Unsuitable fuels must not be
used as they can represent a
source of danger.
+
At temperatures below 8° C,
the fuel oil begins to solidify
(paraffin precipitation). This
can lead to difficulties in
starting the burner. Before the
winter period either add a
solidification point / flow
improver (available from the
fuel oil trade) to the fuel or
use winter diesel fuel.
ðFill the tank for the Alto
automatic scale alarm system.
"Alto Anti-Stone" prevents any
deposits of scale and acts at
the same time as a corrosion
inhibitor. Use the bottle
supplied with the pack for
filling (Fig. 4). For compatibili-
ty reasons, use only the tested
"Alto Anti-Stone". Order the
refill pack 6 x 1000 ml, No.
8466, in good time.
ðScrew the high-pressure hose
firmly onto the VarioPress
trigger gun1), pushing back the
slide of the locking pin (Fig. 5/
1 + 5/2).
ðSecurely tighten the screw of
the Roto-Fix high-pressure
spray lance, at the same time
pushing back the slide of the
locking pin (Fig. 5/3 + 5/4).
ðConnect the water hose (Fig. 6).
The use of a fabric-reinforced
water hose with a nominal
diameter of at least 1/2" (13
mm) is recommended.
ðConnect the high-pressure
hose to the high-pressure
connection. Ensure that the
union nut is securely tightened
(Fig. 7)!
ðTurn on the water tap.
ðInsert the plug of the cleaner
into the plug socket.
STARTING OPERATION
RTING OPERATION
+
The pipework of the machine
is filled with antifreeze.
Collect the first liquid (approx.
5 litres) which comes out of
the spray gun in a suitable
vessel for further use.
COLD WATER OPERATION
ðRelease the lock of the trigger
gun and press the trigger (Fig.8).
ðTurn the operating mode
switch to position .
-> The function test of the
displays on the operating
panel starts.
– All the indicator lights
come on briefly, then the
indicator light comes on
continuously to indicate
that the machine is ready
for operation.
ðOperate the trigger of the
trigger gun several times at
short intervals to bleed the
system.
HOT WATER OPERATION
ðSelect the temperature (20-
100° C).
ðRelease the lock of the trigger
gun and press the trigger (Fig.8).
ðTurn the operating mode
switch to position .
ðWhen a steady jet emerges
from the high-pressure nozzle,
turn the operating mode
switch to position .
Using a special device1), the
condensate coming out of the
heat exchanger can be collected
and disposed of in accordance
with the local sewage regulati-
ons; water poured in and emer-
ging at the nozzle then has the
same composition.
STEAM OPERATION
(OVER 100° C)1)
Replace the standard high-
pressure nozzle with the steam
spray nozzle (No. 6692)1). Set the
thermostat to a temperature of
above 100° C. Turn the rotary
knob on the safety control block
completely to the left (anticlock-
wise direction) (Fig. 9). Release
the lock of the trigger gun and
press the trigger. Turn the opera-
ting mode switch to position
When a steady jet emerges from
the steam spray nozzle, turn the
operating mode switch to positi-
on .
OPERATION OF THE ROTOFIX
HIGH-PRESSURE SPRAY LANCE
The RotoFix high-pressure spray
lance allows the spray lance to
be turned for pressure-free
operation:
ðPush back the slide of the
locking pin (Fig. 5).
ðTurn the screw fitting of the
RotoFix high-pressure spray
lance until the pin engages in
the next bore.
OPERATION OF THE COAXIAL
SPRAY LANCE1)
ðThe working pressure can be
steplessly varied by turning the
handle of the spray lance, but
with a constant volume of
water (Fig. 10).
OPERATION OF THE PRESSURE
AND WATER VOLUME
CONTROLLER
DX 845 W:
ðThe rotary knob on the safety
control block allows the
pressure and water volume to
be steplessly varied (Fig. 9).

Stepless variation of pressure and
water volume
ðContinuous operation =

control block (Fig. 9).
ðBrief operation = Rotary knob

(Fig. 11).
The set pressure can be read off
from the pressure gauge.
USE OF CLEANING AGENTS
ðPredilute cleaning agents as
described under "General"
and pour into the cleaning
agent tank.
ðSet the desired concentration
of the cleaning agent (table,
see section "General") at the
metering valve (Fig. 12).
ðSpray the object to be clea-
ned.
ðAllow the cleaning agent to
