This symbol → indicates a change since the last issue. SAFETY CONSIDERATIONS Improper installation, adjustment, alteration, service, maintenance, or use can cause explosion, fire, electrical shock, or other conditions which may cause personal injury or property damage. - Page 2 FV4B Fan Coils can be installed for upflow and horizontal-left applications as factory shipped. (See Fig. 2, 4 and 8.) Units can be installed for horizontal-right applications with field modifications. Units may be converted for downflow applications using factory-authorized accessory kits.

- Page 6 Duct connection flanges are provided on unit air discharge connection. When using FV4B units with 20-, 24-, and 30-kw electric heaters, maintain a 1-in. clearance from combustible materials to discharge plenum and ductwork for a distance of 36 in. from unit. Use accessory downflow base to maintain proper clearance on downflow installations.

- Page 10 (See Fig. 17 and 18.) The FV4B Fan Coil must be configured to operate properly with system components with which it is installed. To successfully configure a basic system (see information printed on circuit board label located next to select pins), move the 6 select wires to the pins which match the components used.

- Page 13 I. COMFORT OPTIONS - WARMER HEATING AND SUPER DEHUMIDIFY (See Fig. 21 for Quick Reference Guide) The FV4B Fan Coil provides better than average humidity control and heated air temperature. This configuration will improve the comfort provided by the heat pump system if more humidity removal or if warmer heating air is desired. While providing this improved comfort, the heat pump system will operate efficiently, but not at the published HSPF or ARI SEER efficiency.
- Page 14 The AUX1 and AUX2 terminals are not always energized during blower operation, as described above. When using an electronic air cleaner with the FV4B Fan Coil, use Airflow Sensor Part No. KEAAC0101AAA. The airflow sensor turns on electronic air cleaner when the fan coil blower is operating.
- Page 15 PROCEDURE 10—FV4B FAN COIL SEQUENCE OF OPERATION The FV4B will supply airflow in a range which is more than twice the range of a standard fan coil. It is designed to provide nominal cooling capacities at a 50°F evaporator temperature and the required airflow which enables it to match with 4 air conditioner or heat pump system sizes.
