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
reading and understanding pertinent Refrigerating
Specialties Division product Bulletins and Safety Bul-
letin RSB prior to installation or servicing work.
Where cold refrigerant liquid lines are used, it is neces-
sary 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, or regulators
with electric shutoff, 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 refriger-
ant 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 no suitable for am-
monia service.
