Compliance with NZS 5149
The NZS 5149 standard “dealing with refrigerant concentration in confined spaces” has been around since 2016. It’s important as it affects every new or altered DX system installed in New Zealand, but it is largely overlooked.
If you are designing or installing DX HVAC systems YOU NEED TO KNOW ABOUT NZS 5149.
