The trap should
preferably be installed in the horizontal plane, with a small drop leg
preceding it. Where the trap discharges into a closed return system,
a non-return valve should be fitted downstream to prevent return flow.
Ensure all connection ports are clear from any obstruction. Always
open isolation valves slowly until normal operating conditions are
achieved. This will avoid system shocks. Check for leaks and correct
operation. Always ensure correct tools, safety procedures and protective
equipments are used at all times. |
