Unit Top The top cover shall be one piece construction or,where seams exist,it shall be double-hemmed and gasket-sealed. The ribbed top adds extra strength and enhances water removal from unit top. Filters Throwaway filters shall be standard on all units.Optional 2-inch MERV 8 and MERV 13 filters shall also be available. Compressors All units shall have direct-drive,hermetic,scroll type compressors with centrifugal type oil pumps.Motor shall be suction gas-cooled and shall have a voltage utilization range of plus or minus 10 percent of unit nameplate voltage.Internal overloads shall be provided with the scroll compressors. Dual compressors are outstanding for humidity control,light load cooling conditions and system back-up applications.Dual compressors are available on 7%-10 ton models and allow for efficient cooling utilizing 3-stages of compressor operation for all high efficiency models. Notes: Crankcase heaters are optional on YSC(036,048,060,072,090,102,120);standard on YHC(036,048,060,072,092,102,120). Indoor Fan The following units shall be equipped with a direct drive plenum fan design(T/YSC120E,TNHC092,102,120E).Plenum fan design shall include a backward-curved fan wheel along with an external rotor direct drive variable speed indoor motor.All plenum fan designs will have a variable speed adjustment potentiometer located in the control box.3-5 ton units(standard efficiency 3-phase or high efficiency 3-phase with optional motor)are belt driven,FC centrifugal fans with adjustable motor sheaves.3-5 ton units(1-phase or high efficiency 3-phase)have multispeed,direct drive motors.All 6-8%ton units(standard efficiency)shall have belt drive motors with an adjustable idler-arm assembly for quick-adjustment to fan belts and motor sheaves.All motors shall be thermally protected.All 10 tons and 7'/:-8'/z(high efficiency)have variable speed direct drive motors.All indoor fan motors meet the U.S.Energy Policy Act of 1992(EPACT). Outdoor Fans The outdoor fan shall be direct-drive,statically and dynamically balanced,draw-through in the vertical discharge position.The fan motor shall be permanently lubricated and shall have built-in thermal overload protection. Evaporator and Condenser Coils Internally finned,5/16"copper tubes mechanically bonded to a configured aluminum plate fin shall be standard.The microchannel type condenser coil is standard for the T/YSC 10 ton models and 7%ton high efficiency models.The microchannel type condenser coil is not offered on the 7%ton dehumidification model.Due to flat streamlined tubes with small ports,and metallurgical tube-to-fin bond,microchannel coil has better heat transfer performance.Microchannel condenser coil can reduce system refrigerant charge by up to 50%because of smaller internal volume,which leads to better compressor reliability.Compact all-aluminum microchannel coils also help to reduce the unit weight.All-aluminum construction improves re- cyclability.Galvanic corrosion is also minimized due to all aluminum construction.Strong aluminum brazed structure provides better fin protection.In addition,flat streamlined tubes also make microchannel coils more dust resistant and easier to clean.Coils shall be leak tested at the factory to ensure the pressure integrity.The evaporator coil and condenser coil shall be leak tested to 600 psig.The assembled unit shall be leak tested to 465 prig.The condenser coil shall have a patent pending 1+1+1 hybrid coil designed with slight gaps for ease of cleaning.A removable,reversible,double-sloped condensate drain pan with through the base condensate drain is standard. Controls Unit shall be completely factory-wired with necessary controls and contactor pressure lugs or terminal block for power wiring.Unit shall provide an external location for mounting a fused disconnect device.A choice of microprocessor or electromechanical controls shall be available. Microprocessor controls provide for all 24V control functions.The resident control algorithms shall make all heating,cooling,and/or ventilating decisions in response to electronic signals from sensors measuring indoor and outdoor temperatures.The control algorithm maintains accurate temperature control,minimizes drift from set point,and provides better building comfort.A centralized microprocessor shall provide anti-short cycle timing and time delay between compressors to provide a higher level of machine protection.24-volt electromechanical control circuit shall include control transformer and contactor High Pressure Control All units include High Pressure Cutout as standard.
