Leakage Detection
●
Leakage detection may be identified using a leak detector.
●
Dry nitrogen pressure test maximum allowable pressure 400psi if the outdoor system is
depleted of all refrigerants during repairs.
●
Alternatively, if a leak detector is not available, apply soapy water at the suspected position of
the leak. Observe over the course of approximately 3 minutes. Emerging air bubbles will
indicate the position of the leak, should one exist.
●
Alternatively, Vacuum check, pull a deep vacuum, 200 microns as a minimum for 30 min.
