1.INTRODUCTION
Throughout this manual there are a number of HAZARD
WARNINGS that must be read and adhered to in order to
prevent possible personal injury and/or damage to equi-
pment. Three signal work “DANGER”, “WARNING” and
“CAUTION” are used to indicate the severity of a hazard,
and are preceded by the safety alert symbol.
Danger Denotes the most serious hazard and is
used when serious injury or death WILL result from misuse
or failure to follow specic instructions.
Warning Used when serious injury or death MAY
result from misuse or failure to follow specic instructions.
Caution Used when injury or product/equipment
damage may result from misuse or failure to follow specic
instructions.
Caution It is the responsibility and duty of
Warning all personnel involved in the installation,
Danger operation and maintenance of the equi-
pment on which this device is used, to fully understand the
procedures by which hazards can be avoided.
The compatibility of the product is the responsibility of
the person who designs the equipment or decides its
specications.
Only personnel with appropriate training should operate
machinery and equipment.
Do not service or attempt to remove the machinery or
equipment until safety is conrmed.
2.DESCRIPTION
Before you can feed a plant with a gaseous uid, it must be
processed to remove contaminants such as water and oil
particles, dirt and is also necessary to reduce the pressure
to the level required by the equipment downstream.
• Filters are designed to remove airborne solid and liquid
contaminants which may plug small orices and hinder
performance or cause excessive wear and premature
equipment failure.
• Regulators provide controlled, consistent air pressure as
required for specic pneumatic equipment connected to
the air system.
• Filter/regulators are designed to remove airborne solid and
liquid contaminants which may plug small orices and
hinder performance or cause excessive wear and prema-
ture equipment failure. In addition to ltration the regula-
tors portion provides controlled, consistent air pressure
as required for specic pneumatic equipment connected
to the air system
3. OPERATION
In these devices, the main spring (5) exerts a force on a
diaphragm assembly (6,7,8,9,10). This force can be adju-
sted by turning the adjustment screw (1). By readjusting
the main spring, the regulator valve assembly (16,17,18,
41) is pushed down and the seat of the lower seal is rele-
ased, while the front side of the adjusting piston continues
to be sealed by the element sealing in the diaphragm. This
allows the ow from the pressure to the processing lines for
the supply and exhausting of the system. Small pressure
uctuations can be compensated by slight movements of
the piston adjustment and changes of the ow on the lower
valve seat. If the pressure on the line of work exceeds the
set pressure of work, this generates a force on the lower
side of the diaphragms that pushes the diaphragm upwards,
the air then ows over the sealing element in the diaphragm
and through a light of drain on the body of the compressed
air regulator.

6.TRANSPORTATION & STORAGE
The preferred storage location is a clean, dry and protected
warehouse. If the components have to be stored outside,
precautions should be taken to keep valves clean and dry.
For storage temperatures, refer to the table in paragraph
“TECHNICAL FEATURS”.
To avoid contamination of impurities during the storage period,
don’t remove thread protection caps; remove them just before
the installation phase.
7. INSTALLATION
Warning Before performing any work, read this ma-
nual and study all gures. Assure yourself that you understand
and you can do what is required in each step. Failure to follow
these instructions may affect quick release valve operation and
may result in exposure to personal injury.
Before installing the valve, set and block the machine or equi-
pment in a secure position; close the air shutoff valve and
exhaust air from air lines and disconnect all electrical power.
• Upstream of lubricators and cycling valves
• As close as possible to the air supply when used as a main
line lter
•As close as possible to the device being serviced when used as
a nal lter
• Caution In the version with automatic drain and
with hazardous area medium but compatible with the mate-
rials, you must remember that the device is designed with
allowable leakage. In the cases, it is necessary to provide for
the conveyance of the discharge in safe area. No responsi-
bility will be charged to SITECNA to unsafe use.
8. MOUNTING
• Vertically (bowl down),
• With air ow in direction of arrow on body,
• Connect piping to proper ports using pipe thread sealant on
male threads only. Do not allow sealant to enter the unit.
• Install a pressure gauge or plug the gauge ports. Gaugeports
can also be used as additional outlets for regulated air
9. TESTING
• Before applying inlet pressure to lter/regulator, turn adjust-
ment (1) counterclockwise to remove all force on regulating
spring (5).
• Apply inlet pressure, then turn adjustment (1) clockwise to
increase and counterclockwise to decrease outlet pressure
setting.
• Always approach the desired pressure from a lower pressure.
When reducing from a higher to a lower setting, rst reduce
to some pressure less than thatdesired, then bring up to the
desired pressure.
Caution With non-relieving lter/regulators, make
pressure reductions with some air ow in the system. If
made under no ow (dead-end) conditions, the lter/regula-
tor will trap the over-pressure in the downstream line.
• Once required pressure is achieved tighten locknut (2) to
lock setting.
10. MAINTENANCE
Warning Before performing any work, read this
manual and study all gures. Assure yourself that you un-
derstand and can do what is required in each step. Failure
to follow these instructions may affect quick release valve
operation and may result in exposure to personal injury.
Before uninstalling the valve, set and block the machine or
equipment in a secure position; close the air shutoff valve
and exhaust air from air lines; disconnect electrical power.
• Filter/regulator can be disassembled without removal from
air line.
• Shut off inlet pressure. Reduce pressure in inlet and outlet
lines to zero.
• Turn adjustment screw fully counter clockwise.
• Disassemble in general accordance with the item numbers
on exploded view. Do not remove the drains unless repla-
cement is necessary. Remove and replace drains only if
they malfunction.
A.Ordinary maintenance
Caution The FR, F and R should be periodically
checked for proper functioning:
• Clean the FR, F and R from impurities and dirt;
• Visually check of the integrity of the body and cup of FR,
F and R;
• Check that there aren’t leakages;
• Check the correct functionality of the FR, F and R;
• For manual drain models, regularly open drain to expel
accumulated liquids. Keep liquids below lter element (21)
• At approximately 6 month intervals it is advisable to remove
the bowl assembly by removing the securing screws (27)
and unscrewing the lter element (21) for inspection;
• Clean or replace lter element when dirty.

11. MARKING ACORDING TO 2014/34/UEAtex
For using these equipment in potentially explosive atmo-
spheres, it is recommended - for the installation and the
maintenance operation - to use tools and instruments that
can produce only a single spark (for instance: screwdrivers,
spanners). Avoid use of tools that can produce sparks like
disk saw or grinder
Action must be taken to put to earth the units through a su-
itable connection, checking that all the metal components
(ttings and pipe line) have to be equitable potential.
Equipment have to be installed in the corresponding zone
according to the marking.
