Observe the following points during maintenance work:
• Observe instructions in this manual for maintenance, inspection, disassembly and as-
sembly. Do not take apart 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 SDS 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.

Always stop the pump by key operation and wait for three seconds, so the pump can save
the stop command for sure. If the stop command is not saved properly, the pump may
unintentionally start to run when it is powered on.
NOTE
• It's not the manufacture's responsibility for any failure due to corrosion or erosion occurred in your operating
condition.
