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.)
