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 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

!
