Summary
Keep in mind the following guidelines when selecting your wine cooling unit from
CellarPro:
If the cellar is too large for the cooling unit, the cooling unit will be unable to
maintain proper, even temperatures inside the cellar.
Without proper insulation and an airtight environment, the cooling unit effectively
will become a de-humidifier and potentially will produce buckets of water.
Without access to cool air, either because of improper ventilation or because the
environments is too hot, the cooling unit will be unable to maintain proper
temperatures inside the cellar.
When the cooling unit will be exposed to temperatures below 40°F, a
compressor heater must be added to protect the compressor.
Under any of the above conditions, the unit’s internal components may become
damaged, the expected useful life of the wine cooling unit may be adversely
affected, and the product’s warranty may become null and void.
