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.)
NOTE: This section explains disassembling and reassembling of the bimetal unit only. For other
parts, refer to page 10 to page 11.
9.2 Disassembly/Reassembly
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.
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.
