Proper Installation of X-element
Install the spring clip securely in the

• 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 to room temperature. Failure
to do so may result in burns or injury.
• Be sure to use the proper components and NEVER attempt to modify
the product.
