THE EXPRESS WARRANTY SET FORTH ABOVE CONSTITUTES

INCLUDING ANY WAR RANTY OF MERCHANTABILITY OR

Safe Operation (See also Bulletin RSBCV)
People doing any work on a refrigeration system must be
qualifi ed and completely familiar with the system and the
Refrigerating Specialties Division Products involved, or all
other precautions will be meaningless. This includes reading
and understanding pertinent Refrigerating Special ties Division
Product Bulletins, and Safety Bulletin RSB prior to installa tion
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.
