Before attempting any maintenance 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 product, 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.
2. General product information 2.1 General description The Spirax Sarco 200 series of cast iron inverted bucket steam traps are designed for installation in vertical pipework with the flow vertically upwards.

3. Installation Note: Before actioning any installation observe the 'Safety information' in Section 1. Referring to the Installation and Maintenance Instructions, name-plate and Technical Information Sheet, check that the product is suitable for the intended installation: Check materials, pressure and temperature and their maximum values. If the maximum operating limit of the product is lower than that of the system in which it is being fitted, ensure that a safety device is included in the system to prevent overpressurisation.

Under low load and / or low pressure applications the discharge may tend to 'dribble'. Condensate is discharged at steam temperature so due care must be given to the site of the discharge.
6. Maintenance Note: Before actioning any maintenance programme observe the 'Safety information' in Section 1. Warning The cover gasket contains a thin stainless steel support ring which may cause physical injury if not handled and disposed of carefully. It is recommended that new gaskets and spares are used whenever maintenance is undertaken.
Always order spare parts by using the description given in the column headed 'Available spares' and state the size and full definition of the trap eg. 223/16. Example: 1 - Valve and seat assembly for a Spirax Sarco DN25, 223/16 (having a DPMX of 8.5 bar g) cast iron inverted bucket steam trap.
