Installation
WARNING
!
Only qualied 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 uid 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 uid 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
Specications 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
uid. 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 anged
bodies, use suitable line gaskets and approved
piping and bolting practices. Install the regulator
in any position desired, unless otherwise specied,
but be sure ow through the body is in the direction
indicated by the markings on the body.
1. The pressure/temperature limits in this Installation Guide and any applicable standard or code limitation should not be exceeded.

Type 1301
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
trafc 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.
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
To change the outlet pressure, 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. Tighten the locknut 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.
