4. Disassembly and Assembly
- 40 -
Caution
• When disassembling the pump, put a mark on each lead in order to prevent the pump
from reversing rotation after rewiring, if you disconnect leads from the motor.
• Since the magnet used in the pump is very powerful, be careful not to get your fingers
caught between the elements during the disassembly and assembly processes. Also,
pay attention to prevent metal pieces or metal powder from adhering onto the pump.
• Do not bring any electronic device that may be impacted by strong magnetic power into
the pump magnetic field.
• Prior to disassembly or assembly, close the suction valve and discharge valve fully.
• The piping and the pump often retain liquid. When a dangerous liquid is handled, wear
protectors (goggles, rubber gloves, etc.) when disconnecting the pipes.
