Once the cooling unit is installed, all cracks and gaps between the cooling unit and
the cellar should be sealed. We provide butyl tape (shipped in the cavity of the
exhaust vent) for sealing these gaps. The butyl tape is pliable, and is designed to be
rolled and stretched in your hands to fit around the entire cooling unit. (If you adhere
the tape before rolling and stretching it, you will not have enough tape to complete
the job). Pay particular attention to the seams on the back of the cellar (top and rear
vent configurations) and the seams at the top of the cellar (top-vent configuration).
 Ventilation
WITHOUT DUCTING
Proper ventilation is critically important for the proper operation of your CellarPro
cooling unit. The CellarPro cooling unit blows a significant amount of hot air through
the top or the rear of the cooling unit, and the hot air must be exhausted into a space
that is at least as large as the wine cellar in order for the heat to properly dissipate.
If the space is too small or constrained, the heat will not dissipate and the cooling
unit will recirculate its own hot air, which will impair the cooling unit’s ability to create
cold air inside the cellar.
