General safety information

Pressure

Before attempting any maintenance on the trap, consider what is or may have been in the pipeline. Ensure that any pressure is isolated and

safely vented to atmospheric pressure before attempting to maintain the steam trap. This is easily achieved by fitting Spirax Sarco

depressurisation valves type DV (see separate literature for details). Do not assume that the system is depressurised even when a pressure

gauge indicates zero.

Temperature

Allow time for temperature to normalise after isolation to avoid the danger of burns and consider whether protective clothing (including

safety glasses) is required.

Caution: The cover gasket and main valve assembly gasket may contain a thin stainless steel support ring which may cause physical injury

if it is not handled and disposed of carefully.

Installation

The trap is designed for installation with the float arm in a horizontal plane so that it rises and falls vertically, ideally with a drop leg immediately

preceding the trap. Suitable isolation valves must be installed to allow for safe maintenance/replacement. Remove all protective caps prior to

installation. Open isolation valves slowly and check for leaks. Where steam traps are fitted in exposed conditions, the possibility of freezing

damage may be reduced by thermal insulation/draining/isolation.

Maintenance

Maintenance can be completed with the trap in the pipeline, once the safety procedures have been observed. It is recommended that new

gaskets and spares are used whenever maintenance is undertaken. 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. See IM-P603-03 for further details.

Disposal

No ecological hazard is anticipated with the disposal of these products provided due care is taken.
