3- TERMS OF USE, TECHNICAL INFORMATION AND OPERATION PRINCIPLES
Functionally, the regulator reduces the value of the controlled variable (outlet pressure) to the desired/adjusted value
and keeps it within the tolerance range without being affected by the detrimental variables such as flow rate and inlet
pressure. The gas pressure regulator helps the devices that come after itself on the gas line function safely. If requested
on the order, the gas pressure regulator may have a release system that releases to open air. The auxiliary equipment
of the regulator may temporarily release gas to the atmosphere. In this case, necessary precautions regarding the gas
that will be released must be taken before the assembly. The transmission lines are internal in the regulators.
The gas pressure regulator also has a capacity restriction system, which is activated when the outlet flow rate is at
101% to 150%.
The gas pressure regulator is not pilot-operated. It does not have controlling properties. It does not need a bypass unit
in order to function. It is not used as a substitute controlling device. It has a two-stage trigger spring.
On the ERG-SE series gas pressure regulators, there's a high pressure safety shut-off device on the same body (meaning
it's integrated on the regulator), which gets activated when the outlet pressure increases to unwanted levels,
automatically shuts off the gas on the line and remains shut off until being manually set up. This device is functionally
independent from the regulator.
Note: Since there isn't a safety shut-off device that shuts off the pipeline in case of excessively high outlet pressure on
the ERG-S series products, additional precautions must be taken by relevant parties regarding the unwanted excessive
pressure increase on the outlet side of the line.
The technical properties of the product are as follows. These values may vary from product to product depending on
factors such as outlet flow rate, outlet pressure, inlet pressure range, etc. The definitive technical information of the
product is specified on the label. Under any conditions, the product must not be used outside of the restrictions below.

4- ASSEMBLY
These procedures must be carried out by expert, licensed, authorized technicians or authorized companies, services
or installers that have been certified by the gas board. These procedures absolutely must not be carried out by the end
user. In case the product is not installed appropriately, any malfunction or breakdown may lead to injuries or loss of
life and property. Our company cannot be held responsible for any application that does not comply with the manual.

Before the assembly, determine and make sure with which properties you are going to use the product. Check the
technical and general information specified on this manual and the label on the product. Compare them and make
sure you make the right choice. Pay special attention to the information on the label since it represents the product.
If there are any discrepancies between these information, contact the manufacturer before carrying out any
procedure. Check the accessories and the documents that might be on the product or the box (As shown in Figure 8;
the inlet filter that can be found on the inlet connection side, the outlet gasket (For ERG-SE series No:12, for ERG-S
series No:9), shut-off protection cap number 9 (Only for the ERG-SE series), lever plastic number 7, protection caps on
the connections if they exist, pressure adjustment seals if they exist, release protection cap number 3 if it exists,
manual, alert information if it exists, etc.). Compare the product and the line on which the product will be installed
and make sure they are suitable for each other (working pressure range, outlet pressure, fluid, flow rate,
environmental conditions, cleanliness of the line and the fluid, choosing the connection types and diameters,
compliance of the line and the product dimensions, etc.). If there's something missing or faulty, contact the
manufacturer before carrying out any procedure. You must check and make sure that the product doesn't have any
damages (visual or functional), the product to be installed is suitable for the system, the pressure doesn't exceed the
maximum pressure level specified on the label, the dimensions of the product comply with the line, and the assembly
area is at a safe distance from the sparks or electrical currents that might originate from flammable materials or
devices.
Note: While choosing the flow rate of the regulators, you must determine the maximum capacity of the line where the
product will be installed. Choose a regulator that has a maximum capacity smaller than this value.
The regulator must not be exposed to fire or lightning. For outdoor installments; the regulator must be away from the
traffic or external factors. It must be placed in a way that will prevent water, ice or other foreign substances from
entering the spring box through the ventilation opening. Avoid placing the regulator under a fringe or the downpipes.
Check for a risk of explosive mixtures inside the pipeline. Make sure that the product is above the potential snow level.
The product must be mounted in an aseismic area or in an area where the necessary precautions have been taken for
seismic activity.
Check and make sure that the inlet and outlet pipelines are aligned. Verify that the assembly is being done in
accordance with current technical laws and legislations. While assembling with adjoining components, special
attention must be paid not to apply pressure force on the body, and the assembly components (bolts, o-rings, screws)
must comply with the geometry of the device and the working conditions. You must not make any changes on the
product (drilling, stoning, soldering, etc.). In order to avoid exceeding the usage limits (PS, TS), make sure that the inlet
side is protected with an appropriate device.
