P.E.D. Categories
This product may be used as a pressure accessory with
pressure equipment in the following Pressure Equipment
Directive. For information on the current PED revision see
Bulletin: D103053X012. Pressure regulator does not require
any supplementary upstream safety accessory for protection
against overpressure compared with its design pressure
PS, when upstream reducing station is sized for a maximum
downstream incidental MIPd <= 1.1 PS.

Table 7c. North American Overpressure and Underpressure Shut-off UPSO/OPSO Ranges
Table 7d. European Overpressure and Underpressure Shut-off UPSO/OPSO Ranges
Example: If a non-standard setpoint is needed, see the following example for the proper use of Tables 7a, 7b, 7c and 7d. In this
example, the non-standard regulator setpoint is 140 mbar / 2.0 psig. The minimum factory token relief set pressure is 130% of the
non-standard setpoint. The resulting token relief set pressure is 183 mbar / 2.6 psig. The minimum factory OPSO and UPSO set
pressures are 165% and 50% of the non-standard setpoint, respectively. The resulting minimum settings are: OPSO = 231 mbar /
3.4 psig and UPSO = 70 mbar / 1.0 psig.

Downstream Control Line Installation
!
WARNING
Failure to install a downstream control line
could result in a hazardous condition. Install
downstream control line(s) to the slam-shut
device when construction uses external
pressure registration. The regulator and
slam-shut device will not control pressure
or shut off if a downstream control line is
not installed on those constructions where
external pressure registration is required.
CSB700 Series regulators with an “ET” or “EN” in the type
number use external pressure registration. To communicate
the downstream pressure to the regulator, connect a
downstream control line tubing to the 3/4 NPT control line
tapping in the lower diaphragm casing and connect the other
end of the tubing downstream of the regulator outlet with a
minimum distance of 6 times the outlet pipe diameter.
For all types with external control lines, use tubing with an
inner diameter of 16 mm / 0.63 in. or larger.
Downstream Control Line Installation with
Slam-Shut Device
Refer to Figure 1. When installing the Types CSB704ET,
CSB704FET, CSB704FEN CSB704EN, CSB724ET,
CSB724EN, CSB724FEN and CSB754EN regulators,
connect downstream control line tubing to the lower casing
of the regulator and run the tubing downstream of the
regulator outlet with a minimum distance of 6 times the outlet
pipe diameter. Connect a second, separate downstream
control line tubing to the lower casing of the slam-shut and
run the tubing downstream of the regulator outlet a minimum
distance of 6 times the outlet pipe diameter.
For all types with external control lines, use tubing with an
inner diameter of 16 mm / 0.63 in. or larger for the primary
regulator and 6.4 mm / 0.25 in. or larger for the slam-shut.
Installation with External Overpressure Protection
If the regulator is used in conjunction with a Type 289H
relief valve, it should be installed as shown in Figure 6.
The outside end of the vent line should be protected
with a rainproof assembly. The Type 289H is typically
set 25 mbar / 10 in. w.c. higher than the outlet pressure
setting of the regulator, up to 75 mbar / 30 in. w.c. outlet
pressure. For pressure greater than this, set the Type 289H
0.05 bar / 0.73 psi higher than the outlet pressure setting
of the regulator. Refer to the 289 Series Instruction Manual
(D100280X012) for more information.
Installation
!
WARNING
Only qualified personnel shall install or
service a regulator. Regulators should
be installed, operated and maintained
in accordance with international and
applicable codes and regulations and
Emerson instructions.
If the regulator vents fluid or a leak develops
in the system, it indicates that service
is required. Failure to take the regulator
out of service immediately may create a
hazardous condition.
Personal injury, equipment damage or
leakage due to escaping gas or bursting of
pressure containing parts may result if this
regulator is overpressured or is installed
where service conditions could exceed the
limits given in the Specifications section or
where conditions exceed any ratings of the
adjacent piping or piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices (as required by the appropriate code,
regulation or standard) to prevent service
conditions from exceeding limits.
Additionally, physical damage to the
regulator could result in personal injury and
property damage due to escaping fluid. To
avoid such injury and damage, install the
regulator in a safe location.
Clean out all pipelines before installation of the regulator
and check to be sure the regulator has not been damaged
or has collected foreign material during shipping. For NPT
bodies, apply pipe compound to the external pipe threads.
For flanged bodies, use suitable line gaskets and approved
piping and bolting practices. Install the regulator in any
position desired, unless otherwise specified, but be sure flow
through the body is in the direction indicated by the arrow on
the body.
Note
It is important that the regulator be installed
so that the vent hole in the spring case
is unobstructed at all times. For outdoor
installations, the regulator should be located
away from vehicular traffic and positioned
so that water, ice and other foreign materials
cannot enter the spring case through the
vent. Avoid placing the regulator beneath
eaves or downspouts and be sure it is above
the probable snow level.

CSB700 Series
7
Vent Line Installation
CSB700 Series regulators have a 1 NPT screened vent
opening in the spring case. If necessary to vent escaping
gas away from the regulator, install a remote vent line in
the spring case tapping. Vent piping should be as short
and direct as possible with a minimum number of bends
and elbows. The remote vent line should have the largest
practical diameter. Vent piping on regulators with token relief
must be large enough to vent all relief valve discharge to
atmosphere without excessive backpressure and resulting
excessive pressure in the regulator.
For types with optional token relief, this low capacity relief
is located in the spring case of the primary regulator. If
necessary to vent escaping gas away, install a remote vent
line in the spring case tapping of the primary regulator as
described above. Periodically check all vent openings to be
sure that they are not plugged or obstructed.
For Types CSB700/CSB700F/CSB720/CSB720F, outlet
pressure higher than 0.34 bar / 5.0 psig above the setpoint
may damage internal metallic parts. For Type CSB750,
outlet pressure higher than 1.5 bar / 21.8 psig above the
setpoint may damage internal metallic parts.
Overpressure Protection
The recommended pressure limitations are stamped on
the regulator nameplate. Some type of overpressure
protection is needed if the actual inlet pressure exceeds the
maximum operating outlet pressure rating. Overpressure
protection should also be provided if the regulator inlet
pressure is greater than the safe working pressure of the
downstream equipment.
Regulator operation below the maximum pressure limitations
does not preclude the possibility of damage from external
sources or debris in the line. The regulator should be
inspected for damage after any overpressure condition.
Startup
The regulator is factory set at approximately the midpoint
of the spring range or the pressure requested, so an initial
adjustment may be required to give the desired results.
With proper installation completed and relief valves properly
adjusted, slowly open the upstream and downstream
shutoff valves.
Adjustment
Note
For types that include the slam-shut module,
refer to the instruction manual for Type VSX8
slam-shut for adjustment and maintenance
of the slam-shut.
To change the outlet pressure, loosen the hex nut and turn
the adjusting screw clockwise to increase outlet pressure or
counterclockwise to decrease it. Monitor the outlet pressure
with a test gauge during the adjustment. Tighten the hex nut
to maintain the desired setting.
Taking Out of Service (Shutdown)
!
WARNING
To avoid personal injury resulting from
sudden release of pressure, isolate
the regulator from all pressure before
attempting disassembly.
