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.
WARNING
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.
CAUTION
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
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.)