Make sure that the connecting components that will be used during the assembly comply with the regulations.
Assemble the product in accordance with the current legislations and local regulations. Obtain the necessary permits
if necessary. Prevent the mixture of explosive gases and air, and control by taking measurements. Avoid any contact
voltage and flammable spark on the product.
There must be an inlet and outlet shut-off valve before and after the regulator on the line where the mounting will be
carried out. Before and during the assembly, make sure that there isn't any compressed gas between the product and
the line or on the line itself. Make sure that the gas supply is shut off and there aren't any possibilities for it to be
turned back on. Before the assembly, it must be checked that the line pressure is within the inlet pressure range
specified on the product label and that the regulator capacity will not be exceeded during operations. Before the
assembly, an adequate buffer volume must be left on the line outlet after the regulator. The recommended buffer
volume is 1/500 of the nominal flow on the products with outlet pressure up to 300 mbar, and 1/1000 of the nominal
flow on the products with outlet pressure over 300 mbar. Necessary precautions must be taken in order to avoid any
noise or vibration originating from the line. There must not be axial misalignment on the line that will be mounted. For
humid gases, necessary precautions must be taken in order to avoid water intake and potential subsequent freezing.
Before the assembly, take the necessary precautions through methods such as clamping on the line part, etc. in order
to reduce the bending and torsional load resulting from the pipes and the jolting on the inlet and outlet sides of the
line. Make sure that the load of the pipeline does not affect the product. Make sure that there aren't any short-range
shrinkage or enlargement of the diameter on the inlet or outlet sides of the product. Ensure that the necessary

dimensions and space are provided by taking the product's external dimensions as reference and taking the future
procedures such as testing, maintenance, removal, etc. into consideration. Verify that the inlet pressure of the product
is higher than the outlet pressure and that it will be higher under all circumstances. Before assembling the product on
the line, clean the internal parts of the pipe with compressed air and eliminate the foreign substances such as dust,
dirt, sawdust, welding particles, etc. Take the necessary measures to prevent these lines from getting contaminated
again. Carry out the general pressure and tightness controls of the line and the system. Make sure that an external
filter is installed in order to filter out the gas before the gas pressure regulator. Assemble the products by taking the
necessary precautions (e.g. inside a protective box, etc.) so that they won't be exposed to external damage or impact
resulting from the environmental factors or external corrosion (sunlight, rain, snow, moisture, water, external
chemicals, etc.)
In order to start the assembly: Obtain the necessary permits from the gas distribution companies. Take all necessary
measures considering all risk variations and combinations. Make sure that all valves that supply gas to the product are
turned off and there's no gas flow. If they need to be used, make sure that the connection components comply with
the regulations. Do not use materials such as putty, special liquids, etc. in order to ensure tightness in the connections.
The gaskets that will be used during the assembly must be the appropriate and licensed gaskets, and they must be new
with the appropriate rigidity. Make sure that the gaskets do not have a flaw that will affect their tightness properties.
Remove the product from the box and manually remove the inlet-outlet connection protection caps if they exist. Make
sure that the inlet filter is correctly mounted on the inlet connection part. If it's not, mount it manually. Manually place
the outlet gasket that comes inside the box (No:12 for ERG-SE, No:9 for ERG-S) on the outlet connection nozzle (always
use new and licensed gaskets). Set the flow direction of the product in a way that the arrow on the product's body
indicates the outlet side and the gas flow direction. With a tolerance range of ±5oC, set the position of the product for
the dry gases horizontally or vertically like it has been specified on Figure 1, provided that the upper hatch part, which
includes the outlet pressure adjustment part, does not face the floor. If the fluid is LPG, set the position by making sure
that the regulator outlet side faces the floor. Place the product on the line without applying excessive load, force or
impact and in a way that will not block the product's outlet sense line or will not expose it to mechanical stress. Tighten
the product's inlet and outlet connections number 6 (No: 11 for ERG-SE, No:8 for ERG-S) by using the appropriate
wrench without using excessive load, force or impact; making sure that there aren't any external leaks. After the
tightening procedure; make sure that the connections settle in the bearings perfectly, that there aren't any mechanical
problems on the connections such as fractures, etc., and that there aren't any mechanical stress on the product
originating from the line, pipe or connections.
