DESCRIPTION
YORK Sunline Plus™ units are high efficiency, convertible, single package air conditioners with a common cabinet and a common roof curb for the 3, 4 and 5 ton sizes. The units were designed for light commercial and 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 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 field--installed acces- sories.
Both bottom and side duct connections are available without having to swap panels. The installer simply removes the duct covers for the desired configuration. Economizers may be used on either bottom and side duct applications with no modifications required.
All models include a 5--year limited warranty on compres- sors, a 10--year limited warranty on gas--fired heat exchang- ers and a 1--year limited warranty on other parts.
FEATURES
COMMON FOOTPRINT/COMMON CABINET -- All model sizes and configurations share a common cabinet and a com- mon 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 of at least 11.0 SEER and gas / electric models have an AFUE as high as 80.9%. All efficiencies exceed legislated minimum levels and provide low operating costs.
CONVERTIBLE AIRFLOW DESIGN -- Both the side and bot- tom 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! Con- vertible airflow design allows maximum field flexibility and minimum inventory.
FACTORY--INSTALLED 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 all models from the factory for complete airflow flexibility.
FIELD--INSTALLED ACCESSORIES -- Accessories were designed for quick and easy installation. The motorized damper and economizers simply slide in, and electrical con- nections 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 damp- ers 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. An insu- lated 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 ºF.
Propane, high altitude and low NOx kits are also available to cover all gas heating applications.
WIDE RANGE OF INDOOR AIRFLOWS -- All models oper- ate 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 pro- vided so that an overhead crane can be used to place the units on a roof.
SYSTEM PROTECTION -- Internal overload protection is standard on all compressors. Every unit has a liquid line filter- -drier, high and low pressure/loss of charge switches and a suction line freezestat to protect all system components. All units will provide cooling at ambient temperatures down to 45 ºF.
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
