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.
Observe the installation direction (marked on the product with an arrow
).
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.
Installing a gas filter
We recommend installation of a gas filter (Part no. 02 013 10) in front of the pressure
regulator.
LPG may contain foreign matter, such as dirt particles. From a certain size, these particles are
trapped in the filter. If no gas filter is installed, wear and tear of sensitive components is
increased and the complete LPG system may break down.
Install the pressure regulator so that it is not under tension.
Use the regulator support.
For outdoor applications, the product must be located or protected so that no
dripping water can enter. We recommend installation in under a hood and in a control cabinet,
respectively, or in a housing.
If the pressure regulator is installed in the flow direction downstream from another pressure
regulator, the supply pressure range must correspond to the regulated pressure range of the
first pressure regulator, with consideration of the pressure loss in the piping between the two
devices.
LEAK CHECK
Risk of burning or fire
Serious burns to the skin or damage to property.
Do not use an open flame to check for leaks.
