DESCRIPTION

YORK Sunline 2000 Heat Pumps are convertible single package units with a common cabinet and common roof curb for the 3, 4 and 5 ton sizes. The units were designed for residential and light commercial applications. They 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 with supplemental electric heaters 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.

FEATURES

CONTROLS -- These heat pumps utilize a unique time-- temperature defrost circuit which adjusts the time between defrost cycles based on the outdoor temperature to provide optimal comfort control and ensure reliable operation. The ambient--modified, time--temperature defrost control extends the time below 35°F and shortens the time above 35°F. The nominal defrost times are field adjustable to 50, 80 and 110 minutes. The defrost time is initiated and terminated by a liquid line control with a 10 minute override limit built into the defrost control.

COMMON FOOTPRINT/COMMON CABINET -- The 3, 4 and 5 ton units all share the exact same 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.

HIGH EFFICIENCY -- All units have a minimum SEER of 10, a COP of 3.0 (high) and 2.0 (low) and an HSPF as high as 7.3. 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 can be installed at the factory. They are shipped installed and wired. The outdoor air hood needs only to be field assembled and installed.

Adjustable belt--drive blowers are available on most models from the factory for complete air flow flexibility.

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 motorized air damper includes a slid--in/plug--in damper assembly with a rainhood and filters. The outdoor air dampers open when the indoor fan motor is energized. The damper is capable of providing 0% through 100% of outdoor return air opening.

The manual outdoor damper provides 0% through 35% or 0% through 100% of return air opening (field adjustable). Designed for duct mounted side or bottom supply/return applications. Includes rain hood assembly and filter.

The 14" high roof curb is shipped knocked down. A roof curb deck is not required because the bottom of the unit is insulated.

WIDE RANGE OF INDOOR AIRFLOWS -- All models operate over a wide range of design conditions with a 3--speed direct-- drive fan motor. Belt--drive blowers are also available on all 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 3 sides and rigging holes are also provided so that an overhead crane can be used to place the units on a roof.

FEATURES - CONT'D.

SYSTEM PROTECTION -- Crankcase heaters and internal compressor protection are standard on all compressors. Every unit has a liquid line filter--drier, low pressure switch, high pressure switch and high temperature switch to protect all system components. A suction line freezestat is supplied on all three--phase units to protect against loss of charge and coil frosting due to low economizer outdoor air temperature while the compressor is running. All units will provide cooling at ambient temperatures down to 45°F.

UTILITY CONNECTIONS MADE EASY -- 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

036-21564-002-A-0404

field supplied electrical disconnect switch. Utility connections can be made quickly and with a minimum amount of field labor.

SIMPLE CONTROL CIRCUIT -- Mate--n--lock 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.

AIR FILTERS -- Units come standard with 1" throwaway filters. The unit filter racks can accommodate 1" or 2" filters without any modifications.

SEER = Seasonal Energy Efficiency Ratio - the total cooling output in BTU's during a normal annual usage period for cooling divided by the total electric power input in watt-hours during the same period.

EER = Energy Efficiency Ratio-the cooling capacity in BTU's per hour (BTUH) divided by the power input in watts at any given set of rating conditions, expressed in BTUH per watt (BTUH/watt).

COP = Coefficient of Performance - the total heating capacity provided by the refrigeration system, including circulating fan heat but excluding supplementary resistance (BTU's per hour) divided by the total electric input (watts) x 3.412.

	1These capacities are gross ratings. For net capacity, determine the KW of the supply air blower motor from the Blower Performance Table, multiply this value by
	3.415 MBH / KW to determine the motor heat, and deduct this heat from the gross capacity of the unit.
	2These ratings include the compressor and the outdoor fan motors but not the supply air blower motor. The total outdoor fan motor power input is 0.35 KW.

1These capacities are gross ratings. For net capacity, determine the KW of the supply air blower motor from the Blower Performance Table, multiply this value by 3.415 MBH / KW to determine the motor heat, and deduct this heat from the gross capacity of the unit.

2These ratings include the compressor and the outdoor fan motors but not the supply air blower motor. The total outdoor fan motor power input is 0.35 KW. Refer to the Blower Performance Table for the KW of the supply air blower motor.
