MAINTENANCE AND SERVICE
Integral jumper set in position A (Fig. 20A) means “extract” mode.
Intergal jumper set in position B (Fig. 20B) means “intake” mode.
The jumper position defines both the air-flow direction when the unit is activated for the
first time (for the synchronisation) and the air-flow direction of the free-cooling mode.
JUMPER POSITION
If two or more units are controlled by means of the same controller (149-SEN-CTRLS or
similar), they always operate in a synchronised way. Wiring diagram as per Fig. 18.
