! CAUTION
To clean the boiler, only use Citrocal supplied by Nilo. Use 2 bottles of Citrocal for each
cleaning cycle and add water till the load pipe is full.
BED HEIGHT ADJUSTMENT FUNCTION
The bed lifts by pressing the SU (UP) key.
When the key is pressed, a consent signal is sent to the engine control unit for 15 seconds and the relevant
key is backlit blue for the same time. This happens even if the bed is already in its highest position.
The bed movement can be stopped by pressing the SU (UP) key again. Backlighting goes back to white.
Pressing the GIÙ (DOWN) key reverse the bed movement (and the associated actions on backlighting and
consent signals to the engine control unit).
The bed lowering function is similar.
The bed movement is not disabled during the boiler cleaning cycle.
