Malfunctions caused by residues!
Proper functioning is not guaranteed.
Visually check that there are no metal chips or other residues in the connections!
It is important that metal chips or other residues are blown out!
Install with suitable tools, if required.
Regarding screw connections, use a second spanner to brace against the connection nozzle.
Do not use unsuitable tools, such as pliers.
Product damaged through incorrect installation direction
Proper functioning is not guaranteed.

Screw connections
If connections leak, there is a danger of explosion, fire or suffocation!
Gas may escape if the product is turned.
Do not turn the product after it has been installed and the connections have been
tightened.
Tighten connections only when they are not pressurised.
If re-assembling, change the gaskets.
Make sure that the gaskets sit properly in the mounting and that the screws are tightened.
Connecting and installing hoses assemblies
•
Connect hoses so that mechanical, thermal and chemical stresses are avoided:
mechanical stress: e.g. do not pull the hose assembly over sharp edges
thermal effect: e.g. avoid open flames, radiant heat
chemical effect: e.g. avoid grease, oil, caustic substances
•
Install hose assemblies so that they are not under tension (no bending and tensile strains
or torsion).
•
Install hose assemblies so that their connections cannot loosen unintentionally.
•
Connections to the pressure regulator with 90° outlet prevent the hose assembly from
being kinked.
•
Observe the applicable national installation regulations for LPG systems.
Suitable high-pressure hoses must be used for connection to the gas cylinders.
Example of application:
Four-cylinder system to operate with large cylinders with remote display option
Low pressure regulator with
safety overpressure shut-off
valve (OPSO) and pressure
relief valve PRV, GS excess
flow valve, automatic
changeover valve type AUV
with electronic remote display
and hoses and pipes upstream
from the changeover valve.
