Safety information, installation and maintenance
For full details see the Installation and Maintenance Instructions
(IM-S60-18) supplied with the product.
Installation note:
The strainer should be installed in the direction of

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.
Warning:
The strainer cap gasket contains a thin stainless steel support ring,
which may cause physical injury if it is not handled and disposed
of carefully.
Disposal
The product is recyclable. No ecological hazard is anticipated with
disposal of this product, providing due care is taken.
