Maintenance and Part Replacement
Use hoisting equipment for heavy objects (weighing approximately
20 kg or more). Failure to do so may result in back strain or other injury if
the object should fall.
CAUTION
NEVER apply direct heat to the float. The float may explode due to
increased internal pressure, causing accidents leading to serious injury
or damage to property and equipment.
WARNING
When disassembling or removing the product, wait until the internal
pressure equals atmospheric pressure and the surface of the product
has cooled to room temperature. Disassembling or removing the
product when it is hot or under pressure may lead to discharge of fluids,
causing burns, other injuries or damage.
CAUTION
Be sure to use only the recommended components when repairing the
product, and NEVER attempt to modify the product in any way. Failure to
observe these precautions may result in damage to the product or burns
or other injury due to malfunction or the discharge of fluids.
CAUTION
Make sure the power supply is OFF before carrying out work on the
wiring or inspections involving disassembly. If such work is carried out
with the power on, there is a danger that equipment may malfunction or
electric shock may occur, leading to injury or other accidents.
CAUTION
Make sure that wiring work requiring a special license is carried out only
by qualified personnel. If carried out by unqualified personnel,
overheating or short circuits leading to injury, fires, damage or other
accidents may occur.
CAUTION
When using this product, NEVER stand close to, or leave tools anywhere
near, moving parts, such as the shaft. Contact with moving parts or
objects becoming caught in moving parts could lead to injury or
damage or other accidents.
CAUTION
Installation, inspection, maintenance, repairs, disassembly, adjustment and valve
opening/closing should be carried out only by trained maintenance personnel.
Replaceable parts
Refer to the instruction manual for the pump unit.
On maintenance inspection, alignment of the pump and motor should be checked. The
alignment should be within 5/100 mm axially and radially at the coupling.
