outside the cellar. Interior walls and floor should have a minimum of
R-11 insulation, and a vapor barrier on the warm side of the insulation. The
ceiling should have a minimum of R-19 insulation and a vapor barrier on
the warm side of the insulation. Doors also should be insulated and
tightly sealed with weather s t r i p p i n g a r o u n d t h e perimeter of the
door. Surface-mounted fixtures are recommended over recessed
lighting, which can allow air to leak into the cellar.
It is important that all walls, joints, doors and windows, electrical outlets
and/or switches, pipes, vents and light fixtures be sealed to prevent air and
moisture from entering the cellar. If there is a leak in the cellar, the cooling unit
will build up excess condensation.
CellarPro 3200 and 4200 cooling units are equipped with a condensate
management system, which includes a stainless steel pan, a
thermostatically-controlled electric heating element, and an overflow drain
at the rear of the cooling unit.
We strongly recommend that the overflow drain line (shipped loose with the
cooling unit) be connected to the overflow drain (as shown in the
installation section), and that the cooling unit be mounted to tilt slightly
backwards, so that any overflow condensate is channeled safely to the
overflow drain line. In addition, we recommend turning on the electric
heating element to burn off excess condensate that accumulates in the
stainless steel pan during the initial cooling of the cellar and during high run-
times, as well as in high-humidity environments.
 Fan Speeds
Your fan speed setting will need to be on “High” under the following
conditions:
- As the thermal load of the wine cellar increases
- As ambient temperatures increase
- As the static load from ducting (if any) increases due to factors
including the length of the duct run, turns, vent grills and/or reducers
 Ventilation
Adequate ventilation is critically important for the proper operation of your
CellarPro cooling unit.
