The regulator does not require any mainte-
nance. Nevertheless, it is subject to natural
wear, particularly at the seat, plug and oper-
atingdiaphragm/bellows.Dependingonthe
operating conditions, check the regulator at
regular intervals to avoid possible malfunc-
tions. Operators 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qualied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 specied 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 specied tightening torques
(see Annex).
Risk of regulator damage due to the use of
unsuitable tools.
Î Only use tools approved by SAMSON
(see Annex).
Risk of regulator damage due to the use of
unsuitable lubricants.
Î Only use lubricants approved by
SAMSON (see Annex).
