Condenser CFM & External Static Pressure
VRP is designed to install through an exterior wall with a plenum (VRPXWP*-8, VRPXWP*-14) and a Friedrich external louver .
If the Friedrich designed plenum and louver combinations are not used, the selections and design must be evaluated by Friedrich to ensure the
total pressure drop does not exceed the maximum allowable limits.
