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 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 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 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.
Warranty
All Refrigerating Specialties Products are warranted against defect in
workmanship and materials for a period of one year from date of

which have been altered or repaired in the field; damaged in transit,
or have suffered accidents, misuse, or abuse. Products disabled by
dirt, or other foreign substances will not be considered defective.
THE EXPRESS WARRANTY SET FORTH ABOVE CONSTITUTES
THE ONLY WARRANTY APPLICABLE TO REFRIGERATING
SPECIALTIES PRODUCTS, AND IS IN LIEU OF ALL OTHER
WARRANTIES, EXPRESSED OR IMPLIED, WRITTEN OR ORAL,
INCLUDING ANY WARRANTY OR MERCHANTABILITY, OR
