Just immediately look up the manual and go step by step. Not really difficult for a new unit. Basically set outside bracket and extension arms. Looking forward to it. May buy 2 more this week after testing 1. Question for those with multiple. Can you control more than 1 with App. That feature was a seller for me as we are not home a lot and I need to keep the pups cool especially big boy who hates heat. Being a St Bernard Husky it's understandable. Will sleep in the snow at 0⁰ though. Dog like owner I guess.
