CAUTION!
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.
•
Fill the tank for the Wap
automatic scale alarm system.
"Wap Anti-Scale" prevents
any deposits of scale and acts
at the same time as a corrosi-
on inhibitor. Use the bottle
supplied with the pack for
filling
(Fig. 4)
. For compatibili-
ty reasons, use only the tested
"Wap Anti-Scale". Order the
refill pack 6 x 1000 ml, No.
8466, in good time.
•
Screw the high-pressure hose
firmly onto the VarioPress
trigger gun
1)
, pushing back the
slide of the locking pin
(Fig. 5/
1 + 5/2)
.
•
Securely 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)
.
•
Connect 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.
•
Connect the high-pressure
hose to the high-pressure
connection. Ensure that the
union nut is securely tightened
(Fig. 7)
!
•
Turn on the water tap.
•
Insert 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
•
Release the lock of the trigger
gun and press the trigger
(Fig.8)
.
•
Turn 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.
comes on continuously to
indicate that the machine
is ready for operation
flashes slowly (1x per
second), the plug socket
must be connected
correctly by an electrician
to change the direction of
rotation.
•
Operate the trigger of the
trigger gun several times at
short intervals to bleed the
system.
HOT WATER OPERATION
•
Select the temperature (20-
100° C).
•
Release the lock of the trigger
gun and press the trigger
(Fig.8)
.
•
Turn the operating mode
switch to position
.
•
When a steady jet emerges
from the high-pressure nozzle,
turn the operating mode
switch to position
.
Using a special device
1)
, 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:
• Push back the slide of the
locking pin
(Fig. 5)
.
• Turn the screw fitting of the
RotoFix high-pressure spray
lance until the pin engages in
the next bore.
OPERATION OF THE COAXIAL
SPRAY LANCE
1)
• The working pressure can be
steplessly varied by turning the
handle of the spray lance, but
with a constant volume of
water
(Fig. 10)
.

USE OF CLEANING AGENTS
•
Predilute cleaning agents as
described under "General"
and pour into the cleaning
agent tank.
•
Set the desired concentration
of the cleaning agent (table,
see section "General") at the
metering valve
(Fig. 12)
