This illustrates the air circulation system:
Fig. 3
The air circulation system consists of a direct driven fan and internal air passages
from the air inlet to the heated air outlet . The space heater can operate as a totally
external (fresh) air heater or in a recirculation mode utilising most of the air from the
heated space. In recirculation mode it is possible to run with up to 476 m3/h fresh air
by opening the round fresh air intake on the side of the unit.
Four air duct connections are provided, two on the supply discharge side and two on
the inlet/return airside .
The connectors are compatible with male spigots/connectors for 225 mm flexible ducts
which are fastened with rubber latches.
