CHAPTER 1: GENERAL POINTS

1.1 INTEDED USE AND MODEL VERSION

The Fral Dehumidifier is intended exclusively for air Dehumidifier via a steam vapouration or a
ventilation unit approved by the manufacturer within the specified operating conditions. Any other
type of application without the express written consent of the manufacturer is considered as not
conforming to the intended purpose and may lead to Fral becoming dangerous.
Operation of the equipment in the intended manner requires that all the information in these
installation and operating instructions is observed (In particular the safety instruction).

FD series

FD 360

 Standard Version (mod. FD 360)
 Hot Gas Defrost (mod. FD 360/S)
 Hot gas Defrost + Electric Heatres (mod. FD360S+4kW)

Both models are also available in DEHU-CLIMA versions see other specific manual.
All models can be configured with in-line airflow or top airflow (see chapter 10).