If the product has flanged connections; observe that the inlet and outlet flanges are the same as the line connecting
flanges in order to prevent unnecessary mechanical stress on the product body. Make sure that they are aligned
perfectly and are parallel to each other. Tighten the nuts and bolts gradually in a diagonal pattern in gradually
increasing torques. Tighten each nut clockwise at least once more until the maximum torque is obtained. Also,
calculate the necessary gap to place the tightness gasket and center the gaskets appropriately in the connection. If
there's a gap between the line and the product, do not try to reduce the gap by tightening the gaskets more than
necessary.
Provide protection for the product (e.g. by storing it in a box, etc.) so that unauthorized personnel do not tamper with
it, bump into it or accidentally touch it. After the assembly is completed, check and make sure that you have not
assembled the product the wrong way around, that you have complied with current laws and local regulations, and
that you have carried out the procedures in accordance with the information on this manual.
The relevant restrictions must be taken into consideration regarding the reaction and momentum resulting from the
pipe and the connections. In case the connection components that have been installed on the inlet and outlet sides of
the product are bigger than the connection diameters on the product's body (fittings, nozzles, etc. before installment),
you must not use any force or momentum that exceeds the values required by the main connection diameter on the
body and you must not go over the restrictions. In this context, the bending and torsion load limits of the product may
change according to the direction of the line connection. Regardless of the product's inlet and outlet pipe connection
diameters or nozzle diameters; the maximum loads that can be applied on the product are 10.5kg bending and 5kg
torsion on the inlet sides, 34kg bending and 12.5kg torsion on the outlet side that has a bigger diameter, and 22.5kg
bending and 8.5kg torsion on the outlet side that has a smaller diameter. It's recommended that the impact of these
loads do not go over 10 seconds. Otherwise, the product may malfunction.

If the products are going to be used in floor type applications, this must be specified during the order stage. In this
case, the products that have been appropriately coated on the outer surface must be used. Necessary precautions
must be taken in order to prevent dirt, dust, liquid, etc. from entering the release part of the product if it exists. Also,
it must be made sure that the products are not used while completely or partially immersed in water, earth or other
liquids. If necessary, the exhaust line must be connected to the ventilation console of the regulator. This connection
must be at least DN10 threaded. The threaded adaptor that might be necessary for this connection must be requested
and used. The gas pressure regulators with a release system must not be mounted indoors or on floor type applications
without taking the necessary precautions for the gas to be released into a safe area (for instance, the released gas
must be released and mixed into the atmosphere through at least a DN10 pipe, etc.).

5- SETUP, START-UP AND OPERATING
Before the setup, carefully read the instructions on this manual and the information on the product label. Keep them
close and strictly follow them. If you think there's missing or faulty information, do not carry out any procedures and
contact the manufacturer.
Before the setup, check and make sure that the people at the outlet side are not using the device. Do not change the
factory settings. The factory settings have been adjusted according to the values requested on the order contract and
they have been specified on the label. The adjustment equipment are sealed if requested on the order contract. Give
the necessary warnings so that the end users do not use it. Before starting the setup, you must first shut down the
main gas supply. Before setting up the device, make sure that the product has been assembled correctly on the line.
During the setup, prevent particles such as dirt, rust, dust, etc. from entering the device and take lasting precautions.
Not getting rid of the residue leads to damages or faulty performance.
During the start-up, unauthorized personnel must absolutely be kept away from the device and the limited access area
must be appropriately marked (signs, barriers, etc.). During the start-up; in case flammable or hazardous fumes are
released into the atmosphere, the risks that have been determined in case of a discharge must be assessed. During
the setup, take into consideration the risk of generating an explosive mixture (gas/air) in the pipes. Take the necessary
measures. Make sure the ventilation and/or the exhaust lines on the product are not obstructed. Take the necessary
precautions to make sure that these lines are not obstructed in the future. Do not install caps on these lines such as
blind caps that may block the gas outflow.
