COMMUNICATING VARIABLE SPEED FAN COIL PURON® REFRIGERANT

PREMIUM ENVIRONMENTALLY SOUND

The FE4A is the premium air handler combining the proven technology of Bryant fan coils with the environmentally sound refrigerant, Puron®. The FE4A achieves an operation advantage because the ECM (Electronically Commutated Motor) combined with a Quantum Plus heat pump with Puron is highly efﬁcient at all possible operating speeds, and delivers the precise amount of airﬂow desired over a wide range of duct static pressure conditions.

The FE4A comes with state of the art smart diagnostics capability. This enables faster troubleshooting providing ease of service and repair. The FE4A also provides a 4-wire hook up with matching outdoor unit and the Evolution Control. This makes installation simpler and a lot quicker than with conventional fan coils. The FE4A’s advanced technology allows the fan coil to self-conﬁgure with a matching outdoor unit and the Evolution Control, cutting down on installation time.

Other features homeowners appreciate are quiet operation of the FE4A, including the soft ramp up at the beginning of a heating or cooling cycle, and its soft ramp down when the duty cycle is complete. Annoying sounds from sudden changes in airﬂow are reduced for worry free comfort. When used in continuous fan mode, the FE4A can operate quietly at very low levels of airﬂow for gentle reduction of temperature differences between areas of the home and within each individual room from ﬂoor to ceiling. In addition, when used in conjunction with Bryant air cleaners, the FE4A provides continual cleansing of the air while quietly operating in continuous fan duty, for the best in indoor air quality.

The FE4A is loaded with other popular features. The Thermostatic Expansion Valve (TXV) reliably meters refrigerant at all operating conditions during cooling mode providing excellent compressor protection. Grooved copper tubing, louvered aluminum ﬁns, and the large face areas of the FE4A refrigerant coils provide superior efﬁciency, for high SEER and HSPF performance. Robust, corrosion resistant and highly draining condensate pans provide for excellent condensate control. All components are protected within a rugged, prepainted metal cabinet lined with super thick, high density insulation and vapor barrier. The unit exterior features sweat

refrigerant connections for simple leak free performance, multiple electrical entry for both high and low voltage service to simplify installation. Field-installed heaters are also available, ranging from 5-kw to 30-kw.

For the best in efﬁciency and Environmentally Sound operation, comfort, ease of installation and reliable performance, the FE4A can’t be beat.

PERFORMANCE DATA

AIRFLOW DELIVERY — COOLING, HEATING, ELECTRIC HEATING MODES

The FE4 fan coil will provide airﬂow at a rate that is requested by the Integrated System User Interface during Air Conditioning or Heat Pump Heating (without electric heat) modes. The nominal airﬂow for both heating and cooling modes is 350 cfm/ton nominal refrigeration size of the outdoor unit installed. The airﬂow actually requested by the User Interface is modiﬁed by its internal algorithms for zoning, comfort or efﬁciency concerns.

Refer to the documentation for the User Interface for more information on how the User Interface controls the fan coil. Safe operation of electric heaters requires airﬂow delivery at or above the minimum CFM for electric heater application listed in the chart below.

ACCESSORY KITS DESCRIPTION

SUGGESTED AND REQUIRED USE

Disconnect Kit

The kit is used to disconnect electrical power to the fan coil so service or maintenance may be performed safely.

SUGGESTED USE: FE4 units with 3- through 10-kW electric resistance heaters and cooling controls.

2. Downﬂow Conversion Kit Fan coils are shipped from the factory for upﬂow or horizontal-left applications. Downﬂow conversion kits provide proper condensate water drainage and support for the coil when used in downﬂow applications. Separate kits are available for slope coils and A-coils.

REQUIRED USE: This kit must be used whenever FE4 fan coils are used in downﬂow applications.

3. Downﬂow Base Kit This kit is designed to provide a 1-in. minimum clearance between unit discharge plenum, ductwork, and combustible materials. It also provides a gap free seal with the ﬂoor.

REQUIRED USE: This kit must be used whenever FE4 fan coils are used in downﬂow applications.

4. Single-Point Wiring Kit The single-point wiring kit acts as a jumper between L1 and L3 lugs, and between L2 and L4 lugs. This allows the installer to run 2 heavy-gage, high-voltage wires into the fan coil rather than 4 light-gage, high-voltage wires.

SUGGESTED USE: FE4 fan coils with 15- and 20-kW fused heaters only.

5. Air Cleaner 240-Volt Conversion Kit The AIRA electronic air cleaner comes ready for 115-v operation.

REQUIRED USE: This kit is required when running 240-volt circuit to air cleaner.

6. Airﬂow Sensor Kit (Air Cleaner) The airﬂow sensor kit ensures the FE4 fan coil and electronic air cleaner work as a system.

REQUIRED USE: This kit is required whenever an electronic air cleaner is used with an FE4 fan coil.

7. Fan Coil Filter Kit shipped from factory with 12 fan coil framed ﬁlters. These ﬁlters collect large dust particles from the return air entering the fan coil and prevents them from collecting on the coil. This process helps to keep the coil clean, which increases heat transfer and in turn the efﬁciency of the system.

SUGGESTED USE: For replacing factory-supplied ﬁlters (same ﬁlters).

8. Condensate Drain Trap Kit This kit consists of 50 PVC condensate traps. Each trap is pre-formed and ready for ﬁeld installation. This deep trap helps the system make and hold proper condensate ﬂow even during blower initiation.

SUGGESTED USE: FE4 fan coils.

9. Downﬂow/Horizontal Conversion Gasket Kit This kit provides the proper gasketing of units when applied in either a Downﬂow or Horizontal application.

REQUIRED USE:

FE4 fan coils.
