Venting - SOLAR
BOOSTER EH models
When the SOLAR BOOSTER
is properly connected to sup-
ply water, electrical installation
and a high pressure hose (or
pipeline) the high pressure
pump must be vented before it
is operational.
1. Turn on the water inlet and
wait until the water tank has
been fi lled with water.
2. Turn the main switch (2), to
position "ON".
3. Otherwise push the “START”
button (3), and the SOLAR
BOOSTER will start.
4. Open the outlet point - spray
handle on high pressure
hose, (d) or outlet on piping
system (e) without having a
spray lance connected.
5. Let the water run until all air
has escaped from the pump
(even water fl ow). If little or no
water fl ows from the system,
it may be necessary to vent
the internal feed pump sepa-
rately. The Nilfi sk-ALTO serv-
ice technician should perform
this by loosening the centre
screw on the feed pump, see
arrow.
6. In the case of a recently in-
stalled piping system, or if the
pipeline and the pump have
been emptied in any other
way, the system should be
vented by starting the pump
and then letting the water run
at each outlet point of the
pipeline at turns. It is recom-
mended to begin with most
distant outlet (height and/or
length).
7. When connecting the high
pressure hose directly to the
machine, starting the pump
and activating the trigger of
the spray handle without hav-
ing attached the spray lance
should vent the system.
8. Stop the SOLAR BOOSTER
by pressing the “STOP” push
button (4).
The SOLAR BOOSTER is now
vented.
