ISO 9001 CERTIFIED
Safe Operation (See Bulletin RSBCV)
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 reading 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 which
could result from liquid expansion. Temperature increase in a
piping section full of solid liquid will cause high pressure due
to the expanding liquid which 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 valves upstream of solenoid
valves or downstream of check valves be closed 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 which 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.
