Are the grohe 1405300m set service stops necessary for this unit to fuction optimally adn why?

The service stops are not required to make this operate. The service stops can be added so the water can be shut off at the valve to service it vs having to shut the main water supply to the home.

Can this be installed upside down if supply pipes are coming from above?

Hi, thank you for contacting GROHE Consumer Connections. Installing the valve upside down will also require the decorative trim plate to be installed upside down. If there is anything we can assist you with in the future, please feel free to contact us at 1-800-444-7643, Monday- Friday, 8AM- 7PM ET and a Grohe Consumer Connection Advisor will be happy to assist you.

Can this be installed on an exterior wall in Indiana?

I have not seen anything saying this is frost resistant. I would double up the wall to be safe. Basically build a wall on the inside from the insulation for where you want this. Pipes on exterior walls are a bad idea, anywhere.

does this have water restriction inside or free flow?

Hi, thank you for contacting GROHE Consumer Connections. The valve itself does not have a restrictor. If there is anything we can assist you with in the future, please feel free to contact us at 1-800-444-7643, Monday- Friday, 8AM- 7PM ET and a Grohe Consumer Connection Advisor will be happy to assist you.
