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
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.)
