Leak Check - GOK NDR 0515 Montage- Und Bediensungsanleitung

Assembly notes
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.
Install the pressure regulator so that it is not under tension.
Use the regulator support.
Product damaged through incorrect installation direction
Proper functioning is not guaranteed.
• Observe the installation direction (marked on the product with an arrow
To install the connections, see CONNECTIONS in the assembly manual.
If compression/separation connectors are used in the building, a 1st stage regulator with
maximum 1 bar shut-off pressure of the safety overpressure shut-off valve (OPSO) must be
used.
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.
For outdoor applications, the product must be located or protected so that no dripping
water can enter. We recommend installation in under a hood or in a gas pressure regulator
box, 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

Serious burns to the skin or damage to property.
Do not use an open flame to check for leaks.
Leak check before start-up
Before start-up, check the product connections for leaks!
1. Close all shut-off fittings on the connected devices.
2. Slowly open the withdrawal valve or the gas cylinder valve(s).
3. If there is a safety device (e.g. EFV) between the tank and the connected device(s),
open this during the leak check.
4. Spray all connections with a foam producing substance according to EN 14291
(e.g. leak detector spray, Part no. 02 601 00).
5. Bubbles will form in the foam producing substance if there are any leaks.
If you cannot stop the leaks, you must not use the product.

Risk of burning or fire
If more bubbles form, re-tighten the connections (see ASSEMBLY).
