The regulator does not require any mainte-
nance. Nevertheless, it is subject to natural
wear, particularly at the seat, plug and con-
trol thermostat. Depending on the operating
conditions, check the regulator at regular in-
tervals to avoid possible malfunctions. Plant
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 appropriately
qualified to carry out such tasks.
We recommend removing the regulator from
the pipeline before performing any mainte-
nance or service work.

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.
