Hello,

my english is very bad, sorry for that.

I have installed a Samsung wall unit AQV09ASAN with outdoor unit AQV09ASAX.
It's a inverter with R410a.

Sometimes at power on it showes E4 on the Display.

The manyfold says its all right but i think a little bit more R410a is required.

Is the meaning of E4 to little Refrigrant ?


Can someone give me the error code list, please?

As PM or here, thanks !!
