IV. Troubleshooting
Cooling Unit Runs Constantly
Improper installation, inadequate insulation, or a cellar that is too large will
cause the cooling unit to run continuously and cannot be troubleshooted.
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 14.4°C and the Temperature Differential is 2.2°C, the cooling unit will turn on
above 16.6°C and turn off below 14.4°C. In this example, the average temperature
inside the cellar will be 15.6 ° C.
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.
CellarPro 4200 Series cooling units are designed to maintain proper wine storage
temperatures inside cellars with adequate insulation up to 42 cubic meters.
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 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. Turn “on” the condensate evaporator switch.
2. Ensure the condensate overflow drain line is not blocked, that the drain
line is trapped and the trap is filled with water.
3. Make sure the unit is slightly tilted backwards to force condensate to flow
to the rear of the cooling unit.
