question. lest say you have a 5 port Samsung but you only use 3 ports, can you at a later date hook up a 4th line set for another indoor unit? would you need to add valves to the spare ports at initial install to facilitate this or does the unit shut off the ports that aren't being used?

[@TaddyDigest]

Yes at a later date you can add another indoor unit No you do not have to add any valves

I have this split system but seems like indoor units thermostat is very offset. Showing 68 while every other indoor thermometer shows 72-74. Any idea how to fix this?

[@mikefarah5752]

It it normal for these units to have some oil in the lines and pressure when opening the port for the first time to make my flare connections? (I know the indoor units come charged with nitrogen)

[@TaddyDigest]

always open the vapor line 1st Are you asking is it normal

[@mikefarah5752]

Jw if is normal on the outdoor unit to have a little fluid in the lines? (First time open the port to make my connections)

I have a 3 ton fjm, 2, 18k heads and a 7 head. Line sets were run years ago. The 7 head has a 1/2 od line and a 1/4. I have my longest run in head on bottom or port e, 2nd 18 head on port d and the 7k head is on port c. Went through auto addressing, let unit do its thing. Went inside and tried running 18k unit on port d and get an error code e465 and e464. Any advice or information will be greatly appreciated. Thank you
