  • Page 15 that the outdoor unit is below the indoor unit. Calculate the corrected capacity of MSAN8-Y 160M (“C”) by using K1: C = B × K1 = 16.75 × 0.927 =15.53kW  The corrected capacity 15.53 kW is lower than required total heat load 16.5kW, so selection is complete. (In the event that the corrected capacity is lower than the required total heat load, Step 3 should be repeated from the point where the outdoor unit capacity is provisionally selected.)
