Safety information

Pressure

Before attempting any maintenance of the steam 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.

Allow time for temperature to normalise after isolation to avoid the

danger of burns and consider whether protective clothing (including

safety glasses) is required.

Installation

The trap is designed for installation with the capsule in a horizontal

plane and the cover at the top, preferably with a drop leg immediately

preceding the trap. When welding the trap into the pipeline, there is

no need to remove the capsule, providing the welding is done by the

electric arc method. Suitable isolation valves must be installed to

allow for safe maintenance and trap replacement. Remove all

protective caps prior to installation. Open isolation valves slowly

until normal operating conditions are achieved. Check for leaks and

correct operation.

Maintenance

Maintenance can be initiated once the safety procedures have been

observed. It is important to renew the complete assembly as there

are no servicable parts. When maintenance is complete, open

isolation valves slowly and check for leaks.

Disposal

This product is recyclable. No ecological hazard is anticipated with

the disposal of this product, providing due care is taken.
