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 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.
• Possible options:

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.

Use the special spray lance when you work with steam (see picture)! Make sure
that the valve is set to 'high temperature function' and the throttle lever is also
put to position 'high temp function' when you work with high temperatures!
High temperature valve
The 'steam control' function is a function that allows to control pollution (weed)
using a hot water principle. The valve is located to the frame.
• Valve vertical: pressure washing activated (see symbol underneath - use the
appropriate lance).
• Valve horizontal: 'high temperature' function activated (see symbol
underneath use the appropriate lance). Mount the lances on the screw
coupling and snap into the holder (see picture left).
