4 Ton Multipoise Fan Coil, Two Stage, R-454B, Variable Speed, 208/1

The FG5 is the premium air handler combining the proven technology of  Carrier fan coils with environmentally balanced R-454B refrigerant.

The FG5 achieves an operational advantage when the variable speed  ECM (Electronically Commutated Motor) is combined with a  heat  pump or air conditioner with refrigerant. 

With attention to quiet, efficient, and comfortable operation, Carrier has  developed a new benchmark for superior indoor comfort and control.  Carrier’s heat pump and air conditioning systems feature R-454B, the  chlorine-free refrigerant that is the future for the residential heating and  cooling industry. The FG5 using R-454B refrigerant maximizes  performance for environmentally balanced systems. In addition to  environmental safety, these systems are 30 to 40% more efficient than  standard heating and cooling systems, thereby combining excellence in  efficiency and environmental responsibility.

The FG5 provides these benefits due to Carrier’s command of ECM  technology. These motors are extremely efficient at all speeds, and  enable the FG5 to operate at the correct speed to deliver airflow  precisely, ensuring proper performance across a wide range of duct static  pressures. This adaptive efficiency also makes installation quality easier  to achieve for today’s demanding homeowner.

Carrier’s command of ECM technology may be most evident in the  comfort advantages that ECM can deliver. Operation set up steps on the   Board provide the installing technician with alternatives to maximize  comfort and efficiency. For true indoor comfort, the homeowner can  achieve command of both temperature and humidity in cooling and  heating modes.

Another feature which sets the FG5 apart is the factory-installed TXV,  which enhances efficiency and provides compressor protecting operation  at all recommended conditions. Grooved tubing, louvered aluminum  fins, and the large face areas of the FG5 refrigerant coils also provide  superior efficiency, for high SEER and HSPF performance. Carrier leads  the way in condensate control, a hallmark of these multipoise fan coils.  All of these featured components are protected within a rugged,  

pre-painted metal cabinet lined with super thick, high density insulation.  For neat, high quality installations the unit exterior features sweat  refrigerant connections for simple leak free performance, and multiple  electrical entry for both high and low voltage service.

Assembled at the factory compliant with low leak requirements of less  than 2% cabinet leakage rate at 1 inches W.C. and 1.4% cabinet leakage  rate at 0.5 inches W.C. when tested in accordance with ASHRAE 193  standard.
