General Conditions
 Cooling Unit Runs Constantly
Improper installation, inadequate insulation, or a cellar that is too large will
cause the cooling unit to run continuously and be difficult to troubleshoot.
The cooling unit is designed to turn on when the air temperature in the cellar rises
ABOVE the Minimum Set Point + Temperature Differential, and turn off when the air
temperature falls below the Minimum Set Point. For example, if the Minimum Set
Point is 58°F and the Temperature Differential is 4°F, the cooling unit will turn above
62°F and turn off below 58° F. In this example, the average temperature inside the
cellar will be 60° F.
When bottles are first loaded in the cellar, the cooling unit will run continuously (even
up to a week) until the temperature inside the cellar falls below the Set Point.
Hot weather conditions, insufficient ventilation and/or dirty condenser filters may
cause the cooling unit to run continuously. To reduce cycle times,
1. Remove any obstructions to air flow to or from the unit
2. Check to make sure the condenser filter is clean
3. Increase the supply of cool air to the space outside the condenser coils, using a
fan, ducting or an exhaust system to remove heat from the space.
4. Raise the Minimum Set Point on the cooling unit
 Cooling Unit Is Producing Large Amounts of Condensate or is Dripping
The cooling unit is designed to remove excess moisture from inside the cellar, which
collects in the drip pan of the cooling unit and is channeled outside the cooling unit.
Excess moisture can occur when the cooling unit runs constantly, when the Minimum
Set Point is too low and/or when the cellar doesn’t have a good seal from the outside
environment. To eliminate excess condensation, do the following:
1. Ensure the condensate overflow drain line is not blocked, that the drain line is
trapped and the trap is filled with water.
2. Check that the cellar has airtight seals, including the door(s), light fixtures,
and all walls, ceiling and floor.
3. Raise the Minimum Set Point of the cooling unit.
4. Check to make sure the cellar has airtight seals, including the door(s), light
fixtures, and all walls, ceiling and floor.
