    1.9 Tools and consumables Before starting work ensure that you have suitable tools and / or consumables available. Use only genuine Spirax Sarco replacement parts. 1.10 Protective 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.
  • Page 6 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.

    The installation of an appropriately sized safety valve, to protect any lower pressured equipment on either the hot or cold side of the plate heat exchanger, is strongly recommended. Spirax Sarco supplies a range of traps, strainers, separators, safety valves and pressure reducing equipment. 3.2 Air supply If a pneumatic control system is installed, connect a compressed air supply (65 to 116 psi g) to the pressure regulator mounted on the control valve.
