To ensure a secure and compliant installation of the Cyclone fitting into the QB1-21XE WWHR unit, please follow the updated guidance below:
- Do not use silicone spray, grease, or any other lubricant when fitting the Cyclone. These substances reduce the friction between the O-rings and the inner surface of Showersave, which may lead to air test failures.
- Use clean water only to lightly moisten the O-rings. Then, insert the Cyclone into the WWHR pipe using a slow, twisting action. This should be done before mounting the unit to the wall, allowing for visual inspection to confirm correct alignment and seal.
- Using water ensures the O-rings seat correctly and create an airtight seal, helping you avoid any issues during air testing.
As stated in Part H of the Building Regulations (Page 12, Fig 1.38): “The pipes, fittings and joints should be capable of withstanding an air test of positive pressure of at least 38mm water gauge for at least 3 minutes.”
Failure to follow this guidance may compromise the seal and result in the unit failing the required air test.
If you have any questions regarding this process, please don’t hesitate to contact us.
