Introduction

This installation guide provides instructions for installation,

startup, and adjustment. To receive a copy of the instruction

manual, contact your local Fisher Sales

Office or Sales Representative or view a copy at

www.FISHERregulators.com. For further information refer to:

Type EZR Instruction Manual, form 5468, D102600X012.

The Type EZR pilot-operated, pressure reducing regula-

tors are used for natural gas, air, or other non-corrosive

gas applications and include a Type 112 restrictor and a

161EB Series or 161AY Series pilot. For applications

that have high pressure drops, using a Type 161AYM,

161EBM, or 161EBHM monitor pilot will increase the ac-

curacy of the regulator.

P.E.D. Categories

This product may be used as a safety accessory with

pressure equipment in the following Pressure Equipment

Directive 97/23/EC categories. It may also be used out-

side of the Pressure Equipment Directive using sound

Pilot Type Descriptions

Type 161AY—Low-pressure pilot with an outlet pressure

range from 15 mbar to 0,48 bar (6-inches w.c. to 7 psig).

Pilot bleeds (exhausts) downstream through the sense

(control) line.

Type 161AYM—The monitor version of the Type 161AY

pilot. The pilot bleed (exhaust) is isolated from the

sense (control) line. This pilot is used in monitoring

systems requiring an isolated pilot bleed (exhaust).

Type 161EB—High accuracy pilot with an outlet pressure

range from 0,34 to 24,2 bar (5 to 350 psig). Pilot bleeds

(exhausts) downstream through the sense (control) line.

Type 161EBM—The monitor version of the Type 161EB

pilot. The pilot bleed (exhaust) is isolated from the

sense (control) line. This pilot is used in monitoring

systems requiring an isolated pilot bleed (exhaust).

Type 161EBH—The high-pressure version of the

Type 161EB pilot with an outlet pressure range from

17,2 to 48,3 bar (250 to 700 psig).

Type 161EBHM—The high-pressure version of the

Type 161EBM pilot with an outlet pressure range from

17,2 to 48,3 bar (250 to 700 psig).

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.

1. The pressure/temperature limits in this installation guide and any applicable

standard or code limitation should not be exceeded.
