Disassembly/Reassembly
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.
Use hoisting equipment for heavy objects (weighing approximately 20 kg (44
lb) or more).
Failure to do so may result in back strain or other injury if the object should fall.
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.
Use the following procedures to remove components. Use the same procedures in
reverse to reassemble. (Installation, inspection, maintenance, repairs, disassembly,
adjustment and valve opening/closing should be carried out only by trained
maintenance personnel.)
