8.1 Precautions for disposal
Before detaching the pump from the system for disposal or replacement, be sure to turn off the main
power.
Warning
Before detaching the pump, be sure to turn off the main power. Otherwise,
the pump may suddenly start up in automatic mode or on other occasions,
thus leading to great danger.
Caution
When hoisting the pump, pay attention to its center of gravity. Otherwise,
the pump may topple over or fall, thus leading to an injury.
(1) Drain liquid from the tank (oil tank) so that the bottom of the pump is exposed above the liquid
level.
(2) Shut the sluice valve on the discharge side, disconnect piping on the discharge side, and then
discharge liquid from the pump.
(3) Disconnect the wiring and piping. (For the layout in the terminal box, refer to “Section 3.5.
Precautions for wiring work [page 3-5].”)
(4) Remove the pump mounting bolts and then hoist the pump. (Refer to “Section 3.3. Precautions for
installation [page 3-2].”)
Because the liquid remaining in the pump may flow out while the pump is detached or moved, take
measures against it as needed.
(5) Dispose of the pump as industrial waste. Dispose of other parts according to your national and
local laws and regulations, for example, by asking the specialized waste disposal contractor.
Note
Dispose of the pump as industrial waste.
Note
For the packing materials that are no longer necessary after installation as
well as for used lubricating oils and parts that are no longer necessary after
maintenance, inspection, repairs, and replacement, dispose of them
according to your national and local laws and regulations, for example, by
asking the specialized waste disposal contractor.
