50.TGY (95) SINGLE PACKAGE COOLED CONDITIONERS DCE 0, 0, 00 & DCE 07 0, 0, 00 & 07, AND 5 NOMINAL TONS (0 SEER) AND NOMINAL TONS (9 EER) SHOWN SUNLINE 000 DESCRIPTION YORK Sunline 000 units are convertible single package air conditioners with a common cabinet and a common roof curb for the,, 5 and ton sizes. The units were designed for residential, light commercial and commercial applications. They can easily be installed on a roof curb, slab, roof jack or frame. All units are selfcontained and assembled on rigid full perimeter base rails with fork lift slots on three sides and holes for overhead rigging. Every unit is completely piped, wired, charged and tested at the factory to provide for a quick and easy field installation. The units are available in cooling only, and cooling with gas heat. Electric heaters are available as fieldinstalled accessories. The cabinet is constructed of galvanized steel, painted with long lasting, durable, and aesthetically pleasing power paint. Paint finish meets 7 hour salt spray tests per ASTMB7 standards. All models include a 5year limited warranty on compressors and electric heating elements, a 0year limited warranty on gasfired heat exchangers and a year limited warranty on all replacement parts. FEATURES COMMON FOOTPRINT/COMMON CABINET All model sizes and configurations share a common cabinet and a common roof curb. The installer has the flexibility of setting one curb and placing the proper tonnage unit on that curb after the internal load has been determined. He can even decide between gas or electric heat after the curb has been set. HIGH EFFICIENCY All units have a high cooling efficiency, and gas / electric models have a minimum AFUE of 0%. All efficiencies exceed legislated minimum levels and provide low operating costs. CONVERTIBLE FLOW DESIGN Both the side and bottom duct openings are covered when they leave the factory. If a side supply / side return is desired, you simply remove the two side duct covers from the outside of the unit and discard them. If a bottom supply / bottom return is desired, you simply remove the two knockout panels from the base of the unit and discard them. No panel cutting or swapping is required! Convertible airflow design allows maximum field flexibility and minimum inventory. Economizers may be used on either bottom and side duct applications with no modifications required. FACTORYINSTALLED OPTIONS Economizers can be installed at the factory. The economizers are shipped installed and wired. Only the rain hood needs to be field assembled and installed. Field labor dollars can be saved by having the components arrive already installed. Adjustable belt drive blowers are available on most models from the factory for complete airflow flexibility. FIELDINSTALLED ACCESSORIES Accessories were designed for quick and easy installation. The motorized damper and economizers simply slide in, and electrical connections are made by modular plugs. Electric heaters mount easily, and knockouts are provided in the internal partitions to connect the elements to the control box single point kit. The " high roof curb is shipped knocked down. An insulated deck is not required because the bottom of the unit is insulated. Low ambient controls are available to provide stable unit operation at outdoor temperatures down to 0 F. Propane, high altitude and low NOx kits are also available to cover all gas heating applications. WIDE RANGE OF INDOOR FLOWS All, and 5ton models operate over a wide range of design conditions with a speed directdrive fan motor. The ton unit has a single speed directdrive fan motor. Beltdrive blowers are also available on all, and 5ton models and on ton, phase models. FULL PERIMETER BASE RAILS The permanently attached base rails provide a solid foundation for the entire unit and protect the unit during shipment. The rails provide fork lift access from sides, and rigging holes are also provided so that an overhead crane can be used to place the units on a roof. Cont d.
50.TGY FEATURES CONT D. SYSTEM PROTECTION Crankcase heat and internal overload protection are standard on all compressors. Every unit has a liquid line filterdrier, high and low pressure/lose at charge switches and a suction line freezestat to protect all system components. All units will provide cooling at ambient temperatures down to F. UTILITY CONNECTIONS MADE EASY Gas and electric utility knockouts are provided in the unit base as well as the side of the unit. A clearly identified location is provided to mount a field supplied electrical disconnect switch. Utility connections can be made quickly and with a minimum amount of field labor. SIMPLE CONTROL CIRCUIT A low voltage printed circuit board contains a compressor lockout indicator light and a low voltage terminal strip. An additional set of pin connectors is also provided to simplify the field interface of external controls. Matenlock plug connectors are used where line and low voltage wires pass thru internal bulkheads. This allows for easier troubleshooting and component replacement. The electrical control box is not located in the compressor compartment so the access cover can be removed for troubleshooting without affecting the normal system operating pressures. All wiring internal to the unit is color/number coded. FILTERS Units are shipped with " disposable filters. The unit filter racks can accommodate " or " filters without any modifications.

As the outdoor air intake dampers open, the return air dampers close. The changeover from mechanical refrigeration to economizer operation is determined by a single input electronic enthalpy control or by a dual input electronic enthalpy control. Simultaneous compressor and economizer operation is also possible. The single enthalpy system contains a sensor that monitors the outdoor air which automatically operates the damper actuator allowing the dampers to open or close. FIELDINSTALLED ACCESSORIES 7 07 95 SINGLE INPUT ELECTRONIC ENTHALPY ECONOMIZER Includes a slidein / plugin damper assembly with fully modulating spring return motor actuator capable of introducing up to 00% outdoor air, one outdoor air electronic enthalpy sensor and a rain hood with filters. The rain hood is painted to match the basic unit and must be fieldassembled before installation. Economizer dampers are % low leakage type. DUAL INPUT ELECTRONIC ENTHALPY ECONOMIZER Includes the same damper system and rain hood with filters as described for a single enthalpy economizer except this accessory contains two enthalpy sensors. It uses a differential enthalpy control that compares the outdoor air versus the return air. The logic module then optimizes the economizer operation for additional savings over the single input economizer. MOTORIZED DAMPER Includes slidein / plugin damper assembly with position springreturn motor actuator and a rain hood with permanenttype filters. The outdoor air dampers open when the indoor fan motor is energized. The rain hood is shipped knocked down and must be field assembled.

The logic module compares the inputs from both sensors and switches to economizer operation whenever the outdoor air is cooler than the return air for maximum efficiency of the economizer system. The economizer is completely wired and installed at the factory. Only the outdoor air hood, including its filters, need be assembled and installed in the field. BELT DRIVE BLOWERS: Adjustable beltdrive blowers providing maximum flexibility to handle many airflow requirements, are available on all, and 5 ton models and on ton, phase models. shifted for the desired unit duct arrangement. No insulated deck is required because the unit underside is insulated. START ASSIST KIT Provides increased starting torque for single phase units in areas with low voltage conditions. It contains a.5 OHM PTCR temperature resistor with a support clip and hardware for mounting. LOW AMBIENT KIT A head pressure controller maintains stable system operation by reducing the speed of the condenser fan motor when the outdoor temperature is between and 0 F. Condenser fan motors with ball bearings and heavier windings are also available for these low ambient applications. ANTIRECYCLE TIMER A timer to prevent the unit compressor from short cycling. It assures a 5minute offtime between compressor cycles. PROPANE CONVERSION KIT Converts a gasfired heater from natural gas to propane. It contains main burner orifices, a pilot orifice and a regulator spring. LOW NOx KIT (natural gas furnaces only) Contains five stainless steel expanded metal sheets for mounting into the heat exchanger tubes to meet the California low nitrous oxide emission requirements.
