front of and behind the product. While assembling to adjacent elements, pay attention that no oppression force shall be applied on the
housing and the mounting components (bolts, o-rings, sliders) must be suitable for the geometry and working conditions of the
equipment. No changes should be made on the product (drilling, grinding, soldering etc.). To avoid exceeding usage limits (PS, TS), make
sure that the inlet side is protected with a suitable device. Sufficient buffer volumes should be left at the line outlet after the device,
before installation. Confirm the accuracy of the bumper volume on the outlet side. The buffer volume should be 1/500 of the flowrate
at pressures up to 300 mbar and 1/1000 at higher pressures.
Check the accuracy of the flow direction. See the arrow mark on the body. Vent and relief lines, which may be required, must be made
in accordance with applicable rules and laws. In mountings made with non-condensing gases, the product can be assembled in any
position. In mountings with condensed gases such as LPG, the product should be placed at horizontal or vertical flow direction and the
outlet side should be downwards. Installation should be carried out with appropriate and approved seals. The sealed surface should be
clean and soft and new seals should be used at all times. Clean the inner side of the entire pipeline where the product will be installed
with compressed air before mounting the product and take precautions to ensure that these lines will not be contaminated again. Make
sure there are no particles left at any point on the line (dust, dirt, sawdust, foreign particles etc.). The fluid that will flow to the product
must be filtered before the product. A filter with ≤ 50 μm pore width should be placed at the inlet side. The regulator and SSD should be
kept away from direct sunlight and corrosive atmospheric effects.
The said pressure equipment must be installed in a non-seismic area and should not be exposed to fire and lightning strikes. For outdoor
installations, the regulator must be located away from vehicle traffic and positioned so that water, ice and other foreign substances do
not enter the spring case through the ventilation hole. Avoid placing the regulator under fringes or down pipes. Make sure that it is above
the potential snow level. Check the risk of explosive mixture in the pipeline. Make sure that all valves used before and after the product
which provide gas flow to the product are closed. Before starting the mounting, ensure that there is no pressure gas trapped in the line
where the product will be installed and between the line and the product, that the gas supply is turned off and that the possibility of
opening is completely prevented. Prevent explosive gas-air mixture. Avoid contact voltage and ignition of sparks in the product.
Necessary measures shall be taken to ensure that there is no sound and vibration caused by the line. Before installation, take appropriate
measures (clamping at the line side etc.) at the line inlet and outlet to reduce bending and torsion loads caused by pipes and shocks.
Attention should be paid to the relevant limitations in counter forces and moments caused by pipes and connections.
Make sure that the necessary dimensions and areas are provided considering further operations (testing, maintenance, disassembly etc.).
In any case, check that the inlet pressure of the product shall be higher than the outlet pressure. Ensure that there are no diameter
narrowing and expansion over short distances at the inlet and outlet of the line on which the product will be mounted. Before installation,
it should be checked and ensured that the line pressure is within the inlet pressure range specified on the label on the product and that
the product capacity will not be exceeded during operation. It should be checked and ensured that there is no damage on the product
(visual and functional), that the product to be installed is suitable for the system to be used, that the pressure does not exceed the
maximum pressure level specified on the product label, that the product's dimensions fit with the line, that the installation place is at
adequate distance and under protection so that it will not be affected by sparks and electrical currents that may be caused by flammable
substances and devices.
Proceed with the installation process by taking necessary measures (such as protection box etc.) so that the product will not be exposed
to direct external environmental, corrosion and wearing conditions (sun, atmosphere, rain, snow, humidity, water, external chemicals
etc.) and to potential external damages and impacts. If the products are to be used in floor-mount applications, this should be indicated
while placing the order. In this case, products with properly coated surfaces should be used and appropriate measures should be taken
to prevent dirt, dust, dirt, liquid, etc. at the discharge part, if any, of the product. In addition, it should be ensured that the products shall
not be in form of embedded in full or in part into water, soil or liquids. If requested during order placing, the regulator may be equipped
with a breath line for leaking into the atmosphere as a result of a failure (such as diaphragm failure). If necessary (e.g., the use of the
product indoors etc.), the exhaust line must be connected to the breath line console of the product. This connection must be threaded
with minimum DN10 screws. The threaded screw adapter required for this connection shall be requested and used from the
manufacturer and shall be used accordingly. Gas pressure regulators and SSDs with discharge system; shall not be installed and operated
in closed areas and floor-mount applications without taking necessary measures for transmitting the gas to be discharged to the safe
zone (e.g. transmitting and mixing the gas to be discharged with a pipe of minimum DN 10 to external atmospheric conditions, etc.).
Before installing the product on the line; perform a general check for the pressure and sealing of the line and system.
B. DURING MOUNTING
Manually remove the inlet-outlet connection protection plugs, if any. If the product is equipped with modular connection additionally,
manually and carefully place the inlet and outlet seals which are shipped in the product box to the inlet and outlet connection nozzles
(always use certified and new seals). Set the flow direction of the product by showing the arrow outlet side and gas flow direction in the
product body and ensure that the joint components to be used during installation shall comply with the regulations. Install the product
only in accordance with applicable legislations and local regulations, obtaining the necessary approvals, if necessary. Do not install the
product outdoors without mounting the product into a housing and taking required protective measures. The lifting equipment being
used must be suitable for loads to be lifted. While connecting the product to the line no overload, force and impact shall be applied.
