when the room temperature is lower than set on the
thermostat, and it will stop again when the tem-
perature has reached the set value.
B. The fan breaker (4) is set on either „Auto" or „Man".
- If the fan breaker is set on „Auto" the fan is controlled
automatically by the combi thermostat in the unit. I.e.
when them temperature inside the unit has reached
50°C the fan will start automatically, and the unit has
been cooled down to about 30°C (burner stop) the fan
will stop automatically.
- If the fan breaker is set on „Man" the fan will run
continuously till it is set on „Auto".
3.2 Summer Operation
The burner breaker (5) is set on „0" and the fan
breaker (4) on „Man". In that way ventilation and thus
a comfortable summer temperature is obtained.
4. Service and Cleaning
4.1 Filter*
The air intake filter should be checked and, if
necessary, cleaned/renewed every 6 months. In very
dusty rooms it should be checked more often.
The filter is drawn out of the filter frame. If the filter is
only a little dirty it can be vacuum cleaned. If it is very
dirty it should be washed in luke warm soapy water or
perhaps be renewed.

4.2 Burner Chamber and Heat Exchanger
The heat exchanger and the burner chamber should

be cleaned at least once a year, as soot deposits can
reduce the efficiency of the unit.
Warm air heaters should be checked at least once
a year by a specialist! We recommend you to take
out a service service contract.
