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.
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.)

During Reassembly
Clamp Bolts 7
Clamp Nuts 6
Body Clamp 4
Loosen clamp nuts with a
tool such as an adjustable
wrench, then remove the
body clamp
When threading the clamp nut onto the clamp
bolt, the direction of the clamp nut must
be like that shown in the “Exploded View”
section on the next page. Consult the table
of tightening torques and tighten clamp nuts
to the proper torque; avoid lopsided tightening
by making sure that both sides are tightened
evenly; open inlet valve and allow live steam
to enter and heat the trap, then close the
inlet valve; after the internal and atmospheric
pressures have equalized and the trap surface
has cooled, tighten clamp nuts to the proper
torque again; Steam may leak if clamp nuts
are not re-tightened
