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.
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.
Be sure to use only the recommended components when repairing the
product, and NEVER attempt to modify the product in any way.
Failure to observe these precautions may result in damage to the product or
burns or other injury due to malfunction or the discharge of fluids.
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.)
