8.1 Precautions for disposal
When detaching the pump from the equipment for disposal or replacement of the pump, be sure to turn off
the main power in advance.
Warning
Before detaching the pump, turn off the main power without fail.
Failure to observe this may lead to a danger because the pump may
suddenly start in automatic operation or on other occasions.
Caution
When lifting the pump, pay attention to its center of gravity. Failure to
observe this may cause the product to topple over or fall down, leading to
an injury.
(1) Drain the liquid from the tank (oil tank) so that the bottom of the pump is exposed above the
liquid level.
(2) Close the sluice valve on the discharge side and open the air vent valve of the pump to
discharge the liquid from the pump.
(3) Remove the wiring and piping. (For the layout in the terminal box, refer to Section “3.3
Precautions for installation”, (page 3-2).)
(4) Remove the pump mounting bolts and lift up the pump by the ropes passed through the lifting
holes. Because the liquid remaining in the pump may flow out during pump removal and
movement, take measures against it as needed.
Caution
Do not hold the strainer on the tip of the pump during handling. Failure to
observe this may cause the strainer to come off, resulting in an injury or
breakage.
(5) The pump should be disposed of as industrial waste. Other parts should be disposed of
according to the legal regulations and the regulations of the region where they are used, e.g.
requesting the vendor to dispose of.
Note
When disposing of the pump, treat it as industrial waste.
Note
The packing materials that became unnecessary after installation and the
lubricating oils and parts that became needless in maintenance, check and
repair work should be disposed of according to the legal regulations and
the regulations of the region where they are used, e.g. requesting the
vendor to dispose of.
