Assess the causeFollow the evidence.
Trace the first wet point and inspect tubing, fittings, housings, seals and inlet pressure as appropriate.
The exact model and operating conditions determine which tests apply. These are possible inspection directions, not a list of components that must be changed.
Before the appointmentKeep the useful details.
Close the inlet safely if a leak is spreading and report where it first appears.
Record the timing, previous work and accessible model label. Do not remove covers or handle live, refrigerant or pressurised components to obtain information.
