The installation of this ultra low ambient kit allows for cooling operation down to -40°F outside temperatures. It is an excellent option for commercial applications, especially in Northern regions of the US, that require cooling year round. Some examples that require year-round cooling may include server rooms, production facilities and even restaurants.
This ultra low ambient kit is specifically for use with the FTXS36LVJU / RKS36LVJU 36000 BTU Cooling Only 17.9 SEER Sky Air Mini Split. The kit installs easily by adding the circuit board to modify the control sequences, a crankcase heater (included) and outdoor wind baffle (KPW5E80 sold separately).
