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.
Cooling Unit Runs Constantly
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. Raise the Minimum Set Point on the cooling unit
Cooling Unit 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 evaporated by the condensate heater.
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 overflow, 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. Ensure there is a downward pitch in the drain line from the outlet at the unit drain pan
to the final drain. It may be necessary to install a trap vent as detailed in the
Condensate Drain Line installation section.
3. Check that the cellar has airtight seals, including the door(s), light fixtures, and all
walls, ceiling and floor.
4. Raise the Minimum Set Point of the cooling unit.
The Cooling Unit
Won’t Turn On
The cooling system is programmed with a 3-Minute Delay at Startup to protect its
internal components.
