Safe Operation (See also Bulletin RSB)
People doing any work on a refrigeration system must be
qualified and completely familiar with the system and the
Refrigerating Specialties Division valves involved, or all
other precautions will be meaningless. This includes read-
ing and understanding pertinent Refrigerating Specialties
Division product Bulletins and Safety Bulletin RSB prior to
installation or servicing work.
Where cold refrigerant liquid lines are used, it is necessary that
certain precautions be taken to avoid damage that could result
from liquid expansion. Temperature increase in a piping section
full of solid liquid will cause high pressure due to the expanding
liquid that can possibly rupture a gasket, pipe or valve. All hand
valves isolating such sections should be marked, warning
against accidental closing, and must not be closed until the liquid
is removed. Check valves must never be installed upstream of
solenoid valves, or regulators with electric shut-off, nor should
hand valve upstream of solenoid valves or downstream of check
valves be close until the liquid has been removed. It is advisable
to properly install relief devices in any section where liquid
expansion could take place.
Avoid all piping or control arrangements that might produce
thermal or pressure shock. For the protection of people and
products, all refrigerant must be removed from the section to
be worked on before a valve, strainer, or other device is opened
or removed. Flanges with ODS connections are not suitable for
ammonia service.
