Note: Gripping or bending the connecting tube will damage it and reduce
performance of the pump.
Note: After removing the pump head, lay it on a soft cloth.
Note: There is a thing that the pump head spacer has been inserted under the pump
head. ( Photo 6 and 7) After Diaphragms is exchanged, the pump head spacer is
installed in the same part. Identify it so as not to confuse it.
Note:
It marks the pump head spacer. Marking is used to identify the thickness, and
there are each red, blue, and a black. Note that it influences the performance
when making a mistake as former position.
