Circulation fan
The heating system in your caravan has been tted with a recirculation
air system 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 to escape with the corresponding
intensity to where it is required. The desired heating power can be
regulated by using the adjusting knob
k
. The adjusting knob
k
is located on the reecting panel of the heater.
- The exact thermostat setting must be determined in accordance
with the oor plan and your personal comfort.
The thermostat sensor is located at the bottom of the
heater. Please note that a cold draft will adversely aect
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.
