8. How to adjust defrost cycle In case there is excessive frost, the parameters FnC = C-y, idF = 4 and MdF = 20 can be used to avoid frost. 9. How to adjust the humidity The parameter Fon is used to adjust the humidity in the wine cellar. Higher Fon results in higher relative humidity.
Care Guide In general, always unplug system or disconnect power while doing care. 1. Coil Cleaning • Clean the condenser coil regularly. Coil may need to be cleaned at least every 6 months. • Use a vacuum cleaner with an extended attachment to clean the coil when it is dusty or dirty.
