The heating system in your camper has been
fitted with a recirculation air system which distri
-
butes 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
j
. The adjusting knob
j
is located on the
reflecting panel of the heater (Fig. 1 and 2).
If less air is circulated or the noise
from the blower increases, this
means that the ventilation wheel is
dirty. As a rule, the heating elment
casing and vacuum pipe should be
removed from the heating element
approximately every 500 hours of
operation and the ventilation wheel
should be gently cleaned with a thin
brush.
Always turn on the circulation fan
when you set the heater to positions
3, 4 or higher. Otherwise there is a
danger that the heater will overheat.
