The SOLAR BOOSTER is
equipped with a heating source
(electrical, or diesel driven) to
heat the water.
The heating source can be
switched on or off at conveni-
ence by pushing the yellow
“Heating” push button (5). Push-
ing the button once will turn
on the lamp in the button and
switch ON the heating source.
Pushing the button again will
turn out the lamp in the button
and switch OFF the heating
source.
SOLAR BOOSTER will moni-
tor the water temperature and
regulate the heating source to
provide the preset temperature.
On EH-models, with heating
tanks on the suction side of the
high pressure pump, heating
will be performed independ-
ently of the spraying operation
- “Working mode” as well as
“Standby mode”. The tempera-
ture is controlled by a tempera-
ture sensor in the water tank.
Thus the water will always be
preheated to the desired value
– ready for use when the spray
handle is activated.
On D-models heating is per-
formed by a burner in a pressu-
rized boiler.
Heating is control-
led by a thermostat on the
outlet of the boiler when water
