Warnings
Warnings in this manual provide information needed for safe operation of the pump, and instructions for
preventing danger or injury to you or other people. So that you will know the degree and imminence of
danger that warnings signify, they are divided into two grades, WARNING and CAUTION, according to the
seriousness of what will happen if their instructions are not heeded. Both grades of warning contain
important safety information; carry out all the instructions that they give, without fail.
