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
・
Repairs or disassembly of the piping, adjustment and valve opening/
closing should be carried out only by trained maintenance personnel.
・
Before connecting piping or disassembling the product, close the inlet
and outlet valves and make every effort to reduce the internal pressure
to cool the product to room temperature.
・
When disassembling connecting parts, remove pipes and bolts slowly to
prevent condensate from suddenly flowing out in the event of residual
pressure inside the product.
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.
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
“Maintenance
Space and Tolerance Angle for Installation
”), 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:
Also replace any gaskets, units or parts that are broken or show serious wear. If any
parts require replacement, refer to “Replacement Parts”.
When reassembling, coat threads and bolts with anti-seize. Tighten the body and
cover bolts left and right in a uniform manner, 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 in this Instruction Manual.
