22. Softener pump (option)
The trailer is also equipped with a softener pump and softening tank (5 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 pic-
ture 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.
* Possible options:
Hardness (in °F)
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 acti-
vated 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.
