The regulator does not require any mainte-
nance. Nevertheless, it is subject to natural
wear, particularly at the seat, plug and oper-
ating diaphragm. Depending on the operat-
ing conditions, check the regulator at regular
intervals to avoid possible malfunctions. Op-
erators are responsible for drawing up an
inspection and test plan. Details on faults
and how to remedy them can be found in
the 'Malfunctions' section.
The work described in this section is only to
be performed by personnel qualified for the
assignment accordingly.
We recommend removing the regulator from
the pipeline before performing any mainte-
nance or service work.
Risk of burn injuries due to hot or cold com-
ponents and pipeline.
Regulator components and the pipeline may
become very hot or cold. Risk of burn inju
-
ries.
Î
Allow components and pipelines to cool
down or heat up.
Î
Wear protective clothing and safety
gloves.
WARNING !
Risk of personal injury due to residual pro-
cess medium in the regulator.
While working on the regulator, residual
process medium can escape and, depending
on its properties, may lead to personal in-
jury, e.g. (chemical) burns.
Î
Wear protective clothing, safety gloves
and eye protection.
Risk of regulator damage due to exces-
sively high or low tightening torques.
Observe the specified torques on tightening
regulator components. Excessively tightened
torques lead to parts wearing out quicker.
Parts that are too loose may cause leakage.
Î
Observe the specified tightening torques
(see Annex).
Risk of regulator damage due to the use of
unsuitable tools.
Î
Only use tools approved by SAMSON
(see Annex).
The regulator was checked by SAMSON
before it left the factory.
−
Certain test results certified by SAMSON
lose their validity when the regulator is
opened. Such testing includes seat leakage
and leak tests.
