Disassembly/Reassembly
Warning
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.
Caution
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.
Use the eye bolts for removing the cover only; DO NOT use the eye bolts for hoisting the
product. Eye bolts may break under strain, possibly resulting in serious injury.
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.)
