PED Conformity Statement and Information

Types CS800, CS804, CS820, CS824, CS850 and

CS854 are in conformity with the Pressure Equipment

Directive PED 97/23/EC and are classied under

Category I for units without a slam-shut and Category IV

for units with a slam-shut. See Table 2.

For Types CS800, CS820 and CS850, equipment and

pipeline situated on outlet side of the regulator are either

- not subject to the PED (PS ≤ 0.5 bar) or

- subject to (PS > 0.5 bar) in which case they should

come under Category I maximum

WARNING

Failure to follow these instructions or to

properly install and maintain this equipment

could result in an explosion and/or re

causing property damage and personal injury

or death.

Fisher

regulators must be installed, operated

and maintained in accordance with federal,

state and local codes, rules and regulations

and Emerson™ instructions.

If the regulator vents gas or a leak develops in

the system, service to the unit may be required.

Failure to correct trouble could result in a

hazardous condition.

Call a gas service person to service the

unit. Only a qualied person must install or

service the regulator.

Description

CS800 Series regulators are typically installed on industrial

and commercial applications. See Table 1 for available

congurations. Constructions with External Registration,

e.g., Type CS800EN, require an external control line.

The CS800 Series offers multiple forms of overpressure

protection including:

Internal Relief - Minimizes downstream pressure buildup

by relieving gas through the diaphragm assembly and

out the 1 NPT vent to atmosphere in the event of an

overpressure situation.
