Safety information, installation and maintenance

For full details see the Installation and Maintenance Instructions

(IM-S60-17) supplied with the product.

Installation note:

Suitable isolation valves must be installed to allow for safe

maintenance and trap replacement. We also recommend that a Spirax

Sarco DV depressurisation type valve (see the product specific TI

literature for further details) be installed to ensure that any pressure

is isolated and safely vented to atmospheric pressure before

attempting to maintain the strainer.

Maintenance note:

Maintenance can be completed with the strainer in the pipeline, once

the safety procedures have been observed. It is recommended that

a new gasket is used whenever maintenance is undertaken.

Disposal

The product is recyclable. No ecological hazard is anticipated with

disposal of this product, providing due care is taken.
