Safety devices serve for the protection of the user and
must not be put out of operation or bypassed with respect
to their function.
Overflow Valve With Two Pressure Switches
While reducing the water supply at the pump head or with
the Servopress - regulation the overflow valve opens and
part of the water flows back to the pump suck side.
If the hand-spray gun is closed, so that the whole water
flows back to the pump suck side, the pressure switch at
the overflow valve shuts down the pump.
If the hand spray gun is opened, the pressure switch on
the cylinder head turns the pump back on.
Safety Valve
The safety valve opens, when the overflow valve resp. the
pressure switch is broken.
The safety valve is set by the manufacturer and sealed.
Setting only by customer service.
ASSEMBLY & INSTALLATION INSTRUCTIONS
ASSEMBLY
Unpacking
Unpack carefully. Wear safety glasses or goggles while
unpacking, assembling or operating pressure washer.
If there are missing components or hidden damage
immediately contact distributor or carrier concerning
discrepancies.
1. Cut strapping band from pressure washer and pallet.
2. Remove pressure washer from pallet.
Check the contents of the pack before unpacking.
For scope of delivery see page 7.
INSTALLATION
Getting Started
IMPORTANT: Proper initial installation of equipment
will assure more satisfactory performance, longer
service life and lower maintenance cost.
WARNING: If connection is made to a potable water
system, the system shall be protected against back-
flow.
The pressure washer should be run on a level surface
where it is not readily influenced by outside sources
such as strong winds, freezing temperatures, rain, etc.
The pressure washer should be located to assure easy
access for filling of fluids, adjustments and maintenance.
Normal precautions should be taken by the operator to
prevent moisture from reaching the pressure washer. It is
recommended that a partition be made between the wash
area and the pressure washer to prevent direct spray from
the wand coming in contact with the pressure washer.
SAFETY DEVICES
Water Shortage Safeguard
The water shortage safeguard prevents the burner to be
turned on when there is water shortage and thus protects
the heat exchanger from overheating.
The lack of water fuse is a safety component and therefore
its locking screw is sealed.
The lack of water fuse functions immediately. It switches the
burner off immediately in case of insufficient water volume
and back on after the water level has been replenished.
The dry run protection is initiated when the lack of water
fuse signals insufficient water volume for 2 minutes. The
appliance shuts off with a fault message and locks up.
The appliance can be started back up by switching it off
and on via the program switch.
Temperature Stop For Exhaust Gases
The temperature stop switches off the machine when the
waste gases have reached very high temperatures.
Moisture reaching the equipment will reduce the pressure
washer's life. All installations should comply with the local
codes covering such installations.
Placement
Do not locate near any combustible material. Keep all
flammable material at least 20 feet away.
Allow enough space for servicing the machine.
Local code will require certain distances from floor and
walls. (Two feet away from walls should be adequate).
Venting
CAUTION: All venting must be in accordance with ap-
plicable federal and state laws, and local ordinances.
Consult local heating contractors.
If the pressure washer is to be used in an enclosed area,
a flue must be installed to vent burner exhaust to the
outside atmosphere. Exhaust gases should not be vented
into a wall, a ceiling, or a concealed space of a building.
Be sure the flue is the same size as the burner exhaust
vent on the pressure washer lid. Poor draft will cause the
pressure washer to soot and not operate properly. When
selecting the location for installation, beware of poorly
ventilated locations or areas where exhaust fans may
cause an insufficient supply of oxygen. Proper combustion
can only be obtained when there is a sufficient supply of
oxygen available for the amount of fuel being burned. If it is
necessary to install the machine in a poorly ventilated area,
outside fresh air may have to be piped to the burner and a
fan installed to bring sufficient air into the machine. Locate
the pressure washer so that the flue will be as straight as
possible and protrude through the roof at a proper height
and location to provide adequate draft.
