  • FETA Application based DSEAR Risk Assessment GuidesNo.1: Installation of an R32 Split Air Conditioning System.
  • FETA Guidance on Risk Assessments for compliance with DSEARFollowing the publication of our introduction to A2L refrigerants, a number of FETA groups have been working on guidance for the industry with regard to Risk Assessments required for compliance with DSEAR – the Dangerous Substances and Explosive Atmospheres Regulation. With the growing use of a number of refrigerants which exhibit flammability to various degrees, this is a topic area which may be new to many working in the industry. It should be noted that DSEAR now applies to ALL RACHP installations; not just those using flammable refrigerants.





A2L Refrigerants: Concept and Application Guide for Refrigeration Systems in the Scope of EN 378

This Guide covers the application of A2L refrigerants in refrigeration systems which are within the scope of EN 378. It does not cover air conditioning and heat pump systems and it does not cover small (integral) systems which are within the scope of a product standard. It is not a complete design guide. The Guide takes a risk assessment based approach – the hazards of A2L refrigerants are identified and the methods of mitigating these hazards are covered, in this case by following the appropriate standard (EN 378). A Quick Start Guide has also been written to cover the basics of the topic.

PLEASE NOTE previously published as a 9 part guide, with the exception of parts 2,3 and 9, the other sections are being withdrawn as commercial sites are now working to their own specifications. Parts 2,3 and 9 will be kept up to date as reference guides for commercial systems.

  • HEVAC Installation frame for fire dampers In the early 1980's HEVAC produced a specification for the construction and installation of installation frames for fire dampers. After nearly 20 years of working with the same specification, the HEVAC Fire & Smoke Damper Committee issued a new specification in 2002 and again in 2012 - HEVAC6/5/83 rev2.
  • Safe handling of refrigerants The downloadable file is a position paper from the HEVAC Air Conditioning Group. They are of the view that companies should embrace the existing voluntary ACRIB scheme now, so that companies are prepared when the mandatory scheme comes in. This would help to avoid bottle-necks in training and registration when the mandatory scheme starts.
  • HEVAC Standard Response to Subcontractor/Supplier Assessment Request The HEVAC association has produced a questionnaire for member companies on which to present their company details and capabilities to potential customers. Entitled ‘Standard Response to Subcontractor/ Supplier Assessment Request’, the seven page document provides a standard format to enter your company information that includes, insurance details, QA policy, environmental policy, health and safety and company references among other details needed by potential clients.
  • Rating scales of Seasonal Efficiency of Chillers - Seasonal Efficiency Ratings for Non-domestic HVAC Plant The report brings together the thinking behind the project, the development of the rating systems and the description of the schemes. The report will be used by the project team to publicise the rating schemes to a wider audience, and thereby promote their adoption. It is intended that it can be used by each of the partners to be placed on websites and used more in technical papers such as CIBSE or the Building Services Journal.
  • Guidance Note on the use of E-Procurement, including reverse bid auctions for HVACR products in the construction industry The HEVAC Association actively supports e-commerce activities. Within this context e-procurement, which is progressively being used more frequently by customers and member companies alike, can be viewed as a valuable tool within an organisation’s purchasing strategy.

  • HEVAC Guide to Good Practice: Air Handling Units - 1991Air handling units vary greatly in size, function and complexity. Whether they be small or large, simple or complex, there are certain points to observe and pitfalls to avoid. It was the aim of this publication to guide the reader towards good practice, so that when the unit is installed it will perform in accordance with expectations. The components most commonly utilised within air handling units are dealt with individually and for each heading there has been gathered a list of do's and don'ts distilled from many years of experience. Fans though are not covered specifically since there is a separate HEVAC Fan Application Guide which should be referred to. With such an immense variety within the scope of air handling units the topics cannot be completely comprehensive, however, the m

  • SCA/FMA Best Practice Guide to Smoke extract fan maintenanceEmergency use fans for heat and smoke control systems are specifically designed and manufactured for safety critical applications. Harmonized standards of these regulations define a list of critical components. Repair and replacement of the defined critical components shall only be carried out by the manufacturer’s authorized representative. For fans certified by a notified body, the substitution of a critical component by an alternative version of this component, must be approved by the notified body. A BSI working group (FSH/25), with its members drawn from manufacturers, installers, test establishments and motor manufacturers, was formed to examine the key issues associated with smoke extract fans. The key objective of this guide is to raise awareness of the need to ensure that any
