Preparation for use
Stationary cold water high pressure cleaner
The stationary wall-mounted systems are supplied with a stainless steel housing
and equipped with an AQ pump (W11/135 with APG pump) and 10m steel fabric
heavy duty hose.
Pressure fully adjustable, automatic total-stop feature.
After the gun is closed, the device continues to run for a time and then cuts out. It
restarts when the gun is opened. Incorrect operation by unauthorised persons is
therefore not possible. The factory setting is 30 seconds. The device is connected
to a water supply with advance pressure. Temperatures of up to 60 °C are possib-
le.
Features
Stainless steel housing,
10 m heavy duty hose with gun,
lance 800 mm
control nozzle and HP nozzle.
Preparation for use
Connect to suitable water supply, open the water tap.
Switch on high-pressure cleaner. The pump is running and the pressure is built
up. If the gun remains closed, the cleaner continues to run for another 30 seconds
and then switches automatically into standby.
As soon as you presser the trigger of the gun the high-pressure pump starts.
After closing the gun, it continues to run for approx. 30 seconds, and then
switches back to standby mode.
The device continues to run once the trigger is pressed during the 30 seconds.

Description
Water supply system
The water is fed under pressure (2 - 8 bar) to the HP pump. Then the water is fed
under pressure from the HP pump to the safety spray lance. The high pressure jet
is formed by the nozzle at the end of the lance.
The machine can only be operated when the safety trigger is squeezed.
When the lever is squeezed, the spray gun opens. The liquid is then pumped to
the nozzle.
When the trigger is released, the spray gun closes and any further spraying of
liquid from the lance is stopped and the manometer must show 0 bar.
The increase in pressure when the spray gun is closed causes the unloader
valve-safety valve to open. The pump remains switched on and continues to pump
liquid through the pump at reduced pressure. When the spray gun is opened, the
unloader valve - safety valve closes and the pump ressumes pressure spraying
from the lance.
The spray gun is a safety device. Repairs should only be perfor-
med by qualied persons. Should replacement parts be re-
quired, use only components authorized by the manufacturer.
Lance with spray gun
The unloader valve - safety valve protects the machine from a build up of excess
pressure, and is designed not to permit an excess pressure to be selected for
operation. The limit nut on the handle is sealed with a spray coating.
The operating pressure and spray rate can be steplessly adjusted by turning the
handle.
Replacements, repairs, new adjustments and sealing should only
be performed by qualied persons.
Unloader valve - safety valve
Environmental, refuse disposal and water protection
regulations must be observed !

Description

High pressure hose and spraying device
The high pressure hose and spraying device supplied with the machine are made
of high grade material. They are also optimized for the machine and marked as
required by the appropriate regulations.
If replacement parts are required, only such parts that are authorized
by the manufacturer and which bear the markings required by the ap-
propriate regulations may be used. The high pressure hose and spray-
ing device must be connected in a pressure-tight manner.
The high pressure hose may not be driven over, pulled excessively
or twisted. Make sure that the hose is not damaged on sharp edges.
Hose lines are wear parts. Guarantee is accepted only for manufactur-
ing errors, not for external damages.
High pressure hose lines and spraying equipment must not be
repaired, but replaced by a new hose or spraying equipment.
Unloader valve - safety valve
The unloader valve - safety valve protects the machine from a build up of excess
pressure, and is designed not to permit an excess pressure to be selected for
operation. The limit nut on the handle is sealed with a spray coating.
The operating pressure and spray rate can be steplessly adjusted by turning the
handle.
Replacements, repairs, new adjustments and sealing should only
be performed by qualied persons.
Take care that all screw connections are pressure-tight. A leakage
of gun, high-pressure hose or hose drum has to be repaired at once.
Leakages lead to an increased wear and to a possible malfunction
of the delayed motor cut-out.
Operator’s task:
Prior to each usage of this liquid spraying device, the operator is obliged to
check if all safety relevant parts are in perfect working condition.
(e.g. safty valves, high-pressure hose, cables and connections,
spraying devices, etc. )

Description
With delayed motor cut-out
Frequent, work-necessitated switching on and off of motors on
machines of this size puts a heavy load on the power network and
causes increased wear on internal electrical parts. That’s why the
motor on the new KRÄNZLE appliances switches itself off 30 seconds after the
trigger is released, and switches itself back on again when the trigger is pressed.
When running your high pressure cleaner with hot water of 60° C
raised temperatures occur. Do not touch the machine without safety
gloves!
CAUTION !
CAUTION !
Never use liquid containing solvents such as paint thinners, petrol, oil
or similar liquid matter. Pay attention to the instructions of the man-
ufacturers of the cleaning agents. The seals in the machine are not
resistant to solvents. The spray of solvents is inammable, explosive
and poisonous.
Setting up
Location
Neither set up and operate the machine in rooms where there is a risk
of re or explosion nor put it into puddles. Do not use the machine
under water.
Replacements and inspection work should only be performed by quali-
ed persons when the machine is disconnected from the power
supply, i.e. the plug is pulled out from the electrical socket.

