Proof Test Pressure

All Pressure Retaining Components have been
proof tested per Directive 97/23/EC - Annex 1,
Section 7.4

Temperature Capabilities

Nitrile/Neoprene: -40 to 82°C (-40 to 180°F)
Fluoroelastomer: -18 to 149°C (0 to 300°F)  hot
water limited to 82°C (180°F)

Installation

Only qualified personnel should install or service
a regulator.  Regulators should be installed, oper-
ated, and maintained in accordance with interna-
tional 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 imme-
diately may create a hazardous condition.

Personal injury, equipment damage, or leakage
due to escaping fluid or bursting of pressure-con-
taining parts may result if this regulator is over-
pressured or is installed where service condi-
tions could exceed the limits given in the Specifi-
cations section, or where conditions exceed any
ratings of the adjacent piping or piping connec-
tions.

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 lim-
its.

Additionally, physical damage to the regulator
could result in personal injury and property dam-
age due to escaping fluid.  To avoid such injury
and damage, install the regulator in a safe loca-
tion.

1.  Optional low gain restriction for liquid service and/or broader proportional bands or
high gain restriciton for narrower proportional bands (such as low-differential boiler
fuel service).
2.  The pressure/temperature limits in this installation guide and any applicable
standard or code limitation should not be exceeded.
