How it Works:

The electronic control board on the Fral FDK54 dehumidifier is connected directly to the power outlet of the machine. It is equipped with three temperature probes and a humidistat. The electronic control unit, by means of the humidistat that measures the relative humidity in the environment, programs the machine to work to achieve the degree of relativity humidity desired. If the temperature of the finned coils drops too low, the electronic control unit starts a hot gas defrost cycle to melt the ice formed in the finned coils so that operation can resume.

Care of:

Every other month the removable filter should be examined for excessive build up. If the filter is visually dirty, remove the filter and rinse clean with water. Allow the filter to dry before reattaching to the dehumidifier.

Each year, during the late Fall once the outdoor temperatures consistently remain lower than the temperature in the space being dehumidified we recommend turning the dehumidifier off until warmer temperatures return in the Spring. For instance, in the Northeast most basements do not need a dehumidifier running after November 30th and can remain off until approximately April 30th. These dates will vary according to region but are a reasonable guide for operational need in most areas.