For the ERG-SE series products;
In order to begin the setup: Partially turn on the outlet valve on the line. Slowly and gradually turn on the inlet valve
on the line, which is the gas supply. Manually turn the transparent shut-off protection cap number 9 counterclockwise
to remove it (procedure no:1 on Figure 2). Manually and slowly pull the shut-off lever number 8 towards yourself

without applying any excessive load, force or impact. Wait for a couple of seconds to make sure that the lever remains
pulled, and then set up the shut-off part. If this procedure is not completed successfully, repeat it. Then, reattach the
shut-off protection cap number 9. Manually turn the lever number 7 counterclockwise slowly and gradually without
overextending or using excessive load, force or impact (procedure number 2 on Figure 2). Set up the device by verifying
that there's a gas flow on the outlet side, the lever number 7 has gone back to its initial position, and the shut-off lever
number 8 has remained pulled and locked. If this process does not occur, repeat the procedure. (During these
procedures, if you have difficulties turning the lever number 7, have difficulties pulling the shut-off lever number 8, or
if the shut-off lever number 8 turns off because the outlet pressure reaches the safety adjustment pressure; you may
carry out procedures such as removing the release protection cap number 3 if it exists (procedure number 3 on Figure
3), gradually turning on the inlet valve instead of completely turning it on, letting a small amount of gas to be released
from the test nipple on the outlet line, pulling and holding the shut-off lever number 8 for 3 to 5 seconds while locking
the lever number 7 and letting go of the shut-off lever number 8 when you detect a gas flow on the outlet side and
verifying that the lever remains pulled, etc. After these procedures, reattach the parts that you have removed such as
the release protection cap number 3, test nipple, etc.)
For the ERG-S series products;
In order to begin the setup: Partially turn on the outlet valve on the line. Slowly and gradually turn on the inlet valve
on the line, which is the gas supply. Manually turn the lever number 7 counterclockwise slowly and gradually without
overextending or using excessive load, force or impact (procedure number 2 on Figure 2). Set up the device by verifying
that there's a gas flow to the outlet side. If this process does not occur, repeat the procedure. (If you have difficulties
turning the lever number 7 during these procedures; you may carry out procedures such as removing the release
protection cap number 3 if it exists (procedure number 3 on Figure 3), gradually turning on the inlet valve instead of
completely turning it on, letting a small amount of gas to be released from the test nipple on the outlet line, etc. After
these procedures, reattach the parts that you have removed such as the release protection cap number 3, test nipple,
etc.)
After setting up the device; manually reattach the shut-off protection cap number 9 for the ERG-SE series products
and the release protection cap number 3 for all products if it exists. Make sure that there's a gas passage to the outlet
side, that the lever number 7 has remained in the same position prior to the setup, that the shut-off lever number 9 is
in the drawn position for the ERG-SE series products, and that the released gas can be mixed into the atmosphere if a
release system exists on the product. Inform the gas users regarding gas usage.
Besides, after setting up the device, make sure that the inlet and outlet valves are on and that there's pressure on the
outlet side. Check all external parts of the product including the connections by using methods such as appropriate
foam, liquid, detector, etc. and verify that there isn't any external leak on the product or excessive noise or vibration
on the line or the product. Connect the appropriate manometer, which has been connected to the pressure source, to
the test valve that is located on an appropriate spot at the outlet line after the regulator (during this procedure, make
sure that the connections are tight and leakproof). When there's a consumption of 0,5xQmax on the outlet side of the
regulator, measure the outlet pressure and check whether or not it's within the tolerance range. Shut off the outlet
valve on the outlet side of the regulator and wait for a while. Check whether the outlet pressure is stable and there
aren't any internal leaks. In order to make sure that the external leak or the released gas originating from the product
do not create a dangerous atmosphere while carrying out this procedure, take all necessary measures and do not
operate it indoors. The procedures that may lead to pressure inflow to the inlet connection nozzle and the body higher
than the determined PS value must not be carried out under any circumstances and this situation must not be allowed.
Analyze the pressure values with the calibrated manometer that has been assembled at least 5xDN on the outlet
pipeline. In order to avoid any kind of gas leak or fizzling out of the gas burning device, etc. by the user during all these
procedures, the users must be informed appropriately and the necessary measures must be taken.
During the setup procedure or during mid-season, as a result of temperature difference, etc., there may be a gas
outflow into the atmosphere from the release part of the product. This is normal. It's important that the gas outflow
in question is not continuous. If the gas outflow is continuous, there might be a malfunction in the product. In this
case, do not keep using the product. Immediately contact the authorized people and competent bodies, and take the
necessary safety measures on the line.
At indoor areas, the leaked gas may accumulate and create a risk of explosion. In such cases, the connection must be
carried out through a pipe from the product's ventilation hole to the outdoors (atmosphere).

If the gas pressure regulator is shut down during operation for some reason; the inlet valve must be shut down, the
problem must be detected, and it must be re-setup according to the rules explained above.
On the ERG-SE series products, the outlet pressure may increase while operating due to the abrupt stopping of the
boiler or an internal leak originating from unclean air or the foreign substances on the line. When this happens, the
product's high pressure safety shut-off device may be turned off and the gas on the outlet side of the regulator may
be cut off. The position of the safety shut-off can be observed via the lever number 8 which is inside the transparent
cap number 9. In this case, the setup procedure must be carried out once again.
