Help With Validation Issue

[qweasdd7777]

I am new at plant 3D , and I got many errors with my validation, I can not find the problem.

Can someone explain why I got the message : All components must be connected to a schematic line

What I can see is K-002 connected? 

Thanks

Equipment blocks often have multiple nozzle connections and usually you don't actually connect to them all, hence the messages...
