NOTICE!
The clearance between adjustable clips should amount to at least 10 mm. The
following setting limits apply to the 3 possible series resistor types (see Tab. 6-
4).

Units of model size 7 are fitted with two series resistors.
It must be ensured that the set ohm value is twice as high for all resistor clips of
the side fan (see Fig. 6-3; Pos. 1) than for resistor clips of the middle fan (see
Fig. 6-3; Pos. 2).
DAMAGE TO THE UNIT!
It is not allowed to change speed on any of the series resistors (side or middle)!
Series resistors may burn through!
