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 44 lb
(20 kg) 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
Do not use excessive force when connecting threaded pipes to the
product. Over-tightening may cause breakage leading to fluid
discharge, which may cause burns or other injury.
CAUTION
Use the procedures on the following pages 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.)
In cases where sufficient maintenance space has been provided for (see “Installation
and Maintenance Space”), maintenance can be carried out without disconnecting the
inlet and outlet piping. Where there is insufficient maintenance space, first disconnect
the inlet and outlet piping, and then move the unit to a spacious area in which
maintenance can be carried out safely.
When reassembling:
•
Be sure to replace the body and cover gaskets with new gaskets. Also replace any
parts that are broken or show serious wear.
•
When reassembling, coat threads and bolts with anti-seize. Tighten the cover bolts
in a symmetrically alternating pattern, being careful to avoid uneven tightening.
•
If drawings or other special documentation were supplied for the product, any
torque given there takes precedence over values shown here.
