I have a split type air conditioner made by Mitsubishi. I

I have a split type air conditioner made by Mitsubishi. I was just wondering whether after connecting the copper tubing if there is a valve to open for the refrigerant or does it open automatically? It seems the air should be a little cooler and I was afraid I missed possibly turning a valve.JA: Did you double-check the thermostat's settings? And what about the filters?Customer: It is controlled by a remote and I do have the remote on 18 degrees C (I think 60 degrees F) The unit is new so the filters are okayJA: Do you plan on doing the work yourself?Customer: Yes...I installed the unit and everythings seems to be working correctly, but feels it should be a little cooler.JA: Anything else we should know to help you best?Customer: The outside unit does go off with the inside unit running....probably to save electricity. But, shouldn't the condenser be operating most of the time to generate the cool air...or is it primarily the inside evaporating unit?
