Circulation fan
The heating system in your caravan has been fitted with a recirculation
air system(also referred to as the blown air fan) which distributes the
hot air throughout the entire interior by means of several air vents.
The air vents can be turned and opened individually, enabling the
hot air tobe distributed to where it is required.The desired heating
power can be regulated by using the fan control knob
k
. The fan
control
k
is located on top of the heater front cover.
The thermostat sensor is located at the bottom of the
heater. Please note that a cold draft will adversely affect
the thermostat. Such sources of interference must be
eliminated; otherwise, there is no guarantee that you will
be able to adjust the temperature to your satisfaction.
To start the fan, the heating system must either be con-
nected to a 230V power supply, or 12V via the camper's
battery should you be using a stand-alone power supply.
