chains or cables are wrapped around
the pump to lift it, make certain that they
are positioned so as not to damage the
pump, and so that the load will be bal

After the pump has been installed, make
certain that the pump and all piping or
hose connections are secure before op
eration. Loose connections can result in
damage to equipment and serious inju
ry to personnel.
