Safety information Safe operation of these products can only be guaranteed if they are 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. 1.1Intended use Referring to the Installation and Maintenance Instructions, name-plate and Technical Information Sheet, check that the product is suitable for the intended use / application. The products listed below comply with the requirements of the European Pressure Equipment Directive 97 / 23 / EC and carry the mark when so required. It should be noted that products rated as 'SEP' are required by the Directive not to carry the mark. The products fall within the following Pressure Equipment Directive categories: IBV size Group 1 Gases Group 2 Gases ½" and ¾" DN15 and DN20 2 1 1" DN25 3 2 1½" and 2" DN40 and DN50 3 2 3" DN80 4 3 Group 1 Liquids Group 2 Liquids i) The product has been specifically designed for use on steam, air or water / condensate which are in Group 2 of the above mentioned Pressure Equipment Directive. The products’ use on other fluids may be possible but, if this is contemplated, Spirax Sarco should be contacted to confirm the suitability of the product for the application being considered. ii) Check material suitability, pressure and temperature and their maximum and minimum values. If the maximum operating limits of the product are lower than those of the system in which it is being fitted, or if malfunction of the product could result in a dangerous overpressure or overtemperature occurrence, ensure a safety device is included in the system to prevent such over-limit situations. iii)Determine the correct installation situation and direction of fluid flow. iv)Spirax Sarco products are not intended to withstand external stresses that may be induced by any system to which they are fitted. It is the responsibility of the installer to consider these stresses and take adequate precautions to minimise them. v) Remove protection covers from all connections and protective film from all name-plates, where appropriate, before installation on steam or other high temperature applications. 1.2Access Ensure safe access and if necessary a safe working platform (suitably guarded) before attempting to work on the product. Arrange suitable lifting gear if required. 2 IM-P067-11 ST Issue 1 1.3Lighting Ensure adequate lighting, particularly where detailed or intricate work is required. 1.4Hazardous liquids or gases in the pipeline Consider what is in the pipeline or what may have been in the pipeline at some previous time. Consider: flammable materials, substances hazardous to health, extremes of temperature. 1.5Hazardous 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. 1.6The system Consider the effect on the complete system of the work proposed. Will any proposed action (e.g. closing isolation valves, electrical isolation) put any other part of the system or any personnel at risk? Dangers might include isolation of vents or protective devices or the rendering ineffective of controls or alarms. Ensure isolation valves are turned on and off in a gradual way to avoid system shocks. 1.7Pressure systems Ensure that any pressure is isolated and safely vented to atmospheric pressure. Consider double isolation (double block and bleed) and the locking or labelling of closed valves. Do not assume that the system has depressurised even when the pressure gauge indicates zero. 1.8Temperature Allow time for temperature to normalise after isolation to avoid the danger of burns. 1.9Tools and consumables Before starting work ensure that you have suitable tools and / or consumables available. Use only genuine Spirax Sarco replacement parts. 1.10Protective clothing Consider whether you and / or others in the vicinity require any protective clothing to protect against the hazards of, for example, chemicals, high / low temperature, radiation, noise, falling objects, and dangers to eyes and face. 1.11 Permits to work All work must be carried out or be supervised by a suitably competent person. Installation and operating personnel should be trained in the correct use of the product according to the Installation and Maintenance Instructions. Where a formal 'permit to work' system is in force it must be complied with. Where there is no such system, it is recommended that a responsible person should know what work is going on and, where necessary, arrange to have an assistant whose primary responsibility is safety. Post 'warning notices' if necessary. IM-P067-11 ST Issue 1 3 1.12Handling Manual handling of large and / or heavy products may present a risk of injury. Lifting, pushing, pulling, carrying or supporting a load by bodily force can cause injury particularly to the back. You are advised to assess the risks taking into account the task, the individual, the load and the working environment and use the appropriate handling method depending on the circumstances of the work being done. 1.13Residual hazards In normal use the external surface of the product may be very hot.

Operation Under most conditions the trap will discharge condensate with a 'blast' type action. 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. 4. 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: 1. 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 over-pressurisation. 2. Determine the correct installation situation and the direction of fluid flow. 3. Remove protective covers from all connections. 4. The trap must be installed with the body upright so that the bucket is rising and falling vertically. The inlet should be at the bottom with the trap installed below the drain point so that a water seal can be maintained around the open end of the bucket. When superheat conditions exist the trap body may need to be primed with water prior to steam being turned on to avoid steam blowing through the trap. Inverted bucket steam traps do not permit rapid release of air. On process applications, in particular, this can lead to slow warm-up times and waterlogging of the steam space. A separate external air vent is therefore required in parallel to vent air efficiently. Any bypass should be positioned above the trap. If it is below, and is leaking or left open, the waterseal could be blown away leading to steam wastage. Where inverted bucket traps are fitted in exposed conditions the possibility of freezing damage can be reduced by thermal insulation. Air vent Fig. 2 Typical application IBV IBV Note: If the trap is to discharge to atmosphere ensure it is to a safe place, the discharging fluid may be at a temperature of 100°C. 5. Commissioning After installation or maintenance ensure that the system is fully functioning. Carry out tests on any alarms or protective devices. 20 IM-P067-11 ST Issue 1 6. Maintenance Note: Before actioning any maintenance observe the 'Safety information' in Section 1. General note - On the cover of the IBV there in a " hole, threaded and plugged, to eliminate any water discharge after being hydraulically tested before leaving the factory. This hole can be reopened on site for the customer to perform periodic hydro testing. " plug 2 Safety note: The body / cover gasket contains a thin stainless steel support ring which may cause physical injury if not handled and disposed of carefully. Before undertaking any maintenance on the trap it must be isolated from both the supply line and return line and any pressure allowed to safely normalise to atmosphere. The trap should then be allowed to cool. When reassembling, ensure that all joint faces are clean. 6.2 How to fit the valve and seat assembly: - Disconnect the outlet connection and after 11 7 10 9 13 6 8 12 Bucket and Valve assembly 6.1 3 4 undoing the cover bolts (3) remove the cover (2) and valve seat (11) together with bucket assembly from the body (1). - Unhook the bucket (6) from the valve lever (13). - Remove the bracket (7) by undoing the two screws (8). - Remove the valve seat (11). The valve seat is spherically ground so that a seal is made at the sealing face. When fitting a new valve seat, it is extremely important to ensure that the joint faces are clean, and STAG jointing compound should be applied to the threaded portion. -Screw in a new valve seat (11), to the recommended torque (see Table 1, page 10). - Fit a new bracket and valve lever (7 + 13), 1 using new screws (8) supplied. Tighten these after checking that the valve head (12) is properly aligned to the valve seat orifice (11). - Hook the bucket (6) onto the valve lever (13). - Using a new gasket (4), refit the cover to the recommended torque, see Table 1, page 22 and reconnect the outlet to the pipework.
