Safety information, installation and maintenance For full details see the Installation and Maintenance Instructions (IM-S32-04) supplied with the product. Warning
Under certain conditions corrosive elements in condensate can affect the inside face of the sight tube, particularly where caustic alkali and hydrofluoric acid are present. It is recommended that the sight check is periodically checked for thinning of the sight tube. If there is evidence of thinning or erosion damage then the sight tube should be replaced immediately. Always wear eye protection when viewing the contents of the sight check. Installation and maintenance note: The sight check should have stop valves fitted on both the inlet and outlet. It is imperative that the upstream stop valve is closed first in order to prevent over pressurisation. Sight checks can be fitted in either a horizontal or a vertical line on the outlet side of the steam trap. Where the trap is a blast discharge type e.g. thermodynamic, the sight check must be fitted at least 1 m (3.28 ft) from the trap. This is to ensure that the glass tube is not subjected to thermal shock or pressure. Reasonable steps should be taken to protect personnel from injury in the unlikely event that the glass breaks. Ensure access is available to enable the withdrawal of the discharge tube. Disposal This product is recyclable. No ecological hazard is anticipated with disposal of this product providing due care is taken.
