Hello, I have a question regarding Guijitsu Mini split system.
I installed everything according instructions except Air Pumping and as I was reading It's required. All valves have not been opened yet. However, I tested indoor unit (turned it on) and it's working fine as fan As there is no cooling going into pipes. I will try to pump air out and check all pipe connections. But I noticed that outside unit doesnt start/work or anything. So the question is ..

Is it normal for outside unit to be silent/inactive until valves are opened?

I am hoping after purging air it will work
