1.4 USE
Reventon Group Farmer HCF heating devices are designed for heating or cooling
surfaces in which aggressive conditions prevail, i.e. high content of acids,
ammonia and high concentration of dust. However, heaters should not be used in
highly corrosive environments for aluminum, copper and steel. The devices
should also not be installed in rooms where they would be exposed to the high
humidity or direct water action, exceeding the fan's resistance to water
penetration (see IP protection degree).

between the heaters, as shown in the following figure.
3.1. GENERAL PRINCIPLES
the air stream supply. The figures below show the recommended distances
between the heater and building partitions:
b) in case of ceiling mounting
During installation, ensure a free air flow to the device and do not restrict
a)in case of wall mounting
In case of higher heat demand, more units can be installed in the room. In order
3.2. ROTATING MOUNTING BRACKET
