Electrical Installation - Kärcher HWE 4000 Manual Original

Installing the plant
The plant may only be installed by authorised
technicians!
General
The heating appliance of the machine is an ignition plant.
–
Please follow the local regulations while installing it.
A main switch that can be locked is to be installed at a safe
–
and easily accessible place to switch off the entire heating
unit.
Use only certified chimneys/exhaust pipes.
–
Specifications, guidlines and regulations for installa-
The high pressure cleaning unit is subject to a commissioning
–
test according to the statutory requirements in the country of
installation.
(see "Installation certification/ Startup testing")
The high pressure unit is to be subjected to recurring tests ac-
–
cording to the statutory requirements in the country of instal-
lation. The test contents and the test frequency are to be
followed according to the pressure appliance directive DGRL
97/23/EG and the national regulations.
(see "Recurring tests")
Note: Please follow the national and local regulations for:
 Electrical installation
 Water installation
 Heating rooms
 Fluid spray jets (for high pressure cleaning units)
 Gas installation (in case of gas burners)

Electrical installation

Danger
Risk of injury on account of electric shock!
The electrical connections must be done by an electrician ac-
–
cording to IEC 60364-1.
The power supply designed for operating the plant must be
–
suitable for continuous operations.
Provide a emergency stop switch after fuse 1 x 10A (neutral).
–
 Install the emergency stop switch at the entrance door to the
heating room (see circuit plan).

Water installation
According to the applicable regulations, the appliance
must never be used on the drinking water supply without
a system separator. Use a suitable system separator
manufactured by KÄRCHER; or, as an alternative, a
system separator as per EN 12729 Type BA. Water flowing
through a system separator is considered non-drinkable.
Caution
Always connect the system separator to the water supply, never
directly to the appliance!
 Install stop-valves in the water inlets.
 Install a movable pressure hose between the connection to
the water supply network and the (high pressure) cleaning
unit.
 Design the water supply for continuous operations.
Install the high pressure/ hot water plant in a safe dry atmos-
–
phere and in a way that these can be accessed easily for re-
pairs and maintenance.
The ambient temperature must be below 40 °C.
–
Provide adequate space for maintenance and repairs jobs.
–
Provide water drainage for the safety valves and for the plant
–
during maintenance jobs.
Lay the exhaust pipe between the hot water generator and
–
the chimney in such a way that it is short and there is easy
flow.
Design the chimney cross-section according to the max. ther-
–
mal output.
Hang the general operating instructions in the heating room
–
so that they are easily visible.
If the design of the heating room is subject to "Heating room
guidelines", then you need to prepare an installation report with
the following contents:
Shortcomings in installing the danger switch, the main gas
–
shut-off system and the ventilation/ exhaust systems.
Results of the leakage tests in the boiler firing system.
–
Signature of the plant operator or his representative.
–
On continuous on-demand heaters, the safety valve must be
–
installed in the immediate vicinity of the boiler end.
The clearance between the connection pipe section and the
–
safety valve must be at least as large as the entry cross sec-
tion of the safety valve.
High pressure installation
Use only those installation materials that are permitted for use
–
for the expected operating pressure.
Install a movable high pressure hose between the building-
–
side high pressure pipe and the high pressure cleaning unit.
As far as possible, lay the high pressure pipes straight and
–
rinse them thoroughly before startup.
Provide for heat expansion and effects of pressure. Use
–
dead-beat loose and fixed clamps.
The pipes used for fuel supply (heating oil or gas) are to be
–
installed according to the applicable regulations.
