Before assembly/disassembly
• Inch the motor or rotate the motor fan by hand to extend the pump shaft to the maximum length when remov
-
ing the diaphragm.
• Inch the motor or rotate the motor fan by hand to contract the pump shaft to the minimum length when replac
-
ing the pump head to the bracket.
• When a new diaphragm is mounted, clean the diaphragm-side retainer surface and apply the grease; Dow
Corning Toray MOLYKOTE® HP-500. Always apply a screw burning protective agent to the diaphragm shaft.
• Observe the mounting direction of the valve assembly. If the outlet valve assembly is mounted upside down,
the pump falls into closed-discharge operation and excessive pressure may damage the pump or cause per
-
sonal injury when it bursts.
• Always fasten the pump head to the specified tightening torque (see the exploded view pages) in diagonal
order. Repeat the procedure once again to make sure the possibility of a leak is eliminated.
