the wine cellar
Using this information, find the "thermal load" of your wine cellar in the accompanying chart.
For example, the thermal load of a 300 cubic foot wine cellar at 55 degrees with R-12 insulation
and 85 degree ambient temperatures is 1662 BTUH.
Then, select a cooling unit that will produce equal or greater BTUH than the thermal load.
The BTUH produced by each cooling unit is listed at the top of the accompanying chart.
The cooling unit is designed to fit into an opening in the wall that is slightly larger
than the cooling unit, ie 18"wx 10.5"h. The rear of the cooling unit slides into the
opening until it is flush with the outside wall, while the front of the cooling remains
inside the cellar at least 8 inches. The rear of the cooling unit should be supported
by framing in the wall, while the front of the cooling unit can be supported in a variety of ways.
For example, a shelf and brace can support the bottom of the cooling unit inside the cellar. Another
option is to use mounting clips (sold separately) that attach to the top of the cooling unit. Mounting
clips must be bolted to framing in or above the ceiling, because unframed drywall is not strong
enough to support the weight of the cooling unit. Once installed, any gaps should be sealed with
adhesive tape to create an airtight environment inside the cellar.
The rear of the cooling unit is designed to pull air from an indoor space. This
air passes over the condenser coils, picking up heat,and then is exhausted back
into the indoor space. Therefore, this indoor space must be large enough for the
hot air exhaust to dissipate, or else the indoor space will heat up and the cooling
unit will recirculate its own hot air.
A rule of thumb is that the indoor space should be the same size or larger that the wine
cellar to ensure that the hot air will dissipate properly. Only CellarPro Model 1800XTSx
can be exposed to outdoor spaces.
Optional Rear Duct Kit
We offer a rear duct kit that allows the rear intake and/or exhaust to be ducted
up to 50 equivalent feet per duct, for use when the indoor space isn't large enough
to properly dissipate the cooling unit's hot air exhaust. Using the duct kit, another
option is to install the cooling unit entirely inside the wine cellar, while ducting
the hot air intake and exhaust to a remote location outside the cellar.
The duct kit includes an auxiliary fan that can be placed anywhere in the ducting,
and wiring that provides switched power from the cooling unit to the auxiliary fan,
so that it cycles on and off with the cooling unit.
Other Modifications and Accessories
Our factory-installed compressor heaters will allow the cooling unit to operate in
temperatures down to 20 degrees.
We offer two drain lines, with and without a 100-watt
condensate evaporator, for wine cellar installations especially in high-humidity geographies.
We also offer a power cord modification that allows the cooling unit to be plugged into
an outlet inside (rather than outside) the wine cellar. We offer professional-grade air
filters that can be used to keep the condenser coils clean,
and louvered grills to cover both the front and the rear of the cooling unit.
