ment, exploded views and specifications.
Points to be observed
Observe the following points during maintenance work:
•
Observe instructions in this manual for maintenance, inspection, dismantlement and as
-
sembly. Do not dismantle the pump beyond the extent of the instructions.
• Always wear protective clothing such as an eye protection, chemical resistant gloves, a
mask and a face shield during disassembly, assembly or maintenance work. The spe

cific solution will dictate the degree of protection. Refer to MSDS precautions from the
solution supplier.
•
Risk of electrical shock. Be sure to turn off power to stop the pump and related devices
before service is performed.
Before unplugging the pump:
Always stop the pump by key operation and wait for three seconds, especially when
disconnecting the pump from a piping system. Otherwise, the stop command may not be
saved, and the pump may unintentionally start to run and deliver fluid into an imperfect
piping system as it is powered on once again.
NOTE

condition.
• Contact your distributor or a manufacturer of the host machine in which our product is built for repair.
• Be sure to drain chemicals and flush the inside of the pump before return so that a harmful chemical does not
spill out in transit.
