INSTALLATION, OPERATION & MAINTENANCE MANUAL (IOM) IOM-PBE-H
12-13
1. An inlet block valve should always be installed.
2. If service application is continuous such that
shut down is not readily accomplished, it is rec-
ommended that an inlet block valve, outlet block
valve, and a manual bypass valve be installed.
3. Pipe unions should be installed to allow removal
from piping.
4. An outlet pressure gauge should be located ap-
proxi mately ten pipe diameters downstream, and
within sight.
5. All installations should include a downstream
safety re lief de vice if the inlet pressure could
exceed the pres sure rating of any downstream
equip ment or the maximum outlet pressure rating
of the unit.
6. Clean pip ing of all foreign material including chips,
welding scale, oil, grease and dirt before installing
the reg u la tor. Strainers are rec om mend ed.
7. In plac ing thread seal ant on pipe ends pri or to
en gage ment, ensure that excess material is re-
moved and not allowed to enter regulator upon
startup.
8. Flow Direction: Install so the fl ow direction match-
es the arrow cast on the main regulator body.
9. For best performance, install in well drained hori-
zon tal pipe.
10. Recommended installation is with spring cham-
ber hanging directly be low the body in a ver ti cal
down wards orientation. Allows water to drain; etc.
11. Regulators are not to be buried un der ground.
12. For insulated piping systems, recommendation is
to not insulate regulator.
CAUTION
Installation of adequate overpressure pro tec tion is recom-
mended to pro tect the reg u la tor from overpressure and
all down stream equip ment from damage in the event of
regulator failure.
