Installation Preparations - Mankenberg UV 5.1 ATEX H2 Betriebsanleitung

Supplement to the Operating Instructions for
Back pressure regulators UV 5.1 ATEX H2
A fitting that is operated at a medium temperature above 130°C needs undisrupted removal of
heat if it is to function perfectly.
Failure to observe this instruction may cause damage to the fitting and hence in the
caution
pipeline system as well.
» To protect internal functional parts (e.g. the seat) against damage and/or blockages, it may be necessary to
install a strainer and/or filter upstream of the fitting.
The mesh size of the sieve/filter for protecting against aggregates in the pipe section should be
selected by the plant operator according to the operating conditions.
note Failure to observe this instruction may impair the function of the fitting and lead to
damage.

7.2 Installation preparations

» It is necessary to ensure that a fitting is not installed unless its matches the operating conditions in terms of
function, pressure and temperature, range, body material as well as connection type and dimensions.
No fitting may be operated that does not have a sufficient pressure and temperature range for
the operating conditions – see section Intended use [} 6] and markings on the fitting. The
manufacturer MANKENBERG should be consulted in the case of any applications outside of
danger of
this range.
fatalities
Failure to observe this regulation may mean danger to life and limb and may cause
damage to the pressure-regulating valve.
» Newly installed tanks and pipeline sections must be thoroughly rinsed and cleaned before commissioning
» The corrosion protection for the fitting must be adapted to the local conditions.
» A pressure-regulating valve with an exposed spring must be installed in such a way that it presents no risk
of crushing to the operating personnel.
Only valves with open spring:
It is necessary to ensure on site, by an appropriate installation (e.g. not freely accessible) or
providing safety devices and/or positioning a clearly visible warning sign in accordance with
danger of
the regulations of EN 292 (formerly accident prevention regulations), that effective protection is
being
afforded against objects catching on an exposed spring in the pressure-regulating valve.
crushed
If required, MANKENBERG will assist in selecting a suitable type with closed bonnet.
Failure to observe this instruction: danger of crushing for the operating personnel
