5.3 Disassembly/Reassembly
Before disassembling the pump, make certain the power supply (circuit
breaker, etc.) is turned off. Then, unplug the cable assembly from the
receptacle or detach it from the terminals. 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 Wacker 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.
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 Wacker representative in
the event such repairs are necessary.
