2.3
Installation and Operating Instruction
Mobile Hotwater High Pressure Cleaners
Etronic I/II - HDE-Series
Never aim the high pressure jet at fragile or loose objects.
When cleaning tyres and their valves, keep a minimum distance of 30 cm from
the high pressure nozzle. Otherwise damage may occur.
Before cleaning the high pressure cleaner itself, take the device out of operation and disconnect it from the electrical mains connection. Secure the device
against unintentional or unauthorised restarting (e.g. lock main switch, disconnect mains cable from power outlet, provide warning sign indicating work
on the high pressure cleaner, etc.).
Never operate the device unattended.
The device is designed for a water inlet temperature of up to 98 &deg;C or even
higher water vapour temperatures. When operated with hot water, watercarrying parts (for example pump housing, uninsulated pipes, metal parts of
the trigger gun and spray lance) as well as cleaning objects may become hot.
Touching hot surfaces can cause burns or scalding of the skin surface. Make
sure surfaces have cooled before touching.
The hot water escaping from the trigger gun must not come into contact with
the skin. After hot water operation, wait until the water has cooled down again.
Asbestos-containing and other materials containing substances hazardous to
health must not be sprayed off.
Information on hearing protection.
If the sound levels exceed the permissible values, the personnel and persons
in the area of exposure must wear hearing protection
2 Safety
The sound level for EHRLE high pressure cleaners under maximum load is
82 dB (A). A high sound level over a long period can cause hearing loss. If
the noise produced by the application of the emerging high pressure jet to
noise-enhancing objects exceeds the permissible values, the operating personnel and any persons affected must wear hearing protection.
Do not operate the device if electrical cables or other safety-relevant parts
(pressure relief valve, HP-Hose, trigger gun, etc.) are defective.
Before changing the cleaning agent, flush out the complete high pressure
system for minimum 2 minutes by pulled trigger gun. This avoids subsequent
dangerous chemical reactions
Generally, Mobile High Pressure Cleaners of the Series Etronic I and
Etronic II are not to be used in rooms with flammable or explosiveness
atmosphere. During operation of oil fired High Pressure Cleaners in enclosure
rooms, make sure that the exhaust is leaded off properly and there is sufficient
fresh air circulation.
Using High Pressure Cleaners in gas-stations or other hazardous areas
● refer to the regulation of „Technical rules for flammable liquids“
● the relevant safety regulations must be observed.
For special applications in rooms with flammable or explosiveness atmosphere
use only electrical heated High Pressure Cleaners of the appropriate EEx protection class.
The heating installation of the EHRLE Mobile High Pressure Cleaners of the
Series Etronic I and Etronic II underlie the regulations of fire equipments. The
heating installations must be inspected regularly in accordance with the respective national regulations of the legislator.
When setting them up, the locally applicable regulations must be observed.

Installation and Operating Instruction
Mobile Hotwater High Pressure Cleaners
Etronic I/II - HDE-Series
If a Mobile Hotwater High Pressure Cleaner of the Series Etronic I is not operated in the direct field of vision of the operating personnel, a flame monitoring
system must be retrofitted in accordance with DIN 4787. In the series Etronic II,
flame monitoring is fitted as standard.
Aerosols can be formed when using high pressure cleaners. An aerosol is a
mixture of solid or liquid suspended particles in a gas. Inhaling aerosols can be
harmful for your health.
Employers are obliged to perform a hazard assessment in order to define,
depending on the surface to be cleaned and the environment, protective
measures necessary to prevent inhalation of aerosols.
Respiratory protection masks of class FFP 2 or above are suitable for protection
against aqueous aerosols.
Using the device for longer periods can cause poor circulation in the hands due
to vibrations. A general period of use cannot be set, because this depends on
several influencing factors:
● Personal tendency to suffer from poor circulation (frequently cold fingers,
tingling sensation in the fingers)
● Low ambient temperature. Wear warm gloves to protect your hands.
● Holding the device too tightly hindering blood circulation.
● Continuous operation is more harmful than operation interrupted by work
breaks.
● pull over sharp edges
● repair.
Replace the defective HP-hose with an HP-hose approved by the manufacturer.

2 Safety
You should see a doctor if using the device regularly and for lengthy periods of
time, and in the event of repeated occurrences of symptoms such as tingling in
the fingers or cold fingers.
Exhaust gases are toxic. Never breathe in the exhaust gases. Ensure rooms
where the device is operated are sufficiently ventilated and that exhaust gases
can be conducted away.
Risk of burns. Never bend down over the exhaust gas opening and never reach
inside it. Do not touch the heating boiler while the burner is in operation. Never
close off exhaust gas openings
When operating the oil heated Mobile Hotwater High Pressure Cleaners of the
Series Etronic I and Etronic II, the exhaust air and the device parts around the
exhaust opening can become very hot. Do not touch or reach into these device
parts around the exhaust opening. Touching the parts can cause burns to persons. Before touching, wait until the parts have cooled down after operation
During combustion, exhaust gases are produced. Do not come into contact
with the exhaust gases during operation. The escaping exhaust gases are hot
and toxic. Contact with the exhaust gases or inhalation can cause burns or
poisoning to people.
The exhaust gas openings must never be closed or covered. There is a risk of
fire, among other things, if the exhaust gas openings are covered or closed.
During operation of oil heated Mobile Hotwater High Pressure Cleaners of the
Series Etronic I and Etronic II in enclosure rooms, make sure that the exhaust
is leaded off properly and there is sufficient fresh air circulation.
Observe the local regulations on the installation and operation of the high
pressure cleaners.

