Return air shall be through the concentric panel, which includes a resin <br />net mold resistant filter. <br />6. The indoor units shall be equipped with a condensate pan and conden- <br />sate pump. The condensate pump provides up to 21" of lift and has a built <br />in safety shutoff and alarm. <br />7. The indoor units shall be equipped with a return air thermistor. <br />8. All electrical components are reached through the decoration panel, <br />which reduces the required side service access. <br />9. The indoor unit will be separately powered with 208- 230V/1- phase /60Hz. <br />10. The voltage range will be 253 volts maximum and 187 volts minimum. <br />D. Unit Cabinet: <br />1. The cabinet shall be space saving and shall be located into the ceiling. <br />2. Three auto -swing positions shall be available to choose, which include <br />standard, draft prevention and ceiling stain prevention. <br />3. The airflow of the unit shall have the ability to shut down one or two sides <br />allowing for simpler corner installation. <br />4. Fresh air intake shall be possible by way of direct duct installation to the <br />side of the indoor unit cabinet. <br />5. The cabinet shall be constructed with sound absorbing foamed polysty- <br />rene and polyethylene insulation. <br />E. Fan: <br />1. The fan shall be direct -drive turbo fan type with 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 from 0.06 to 0.12 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. Filter: <br />1. The return air shall be filtered by means of a washable long -life filter with <br />mildew proof resin. <br />G. 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 17 FPI de- <br />sign completely factory tested. <br />4. The refrigerant connections shall be flare connections and the conden- <br />sate will be 1 -1/32 inch outside diameter PVC. <br />5. A condensate pan shall be located under the coil. <br />6. A condensate pump with a 21 inch lift shall be located below the coil in <br />the condensate pan with a built in safety alarm. <br />7. A thermistor will be located on the liquid and gas line. <br />H. 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 />I.
