1. Safety information Safe operation of these products can only be guaranteed if it is properly installed, commissioned, used and maintained by qualified personnel (see Section 1.11 ) in compliance with the operating instructions. General installation and safety instructions for pipeline and plant construction, as well as the proper use of tools and safety equipment must also be complied with. 1.
1.5 Hazardous environment around the product Consider: explosion risk areas, lack of oxygen (e.g. tanks, pits), dangerous gases, extremes of temperature, hot surfaces, fire hazard (e.g. during welding), excessive noise, moving machinery. 1.6 The system Consider the effect on the complete system of the work proposed. Will any proposed action (e.g.
1.13 Residual hazards In normal use the external surface of the product may be very hot. If used at the maximum permitted operating conditions the surface temperature of some products may reach temperatures in excess of 570°C (1058°F). Many products are not self-draining. Take due care when dismantling or removing the product from an installation (refer to ‘Maintenance instructions’). 1.
2. General product information 2.1 General description The Spirax Sarco HP80, HP100, HP150 and HP210 bimetallic steam traps are made of forged steel, and designed for draining high pressure, high temperature steam lines and processes. These steam traps, which are specially designed for HP steam, have a reinforced stainless steel insert within the body and can be repaired online.

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: 3.1 Check materials, pressure and temperature and their maximum values.
4. Commissioning After installation or maintenance ensure that the system is fully functioning. Carry out tests on any alarms or protective devices. Note: During commissioning the valve may need resetting to take account of any backpressure in the return line. 5. Operation The Spirax Sarco HP80, HP100, HP150 and HP210 are bimetallic steam traps.
Maintenance note: Maintenance can be completed with the trap in the pipeline, once the safety procedures have been observed. It is recommended that new gaskets and spares are used whenever maintenance is undertaken. Ensure that the correct tools and necessary protective equipment are used at all times. When maintenance is complete open isolation valves slowly and check for leaks. 6.1 Trap seat flushing during operation This maintenance operation should be performed once every six months.
6.4 Disassembly and service 1. Shut the trap inlet and discharge valves, vent the pressure and allow the trap to cool sufficiently to prevent possible injury from hot surfaces. 2. Remove the blind nut (11). 3. Remove the six cover nuts (9) and the cover (8). 4. Remove the strainer screen (4) and clean or replace. 5. Note: The valve and bimetallic element assembly (3) is assembled loosely. Carefully lift these as one piece from the body (1).
6.5 Reassembly: Refer to Figure 4, page 13. 1. Place the check valve spring and ball (13 and 14) into the body (1) and position them properly. 2. Use a high temperature thread lubricant on the valve seat (12), adjustment screw threads and gasket seating surfaces. Put the valve seat gasket (2) in place and thread the valve seat (12) into the body (1). Tighten to the recommended torque as specified, in Table 1, page 9. 3. Install the valve opening spring. 4.
7. Spare parts The spare parts available are detailed in the table below. No other parts are supplied as spares. Available spares Bimetallic assembly kit 2, 3, 4, 7, 10, 12 Check valve assembly 13, 14 Strainer screen 4 Cover gasket set (packet of 3) 7 2, 7, 10 Gasket set How to order spares Always order spares by using the description in the column headed 'Available spares' and state the size and model of the bimetallic steam trap.
8. Fault finding 1. Make sure upstream and downstream valves are open. 2. Check external strainers for clogging; blowdown or dismantle and clean. Trap fails to pass condensate 3. Valve port clogged with dirt. Follow 'Trap seat flushing' procedure (See Section 6.1). 4. Bimetallic element improperly adjusted. Adjust as described under 'Trap discharge temperature adjustment' (See Section 6.2). 5. Dismantle and inspect internals. See 'Disassembly and service' (See Section 6.4). 1. Dirt on seating surface.