Description
Electrical connection
The machine is supplied with an electrical power cord with plug.
The mains plug must be tted to a standard grounded socket with a
30mA residual current operated device. The socket must be protect-
ed with a 16A delay action fuse on the mains side.
KRÄNZLE W 11-135 = 230 Volt / 50 Hz
KRÄNZLE W 13-230 = 400 Volt / 50 Hz (phase-sequence not signicant)
KRÄNZLE W 15-200 = 400 Volt / 50 Hz (phase-sequence not signicant)
KRÄNZLE W 19-160 = 400 Volt / 50 Hz (phase-sequence not signicant)
When using an extension cable, this must have an earthed lead which is prop-
erly connected to the socket. The conductors in the extension cable must have a
minimum cross section of 1.5 mm². Plug connections must be of a spray-proof
design, and may not be located on a wet oor.
(with extension cables of more than 10 m - 2.5 mm2)
CAUTION !
The use of extension cables which are too long may lead to malfunctions and start
up difculty.

To shut down the pump:
Frost protection
Normally after operation, there is still some water in the device. Thus, you must take
special measures to protect the device from frost.
-Completely drain the device
For this purpose, separate the device from the water supply. Then, turn on the
main switch and open the gun. Now, the pump presses the remaining water out of
the water tank and the pump. However, do not allow the device to operate without
water for longer than one minute.
- Fill the device with antifreeze agent
If the device is not operated for longer periods, especially over the winter, you
should pump an antifreeze agent through the device. For this purpose, ll the anti-
freeze agent into the water box and turn on the device. Wait with opened gun,
until the agent spurts out of the nozzle.
However, the best way to protect the device from frost is
to store it at a frost-free location.

Safety Information
Important !!!
The machine must be disconnected from the power supply when ser-
vicing work is being carried out. The master switch should be in position
„0“ and the plug out of the socket.
Do not use the cleaner if electrical connections or other safety-relevant
parts (e.g. overpressure valve, high pressure hose, spraying equipment
etc.) are damaged.
The machine may only be used by persons who have received the neces-
sary training.
Never operate the machine without supervision.
The water spray can be dangerous. It should never be directed at people, animals,
electrical apparatus or the machine itself.
Never direct the spray at power sockets.
Parts of the machine interior and parts of the gun and lance become hot when hot water
is used. Leave the cover of the machine closed when using the machine and do not
touch the metallic parts of the gun and lance.
Children must not use high pressure cleaning equipment.
Do not damage the cable or repair it incorrectly.
Do not pull the high pressure hose if there are kinks or loops in it. Make sure that the hose
is not damaged on sharp edges.
Persons operating the machine should wear the necessary protective clothing, i.e., wa-
terproof clothing, rubber boots, safety goggles, headwear etc. It is prohibited to use the
machine in close vicinity to people lacking suitable protective clothing.
The high pressure spray can generate a high level of noise. If noise exceeds the maximum
allowed levels, users and others in the vicinity must wear suitable ear protection.
The high pressure spray causes recoil and additional twisting movement if the gun is angled.
The gun must therefore be held rmly with both hands. (see page 2)
Do not clamp down the trigger of the gun. Apply the safety catch after use, in order to
prevent accidental spraying.
Do not spray against matter containing asbestos or other hazardous substances.
Never spray liquids containing solvents, such as paint thinner, petrol, oil, or anything simi-
lar. Notethespecicationsoftheadditivemakers! The seals in the machine are not
resistant to solvents. The spray vapour of solvents is highly inammable, explosive and
poisonous.

The pressure
regulator
switches on
and off due
to pressure
loss!
Water can emerge at
these 3 points.
Check the seals and
replace the O-rings if necessary
or have the gun checked by the dealer.
Replace the O-Ring
at the lance or at the
HP hose respectively!
Reconnect
the hose, gun
and lance!
Problem
solved already!
Pull out the
power plug!

Small repairs -
The nozzle is blocked!
No water but the gauge shows full pressure !
18
Rinse the hose through
rst.
You should now have
a powerful stream of
water,
but if you
only get a few
drops from
the lance
remove the lance and clean
the nozzle.
Using the at spray lance
you only have to clean
the front nozzle.
Straighten a paper
clip and clean the
nozzle.
Insert pointed object
into the hole and pull
the cap back!
Check visually whether the
nozzle is clean. Now it works as well
as before.

do it yourself!
Nozzle dirty or sticky!
Pressure gauge does not show full pressure.
Water comes out in spurts.
If you do not use the high-pressure cleaner for some time the valves can stick.
The high-pressure
hose vibrates.
19
Straighten a
paper clip...
When a valve is blok-
ked, the gauge
shows little
pressure or
no pressure
at all,
or the high
pressure
hose
vibrates!
Open the valve
with a socket
wrench...
and remove the
valve screw, the
valve and the
o-ring.
Replace the rubber o-ring.and remove the
dirt from the valve
- the valve inside
must be closed.
Retighten the