During operation, if there's an increase in capacity by 101% to 160% of the maximum capacity specified on the
regulator, the capacity restriction system is activated and the gas flow is cut off. In this case, the setup procedure must
be repeated. (In this case, the shut-off lever number 8 on the ERG-SE products remains in the locked position and is
not turned off, but the gas has been cut off by the regulator)
6- SETTINGS
If necessary for a variety of reasons, the product's outlet pressure and safety shut-off pressure settings (for ERG-SE
series products) must be carried out as follows. Under normal conditions, there's no need to change these settings.
These settings must be changed if the authorized people think it's necessary.
The settings must not be changed more than ± 10% and outside the restrictions on the label.
The seals on the adjustment parts of the product must be removed if they exist. While carrying out the pressure
settings, the adjustment mechanisms and the springs must not be pressed or forced. Connect the pressure gauge or
the manometer on an appropriate test valve between the regulator and the outlet pipe in order to see the setting
values. During all adjustments, turning it clockwise leads to pressure increase and turning it counterclockwise leads to
pressure decrease. When the outlet pressure is increased, the safety pressure must be increased as well.
In order to change the outlet adjustment pressure: manually turn the cap number 1 on Figure 8 counterclockwise to
remove it. Turn the adjustment ring number 2 towards the appropriate direction with a 27mm hexagonal wrench.
Mark the adjustment pressure. Manually turn the cap number 1 clockwise to reattach it.
Note: While setting the appropriate pressure for the product, it's recommended that you set the capacity value on the
outlet side to 0,5xQmax. This value must not be below 0,1xQmax under any circumstances.
In order to change the high pressure safety pressure on the ERG-SE series products: manually turn the cap number 9
on Figure 8 counterclockwise to remove it. Turn the adjustment ring number 10 on Figure 8 towards the appropriate
direction with a 13mm hexagonal wrench. Mark the adjustment pressure. Manually turn the cap number 9 clockwise
to reattach it.
In order to change the release system release adjustment pressure if it exists: manually turn the cap number 1 on
Figure 8 counterclockwise to remove it. Turn the adjustment ring in the internal part on Figure 4 towards the
appropriate direction with a 16mm hexagonal wrench. Mark the adjustment pressure. Manually turn the cap number
1 clockwise to reattach it.
After changing the settings; check and verify with appropriate methods that the technical properties and the
restrictions on this manual and on the product are complied, the product does not continuously release gas into the
atmosphere, the outlet pressure is at the desired level, and all procedures are carried out safely and correctly. After
making the pressure adjustments in question, it's recommended that the adjustment equipment is sealed on the
products that are being used in the field so that the adjustments cannot be changed. For this procedure, the seal inside
the box may be used if it exists.
Note: When the outlet adjustment pressure of the product is changed, taking into consideration the changes in the
working conditions, it must be verified that the pressure values are not close to the release adjustment pressures (if it
exists) and safety adjustment pressures, and that they are not within this range. Otherwise, the product continuously
releases gas into the atmosphere or the product's safety shut-off mechanism may get activated and unexpectedly cut
off the gas, which may lead to dangerous situations. It must be made sure that these situations do not occur after the
settings are changed.

7- PERIODICAL MAINTENANCE AND INSPECTION
Periodical inspection is recommended for making sure that the regulator functions safely and properly. The frequency
of periodical inspections must not exceed the limits specified by the gas board or the regulations. The maintenance
period must be adjusted according to the working conditions. End users must not carry out any maintenance procedure
for the product.
During all procedures, the instructions on this manual must be complied. All periodical maintenance procedures must
be carried out after removing the product off the line. Do not carry out abrupt discharge in order to clean the line after
the product under any circumstances. Do not start any maintenance procedure before releasing the internal pressure
that might have accumulated inside the product. For the necessary periodical maintenance, remove the product off
the line in accordance with the disassembly rules specified on this manual.
For the necessary periodical maintenance that does not have to be carried out on the line, remove the product off the
line according to the removal rules specified on this manual. Manually remove the filter that has been mounted on the
nozzle on the inlet connection side and the outlet gasket that has been mounted on the outlet connection nozzle.
