The machine is equipped with a softener pump and softening tank (3 litres), they
are situated on the support plate above the high pressure pump.
These pump ensures that the softening product will be pumped to the coil of
the burner if the burner is put into operation (if there's a flame, this means when
fuel valve is opened). This is to prevent scale deposits to the coil of the burner.
See also the manual for operation of the dosage pump!
• Basic settings softener pump: turn the regulating screw to second position
(2th indication, see mark on the picture left -> 1 liter = 5h 5 mins.) at water
hardness of 20° F when using the DiBO recommended anti scale product
(3.8550.650).
• Softener pump range: 85 ml -> 600 ml/hour.

Depending on the scale deposits the pump may be put to the middle position (1
liter = 3h 55 mins.) Adjust the other settings experimentally according the local
hardness / application / cleaning temperature.
Attention: always set the softener pump
to position: on. Do not turn off!
The burner can still work approx. 2 hours before the PLC switches off the burner.
During these 2 hours, the reset button will start flashing (or display a message)
to indicate that the softening product is running dry. The softener pump will not
work at using cold water but jumps automatically on when the burner motor is
activated and the pump will work during xx sec. when the motor is deactivated!
The softener pump has also a run dry protection of the softening tank.
Consult, if necessary, the delivered safety data sheet (1.837.900) of
the softener product. Check the measures on exposure controls/
personal protection / first aid measures / firefighting measures.
