The Daikin indoor unit FXAQ shall be completely factory assembled and <br />tested. Included in the unit is factory wiring, piping, electronic proportional <br />expansion valve, control circuit board, fan motor thermal protector, flare <br />connections, condensate drain pan, self- diagnostics, auto - restart function, <br />3- minute fused time delay, and test run switch. The unit shall have an auto - <br />swing louver which ensures efficient air distribution, which closes automati- <br />cally when the unit stops. The remote controller shall be able to set five (5) <br />steps of discharge angle. The front grille shall be easily removed for wash- <br />ing. The discharge angle shall automatically set at the same angle as the <br />previous operation upon restart. The drain pipe can be fitted to from either <br />left or right sides. <br />2. Indoor unit and refrigerant pipes will be charged with dehydrated air prior <br />to shipment from the factory. <br />3. Both refrigerant lines shall be insulated from the outdoor unit. <br />4. Return air shall be through a resin net mold resistant filter. <br />5. The indoor units shall be equipped with a condensate pan. <br />6. The indoor units shall be equipped with a return air thermistor. <br />7. The indoor unit will be separately powered with 208- 230V/1- phase /60Hz. <br />8. The voltage range will be 253 volts maximum and 187 volts minimum. <br />D. Unit Cabinet: <br />1. The cabinet shall be affixed to a factory supplied wall mounting template <br />and located in the conditioned space. <br />2. The cabinet shall be constructed with sound absorbing foamed polysty- <br />rene and polyethylene insulation. <br />E. Fan: <br />1. The fan shall be a direct -drive cross -flow fan, statically and dynamically <br />balanced impeller with high and low fan speeds available. <br />2. The fan motor shall operate on 208/230 volts, 1 phase, 60 hertz with a <br />motor output range 0.054 to 0.058 HP. <br />3. The airflow rate shall be available in high and low settings. <br />4. The fan motor shall be thermally protected. <br />F. Coil: <br />1. Coils shall be of the direct expansion type constructed from copper tubes <br />expanded into aluminum fins to form a mechanical bond. <br />2. The coil shall be of a waffle louver fin and high heat exchange, rifled bore <br />tube design to ensure highly efficient performance. <br />3. The coil shall be a 2 -row cross fin copper evaporator coil with 14 fpi de- <br />sign completely factory tested. <br />4. The refrigerant connections shall be flare connections and the conden- <br />sate will be 11/16 inch outside diameter PVC. <br />5. A thermistor will be located on the liquid and gas line. <br />6. A condensate pan shall be located in the unit. <br />G. Electrical: <br />1. A separate power supply will be required of 208/230 volts, 1 phase, 60 <br />hertz. The acceptable voltage range shall be 187 to 253 volts. <br />2. Transmission (control) wiring between the indoor and outdoor unit shall <br />be a maximum of 3,280 feet (total 6,560 feet). <br />3. Transmission (control) wiring between the indoor unit and remote control- <br />ler shall be a maximum distance of 1,640 feet. <br />Reece, Noland & McElrath, Inc. 239500-53 Orange County Board of Elections <br />Orange Co., NC 05/04/18 <br />
