Safety instructions and measures
Safety features
TheType1,Type4andType4uRegulatorsdonothaveanyspecialsafetyfeatures.When
relievedofpressure,theType1andType4Regulatorsareopenedbytheforceoftheset
pointsprings.Whenrelievedofpressure,theType4uRegulatorisclosedbytheforceofthe
set point springs in the reversing device.
Responsibilities of the operator
Operators are responsible for proper use and compliance with the safety regulations. Opera-
tors are obliged to provide these mounting and operating instructions as well as the refer-
enced documents to the operating personnel and to instruct them in proper operation. Fur-
thermore, operators must ensure that operating personnel or third parties are not exposed to
any danger.
Operatorsareadditionallyresponsibleforensuringthatthelimitsfortheproductdenedin
the technical data are observed. This also applies to the start-up and shutdown procedures.
Start-up and shutdown procedures fall within the scope of the operator's duties and, as such,
are not part of these mounting and operating instructions. SAMSON is unable to make any
statements about these procedures since the operative details (e.g. differential pressures and
temperatures) vary in each individual case and are only known to the operator.
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
wellasthereferenceddocumentsandobservethespeciedhazardstatements,warnings
and caution notes. Furthermore, operating personnel must be familiar with the applicable
health, safety and accident prevention regulations and comply with them.
Referenced standards, directives and regulations
The regulators comply with the requirements of the European Pressure Equipment Directive
2014/68/EU.RegulatorswithaCEmarkinghaveanEUdeclarationofconformity,which
includes information about the applied conformity assessment procedure. This EU declaration
ofconformityisincludedinthe'Certicates'section.
AccordingtotheignitionhazardassessmentperformedinaccordancewithClause5.2of
ISO80079-36,thenon-electricalregulatorsdonothavetheirownpotentialignitionsource
even in the rare incident of an operating fault. As a result, they do not fall within the scope of
Directive 2014/34/EU.
Î Forconnectiontotheequipotentialbondingsystem,observetherequirementsspeciedin
Clause6.4ofEN60079-14(VDE0165-1).
