1 TGY (598) SINGLE PACKAGE GAS / ELECTRIC UNITS AND SINGLE PACKAGE AIR CONDITIONERS D3CE/D3CG10 & D4CE/D4CG090, 10 & /, 8-1/, 10 AND 1-1/ NOMINAL TONS EER DCG MODEL SHOWN SUNLINE 000 DESCRIPTION YORK Sunline 000 units are convertible single packages with a common footprint cabinet and common roof curb for all 7-1/ thru 1-1/ ton sizes. All units have dual compressors with dual independent refrigeration circuits. The units were designed for light commercial applications and can easily be installed on a roof curb, slab, roof jack or frame. All units are self-contained and assembled on rigid full perimeter base rails allowing for 3-way fork lift access and overhead rigging. Every unit is completely charged, wired, piped and tested at the factory to provide for a quick and easy field installation. The units are available in the following configurations: cooling only, cooling with electric heat and cooling with gas heat. Electric heaters are available as field-installed accessories. Both down and side discharge airflows are available without having to swap panels. The installer simply removes the duct covers for the desired configuration. Economizers may be used on either side or down discharge applications with no modifications required. All models include a 1-year limited warranty on the complete unit. Compressors and electric heater elements each carry an additional 4-year warranty. Aluminized steel tubular heat exchangers carry an additional 9-year warranty. FEATURES COMMON FOOTPRINT / COMMON CABINET - All model sizes and configurations share the exact same footprint cabinet - and therefore the same roof curb. You now have the flexibility of setting one curb and, after the internal load has been determined, placing the proper tonnage unit on that curb. You can even decide between gas or electric heat after the curb has been set. HIGH EFFICIENCY - All units have a minimum EER of 8.5. Gas / electric units have electronic spark ignition and power vented combustion with steady state efficiencies as high as 81.0%. These efficiencies exceed all legislated minimum levels and provide low operating costs. CONVERTIBLE AIRFLOW 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 / return is desired you simply remove the two bottom duct covers and discard them. No panel cutting or swapping is required! Convertible airflow design allows maximum field flexibility and minimum inventory. FACTORY INSTALLED OPTIONS - Economizers,and alternate indoor fan motors can be installed at the factory. The economizers are shipped installed and wired. The outdoor air hood needs only to be field assembled and installed. Field labor dollars can be saved by having the components arrive already installed. FIELD INSTALLED 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 14" high roof curb is shipped knocked down. The roof curb has an insulated deck. Low ambient controls are available to provide stable unit operation at outdoor temperatures down to 0 F. Propane and high altitude kits are also available to cover all gas heating applications. MOTORIZED AIR DAMPER - Includes slide-in/plug-in damper assembly with rainhood and filters. The outdoor air dampers open when the indoor fan motor is energized. Damper is capable of providing 0% thru 100% outdoor return air opening. MANUAL OUTDOOR DAMPER - Provides 0% thru % or 0% thru 100% of return air opening (field adjustable). Designed for duct mounted side or bottom supply/return applications. Includes rain hood assembly and filters WIDE RANGE OF INDOOR AIRFLOWS - All indoor fan motors are belt-drive type providing maximum flexibility to handle most airflow requirements. Factory-installed alternate indoor fan motors are available on some models for high static applications. 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 3 sides and rigging holes are also provided so that an overhead crane can be used to place the units on a roof. Cont d.

2 TGY FEATURES - CONT D. UTILITY CONNECTIONS MADE EASY - Gas and electric utility knockouts are provided in the unit underside 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 low voltage terminal strip. An additional set of pin connectors is also provided so that field interface of external controls will be simplified. A suction line freezestat is supplied on all units to protect against loss of charge and coil frosting due to low economizer outdoor air temperature while the compressors are running. 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. AIR FILTERS - Units come standard with " throwaway filters. The unit filter racks can accommodate 1" or " filters without any modifications. SYSTEM PROTECTION - Crankcase heaters and internal compressor protection are standard on all compressors. Every unit has liquid line filter-driers, high pressure switches and suction line freezestats to protect all system components. The units will operate down to 45 F without any additional low ambient controls.

22 TGY FACTORY INSTALLED OPTIONS ECONOMIZERS: Units equipped with the factory-installed economizer option have dampers that are positioned by a spring return, fully modulating damper actuator capable of introducing up to 100% outdoor air. 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. Economizer dampers are % low leakage type. A barometric relief damper is shipped in the return air compartment for field installation. 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. The dual enthalpy system contains a second sensor that monitors the return air in addition to monitoring the outdoor air described above for a single enthalpy system. The logic module compares these two values and modulates the dampers providing the 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. ALTERNATE INDOOR FAN MOTORS: Larger horsepower motors are available on most models to handle higher static pressure applications. FIELD-INSTALLED ACCESSORIES SINGLE INPUT ELECTRONIC ENTHALPY ECONOMIZER - Includes a slide-in / plug-in damper assembly with fully modulating spring return motor actuator capable of introducing up to 100% outdoor air, one outdoor air electronic enthalpy sensor and a rainhood with filters. The rainhood is painted to match the basic unit and must be field-assembled before installation. Economizer dampers are % low leakage type. DUAL INPUT ELECTRONIC ENTHALPY ECONOMIZER - Includes the same damper system and rainhood with filters as described for a single enthalpy economizer above 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 AIR DAMPER - Includes slide-in / plug-in damper assembly with rainhood and filters. The outdoor air dampers open when the indoor fan motor is energized. Damper capable of providing 0% thru 100% of outdoor return air opening. MANUAL OUTDOOR DAMPER - Provides 0% thru % or 0% thru 100% of outdoor return air opening (field adjustable). Designed for duct mounted side or bottom supply/return applications. includes both hood assembly and filters. ELECTRIC HEATERS - Include nickel chromium elements, a terminal block, fuses (where required by UL), all the necessary connectors and hardware. All heaters utilize single point power supply hookup. Capacities of 9, 18, 4, 36 and 54 KW heating are available. FUSE BLOCK KIT - This kit contains a fuse block including the fuses and is available for the 9 and 18 KW 4-volt heater kits. This kit satisfies the Chicago code requirements. ROOF CURB - This 14" high full perimeter roof curb is shipped knocked down for field assembly. Its duct supports and insulated condensing section deck can be reversed to connect the ductwork on the opposite end. LOW AMBIENT KIT - Head pressure controllers maintain stable operation by reducing the speed of the condenser fan motors when the outdoor temperature is between 45 and 0 F. Condenser fan motors with ball bearings and heavier windings are available for these low ambient applications. ANTI-RECYCLE TIMER - A timer to prevent unit compressors from short cycling. It assures a 5-minute off-time between compressor cycles. PROPANE CONVERSION KIT - Converts a gas-fired heater from natural gas to propane. It contains main burner orifices, a pilot orifice and a gas valve. GAS PIPING - This kit contains 3/4" pipe nipples, fittings and gas cock (including panel access gaskets) required for bottom gas supply connection with external shut-off. HIGH ALTITUDE CONVERSION (NATURAL AND PROPANE) - Provides orifices for proper furnace operation at altitudes up to 6,000 ft. For propane applications, the propane conversion kit will also be required. WALL THERMOSTAT - The units are designed to operate with 4-volt electronic and electro-mechanical thermostats. All electric / electric and gas / electric units operate with two stage heat / two stage cool thermostats (with or without an economizer). Unitary Products Group
