Check other system components for proper opera-
tion.
Check hand valves in the system to make sure they
are open or closed as required and the system is
receiving liquid or gas as the case may be.
Before disassembly of regulator, make certain that
all refrigerant has been removed (pumped out) from
the regulator and it companion strainer where one is
used. Read Safety Bulletin RSBCV.
Safe Operation (See also 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 Special-
ties Division product Bulletins and Safety Bulle-
tin 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 valve upstream of
solenoid valves or downstream of check valves be
close until the liquid has been removed. It is advis-
able 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 refrig-
erant 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.
