To ensure the liquid refrigerant does not flash when supplying to the vari- <br />ous indoor units, the circuit shall be provided with a sub - cooling feature. <br />11. Oil recovery cycle shall be automatic occurring 2 hours after start of oper- <br />ation and then every 8 hours of operation <br />12. The condensing unit shall be capable of heating operation at 0 °F dry bulb <br />ambient temperature without additional low ambient controls or an auxilia- <br />ry heat source. <br />Unit Cabinet: <br />1. The condensing unit shall be completely weatherproof and corrosion re- <br />sistant. The unit shall be constructed from rust - proofed mild steel panels <br />coated with a baked enamel finish. <br />C. Fan: <br />1. The condensing unit shall consist of one or more propeller type, direct - <br />drive 350 or 750 W fan motors that have multiple speed operation via a <br />DC (digitally commutating) inverter. <br />Model Number <br />Fan Motor Output W & Quantity <br />RXYQ72TYDN <br />750 x 1 <br />RXYQ96TYDN <br />350 x 2 <br />RXYQ120TYDN <br />350 x 2 <br />RXYQ144TYDN <br />750 x 2 <br />RXYQ168TYDN <br />750 x 2 <br />RXYQ192TYDN <br />350 x 2 + 750 x 1 <br />RXYQ216TYDN <br />350 x 2 + 350 x 2 <br />RXYQ240TYDN <br />350 x 2 + 350 x 2 <br />RXYQ264TYDN <br />350 x 2 + 750 x 2 <br />RXYQ288TYDN <br />750 x 2 + 750 x 2 <br />RXYQ312TYDN <br />750 x 2 + 750 x 2 <br />RXYQ336TYDN <br />750 x 2 + 750 x 2 <br />RXYQ360TYDN <br />350 x 2) + 350 x 2) + 350 x 2 <br />RXYQ384TYDN <br />350 x 2) + 350 x 2) + 750 x 2 <br />RXYQ408TYDN <br />(350 x 2) + (750 x 2) + (750 x 2) <br />The condensing unit fan motor shall have multiple speed operation of the <br />DC (digitally commutating) inverter type, and be of high external static <br />pressure and shall be factory set as standard at 0.12 in.
