Contractors installed mitsubishi split ac. After incomplete installation , project took over by our department. Found following:
Indoor unit: PS 10 MYC. Outdoor unit : PU10 YAKD. (G)
When ac was started found pressures erratic.
Suction Pressure : 50 psig. Discharge pressure: 395- 430. Ambient: 106F.
Now I wonder if Indoor unit and outdoor nuit match bcoz ive seen expansion tube (1/4) in indoor and outdoor units. Just confused!!!!!!
Please, anything!!!!
