Starting the ventilation systemn
Setting the start direction of the reversing fan
In paired operation, one reversing fan is set in exhaust air direction, the other reversing fan is
set to supplyair direction. After the function test, the socket of the plug-in connection on the fan,
which is to start in supply air operation in pairs, must be turned.
TIP:
Note the starting direction of the respective unit in the connection plan. (Appendix 1) Thus
the starting direction is determined for upcoming maintenance tasks and a wrong connection will
be avoided.
Starting direction – Extract air:
•
The locking screws of the plug-in
connection's plug and socket are pointing
to the same direction.
Starting direction – Supply air:
•
The locking screws of the plug-in
connection's plug and socket are pointing
to different directions.
