C. AFTER
If the setup process does not occur or f you encounter different problems afterwards; contact the manufacturer without carrying out
any operation.
The setup shall not affect the function of other components.
Under closed conditions or inside, the leaked gas can accumulate and create danger of explosion. In such cases, the ventilation hole
should be connected by piping from the product to outdoors (atmosphere).
If the product is exposed to excessive pressure, it should be checked for any damage that may have occurred. If the overpressure is high
enough to damage the product, some kind of external overpressure protection must be provided.
The product
’s operation under the limits specified in
this manual and the product label: This does not prevent damage caused by external
sources or residues in the pipeline. The inlet must be protected with appropriate equipment to avoid exceeding the permitted limits (PS,
TS).
When designing a decompressing station, carry out an analysis that takes into account the impact of wind, snow and temperature to
prevent unnecessary load and equipment from moving towards the flanges and take the necessary measures according to this analysis.
If necessary, a support can be used under the pipe and regulator/SSD body to prevent excessive pressure on the regulator/SSD.
The installed product shall be adequately protected from vehicle traffic and damage from other external sources.
Do not install the product where excessive water accumulation or ice formation can occur. In some installations, such as in areas with
heavy snowfall, a cap or enclosure may be required to protect the product from the snow load and to prevent freezing caused by air
discharge. The necessary measures should be taken considering the aforementioned situations.
Depending on the temperature during and after the installation process or during mid seasons, instant gas output from the
product’s
relief section may occur which is normal. It is important that such gas output in question shall not continue; if it continues it can be
considered that there is a failure in the product. In such a case, the products use shall be discontinued and the authorized
persons/organizations should be contacted immediately.
If the product is closed for various reasons during operation, the inlet and outlet valve should be closed, the problem should be detected
and the product shall be re-installed according to the aforementioned rules.
If the product is equipped with a discharge system; gas discharge to the atmosphere shall not be performed under any circumstances;
however, there may be temporary discharges from auxiliary equipment. If there is a continuous discharge contact the authorized
person/institutions immediately.
If the product is shut down for various reasons during operation:
1- The inlet and outlet valve should be closed, the problem should be detected and re-installed according to the aforementioned rules.
2-
The output pressure may increase and the product’s high pressure safety shut
-off device may close which will lead to gas cut-off,
depending on contaminated gas and foreign matters in the line, which will cause pressure-capacity changes due internal leakage,
abrupt stop of the combi boiler, boiler etc., breathing line clogging, product failures etc. In this case, the reinstallation process has to be
repeated.
3- If the output pressure of the product drops excessively for various reasons during operation and reaches the adjusted safety
pressure, the low-pressure safety shut-off system activates and the gas flow may close. In this case, the reinstallation process has to be
repeated.
- TESTS
After installation, output pressure, high- and/or low-pressure closing pressures and internal impermeability, external impermeability and
the capacity should be checked. While performing these procedures, take all necessary measures to ensure that the discharged gas
generated from the product or the external leakage shall not a hazardous atmosphere and do not operate indoors.
Note: In no case should operations be performed which lead to pressure income or pressure flow of more then 20 bars to the inlet
connection nozzle and body of the product or to pressure income or pressure flow of more then 6 bars to the housings where the
product’s outlet pressure adjustments are made and such situations shall be strictly prevented
.
To examine the pressure values; carry out this procedure with a calibrated manometer mounted on minimum 5xDN in the pipeline at
the outlet side of the product. DN is the value that depends on the diameter at the output of the product.
