Daikin approves alternative pipework materials for installation

Daikin has approved the use of alternative pipework materials when installing their equipment, clearing the way for installation of Reflok systems

After a long period of discussion, trials and consultation between Reflok and Daikin, the manufacture has now approved the use of alternative pipework materials when installing their equipment.

In a statement Reflock said: “This is great news for Reflok who has been approached many times by contractors asking if use of its pipe system would invalidate the Daikin’s warranty terms.

On the day Daikin approved the use of alternative pipework a contractor immediately ordered Reflok for an installation.

Daikin identified that the use of alternative materials for jointing and piping is growing within the industry.

They also recognised that these products can enable the reduction or elimination of hot works on site which can be a requirement of the customer’s specifications.

Reflok has a range of fittings that allow direct connection to Daikin’s Refnets allowing a true ‘heat free’ installation.”

Daikin will continue to maintain its manufacturers warranty on systems using these alternative methods providing the following criteria are met:-

  • Any system piping or jointing materials & methods must meet all local and European legislation, including F-Gas obligations to minimise or eliminate the possibility of refrigerant leaks, and the safety and environmental requirements of BS-EN378
  • Any damage directly or indirectly caused to the installed Daikin system through installation or use of these methods or materials will not be covered by the Daikin warranty, this includes increased wear and tear on the system caused by a lack of refrigerant.
  • All Refnet joints used on Daikin systems must be original Daikin supplied parts, this is to ensure correct system pressure, oil and gas distribution. The use of third party refnets, Y or T pieces is not supported and could invalidate the warranty
  • Any materials used should not increase the pressure drop or introduce any foreign substances into the refrigerant circuit when compared to the recommended refrigerant grade copper mentioned in the relevant Daikin installation manuals.
  • Any installation using different pipework materials (i.e. Cu to Al) must use a system that prevents any dielectric / bi-metal / galvanic corrosion from occurring through the operational life of the system including maintenance and service activities.
