Installation
Only qualified personnel should install or service
a regulator. Regulators should be installed,
operated, and maintained in accordance with
international and applicable codes and
regulations, and Fisher 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 fluid 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 male 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.
Type VSX-2 Installation
The Type VSX-2 may be shipped separately from the
regulator. To install the unit on a regulator, place the new O-
rings (keys 2 and 3) on the Type VSX-2 and slide the module
into the regulator body. Secure the Type VSX-2 to the regulator
body with the four set screws (key 4). The unit may be oriented
in any direction with respect to the sensor line connection.

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.
Type VSX-2 Startup
The Type VSX-2 is shipped in the tripped position and will
need to be reset. If the Type VSX-2 is a high trip only, it can be
reset before starting the regulator. If the Type VSX-2 is a high
and low trip, the regulator will have to be started and the
downstream system pressurized before the Type VSX-2 can
be reset.
Adjustment
To change the outlet pressure, remove the closing cap or
loosen the locknut and turn the adjusting screw clockwise
to increase outlet pressure or counterclockwise to decrease
pressure. Monitor the outlet pressure with a test gauge
during the adjustment. Replace the closing cap or tighten
the locknut to maintain the desired setting.
Type VSX-2 Trip Adjustment
Note
An adjustment tool is included with the Type VSX-2.
Use only this tool to make adjustments to the unit.
To make adjustments, the overpressure trip spring
is found under the outer adjusting screw and the
underpressure trip spring is found under the inner
adjusting screw.
To adjust the Overpressure Trip Spring:
1. Adjust the overpressure trip setting to its maximum
compression.
2. If present, adjust the underpressure spring to its
minimum compression.
3. Backpressure the unit with the desired trip pressure.
4. Reduce the overpressure trip spring compression until
the Type VSX-2 trips.
To adjust the Underpressure Trip Spring:
1. Adjust the underpressure trip spring back to its minimum
compression.
2. Backpressure the unit with the desired trip pressure.
3. Increase the underpressure trip spring compression until
the Type VSX-2 trips.
Taking Out of Service (Shutdown)
To avoid personal injury resulting from sudden
release of pressure, isolate the regulator from all
pressure before attempting disassembly.
