Reliable equipment care starts with regular observation and an appropriate response. Use this guide as general education, then follow manufacturer instructions and seek qualified advice for your particular site.
Possible signs of a leak
Poor cooling, longer operating cycles, ice in unexpected places or oily residue around a connection can indicate a problem, but these symptoms have other causes too. Proper diagnosis requires qualified testing.
Why topping up is not the fix
A correctly operating sealed system should not routinely lose refrigerant. Adding charge without finding and repairing the leak wastes money, can damage equipment and may breach environmental requirements.
What to do
Keep people away if there is a strong unusual odour, visible damage or concern about a large release in an enclosed space. Ventilate only when safe to do so, isolate equipment if advised and contact an appropriately licensed technician.
Prevention through maintenance
Regular inspection can detect rubbing pipework, vibration, corrosion and deteriorating joints. Service records also help technicians recognise repeated loss and choose a durable repair.
Never bypass a safety device or attempt electrical or refrigerant work unless you are properly qualified and authorised. Protect people first.
