WARNING !
1.11 Disassembly and Reassembly
The procedure for disassembly and reassembly is shown here to the extent necessary for impeller replacement.
A specialized environment and facilities are necessary for work on the mechanical seal and the motor parts. Contact
your nearest dealer or TSURUMI representative in the event such repairs are necessary.
Before disassembling the pump, first detach the power
cable from the receptacle or terminals, after making
certain the power supply (circuit breaker, etc.) is
turned off. To avoid electrical shock, DO NOT work
with wet hands.
NEVER check the operation of any parts (impeller
rotation, etc.) by turning on the power while the unit is
partially assembled. Failure to observe these
precautions may result in a serious accident.
DO NOT disassemble or repair any parts other than
those designated here. If repairs are necessary in any
other than the designated parts, consult with your
nearest dealer or TSURUMI representative. Improper
repairs can result in electrical leakage, electrical
shock, fire, or water leaks.
After reassembly, ALWAYS perform a test operation
before resuming use of the pump. Improper assembly
will cause the pump to malfunction, resulting in electric
shock or water leaks.