Lifting and moving loads is permitted for one person up to 23 kg. If the load
exceeds 23 kg use suitable lifting equipment (e.g. forklift, lift trucks).
Observe the international standard „ISO 11228-1 Ergonomie - Manuelles Handhaben von Lasten - Teil 1 Heben und Tragen 05/2003“.
2.6
Periodic inspections
The periodic inspections are listed in Section 8 (Maintenance).
2.7
Guidelines for pressure vessels and steam
boiler regulation
2 Safety
EHRLE High Pressure Cleaners comply with the German and European pressure vessel regulation and the steam boiler regulation. The water capacity is
less than 10 l. The high pressure cleaner is thus free of installation regulations
with respect to its boiler. For operation at temperatures higher than 100 &deg;C, for
unsupervised operation or the length of the high pressure hose exceeds 18 m,
the oil burner must be equipped with a flame monitor (the HD623 and HD640
are not equipped with a flame monitor).
Observe the local planning authority regulations.
2.8
Operator obligations
The operator must ensure that before each commissioning of the liquid sprayer,
its safety-relevant parts are checked for their perfect condition (safety relief
valves, HP-Hoses, trigger gun, electrical cable, fuel tank etc.).
2.9
Manufacturer tests and certificates
Before delivery the high pressure cleaner passed the following factory tests:
● heat coil water pressure test with 350 bar
● high pressure cleaner factory test
(the scope of delivery encloses the factory test protocol).

Installation and Operating Instruction
Mobile Hotwater High Pressure Cleaners
Etronic I/II - HDE-Series
2.10
Federal Immission Control Act
The heating installation (Series Etronic I and Etronic II, not HDE-Series) of the
EHRLE High Pressure Cleaner underlie the regulations of fire equipments.
According to these regulations oil- or gasfired high pressure cleaners have to
be checked annually by your responsible district chimney sweep to ensure observance of the emission limit values. The first test must be carried out within
the first four weeks after commissioning. The operator of the high pressure
cleaner must arrange for the measurement to be performed.
2.11
Guidelines for liquid sprayers
The device complies with the „Guidelines for liquid sprayers“. These guidelines
were published by the Federation of Institutions for Statutory Accident Insurance and Prevention and can be obtained from Carl Heymann-Verlag KG, Luxemburger Str. 449, 50939 Cologne, Germany.
High pressure cleaners must be inspected by an expert in accordance with the
„Guidelines for liquid sprayers“, if necessary or at least every 12 months. The
result of the test must be recorded in writing.
In the appendix of this manual there is a test sheet (proof of customer service)
to record the tests carried out.
EHRLE service technicians are experts and can be consulted and commissioned
by EHRLE service for this prescribed inspection.
2.12
Design changes to the device
2.13
Safety devices
Safety devices serve to protect the user and must not be suspended or circumvented in their function.
The high pressure cleaner has the following safety devices listed below:
● Pressure switches:
Device functions are switched on or off (safety functions) based on type of
construction and intended use.
● Unloader valve and non-return valve:
The first serves to adjust the operating pressure and the second valve keeps
the pump head depressurised when the trigger gun is deactivated.
● TSS system with pump-off delay:
After deactivating the trigger gun, the pump continues operation for approx.
30 s in the pressureless bypass mode (avoidance of too high pressure buildup in the pump); then the motor is switched off.
300907 • 1/2022 • H.S.

2 Safety
Design changes to the high pressure cleaner are not permitted.
Inadmissibly constructively modified devices can endanger the life and limb of
persons.
When operating a device which has been modified or changed in design, the
device will not be used for its intended purpose. If the device is not used for
its intended purpose, no liability or warranty will be accepted (see Section 1.7,
Warranty and Liability).
Installation and Operating Instruction
Mobile Hotwater High Pressure Cleaners
Etronic I/II - HDE-Series
● Total Switch-off:
Automatically switches the high pressure cleaner off in the event of
prolonged interruption of operation or unused trigger gun for more than
20 minutes.
● Overload protection switch:
When the motor current load is too high the switch releases and the device
is switched off.
● Mechanical arrest for trigger gun:
Prevents unintentional or unconscious activating the trigger gun.
2 Safety
● Thermo switch with switch-off in case of overtemperature
(only HDE-Series).

According to EN 61 770, the high pressure cleaner must not be directly connected to the public drinking water supply. However, according to DVGW (Deutscher Verband des Gas- und Wasserfaches - German Gas and Water Association), short-term connection is permissible if a backflow preventer with a pipe
ventilator is installed in the supply line.
Water after the backflow preventer is no longer considered drinking water.
An indirect connection to the public drinking water supply is also permissible by
means of a free outlet. The water supply must comply with EN 61 770, e.g. by
using a tank with a float valve. Direct connection to a pipe network not intended for drinking water supply is permissible.
The water supply capacity for the device must ensure a minimum of 1200 l/h
by a hydraulic pressure between 1 bar and 6 bar.
Equip the water connection of the tap water network with a shut-off valve.
Connect the high pressure cleaner to the water connection via a flexible water
supply hose (at least 1/2“).
