Safety instructions and measures
1 Safety instructions and measures
Intended use
The SAMSON Type2430 Control Thermostat is a control thermostat that functions according
to the vapor pressure principle or the adsorption principle. It is used in combination with a
valve (Series43 Regulators).
The control thermostat functioning according to the adsorption principle is used for liquids,
gases and steam. The control thermostat functioning according to the vapor pressure princi-
ple (Type2430-3) is used in instantaneous water heaters. The control thermostats are used to
control the temperature of a plant in district heating supply networks to an adjusted set point.
The control thermostat is designed to operate under exactly dened conditions (e.g. operat-
ing pressure, temperature etc.). Therefore, operators must ensure that the control thermostat is
only used in operating conditions that meet the specications used for sizing at the ordering
stage. In case operators intend to use the control thermostat in other applications or condi-
tions than specied, contact SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
ÎRefer to the technical data and nameplate for limits and elds of application as well as
possible uses.
Reasonably foreseeable misuse
The control thermostat is not suitable for the following applications:
−Use outside the limits dened during sizing and by the technical data
−Use outside the limits dened by the additional ttings mounted on the control thermostat
Furthermore, the following activities do not comply with the intended use:
−Use of non-original spare parts
−Performing service and repair work not described
Safety features
The Type2430 Control Thermostat does not have any special safety features.
1-2 EB 2430 EN
Safety instructions and measures
Qualications of operating personnel
The control thermostat must be mounted, started up and serviced by fully trained and quali-
ed personnel only; the accepted industry codes and practices must be observed. According
to these mounting and operating instructions, trained personnel refers to individuals who are
able to judge the work they are assigned to and recognize possible hazards due to their spe-
cialized training, their knowledge and experience as well as their knowledge of the applica-
ble standards.
Personal protective equipment
We recommend checking the hazards posed by the process medium being used (e.g.
uGESTIS (CLP) hazardous substances database). Depending on the process medium and/
or the activity, the protective equipment required includes:
ÎProtective clothing, safety gloves and eye protection in applications with hot, cold and/or
corrosive media
ÎWear hearing protection when working near the valve
ÎCheck with the plant operator for details on further protective equipment.
Revisions and other modications
Revisions, conversions or other modications of the product are not authorized by SAMSON.
They are performed at the user's own risk and may lead to safety hazards, for example. Fur-
thermore, the product may no longer meet the requirements for its intended use.
Warning against residual hazards
To avoid personal injury or property damage, plant operators and operating personnel must
prevent hazards that could be caused in the control thermostat by the process medium, the
operating pressure or by moving parts by taking appropriate precautions. Plant operators
and operating personnel must observe all hazard statements, warning and caution notes in
these mounting and operating instructions.
Hazards resulting from the special working conditions at the installation site of the control
thermostat must be identied in a risk assessment and prevented through the corresponding
safety instructions drawn up by the operator.
We also recommend checking the hazards posed by the process medium being used (e.g.
uGESTIS (CLP) hazardous substances database).
ÎObserve safety measures for handling the device as well as re prevention and explosion
protection measures.

Safety instructions and measures
These mounting and operating instructions cover the standard version of the devices and the
standard mounting parts. Components that differ to those described in this document can be
added or removed. Refer to the mounting and operating instructions of the components not
covered in this document for the safety instructions and measures that need to be observed.
Responsibilities of the operator
Operators are responsible for proper use and compliance with the safety regulations.
Operators are obliged to provide these mounting and operating instructions as well as the
referenced documents to the operating personnel and to instruct them in proper operation.
Furthermore, 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 dened 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 specied 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 control thermostat complies with the requirements of the European Pressure Equipment
Directive 2014/68/EU. Control thermostats 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 'Certicates' section.
According to the ignition risk assessment performed in accordance with EN13463-1:2009,
section 5.2, the non-electrical control thermostats 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.
ÎFor connection to the equipotential bonding system, observe the requirements specied in
section6.4 of EN60079-14 (VDE0165-1).

Risk of personal injury through incorrect operation, use or installation as a result of
information on the control thermostat being illegible.
Over time, markings, labels and nameplates on the control thermostat may become
covered with dirt or become illegible in some other way. As a result, hazards may go
unnoticed and the necessary instructions not followed. There is a risk of personal inju-
ry.
ÎKeep all relevant markings and inscriptions on the device in a constantly legible
state.
ÎImmediately renew damaged, missing or incorrect nameplates or labels.
Risk of burn injuries due to hot or cold components and pipelines.
Depending on the process medium, the control thermostat components and pipelines
may get very hot or cold and cause burn injuries.
ÎAllow components and pipelines to cool down or warm up to the ambient tempera-
ture.
ÎWear protective clothing and safety gloves.
Risk of re or explosion as a result of hydrocarbons escaping due to leakage in the
Type2430-3 Control Thermostat or Type2403 Safety Temperature Monitor.
A small quantity of a ammable mixture of hydrocarbons is used as the operating me-
dium in the Type2430-3 Control Thermostat (vapor pressure principle) and the
Type2403 Safety Temperature Monitor (STM).
ÎMount the control thermostat and safety temperature monitor in such a way that in
the event any operating medium escapes as a result of leakage, it cannot come in-
to contact with hot surfaces, sparks, open ames or other ignition sources.