Clean them appropriately. If necessary, replace them with new ones. Then, remount them. Remove the screws on the
regulator caps without any stress using appropriate tools and remove the caps manually. Do not remove the parts of
the caps that have been removed. Keep the caps as a whole with their parts inside. Clean these parts slowly with a
clean washcloth. On the ERG-SE series products, you must also remove and clean the filter inside the shut-off valve if
it exists. Make sure that the connection components of the product (screws and/or gaskets and nuts) are mounted
and removed using the specified torques. Mount the caps using the same screws, without applying stress on the screws
or using excessive force by tightening them so that they align with the holes. Make sure that they are not loose or that
they have not been exposed to any mechanical damage. When the maintenance is completed, assemble the product
on the line and set it up according to this manual.
Note: If there's any kind of paint, lacquer, seal, etc. on the connection parts of the regulator such as screws, etc., do
not carry out any maintenance procedures and contact the manufacturer. Do not carry out the cleaning procedure
with cleaning supplies that contain alcohol or solvents. After the periodical maintenance procedure, it's under the
responsibility of the institution that carries out or requests the periodical maintenance to make sure that the product
is operated safely and correctly at values that have been specified by the manufacturer. In this context; in cases where
you have any doubts, you must not install the products on the line and you must contact the manufacturer.
For the periodical maintenance that can be carried out on the line without removing the product, make sure that the
inlet and outlet valves are turned on and that there's pressure on the outlet side. Check all external parts of the product
including the connections by using methods such as appropriate foam, liquid, detector, etc. and verify that there isn't
any external leak on the product or excessive noise or vibration on the line or the product. Connect the appropriate
manometer, which has been connected to the pressure source, to the test valve that is located on an appropriate spot
at the outlet line after the regulator (during this procedure, make sure that the connections are tight and leakproof).

When there's a consumption of 0,5xQmax on the outlet side of the regulator, measure the outlet pressure and check
whether or not it's within the tolerance range. Shut off the outlet valve on the outlet side of the regulator and wait for
a while. Check whether the outlet pressure is stable and there aren't any internal leaks. In order to make sure that the
external leak or the released gas originating from the product do not create a dangerous atmosphere while carrying
out this procedure, take all necessary measures and do not operate it indoors. The procedures that may lead to
pressure inflow to the inlet connection nozzle and the body higher than the determined PS value must not be carried
out under any circumstances and this situation must not be allowed. Analyze the pressure values with the calibrated
manometer that has been assembled at least 5xDN on the outlet pipeline. In order to avoid any kind of gas leak or
fizzling out of the gas burning device, etc. by the user during all these procedures, the users must be informed
appropriately and the necessary measures must be taken.
After the tests in question, make sure that all accessories and apparatus such as the shut-off protection cap (on the
ERG-SE series products), the lever plastic, the pressure adjustment seals if they exist, the release protection cap if it
exists, the release sieve if it exists, etc. are mounted on the product. Set the device up by following the setup rules
specified on this manual.
If any problems are observed during periodical maintenance or inspection, the necessary procedures may be carried
out in accordance with the rules explained in the malfunction section.
8- CUT-OUT, REMOVAL AND CHANGING
Before, during and after all removals and changes, follow the rules specified on this manual and carry out the necessary
procedures. Before and during the removal and changing procedures; make sure that there's no compressed gas on
the line and between the line and the product, that the gas supply is shut off, and that the possibility of turning back
on is completely prevented.
Turn off the inlet and outlet valves that are located on the line at the back and the front of the regulator. Release the
compressed gas that has accumulated between the line and the product safely and gradually through the part between
the gas pressure regulator and the outlet valve. Remove the inlet and outlet connections off the line with an
appropriate wrench without using excessive load or force. If it's going to be replaced with a new product, assemble
and set up the new product according to this manual.
9- MALFUNCTIONS, REPAIR, PROBLEMS AND SOLUTIONS
Before, during and after all malfunctions, follow the rules in the order specified on this manual and carry out the
necessary procedures. Pay special attention to informing the end users and take the necessary precautions against the
dangers of compressed gas.
End users must not carry out any repairing procedures on the product. All repairing procedures must be carried out by
authorized services and personnel. The people other than users or authorized personnel must not respond to the
product and the line in case of a malfunction.
If you suspect a malfunction, it's recommended that you carry out the procedures on Table 1 according to the type of
the problem. If you do not want to carry out these procedures, or if you cannot eliminate the problem even after you
carry them out; do not try to interfere with the product any more. Remove the product off the line according to the
rules of removal specified below without trying to open it up, send the product to our company, and install a new
product on the line. The maintenance, repairing and changing procedures must not be carried out in a way that will
interfere with the internal parts of the product.
The maintenance and repairing must be carried out on empty systems and products that have been removed off the
