The performance chart will vary depending onthe indoor unit type.• Check each performance value in test-run mode. Electrical performance values represent a combined indoor/outdoor value.(In this case, be sure to stop all the indoor units where performance is not being checked.)• The performance is for a tubing length of 24.6t (7.5m). If the tubing length is different, the performance chart will vary.NOTELow pressure at wide tube service valvepsig (MPaG)High pressure at wide tube service valvepsig (MPaG)Outdoor air temperature °F (°C) Outdoor air temperature °F (°C)174(1.2)188(1.3)160(1.1)146(1.0)77(25) 86(30) 95(35) 104(40) 23(-5) 32(0) 41(5) 50(10) 59(15) 68(20) 77(25)23(-5) 32(0) 41(5) 50(10) 59(15) 68(20) 77(25)23(-5) 32(0) 41(5) 50(10) 59(15) 68(20) 77(25)Lo fan Hi fan HH fan 506(3.5)434(3.0)362(2.5)290(2.0)Operating current (A)Operating current (A)Outdoor air temperature °F (°C) Outdoor air temperature °F (°C)4532Lo fan Hi fan HH fan7865Indoor discharge air temperature °F (°C)Indoor discharge air temperature °F (°C)Outdoor air temperature °F (°C) Outdoor air temperature °F (°C)46.4( 8)68.0(20)64.4(18)60.8(16)57.2(14)53.6(12)50.0(10)77(25)131(55)140(60)122(50)113(45)104(40)95(35)86(30)Lo fan Hi fan HH fanOutdoor Unit CU-3KE19NBU Indoor Unit CS-MKE7NKU×15-1-1.
