NEVER apply direct heat to the float. The float may explode due to
increased internal pressure, causing accidents leading to serious injury or
property and equipment damage.
• Installation, inspection, maintenance, repairs, disassembly, adjustment
and valve opening/closing should be carried out only by trained
maintenance personnel.
• Before attempting to open the trap, close the inlet and outlet isolation
valves and wait until the trap has cooled completely. Failure to do so
may result in burns.
• Be sure to use the proper components and NEVER attempt to modify
the product.
