Note: Before actioning any maintenance programme observe
the 'Safety information' in Section 1.
6.1 General information:
- Before undertaking any maintenance on the trap it must be isolated from the supply line and
any pressure allowed to safely normalise to atmosphere. The trap should then be allowed to
cool.
- When reassembling make sure that the joint faces are clean.
- maintenance can be completed with the trap in the pipeline, once the safety procedures have
been observed.
- It is recommended that the new gaskets and spares are used whenever maintenance is
undertaken (see Section 7 - Spare parts).
- Ensure that the correct tools and necessary protective equipment are used at all times.
- When maintenance is complete open isolation valves slowly and check for leaks.
