To ensure safety of personnel, proper care should be used when handling assemblies and components. Many
assemblies are heavy. The assistance of another person, lifting device, or other support equipment may be
required to move or position heavy items.
Personnel must remove all items of jewelry ( rings, bracelets, watches, necklaces etc) and loose clothing before

When performing maintenance on the water system, keep in mind that the purpose of the equipment is to store
