FE4A/FE5A Air Handler Features

Smart Diagnostics
 Self configuring (ease of installation)
 Easier troubleshooting, providing faster service and repair
Environmentally--Sound Refrigerant Technology
Puron refrigerant the chlorine--free non--ozone depleting refrigerant
 Thermostatic Expansion Valve (TXV) designed to maximize performance with Puron refrigerant
Energy Efficient Operation
 Electronically Commutated Motor (ECM) operates efficiently at all speeds
 Maximizes efficiency of heating and cooling systems
 Ultra--low power consumption during fan only operation
Comfort Control
 Warm, comfortable heating air temperatures
 Unmatched humidity control
Airflow and Sound Technology
 Logarithmic spiral blower housings for high blower efficiency and quiet operation
 Diffuser air discharge section for high airflow efficiency and quiet, smooth operation
 High duct static capability
 Unique cabinet design that meets new stringent regulations for air leakage. Meets requirements of a 2% cabinet leakage rate when tested at 1.0 in 
 wc of static pressure.
Condensate Control and Disposal Technology
Minimal standing water -- less microbial growth for improved IAQ and reduced condensate line clogging and related condensate leakage
Condensate fittings relocated away from turbulent airflow patterns at the blower entrance for improved condensate control performance
Overflow feature for slope coil units allows condensate to exit the unit without damage to product under clogged primary and secondary line conditions
Tested for condensate disposal at conditions much more severe than those required by ARI
Primary and secondary drain connections to comply with HUD
All pans constructed of an injection molded glass--filled polycarbonate engineered resin material, with brass drain connections
High density, super thick cabinetry insulation with vapor barrier
Pre--painted galvanized sheet metal cabinet
Heat Transfer Technology
