Prerequisite: Turn OFF the respective circuit breaker.
1 Wait for the refrigerant to reach the outdoor temperature.
2 Connect a manometer to the service port.
3 Measure the pressure of the refrigerant. The measured
pressure MUST be in line with the expected pressure at outdoor
temperature.
4 If the measured pressure is higher than the expected pressure
(at outdoor temperature), other non‑condensables are mixed in
the refrigerant.
Any non‑condensables found
in the refrigerant circuit?
Action
Yes To replace the refrigerant, see
"3.2.2Repair procedures"on
