CellarPro 1800XTSx series cooling units are self-contained and fully-charged. They are designed to be installed through an exterior wall.
1800XTSx wine cellar cooling units cannot be front or rear ducted. If you wish to rear duct an 1800 series unit to outside where temperatures will go below 40°F, choose the 1800XTS unit with rear ducting kit and compressor heating. Also include the fan cycling switch for temperatures that will go below 20°F.
On the cold side, this unit intakes from the front and exhausts cold air from the bottom (so the front 8 inches of the cooling unit must be inside the cellar.)
This unit requires fresh air intake at the rear and also exhausts from the rear.
If the fresh air intake (on the hot side) will pull air below 20°F, down to -20°F, you must add the fan cycling switch (see add-on options above).
This unit must always be installed and operated in an upright position.
