2.4 Unauthorized alterations and spare parts
Modification or alteration of the tank regulator combination
type 110/111 is not permitted. Original drawings and
accessories authorised by the manufacturer serve for safety.
The use of other parts or unauthorised modifications to the
type 110/111 tank regulator combination by third parties
invalidates the manufacturer's liability for the consequences.
2.5 Permissible operating mode
•
liquid gas (gas phase), others on request
•
ex zone 1 or 2
•
under the container cover (above ground,
underground), in weather-protected outdoor areas,
•
in buildings and special installation rooms (according
to TRF 2012)
2.6 Inadmissible operating mode
•
ex-zone 0
•
operating modes that deviate from the permissible
operating modes and technical data
3. Handling
3.1 Transport
During all transportation, the generally recognised rules of
technology and the accident prevention regulations must be
strictly observed.
Handle the goods to be transported with care. During
transport, the pressure regulator must be protected against
shocks, blows or vibration.
Immediately after receipt of the goods, the delivery must be
checked for completeness and transport damage.
See also section 9.0.
3.2 Storage
If the pressure regulator is not installed immediately upon
delivery, it must be stored properly.
Storage temperature -20°C to +60°C, dry, free of dirt and
protected from moisture.
3.3 Handling prior assembly
•
Protect from weather influences such as wetness
•
Make sure that the product is free from dust and
foreign particles
4. Product specification
4.1 Safety shut-off valve (OPSO)
The overpressure safety shut-off device OPSO is open during
normal operation and is designed to shut off the gas flow
automatically as soon as the set response pressure is
reached in order to protect downstream equipment from
impermissibly high pressure. It must be opened manually
after closing (see OPSO restart).
4.2 Pressure regulator 1
st
stage
The 1
st
stage pressure regulator reduces the unregulated
pressure from the liquid gas container to a set outlet pressure.
4.3 Pressure Relief Valve (PRV)
The PRV (Pressure Relief Valve) is closed during normal
operation and is designed to automatically release the gas
flow with limited flow when the pressure in the system to be
protected reaches the set pressure. This is relieved via the
regulator's venting port. It closes again automatically when
the pressure drops below the set pressure.
The outlet opening must be protected against rainwater.
It is important to note that pressure regulators which
are operated inside a building, an enclosure or a
hazardous area must be provided with a vent line to
the outside.
Please observe this information, otherwise liquid gas
can escape in the building, which may lead to an
explosion.
Insect screen with filter screen must be screwed into
the vent on the regulator. It must be checked
regularly whether the screen is free from dirt. A
clogged screen can lead to increased or too low
outlet pressures and thus to a response of the
OPSO.
4.4 Pressure regulator 2
nd
stage
The pressure regulator of the 2nd stage reduces the output
pressure of the pressure regulator of the 1st stage to a fixed
output pressure of 50 mbar.
4.5 Emergency supply (Type 111)
If the gas tank should unexpectedly run out of gas, the gas
supply can be secured by means of a gas cylinder via the
emergency supply connection using a high-pressure hose.
This is not a permanent solution. It only serves as a
temporary solution until the gas tank is filled again.

6. Assembly
6.1 Information on hazards during installation, operation
and maintenance
DANGER!
Safe operation of the pressure regulator is only
guaranteed if it is installed and commissioned by
qualified personnel (see point 2.3 "Qualified
personnel") in accordance with the warnings in this
operating manual. Proper use of tools and protective
equipment must be ensured. The operating
instructions of the pressure regulator must be
observed during all work on the pressure regulator or
when handling the pressure regulator.
