electricity supply.

2.  Open the doors of the unit.

3.  Open the resistor box by undoing the mounting 

screws (10 PZ2 screws).

4.  Remove the quick connector of the resistor:

a.  Press down the locking device.
b.  Pull off the connector.

5.  Undo the two wing nuts connecting the resistor to 

the ventilation unit. 

6.  Lift the resistor out of the ventilation unit.

7.  To reassemble the ventilation unit, follow the above
