VRV outdoor unit location

Hi,

We are working on a VRV system (Myself for first time).

Wanted to know minimum clearance required between wall and outdoor unit for having proper amount of air volume flow rate through outdoor units.

Units are located on an exterior overhang and one side is wall while other three sides are open.

Thanks

Vijay Kumar

Minimum clearence is 300 mm in this case. And 400 mm between 2 outdoors. This information should be in Installation Manual of VRV.
